Screw conveyor is a kind of conveying equipment that drives materials to move continuously through rotating screw blades, and it is suitable for conveying bulk materials such as powder, particles and small blocks (such as cement, grain, chemical raw materials, etc.) horizontally, obliquely or vertically for a short distance.

2. Main structure
Spiral shaft: the central shaft drives the spiral blade to rotate, and the material is mostly carbon steel or stainless steel.

Spiral blades: divided into solid type (conveying dry powder), belt type (viscous material) and blade type (mixing or heating material).

Driving device: motor+reducer, which provides power and controls the speed.

Feed inlet and discharge outlet: multiple feed points or discharge outlets can be designed to flexibly adapt to process requirements.

Tank body/pipe body: U-shaped tank (open conveying) or round pipe (sealed and dustproof).

Support structure: bearing seat, hanger, etc., to ensure the stability of operation.
