China Boyang Screw Conveyor Is Used for Conveying Materials in Factory

Shaft screw conveyor is suitable for non-viscous dry powder materials and small particle materials (such as: cement, fly ash, lime, grain, etc.) while shaft screw conveyor is suitable for viscous and easily wound materials.(for example, sludge, biomass, garbage, etc.) the working principle of screw conveyor is that the rotating screw blade pushes the material to carry out the screw conveyor transmission. The force that makes the material not rotate with the screw conveyor blade is the weight of the material and the friction resistance of the screw conveyor shell to the material.The spiral blade welded on the rotary shaft of the screw conveyor, the surface type of the blade has the solid surface type, the belt surface type, the blade surface type and so on according to the different transportation materials.The spiral shaft of the screw conveyor has thrust bearing at the end of the direction of material movement to give axial reaction force to the screw with the material. If the length is longer, the intermediate hanging bearing should be added.
(1) screw conveyor is widely used in chemical industry, building materials, food and other sectors of a conveying equipment, mainly used for conveying powder, particle and small block materials.It is not suitable for transporting perishable, viscous and caking materials.
(2) the ambient temperature of screw conveyor is -20~50ºC;Inclination Angle of conveyor beta ≤20°;The conveying length is generally less than 40m, and the maximum length is less than 70m.
(3) compared with other conveying equipment, spiral conveying has the advantages of simple structure, small cross section size, good sealing performance, intermediate multi-point loading and unloading, safe and convenient operation and low manufacturing cost.Its disadvantages are more serious wear and tear parts, lower throughput, large consumption of power and materials in the transport process is easy to be broken.
