The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product. Trommel Screens are attached to the end of grinding mills and scrubbers to perform a variety of screening functions. The trommel screen comprises the rubber lined steel frame and replaceable screening surface.

The purpose of the trommel screen is to classify the ball mill discharge, by size, into two separate streams. OPERATION. Ground ore slurry exits the ball mill over a trommel screen (Equipment Specifications). The trommel has a slotted screening surface, and material that is too large to pass through the trommel goes into the ball mill scats bunker.
