How Sizers work. Sizers use an electric motor to drive the gear reducer, which is mounted directly to the roll shaft. The motor and reducer are protected via a fluid coupling fitted with a thermal element and underspeed sensors to eliminate the risk of shock loads or stall events transferring through to the drive components.

How Single Roll Crushers Work. A Single Roll Crusher is made up of a toothed roll assembly, which crushes the incoming feed material against a crushing plate. The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 6:1 ratio of reduction while producing a considerably lower percentage of fines.
