When a material conveying is required over a short distance either horizontally, vertically or at some angle, screw conveyor is the mostly adapted equipment in the industry. It consists of a screwed shaft (Auger) rotating in a pipe for vertical lifting and in a U-shaped trough for horizontal conveying. The screw is mounted on dust protected anti- friction bearings. The screw body is provided with the dump-hopper for intake of materials and an outlet for discharging.
