Trommel screen  for mine are used to separate materials into various sizes for further processing. Or for end use. Depending on our need. The material is separated by passing it through a vibrating "screen box" which has a number of different sized screens, or meshes, which the material falls through like a sieve, the material falls onto attached conveyors which stock pile the end products. The end products can then be used in the building and construction industries.  

Working Principle 

Trommel screens have a rotating drum with screen panels around the diameter of the drum and is on a shall angle. The feed material always sits at the bottom of the drum and as it rotates, always comes into contact with clean screen. The oversize travels to the end of the drum as it does not pass through the screen, while the undersize passes through the screen into a launder below.

Features:

1.It is suitable to separate various materials included poor quality of coal, coal slime.
2.It do not require special facility and suitable for various material feeding methods.
3. It has higher efficiency by the installation of comb shape screen structure.
4. Cylindrical shape of screen provided larger surface area which has higher possibility of materials to contact with the screen mesh; therefore, it has higher capacity and more effective.
5.It is a energy saving equipment.
6.The equipment is fully sealed with a cover to minimize the suspension of fine material in the air during the operation, able to avoid working environment pollution.
7.Since it is covered, less noise pollution during the operation.
8. It is durable and low maintenance cost.
9.The checking and the maintenance are easily to process through opening on the cover
