Belt conveyor maintenance and repair

Belt conveyor belt conveyor is also called, is the ideal continuous and efficient coal transportation equipment, and other transport equipment (such as locomotive class),

compared with the long distance 90 degree conveyor, large volume, continuous conveyor, etc., and reliable operation, easy to automate and centralize control,

Especially for high-yield and efficient mine, coal mining belt has become mechatronics technology and equipment of key equipment.
Caesar conveyor belt material is a common problem, the reasons are multi-faceted. Smart Electrical remind you focus is to strengthen the daily care and maintenance.
1 reprint reprint scattering material at the point of the point spread mainly in the fall feed hopper, guide trough, etc.. If severe overload Turn conveyor, belt conveyors

guide trough backgauge rubber apron damaged steel guide trough at design time far away from the belt so that the material is relatively long rubber apron out of guide trough

. The situation can be transported in the control capacity, enhance maintenance be resolved.
(2) when the concave section of the belt material spreading vacant belt concave segment interval when the radius of curvature smaller concave segment will generate vacant belt,

then the belt into a trough situation changes, because the belt has left the trough idlers, generally groove angle becomes small, so that part of the material spread out.

Therefore, in the design

Stage should be possible to use a larger radius of curvature of the concave section to avoid this from happening. If the mobile mechanical ship loader, stacker-reclaimer device

in order to shorten the trailer and the concave section designed here no arc transition interval, when the belt width smaller redundancy selection easier Caesar

Material.
3 when the scattering material deviation belt deviation scattering material is because when the belt is running two edge height changes, while high, while the other side is low,

the low side of the material from spreading out, processing method is to adjust belt deviation.

Improve production line efficiency for the role of ease

Industrial production plants, there are many techniques is the use of the pipeline, the pipeline was produced in 1769, the original division of labor, workers must work

according to a fixed rhythm of work, subject to a unified labor management, improve the integration of production processes, also saves labor

The number of factory workers to achieve a Turn conveyor certain degree of automated production, high rates of return. So the pipeline for operators, it is a useful improvement.
Pipeline generally refers to a specific line stations can be transmitted continuously on the workpiece, the workpiece handling assembly, also known as the assembly line conveyor

line. In accordance with the transfer device series can be roughly divided into the belt line, chain conveyor, multiple chain line, 90 degree turn conveyor processing assembly line, plug wire

, Assembly lines, packaging lines, mesh belt conveyor line, suspension lines and drum lines, multiple chain line, plate chain which nine categories pipeline. In general, then

that includes traction, bearing components, drives, tensioning device, redirecting means and the supporting parts. , To the transport

Line the words are generally fixed. Then the words of pipeline transportation capacity, making long distance, but also in the transportation process while completing a number of

process operations, so widely used.
In general, then pipelining is an effective combination of people and machines that can be most fully embodies the assembly line equipment, production flexibility, it will

conveyor systems, pallet and online is that you can plane, an effective combination of on-line testing equipment production to meet the multi-species products flow

Water delivery requirements. Water transmission line transmission methods are synchronous transmission compulsory or non-synchronous transmission flexible type, depending on the

configuration of choice, then that can achieve the requirements for assembly and transport. For mass production of conveyor line integral in the enterprise, the enterprise

section

Overload protection for roller conveyors

   Roller conveyor belt conveyor including all components must be protected against overload . Starting 90 degree conveyor excessive loading conveyor, motor and drive must be sufficiently large ,

the maximum torque can be used to adjust the restriction device to eliminate accidental start or run the conveyor possibility of excessive load . Driving means may be too large

torque to the tape , the tape can also plastic chain conveyor impact load reducer and motor mechanical parts inflammatory effects, therefore , exclude the possibility of overloading the drive means

mounted on the output torque limit and control components. This component of the dynamic response requirements can eliminate tape principal stress and excitement of the moment

rushed through the torque limiter on the impact of the motor reducer machine .

The origin of roller conveyor

Roller conveyors in the History : Ancient Chinese high drum water overturned cars and mentioning , is the modern scraper bucket elevators and conveyors prototype ; 17th century

, began to apply ropeway transport Turn conveyor bulk materials ; 19th century , a variety of modern structural conveyor has emerged.
1868 , in the UK there has been belt ; 1887 , in the United States appeared screw conveyor ; 1905 , appeared in Switzerland steel belt conveyor ; 1906 , in the United Kingdom

and Germany appeared inertia 90 degree turn conveyor. Thereafter , conveyors manufactured by mechanical , electrical , chemical and metallurgical industries impact of technological advances ,

and constantly improve gradually from the inside to complete the delivery of the workshop , developed to accomplish within the enterprise , between enterprises and even between

cities material handling, become material mechanization and automation of handling systems indispensable component.

