Patent-family-91434719

The invention relates to a method for controlling a crushing plant 12. The plant can be designed for the secondary and tertiary crushing of rock with several circuits and control variables. The method is advantageous for the process monitoring of the plant 12 in that the expert system 10 can recognize the most common error states on the basis of the recorded, real operating data 18 in conjunction with the simulation 14. Suitable indicators can thus be identified in order to warn an operator at an early stage.
