2007-2-12 Screw conveyors may be grouped, broadly, into two categories, the U-shaped trough type conveyor and the fully enclosed conveyor incorporating a tubular casing. Screw conveyors with U-shaped trough type casings are widely used in industry, their operation being restricted to low angles of elevation, low speeds and low fill ratios.
