Screw Conveyor

A screw conveyor is a continuous conveying machine that moves material by the rotation of a screw. It is suitable for conveying flour, grain, cement, fertilizer, ash, sand, gravel, coal powder and small lump coal. Because the effective flow area inside the machine is small, screw conveyors are not suitable for materials that spoil easily, are very sticky or tend to cake. They can be arranged horizontally or on an incline; if a change of conveying direction is required, this must be specified as a special order.