Conveyor its overview of the parameters

Conveyor as the moment the most widely used business equipment conveyors , roller conveyors with high reliability, high efficiency , simple structure, easy to assemble the finished product can be realized in various industries , material handling , sorting line production and other processes. Usually called roller conveyor roller conveyor , roller

Conveyors and roller conveyors . Flexible Roller Conveyor has no power , product release type , power and other forms. Can also be a turn -style transportation of materials, stainless steel , aluminum alloy materials village stretching its body can also be transported material is a versatile transport machinery and equipment . Material handling is guaranteed thing

Smooth flow of the effective operation of the Automatic Sorting Machine system is an important part , therefore , to complete the delivery of material handling machinery, logistics system design has become the focus of the project planners . In the fixed path transport ( such as production logistics , product flow between the various processes , warehousing systems

Transceiver and cargo distribution center picking shipping and other ) , mostly using roller, belt or chain and other types of transport machinery, namely unit load conveyors, roller type which is more common. Roller Conveyors according to its power source can be divided into two categories. One for the

Power type , the roll is rotated by the power . Usually in the motor as the driving force , through a belt , chain or gear driven roller rotates , thereby bringing forward delivery matter ; also owns its own electric power roller conveyors , conveyor rollers that have their own power , from

The simple and compact structure makes the conveyor , but because the price is expensive, currently used less. Another type of gravity roller conveyor . Such a roller conveyor there is no power , but the roller into a suitable inclination angle , the roller track of the object to be transported under the action of gravity

Own decline , reaching the purpose of transportation .

Variable speed conveyor equipment advantages and disadvantages

Transportation equipment is often used on the drive to control, but there are advantages and disadvantages of frequency control , the following Chengdu solid Nashville for everyone explain in detail : 1 , speed , high efficiency, high- speed mode belongs . This is due to a 90 degree turn conveyor change in frequency , the motor is still near synchronous speed

Run , remained rated slip . Only in the frequency converter system will produce variable flow losses , as well as the impact of higher harmonics , motor loss increases , and thus the efficiency decline. 2 , wide speed range , generally up to 20:1 , and in the entire speed range with high

Speed ??efficiency. So inverter for wide plastic chain conveyor speed range , and often run in the low load condition of the occasion . 3, the mechanical properties of hard, in the absence of automatic control, the speed change rate below 5% ; When using automatic control , can do high-precision operation , the speed fluctuation rate control

System at 0.5% | ~ 1% or so. 4, the inverter device in case of failure , you can quit running , replaced by direct power supply, pump or fan may continue to remain in operation . 5, can double as the boot device , namely through the power inverter to a rotational speed of the motor starts , and then disconnect the power inverter,

Motor can be connected directly to the power frequency of the pump or fan to accelerate to full speed. In power supply to the power switch frequency , generally 400% to 500 % of the impact of current generation, the instantaneous grid voltage drop , motor subjected to mechanical shocks. To prevent this phenomenon, in the motor

And work in parallel between a start frequency power reactors, in order to suppress inrush current at start of production. If the original motivation for the synchronous motor , you need a " synchronous switching ."

How to improve the performance of idlers

Idler roller conveyors as a key component in the material transport 90 degree conveyor belt to withstand the resistance of more than 70% , as the utilization of large , large frequency of

replacement parts , in the selection, use , and maintenance are required in consider some aspects to improve the performance of idlers . Next

Side effects , I will introduce the main reason for the use of performance roller what .
First, the sealing effect is not good :
Sealing roller is used within the axial non-contact labyrinth seal , which is characterized by the inner and outer seal member is formed between the gap to achieve a small

tortuous sealing against dust is better, but the waterproof effect is poor, and mine vertical conveyor production conditions are dusty , and dust with water ,

