Screw conveyor design requirements

Screw conveyor based design and select the required basic data as follows:
(A) the type of material to be transported and conditions
Experience has shown that the key to success conveyor design is about understanding the properties of materials being transported. In addition, the material is transported to

understand without rolling and shearing effect of tending to the screw conveyor is important, because it is easier to scroll difficult to cut than the material roll or cut

Material easier to transport. Familiar with and understand the flow of materials and rolling the impact of changes on the gravity skatewheel conveyor design is also very important. The

following properties of the material weakness to fully understand.
The type of material being transported, characteristics and temperature; material is dry or wet, corrosive no, block or adhesive properties, and other features;
The bulk density of the material being transported;
The material is transported largest block size, the percentage of the total volume bulk materials, the smallest material particle size. If possible, preferably with sieve

analysis results;
The abrasive material that can be used to represent the Mohs hardness;
Wash material off of mobility and its horns.
(2) requires the ability to transport OBJECTS
The ability of transportation of materials used t / to represent its normal and peak throughput.
(3) the delivery of materials from
The total length of the conveyor requires that the conveyor into and out of the spacing between the mouth again. If the incline conveyor system, to give the horizontal and

vertical distances and inclination.
(4) Conveyor Equipment
In order to choose a PC that meets the requirements of operation and installation of conveyors need to provide the following information;
Feeding method, the number and location of feed points;
The location of the discharge point;
Conveyor Application: transportation, upgrading, mixed, etc.;
Conveyor segment length (provided by the manufacturer segmented conveyor standard lengths and special lengths consisting of segmented total length);
Conveyor diameter and type of the spiral blade;
Some parts conveyor requires special materials;
The spiral trough of the type;
Require special suspension bearing frame, bearings, coupling shaft;
The type of the drive motor or the gear required layout.
(5) Operating conditions
Screw installed indoors or outdoors; ambient temperature range; batch or continuous operation; operation hours of a day.
