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 singlestage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required, but it can be ...

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

The capacities of these types of classifiers cover a wide range. Generally, highercapacity machines have a poorer sharpness of cut. Typical highcapacity industrial units are the cone classifier (often built into some types of mills) and the cyclone. The feed is given a high tangential velocity and is introduced near to the top of the unit.