So used roller seal must be dust-proof , waterproof effect. If the water will corrode the inner roller bearings, into the dust will damage the bearings , and ultimately affect

the service life of the roller .
Second , roller shaft concentricity difference:
Drawing roller shaft axis , which is characterized by a surface roughness and dimensional accuracy can be achieved without processing requirements of the drawings , with up
Convenient, saving labor . However, due to the optical axis of the production drawing tire tool wear due to factors such as dimensional accuracy is unstable, often have exceeded

the phenomenon , coupled with the transport process could easily lead to bend , so that the roller shaft concentricity deviation , roller shaft two side installation of the

bearing clearance can not be guaranteed ,

Thereby rotating roller resistance increases , affecting the life of the roller .
Third , bearing concentricity difference:
Roller bearing is used for stamping , and tube skin with the Department without processing , bearing sleeve welded directly on the skin . Stamping bearing skin is not round or

barrel at the end with the inequalities are easy to cause skin after welding ends of the cylinder bearing different axes , resulting in reduced bearing clearance , rotation

Resistance increases, the rotation is not flexible.
Idlers we all understand the importance of , and that the choice for idlers need to seriously consider seriously. The above three points that need to refer to when selecting

roller aspects , but also in the use and maintenance of rollers that need focused attention on three points .

How to improve the efficiency of the transport roller conveyors

   Conveyor roller is the one of the main components , which can be used in addition to roller conveyor component parts and, in the other transmission equipment also has a wide

range of applications . As Flat belt conveyor build one of the most important , it is what constitutes the drum is how to improve

The efficiency of the conveyor .
   Conveyor roller is an important component of the delivery , performance and structural characteristics determine the operation efficiency of roller conveyors . Drum runtime

by electric drive chassis for various forms of efficient transport operations, improve delivery performance, while facilitating the application operation.
   With the improvement of the technical requirements rollers , Elevator conveyor possess the advantages of more and more. Roller cover mainly by the cover , the bearing and the

brush plates, with high abrasion resistance properties of the roller cover can effectively reduce the roller conveyor at a high load and high speed operation the frictional

resistance ,

Reduce wear and extend the service life of the drum .
   In addition , the roller surface of the conveyor roller cover with high wear-resistant material also installed production guard, to reduce the operation of the friction

roller cover to prevent the cylinder cover from external impact force by the crack , damage , the roller can be normal operation. If the roll end

Does not cover the surface of the shield , the future to ensure the safe operation of the drum , the need to use high-strength steel sections made ??of cover, and cover the

surface of the drum galvanized treatment to improve the abrasion resistance drum cover and mechanical strength.

Rapid development of the future development tends Belt Green

    Belt Conveyor is widely used in metallurgy, coal, transport, water , chemicals and other sectors in the food processing powered roller conveyor production process , but also play a pivotal

role , it is because it has a transmission capacity, simple structure , easy maintenance, low cost, versatility , etc.

Advantages . Domestic belt entered a rapid development stage , and now the market demand is very big. In some areas has gradually begun to replace the belt locomotives and motor

transport .
Belt trends
    The direction of the large-scale development, including large transmission capacity and large single length and other aspects. Now the world's longest hydraulic conveying

device has more than 400 kilometers in length , the longest single skate roller conveyor length is close to 15 km , and the two cities have emerged Contact

City of belt conveyors road. The world's major developed countries are also being developed with a long-distance, large-capacity transmission capacity continuous conveyor

structure to a higher performance, function better direction . In extreme temperature environments and corrosive , radioactive and other environments, and can

Transporting flammable , heat, sticky materials such as conveyors.
Conveyors can meet the automation control requirements.
    The maximum extent possible to reduce energy consumption of energy and , calculate the standard material handling according to one kilometers 1 tons of energy to be consumed

, which is the most important in the future development direction. Reduce conveyor at work for a variety of pollution, protect the ecological environment as the goal.

Transmission belt

Sending machine protection systems must also bound to the development and testing technology, communications technology, and automation control technology development closely.

All in all, the structure of belt conveyor , conveyor belt speed capability and have different levels of development, especially since the bulk conveying system for bulk

material

Belt conveyor increasingly high performance requirements . With the domestic mining increased automation , growing port operations , power generation on the rise , food

production and processing industry , and other areas of the market continues to develop, domestic materials transport industry will continue to grow

. The industry believes that the future large-scale development will be toward the belt , to expand the scope , automatic sorting of materials , reduce energy consumption,

reduce pollution and other aspects of development .

