It is applied to convey loose materials such as powder, granular and small piece material, such as clay powder, pulverized coal, cement, sand, grain, small piece of coal, cobble, and cast iron filings, etc.

Working principle:

By adopting sliding bearing, dustproof sealed device and slide block, that make screw conveyor easy to install and maintain. When the screw shaft rotates, rotary spiral vane pushes materials continuously moving forward in closed housing.


1. Large handling capacity, safe and reliable.

2. Strong adaptability, convenient installation and maintenance, long service life.

3. Small volume, high rotate speed in order to ensure rapid and uniform transport.
