Abstract

The invention relates to a multi-stage grinding system and a method for controlling and/or regulating a multi-stage grinding system (2), each stage (A, B, C) comprising a grinding device (4A, 4B, 4C) for grinding a substance (S), a separating device (6A, 6C, 6D) for classifying the ground substance (S) and a separator (12A, 12B, 12C), having the following steps: a) at least one first parameter characteristic for the operation of the grinding system (2) and one second parameter are determined, b) the derivative of the first parameter with respect to the second parameter is determined, c) the sign of the derivative is determined, d) the grinding system (2) is controlled and/or regulated depending on the sign of the derivative.