Roller conveyor can be selected based on carrying capacity

   Roller conveyor machinery and equipment is an important accessory , roller conveyor roller body production should mainly by the early cars, early school statically balanced

shaft interference fit welding , precision balancing school and other process group , widely used in a variety of packaging, transfer , and sorting heavy duty conveyor equipment . Roll

forming, the

To rust and corrosion , support , wear needs , the need to send or coated on the surface outside the grounds , such as painting, Jue plastic , chrome and oxidation processes.
   Roll quality directly affect the normal operation of the conveyor and operating costs . Roller according to different uses can be divided into ordinary and special roller

bearing roller . Common roller bearing in the normal section of the upper branch and lower branch roll , their role is to support the conveyor and materials ; special

The role of the Power Roller Conveyor of the transition guide , preventing side running belt and buffering . Groups of rollers are mounted on the conveyor . The basic requirements

roller group are: the use of reliable , rotary drag coefficient is small , low cost , with sufficient carrying capacity. Roll

Spacing should satisfy conveyor roller bearing capacity and sag two conditions . Due to excessive force required to encrypt roll , according to the actual needs identified by

the designer roller spacing.
   According roller belt speed and carrying capacity limits to choose . Conveyor roller set is an important component in the conveyor according to the role of the drive rollers

can be divided and redirecting rollers roll two categories. The role of the drive roller drive means is transmitted to the torque provided on the conveyor belt

; Redirecting roller comprises a conveyor belt at the end of the bend , increasing wrap angle of the drive roller guide rollers , tension rollers and the tensioning device for

the guide rollers. In general, the drive roller surface is covered with rubber or ceramic tube and the drive roller to increase the friction between the conveyor belt

Factor . Belt conveyor drive roller bearing capacity divided according to light, medium and heavy-duty three kinds , all of the roller surface adhesive surface . Redirecting

roller bearing capacity is also divided according to light, medium and heavy-duty three kinds , roller structure with the same bandwidth and with the same diameter of the drive

roller .

Frequently used conveyor idlers how to maintain it

Roller as a common accessory , the general use of non-stop , then the rollers frequently used technical maintenance of the use of what it ? Here we talk about for at this point . First, develop a baseline Turn conveyor tapered roller, friction roller baseline reflected in the normal operation, no visible

Errors, adequate lubrication conditions decibel . To develop a baseline of three ways: 1 , Comparative Law : If you have the same type of a plurality of tapered rollers, friction rollers, these Pallet conveyor bearings can be compared together . Using the same test method , or from the same perspective of each

A bearing . Analysis decibel intensity and sound quality. If there is no essential difference ( less than 8 db ) , we can set it on the basis of each roller decibel intensity . 2 , add the oil , when setting the base line : When adding oil when listening to the sound intensity , when the sound

Sound intensity decreased and then increased . At this time , do not add too much oil , and the set it to baseline . 3 History: observation tapered roller, friction roller decibel intensity recorded daily for 30 days and then compare the results recorded . If the decibel intensity change with little or no

Change ( less than 8 db ) , we can put this to the baseline , and observe the results for future comparison value . Second, set the schedule , such as observation and production , environmental results , the operating results of associated equipment is selected and set critical assessment of the mechanical system of the main factors . When the base

Base line was observed after the enactment tested once a month is necessary. For those who want to lubricate the high-decibel , frequency should be detected more frequently , so that it can be observed that the changes that may occur . If a tapered roller, friction roller is going to destroy the state ,

So lubricants only temporarily masked errors. However, the decibel intensity will soon be elevated to display an error exists. In some cases, this phenomenon is apparent within a few minutes , while others take several days. Third, lubrication detect if a tapered roller, friction roller decibel

Exceeds the base line 8 db , we believe that this needs to be lubricated bearings . When we realized that the bearings require lubrication , then know when to stop oiling will prevent excessive lubrication appears.

