ABSTRACT:
The invention relates to a method and a grinding plant for reduction of brittle material for grinding, in which material which has undergone primary reduction from a first grinding stage is delivered as fresh material to the second mill of a second grinding stage and finished product is removed from this second grinding stage, and in which the quantity of feed material of this second mill is kept constant when the quantity of finished product alters by altering the quantity of fresh material. This first grinding stage contains an air separator from which the fines are fed as fresh material to the second mill. In the event of alteration in the quantity of fresh material for the second grinding stage the quantity is kept constant by corresponding alteration of the fineness of separation of the separator of the first grinding stage. In this way a reliable and sensitive adaptation of the total throughput quantity of the second mill is achieved by relatively simple means when the finished product removed from the second grinding stage alters.
