The use of screw conveyor 

 Screw conveyor in wider use in the chemical plant, screw conveyor is mainly used to deliver powder, granular and small lump materials, such as coal, soda ash, recycled rubber powder, zinc oxide, calcium carbonate and a small lump coal, etc., screw conveyor is not appropriate to transport perishable, the viscous easy caking materials. 

 The continuous conveyor screw conveyor is a wide range of sectors of metallurgy, building materials, chemicals, food and machining applications. 

 Division, from the perspective of transportation of materials to the displacement direction of the screw conveyor is divided into two types of horizontal screw conveyor and a vertical screw conveyor is mainly used for conveying the level of the loose materials of all kinds of powder, granular and small block and vertical lift, the aircraft is not suitable for transportation of perishable and large viscosity, caking or high temperature, afraid of pressure, the larger corrosive materials.
