Screw conveyor

Spiral conveyor is a continuous conveying machinery that uses rotating spiral blades to move materials along a fixed housing groove in a directional manner, thereby conveying materials horizontally, obliquely, or vertically, commonly known as a "winch". Its core component is a rotating shaft with spiral blades, commonly referred to as a helical shaft. When the spiral shaft starts to rotate under the drive of the driving device, the frictional force generated between the blades and the material causes the material to be pushed forward, thereby achieving continuous conveying of the material.

The spiral conveyor is mainly composed of spiral blades (spiral body), casing, driving device and other components. Among them, the spiral machine body is composed of head bearings, tail bearings, suspension bearings, spiral, casing, cover plate and base, etc; The driving device consists of an electric motor, a reducer, a coupling, and a base.

Spiral conveyors are widely used in various sectors of the national economy, such as cement and coal ash mixers, grain industry, building materials industry, chemical industry, machinery manufacturing industry, and transportation industry. They are suitable for conveying various powdery, granular, and small block materials. The bulk materials they transport include grain products such as grains, beans, and flour, building materials such as cement, clay, and sand, chemicals such as salts, alkalis, fertilizers, as well as bulk commodities such as coal, coke, and ore.
