Figure 1 shows the primary milling circuit, and Figure 2 the secondary milling
Read On18.9.3 Grinding Mill Control in Closed Circuit. The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.
Read OnPrimary & Secondary AG Autogenous Grinding. Primary autogenous mill feed is either primary crusher discharge or run of mine ore, containing material on each size of the screen analysis below the largest piece in the feed. It is subject to the large variations in size analysis normally found in primary crusher products or run of mine ore.
