 — Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

The first-stage closed-circuit grinding and grading process consists of a grate ball mill and spiral classifier. The second-stage closed-circuit grinding and grading process consists of an overflow ball mill and hydro cyclone. ... 5 ton per hour copper ore process plants; ... 20tph Rock Gold Processing Plant Provided to DRC Customer;
