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.
