Loss in efficiency can also be overcome by increasing the speed or the diameter of the screw conveyor. Additional horsepower ...

What Factors that Affect the Screw Conveyor Conveying ...

04/12/2015· The factors are listed as follows: 1.The material has great viscosity and is easy to agglomerate. The viscous material is easy to stick on the screw blade and the inner wall of the screw conveyor, which will increase the resistance in the process of conveying, and directly affect the production efficiency. 2.The diameter size of the screw pipe.

Screw Conveyor - an overview | ScienceDirect Topics

Screw conveyors are used to convey bulk material from almost any position (vertical, horizontal, or at an incline) and are one of the most reliable methods of conveyance. The screw conveyor is composed of a pipe with a welded steel strip that is formed into a continuous helix. The helix is referred to as the flighting. The distance along the pipe from one point on the flighting to the next ...
