Trough Screw Conveyors

Trough Screw Conveyors


Trough screw conveyor usually uses a rotating helical screw blade to convey liquid or powder materials. The screw blade usually into a trough type tube. LS trough screw conveyor is widely used to convey powdery, granular and bulk materials in chemical, construction, food industries, etc.
Trough Screw Conveyors

Working Principle

The screw blade of the trough screw conveyor pushes and makes the material take axial movement. The material can be discharged at the proper outlet at the bottom of casing or transport out at the end of chute. With simple construction, screw conveyor is able to feed and discharge in many positions. Easy to operate and environmental friendly, it also has a good sealed capability.


Trough Screw Conveyors 1.Mild steel and stainless steel structure: Construction available in mild steel and stainless steel so trough screw machine can widely used for all kinds of material.
Trough Screw Conveyors 2.Seal cover device:Trough screw feeder with totally-enclosed structure without causing any environmental pollution.
Trough Screw Conveyors 3.Multiple inlets and outlets:With multiple inlets and outlets, trough screw feeder can mix material and unload material at any points.
Trough Screw Conveyors 4.Simple and independent components:With simple structure so trough screw machine is easy to assemble and replace of component parts.
Trough Screw Conveyors 5.Gear motor with lower power consumption: Easy maintenance and low operating cost.
Trough Screw Conveyors 6.Single or combination of multiple screw equipment operation:With flexible connection structure, screw equipment could be integrated with each other to meet the particular site requirements.