Conveyor features

    Conveyor has a long history of ancient China high drum water overturned cars and mentioning , is the modern scraper bucket elevators and drag chain conveyor prototype. Conveyor line is within the specified continuous transportation of materials and material handling machinery , also known as continuous conveyor . Conveyors can enter

Line horizontal, inclined conveyor , it can be composed of space transportation lines, transmission lines are usually fixed. roller chain conveyor conveying capacity is quite large, and especially long haul , but also in the transportation process while completing more entry process operation, so applications are particularly extensive.
    Conveyor features
Easy to change direction , the flexibility to change the direction of conveyance , the maximum time you can reach 180 degrees ;
    Conveyor, each unit is formed by the rollers 8 , each unit may be used alone , it can use a plurality of unit coupling , very easy to install ;
    Also retractable conveyor , a unit ratio of the longest and shortest state up to 5 times ;

The method of reducing transport costs and reasonable transportation

Reasonable cargo transport can reduce transportation costs. Reasonable main form of transportation has the following five categories:
1 Partition reasonable transportation Conveyor System and marketing
Partition sales reasonable transportation, logistics activities is the organization of certain goods to certain production areas fixed in some spending areas. According to the

distribution and marketing , and transportation conditions , on the basis of the balance production and sales , Mine conveyors according to the principle of near production in recent sales ,

the goods go at least

Mileage , organizing transport of goods . Its scope of application , mainly on a single species , size is simple, centralized , decentralized consumption or production of

scattered , consumer focused , transporting a large quantity of goods , such as coal , wood, cement , grain, pigs, mine construction materials or production techniques not very

Complex , shortage of raw materials is not very low value products , the implementation of this approach, strengthening the production, supply, transportation and marketing of

planning, eliminate too far, circuitous , convection unreasonable transportation, make full use of local resources , and promote the rational distribution of production reduce

logistics costs , saving the National Transportation force

, Has a very important significance.
Balance production and sales in the implementation of district transportation should be based on changing market conditions, flexibility. Especially in the current period of

economic reform , in order to implement an open , invigorating the economy , between regions , between sectors , strengthening the lateral economic ties , mutual cooperation and

self- supplies

Increasing the procurement of goods , some may be unreasonable shipping. Which in some inadequate supplies , shortage of goods in the case of each other, transfer the remaining

places , in order to develop production, market prosperity is inevitable.
(2) direct transport
Direct transport , is in the process of cargo transportation organization , across business, material storage areas or railway, transport transit links , the goods from the

place of origin or shipped directly to the sales office of departure to or users, in order to reduce intermediate links. The means of production , because of some bulky or heavy

goods

, Generally taken directly from the production factories supply consumer unit ( production and consumption ) , the implementation of direct transport , such as coal, steel,

building materials and so on. In the commercial sector , according to the different commodities, take a different shipping methods . Some simple product specifications can be

supplied directly to the three production plants

Wholesale level , large stores or users , across two wholesale sectors , such as paper, soap, etc. ; also some commodity specifications, color is more complex, can be supplied

to the wholesale production plant , and then from wholesale distribution to retail stores or users. As for the foreign trade sector , to take a more direct transport

, On the export of commodities directly implemented by the port of origin approach. In recent years , with the economic system reform, in circulation that " multi-channel,

little links ," since the grass-roots , shop direct purchase, increasing the scope of freedom of procurement , direct transport to gradually increase the proportion of its

To reduce logistics intermediate links , to create the conditions .
Three . " Four on the" Direct transport
"Four on" direct transportation refers to all commercial , supplies wholesale business, transporting goods in the organization process, the local production of goods arriving

from overseas or not brought into wholesale warehouse , to take direct approach, the direct distribution of goods to the city's primary wholesale, retail stores or users ,

reducing

Least one intermediate links. The specific practices are: ( 1 ) on the factory direct ; ( 2 ) on the station ( Terminal ) dial ; ( 3 ) on the Library Direct ; ( 4 ) on the

vehicle ( boat ) overload .
"Four on the" direct and direct transport are two different forms of transportation and reasonable , they are both different but related . Direct transport generally refers to

transport mileage distance, larger quantities , to the province ( region ) goods shipped outside ; " four on the" Direct transport generally refers to transport mileage closer ,

smaller quantities , in

Medium-sized city located handled wholesale dial transportation business. The two are complementary , they often intertwined . Such as in the implementation of direct transport

, while another organization " on the factory", " stood " dial , you can receive double money.
4 -pack truckload
Co-loaded vehicle transportation, also known as " partial shipments LTL transit vehicle to fight ." It is mainly suitable for commercial , supply and marketing and other

departments of cargo transportation . That rail freight logistics enterprises in the organization which , by the same consignor will be sent to the different varieties of the

same station , the same consignee LTL consignments from

With their own set of logistics enterprises in a vehicle to vehicle transportation way , consigning to the destination ; or the same in a different direction to the station 's

LTL focus group with a vehicle and transported to an appropriate station , and then transit of shipment. This is because , among the rail freight ,

There are two shipping method , one vehicle , one LTL, a big difference between the two tariffs . Loaded vehicle approaches taken together , can reduce the part of the

transportation costs, and labor- saving society .
5 . Improve the technical load capacity
Improve the technical load capacity , is to organize transport to improve transport efficiency reasonably important . On the one hand is to maximize the use of travel dwt ;

hand, is full use of the travel load capacity .

