The grinding table – and thus the grinding rollers – of the QMR² mill are set in motion by a motor with a gear unit. The rotating grinding rollers are pressed onto the bed of material by means of a hydraulic cylinder. As the grinding table rotates faster than the grinding rollers, it presses the material under the roller.
