Figure 4. Typical cement grinding mill A closed circuit consists of three main parts: the ball mill itself, the elevator lifting the mill product to the separator and the separator returning the oversize material to the mill as reject. The separator splits the final (fine) product out of the system. 3. Control Problems and Systems