Transportation equipment classification and the classification of the introduction

Transportation equipment is in a certain line of material handling machinery continuous transport of materials , also known as pipelining . Transmission lines can be horizontal,

inclined and Incline Belt conveyor can also be composed space transmission lines , transmission lines are generally fixed. Conveyor conveying capacity , long distance

, Also in the transportation process while completing a number of process operations, so widely used.
Plate chain line : the chain plate towing plane transport workpieces to do sports, to achieve the purpose of the production process . A modular assembly line model, according to

the median worker process requirements set . Station is equipped with an electrical outlet , toolbox, feed box , so that the whole process to achieve delivery, there

Sequence .
Plug the pipeline : the chain drag Heat Exchanger tooling trolley , horizontal loop operation , the workpiece assembly .
Differential chain pipeline : the use of special aluminum alloy for rail , towing tooling plate with chain growth as the transmission medium . A modular assembly line model,

according to the median worker process requirements set . Station is equipped with foot switch, power outlet , station stopper , craft drawing board

, Lighting , etc., provided on line body lifting pan machine , lifting rotary table , so that the whole process to achieve automatic operation.

Buried scraper conveyor works

    Buried scraper conveyor transported in the horizontal plane , the material will be scraper chain in the direction of movement of the pressure and the materials own weight ,

and in the internal friction is generated between materials . The friction between the material layer also ensures a stable state, and sufficient

Material in the tank to overcome the movement of the outer friction generated , so that the entire material to form a continuous stream and is transported .
When buried portable conveyor in vertical lift , the material on the direction of movement by the scraper chain pressure , the material will produce the transverse direction

lateral pressure , thus forming internal friction of materials . At the same time as the horizontal section under continuous feed , lower material will have on

Upper material generates tractive force . This tractive force sufficient to overcome the friction and the material in the slot machine outside the friction generated by moving

its own weight and material , the material to form a continuous whole of the material stream is thus improved.
    Enclosure in a closed chain by moving the friction of the blade and the coal coal output continuously at run time the spiral conveyor coal buried in the solid-phase

connected to the traction chain scraper conveyor chute in a closed bulk material conveyor. Such a drag chain conveyor and the blade are buried on

Into the material , the blade section only accounts for part of the trough , the trough accounted for the majority of the material section . It horizontal, inclined or vertical

transportation of materials . Horizontal transport when the blade is flat strip used , the use of bulk materials buried scraper chain and bulk material layer on a cutting force

is greater than the groove wall

The principle of the bulk resistance , resulting in bulk with the blade moves forward , this time the movement of the material layer height and width ratio of the ratio in a

certain range, the material flow is stable.

Introduction belt conveyor

    Belt conveyor, Screw conveyor is more suitable for conveying bulk density less than 1.67 / t / cubic meter, easy to dig a powder, granular, small block of low- abrasive

materials and bags of materials , like coal, crushed stone, sand , cement, fertilizer, food and so on. Sent material temperature

Less than 60 ℃. Its captain and assembly forms can be determined according to user requirements , transmission can be electric drum can also be used with the drive rack drives.
    Belt Conveyor is diverse forms of use , which can be a single airport conveyor also be composed of multiple components or other transportation equipment horizontal or inclined

conveyor , to meet the different needs of the operating line layout .
Belt Conveyor basic model is : TD75 type conveyor , DTII type conveyor , QD80 type conveyor , DJ -type inclined conveyor , DY -type mobile conveyor .
    Common belt conveyor can be divided into: ordinary canvas core conveyor belt , high strength steel cord belt transmission machine, run under full proof belt conveyor ,

flame-type belt conveyor , two-speed dual op- belt conveyor , reversible mobile belt conveyor , belt conveyor and so cold .

