Trommel screen
General Description:
The trommel screen provides a simple, efficient and economical solution to upgrade a wide rang of material, and optimize the subsequent process steps of recovery. This method of screening helps not only to reduce manual operation and investment, also increase product grade, while allows rapid and large volume processing.

Trommel screens are constructed of high quality material, designed for high performance, high production rates, lower operating costs and lower maintenance.  
Working principle:
From the storage hopper, raw material is fed into the drum, and lifted up by the rotation, in the meantime washed by the flushing water as it falls back down. This action is repeated with each revolution along the wall of drum screen. The finer ore passes through the screen while the bigger ore tumbles towards the eventual exit at the backside of the drum.
The fine size mineral ore is then passed to the downstream process equipment, which can be in various forms, such as centrifugal Concentrator, spiral chutes, jig machines etc.
