What is screw conveyor?

Screw conveyor is a kind of continuous conveying equipment widely used in metallurgy, building materials, chemical industry, grain and mechanical processing departments. It is mainly used for conveying all kinds of loose materials such as powder, granules and small blocks. This machine is not suitable for conveying special materials that are easy to deteriorate, sticky, caking or high temperature, afraid of pressure and corrosive. Screw conveyor can be divided into horizontal and inclined types according to the conveying angle.Based on the trough configuration, there are two types: U-shaped trough and pipe-type.
Screw conveyor generally consists of three main components: the conveyor body, the inlet and outlet ports, and the drive unit. The screw blades of screw conveyors come in three forms: solid screw surfaces, belt-type screw surfaces, and blade-type screw surfaces, among which the blade-type screw surface is relatively less commonly used. It is primarily employed for conveying materials with high viscosity and compressibility.
