Coal gangue screening trommel screen

trommel screen

A shaftless trommel is a special trommel that does not have a traditional shaft. Compared with the shafted trommel screen, it has higher efficiency, lower energy consumption and simpler structure. Shaftless trommel screens are usually used to screen light materials such as pulverized coal, granular minerals and granular chemical raw materials.

The working principle of the shaftless trommel screen is based on the principle of dynamics. The material enters the shaftless drum, and then is driven by the rotating drum to generate its own centrifugal force, so that smaller particles and powder are separated on the surface of the drum.

Coal gangue particle size grading screen Shaftless drum sieve During operation, particles and powders rotate in the drum, smaller particles form dispersed agglomerates on the drum surface, and larger particles form accumulations inside the drum. Since the shaftless drum has no traditional shaft, it saves energy and maintains efficient screening throughout the screening process.
