Abstract
The invention relates to a process for regulating a grinding installation using four automatic control systems, of which one control system keeps the material level of the storage silo for the ground material constant by altering the grinding force of the roller mill. In this way, the mill throughput is altered in the event of variations in consumption in such a way that the differential mill pressure and hence the quality of the end product are kept constant.
