How Does Trommel Screen Work?

Materials are sent into the drum by the hopper, they are lifted up by the rotation and aerated as they fall back down.  This action is repeated with each revolution along the length of the drum.  The finer materials pass through the screen openings while the larger materials tumble towards their eventual exit at the rear of the drum.

Trommel Screen

Trommel screen working principle:
Materials are sent to the trommel screen drum and lifted up by the rotation and aerated as they fall back down. This action is repeated with each rotation along the length of the drum. The smaller material passes through the screen mesh while the larger material moves towards its exit at the rear of the drum. The trommel screen can be produce with one single screen mesh, two meshes, or three meshes according to the needs. There is cover outside to protect the equipment from dust.
