Overview

1)Brief introduction of screw conveyor

Screw conveyors or auger conveyors usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process.

2) Features of screw conveyor

1. Wide range of bulk materials can be handled, including powder, granular and block materials.

2. High transportation efficiency.

3. Reliable electrical device and mechanical safety device.

4. Flexible installation and maintenance.

5. Construction available in carbon steel, stainless steel.

6. Engineered and manufactured to meet specific customer requirements.

3)Working principle ofscrew conveyor

The material feed into the casing and screw flight was hold back by the frication resistance acted on the wall of casing during running, the screw flight push the material and make the material do axial movement, simultaneity the clockwise and counterclockwise fight act as mixer. The material can be discharged at the proper outlet at the bottom of casing or transport out at the end of chute. Conveyor with simple construction, be able to feed and discharge in many position, it is easy to operate, have good seal capability and environmental friendly.