Belt routine maintenance and periodic maintenance

Installing centerline is not straight . However, if the rack Telescopic belt conveyor rope vertical and horizontal level is not . Semi- hanging belt who woo wood horizontal spacing changes , or the word

wood into his inward tilting belt deviation , etc. are bit serious . This occurs , only the down regulation of horizontal distance down. Longitudinal onwards

Volt is generally not affect the deviation . Of course, the ups and downs too big, too powerful and easy belt surge deviation .
Tape joints are not straight . That belt buckle crooked nails or tape bandwidth is not cut at right angles with the belt tension by uneven . This joint operation run time to get

there , where the deviation occurs . When this happens, with cutting down Guppy positive , heavy nail .
Extendable conveyor roller centerline Centerline not straight with consultation , installed crooked . This is mainly because the rack is not properly installed . This occurs despite

acres to adjust roller bearings front and rear position , but the distance is limited, must be rack mounted crooked rework reloading . Head wave Jianduxiangzhong

Heart must be asked with a soft tail roller center line .

Belt conveyor technical advantages

The first is its reliable operation. Require continuous operation in many important production units, such as the transport of coal power plants , steel mills and cement

conveying bulk materials , as well as loading and unloading of ships in ports all adopts Telescoping conveyors . If the shutdown these occasions , the loss is enormous

. If necessary, take a class to a group of belt conveyor can work continuously . Conveyor low power consumption . As the material almost no relative movement of the conveyor

belt , not only the running resistance ( approximately scraper conveyor 1/3-1/5 ) , but also the wear and broken cargo were small ,

High productivity. These are conducive to lower production costs. Telescopic belt conveyor belt conveyor line adaptable and flexible . Line length according to need. Short as a few meters ,

length up to 10km or more. Can be installed in a small tunnel , ground transportation can also be set up in the confusion and danger

Region over . According to process requirements , can be very flexible belt from one or more points by the material can also be more or several sections to discharge . While

simultaneously at several points on the feeding conveyor ( such as the Coal bunker conveyor ) or along the length direction of the belt

Any point by uniformly feeding equipment to feed conveyor , the belt has become a major transport route . Coal stockpile conveyor can stockpile reclaimer roadway below , when

necessary , but also to the heap of different materials are mixed . Material from the conveyor can be simply

Unloading of the machine head , but also by moving plow unloader or unloading vehicle longitudinal direction of the belt at any point discharge .

Conveyor protection device selection and installation

The composition of the belt conveyor

Belt conveyor is a relatively common conveyors, briefly explain the type and characteristics of commonly used gravity conveyor belts and plastic belt two kinds . Rubber band for

working environment temperature -15 ~ 40 ° C between . Material temperature does not exceed 50 ° C. Inclination upward transport of Granules

12 ° ~ 24 °. Available for large transmission angle tread rubber band . Plastic belt with oil, acids, alkalis , etc., but the climate and poor adaptability , easy to slip and

aging. Bandwidth is the main technical parameters of industrial belt conveyor .
Of single drum ( tape on the drum wrap angle of 210 ° ~ 230 °), double drum ( wrap angle of 350 °) and multi- cylinder ( for power ) and so on. There trough roller , flat -

shaped roller , spherical roller, buffer roller . Trough roller ( 2 to 5 by the roller composition ) supporting bearing branches to lose

Send granular materials ; aligning roller to adjust the lateral position with , to avoid deviation ; buffer roller mounted in place by the material in order to reduce the impact

of material on the belt .

Food conveyor line maintenance 5 reciprocity

Which Food conveyor development is immeasurable. Food conveyor is convenient , but in order to protect our lives and property, or to be cautious strict accordance with the

production requirements to operate.
Transmission line equipment in the food or in the production line staff install conveyor equipment , often for some jobs often malfunction can not find the crux of it is not

understood how to troubleshoot and even delay the production losses to the enterprise . Below we talk about the food

