### Closed Circuit Grinding VS Open Circuit Grinding

Closed Circuit Grinding VS Open Circuit Grinding. The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required,...
