Conveyor use can be divided into several

1 , bulk material handling machinery ( such as: conveyor screw conveyor bucket elevator steep conveyor , etc.)
( 1 ) by a drive belt conveyor conveyor belt tensioning device composed of the central frame and roller conveyor as traction and bearing member , whereby continuous conveyor

into pieces scattered and fragmentary automated sorting machine materials or goods .
A friction drive conveyor transported materials in a continuous mechanical . Apply it, the material can be transported in a certain line, from the initial feed point to the

final discharge point between hot water heat exchanger the formation of a material transport processes . It can deliver a granular material can also be

For delivery into items . In addition to the purely material handling , but also can be used with various industrial production processes required in the process of cooperating

to form a rhythmic flow transport line . So the belt conveyor is widely used in modern industrial enterprise.
Underground tunnel in the mine , mine ground transportation systems , open pit and concentrator , the widely used conveyor . It is used for horizontal or inclined transportation

transport .
Universal conveyor from the conveyor belt, roller , roller and drive , brake , tension , bend , loading, unloading , cleaning and other device components.
① conveyor
There are two commonly used with rubber bands and plastic . Rubber band applied between the working environment temperature -15 ~ 40 ° C. Mass temperature does not exceed 50 °

C. Transported upward inclination of Granules 12 ° ~ 24 °. Delivery available for large angle tread rubber band . Plastic belt with oil, acids,

Bases , etc., but for the poor climatic adaptability , slippery and aging. Bandwidth is the main technical parameters of belt conveyors.
② roller
Of single drum ( tape wrap angle on the drum 210 ° ~ 230 °), double drum ( wrap angle of 350 °) and multi- cylinder ( for power ) and so on . There grooved rollers , flat -

shaped roller , spherical roller, roller buffer . Grooved roller ( 2 to 5 of the roller component ) support bearing branch

For conveying granular materials ; aligning roller to adjust the lateral position of the band , to avoid deviation ; buffer roller mounted in place by the material in order to

reduce the impact of the band 's material .
③ drum
Minute drive rollers and idler pulley . Drive rollers of the main power transmission member . Of single drum ( tape wrap angle on the drum 210 ° ~ 230 °), double drum ( wrap

angle of 350 °) and multi- cylinder ( for power ) and so on .
④ tensioning device
Its role is to enable the belt to achieve the necessary tension to prevent slipping on the drive roller, and to the conveyor belt between the deflection roller to ensure within

a predetermined range .