Product conveying line at runtime , transmission lines belt deviation causes and treatment methods, and Gravity roller conveyor maintenance.
Food conveyor has long been widely used in coal, grain, flour mills and other industries in the conveyor , not only easy to manage but also can be transported in bulk (

lightweight ) of the material , but also to transport bags ( weight -based ) materials.
Food conveyor running in production which , slipping for many reasons , the following we talk often seen in the job as well as ways to deal with :
Method 1: Food conveying line belt load is too large , the load exceeds the capacity of the motor can , therefore slip. At this point should be to reduce the amount of

transported material transport conveyor itself or increase the loading capacity .
Method two : food conveyor line to start too fast and cause slipping. At this point should slow start or jog again and restart twice , it can overcome the slip phenomenon.
Method three: initial tension is too small. The reason is belt tension when leaving the drum is not enough, caused by belt slippage . At this point processing method is to

adjust the tensioning device , increase the initial tension .
Method four : It is not rotating roller bearing damage . May be due to the accumulation of too much dust or did not timely maintenance and replacement has been severely worn

parts and rotation is not flexible , resulting in increased resistance and slip.
Method five : is the drive roller and the conveyor belt is not caused by the friction between the skidding . Most likely cause of the conveyor belt with water or humid operating

environment . At this point in the drum should add a little rosin powder.

High temperature resistant conveyor working principle and introduces the main features

With the conveyor , pipeline and other transportation equipment development , transportation equipment manufacturing plant has started in popularity , it is undeniable that, to

some extent, conveying equipment to the manufacturer can indeed save a lot of manpower and material resources, it is beyond doubt the . However , it is undeniable

, And some special industries have begun to use transportation equipment, such as some high-temperature industries , but these industries use transportation equipment , it was

found that many of the transportation equipment industry than other short life a lot, which prompted a high industrial belt conveyor born.
High temperature resistant conveyor suitable for temperatures below 300 ℃ in the delivery of materials , is a transportation equipment, transport all kinds of powder, granular,

lumpy and mixtures of materials in mining, metallurgy, building materials, coal , chemicals , grain, pharmaceutical and other industries widely used.

discharge may also need to be made one o'clock feed , a little out of material , a little feeding, discharging multi-point , multi-point feed , a little out of materials such as

A variety of types . Long distance transportation available when connecting multiple conveyors transport .
High temperature resistant conveyor trough using rubber springs or steel springs support , relying on a fixed chute from two vibrating motors synchronous operation, the chute

produce linear vibration .

Conveyor heart - roller

Carrying idlers effect of technological innovation that is very subtle . Example is to increase the thickness of the wall , to look forward to improving roller wear life . This

method is not only sealing problems have not been solved , but also increases the moment of inertia of the roller and bearings were stuck over

This will lead to early failure of the tape severe wear and energy consumption, noise pollution and a variety of potential accidents.
screw conveyor as the "heart " of the Extendable conveyor is not a substitute bear " Tasks" , in order for the overall performance of roller can achieve a more desirable requirements ,

slowly change the traditional roller sealing structure , in order to reduce the weight of rotating parts , in

Traditional roller conducted on the basis of high technology processing and production , is already producing the best technology on the market of products .
Only by addressing the roller running work, watering, dust fudged the gap will be very easy to drill down into the labyrinth seal structure. Pollutants just to enter the first

maze, then it will certainly extend inward gangbusters , bearings will soon be stuck, thus making

Become idlers premature failure.
In order to ensure the operation of the conveyor belt is very reliable , the most important is that it can be more timely detection and exclusion failure may occur . To this end

the operator had to be ready to observe the work of transport , such as unusual will be processed promptly . Mechanical workers to

Regular inspections and checks of any circumstances or parts need to pay attention , which is very important.

On the introduction of large angle belt conveyor

Is inclined belt conveyor is a friction drive for continuous manner to transport materials machinery and equipment, it can be applied to the material conveying line at a certain

supply of material from the initial location to the destination location between the formation of a material discharge the delivery process .
Inclined Telescoping conveyors belt ribs is by the baseband , and the partition wall composed of baseband appearance with ordinary conveyor belt, but will be greater lateral stiffness ,

also wavy ribs , ugly plate divided into sections according to the different groups and T -, C -and TC type . T- apply the inclination β ≤ 50 ° field

Together , C-type for the angle β> 40 ° and the material better mobility of the occasion , TC type suitable angle β> 40 °, the viscosity of the material on the great

viscosity of the occasion.
Inclined belt conveyor wall is both universal Telescopic belt conveyor structure is very simple , more reliable operation , easy maintenance, etc. , more inclined conveyor , the structure

is very compact, occupying less in recent years in large lifting height , a large throughput of aspects of development, but also should

With more extensive.
Inclined belt conveyor is driven by a belt tensioning device , the central architecture and consists of roller conveyor as towing and carrying member , so as to continuously

conveyed into pieces scattered and fragmentary materials or goods .
