The large angle screw conveyor uses rotating spiral blades to push materials and transport them on the screw conveyor. The force that prevents the material from rotating together with the blades of the screw conveyor is the weight of the material itself and the frictional resistance of the screw conveyor housing to the material.

Structural characteristics of large angle spiral conveyor:

Spiral blades are welded onto the rotating shaft of a large angle spiral conveyor, and the blade surface types include solid surface type, belt surface type, blade surface type, etc. depending on the conveyed material. The spiral shaft of the large angle spiral conveyor has a thrust bearing at the end of the material movement direction to provide axial reaction force to the spiral along with the material. When the machine is long, an intermediate suspension bearing should be added.

The rotation direction of the rotating shaft of a large inclination angle screw conveyor determines the direction of material transportation, but generally, the design of the rotating blades of an inclination angle screw conveyor is based on single item transportation. When conveying in reverse, it will greatly reduce the service life of the conveyor.

The large inclination angle screw conveyor is a pipe type screw conveyor used for inclined conveying. The driving device adopts a gear reducer, which has high torque, low noise, no oil leakage, long service life, and the conveying shell adopts high-quality seamless pipes and flange connections.

The large angle spiral conveyor is widely used in various industries, such as building materials, chemical industry, power, metallurgy, coal, grain and other industries. It is suitable for horizontal or inclined transportation of powdery, granular and small block materials, such as coal mines, ash, slag, cement, grain, etc., with material temperature less than 200 ℃. The role of screw conveyors in concrete mixing plants has been greatly demonstrated.
