The screw conveyor uses the rotation of the screw body to transport materials. It is suitable for horizontal and slightly inclined (<20°) continuous conveying of powdered and granular materials, such as cement, flour, fertilizer, coal powder, grain, ore, feed, pulp, sugar, etc. Its working environment temperature is -20~+40℃, and the conveying material temperature is -20~+80℃. The spiral blades are of two types: solid spiral surface and belt spiral surface. The belt spiral surface is suitable for conveying medium viscosity materials.
