2 Design features of MPS mills for coal grinding. Depending on the material to be ground, throughput rates of 5-200 t/h can be achieved in a fineness range between 1% R0.063 mm and 25% R0.090 mm.
Raw coal (sometimes pre-treated) is fed into the centre of the grinding table. The grinding table rotates which causes the coal to move towards the outer periphery of the grinding table. The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring (retention ring).
