Screw conveyor

The screw conveyor is a machine that uses a motor to drive a spiral turn and move the material to achieve the purpose of conveying. In the form of conveying, it is divided into two types: a shaft screw conveyor and a shaftless screw conveyor. The outer shape is divided into a U-shaped screw conveyor and a tubular screw conveyor. Axial screw conveyors are suitable for non-stick dry powder materials and small granular materials (cement, fly ash, lime, grain, etc.), while shaftless screw conveyors are suitable for conveyors from viscous and entangled materials (sludge, Biomass, garbage, etc.).

product description

Technical performance and characteristics

Adaptable, easy to maintain
It has strong adaptability, small resistance, long life, convenient maintenance and safe operation.

Simple structure, easy to transport
It can be transported horizontally, obliquely or vertically. It has a simple structure, small cross-sectional area, good sealing and easy closed transportation.

working principle

The screw conveyor is a rotating spiral blade that transports the material and carries it by the screw conveyor, so that the force of the material not rotating together with the screw conveyor blade is the weight of the material itself and the friction resistance of the screw conveyor casing to the material, and the screw conveyor rotates. The spiral blade welded on the shaft has a solid surface type, a belt surface type, a blade surface type and the like according to different materials to be conveyed. The screw shaft of the screw conveyor has a thrust bearing at the end of the material moving direction to give the axial reaction force of the spiral with the material. When the length of the machine is long, the intermediate hanging bearing should be added.
