Abstract

The invention relates to a two-stage grinding plant and to a method for control and/or adjustment of a two-stage grinding plant (2), wherein a first stage (A) comprises a SAG mill (4) for grinding a material (S) and a classifier (8) for classifying the ground material (S) and a second stage (B) comprises a pebble mill (14), a hydrocylone (16) and a classifier (26), comprising the following steps: a) at least one first parameter characteristic for the operation of the grinding plant (2) and a second parameter are determined, b) the derivation of the first parameter is determined after the second parameter, c) the sign of the derivation is determined, d) the grinding plant (2) controlled and/or regulated as a function of the sign of the derivation
