What is screw conveyor?

The screw conveyor is a kind of machine that uses the motor to drive the screw to rotate and push the material to achieve the purpose of conveying. It can be transported horizontally, inclined or vertically. Screw conveyors are mainly used to transport various powdery, granular and small block materials, such as cement, fly ash, lime, ore, sand and other building materials, salts, fertilizers and other chemicals, as well as coal and coke , ore and other bulk cargo.

Why choose screw conveyor?

1.Screw conveyors can be divided into shaft screw conveyors and shaftless screw conveyors in terms of conveying form, and can be divided into U-shaped screw conveyors and tubular screw conveyors in terms of appearance. Shaft screw conveyors are suitable for non-viscous dry powder materials and small particle materials, while shaftless screw conveyors are suitable for conveying viscous and easily entangled materials.

2. Screw conveyors can realize sealed transportation, which is conducive to the transportation of materials that are easy to fly, hot and smelly, and can reduce environmental pollution.

3. Screw conveyors can be conveyed in reverse, and a conveyor can also convey materials in two directions at the same time, that is, to the center or away from the center.
