Abstract (en)
[origin: WO2010015564A1] The roller mill according to the invention comprises a grinding table (10), at least one grinding roller (11, 12) and at least two motors (drives) (13, 14) with stator and rotor windings for driving the roller mill and is equipped with at least one control device (20, 21) for regulating the motor torque of at least one drive. The control device is connected to the rotor winding (13a, 14a) of at least one drive for the purposes of influencing the rotor current. Further protected is a method for size reduction of ground material using such a roller mill.
