1.2 DESCRIPTION. Screw conveyors consist of revolving shafts with a continuous or broken spiral fighting that operates insides a casing. This is powered by an electric motor and suitable gearing, the screw conveyor usually operates in one direction only to move fine bulk material such as meal, seed, coal, etc from one point to another point.
