Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.

So far, the biggest mill for lignite coal grinding will be delivered to Cemindo's Bayah plant in Indonesia. This MPS 4500 BK has been ordered for grinding lignite with a maximum moisture of 37% and it is able to produce a throughput rate of minimum 100 t/h at a residue of 15% R0.09 mm. The installed power for the mill main drive is 1300 kW.
