The invention relates to a drive control method for a vertical mill (10) having a grinding plate (12) that can be rotated about the vertical axis, said grinding plate (12) being drivable by means of a drive train that comprises at least one electric motor (14) and a gearing (16), a measurement value curve resulting from acquired torque or rotational speed measurement values (28) being monitored for the occurrence of a predetermined pattern in the measurement value curve. If a pattern is recognized in the measurement value curve, the rotational speed of the grinding plate (12) is increased or decreased automatically by an adaptive value (38) that is or can be predetermined. The invention further relates to a drive system operating according to the method. |
