### 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

Apr 01, 2013· 1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful. Because of the high magnetite concentration of the ore it was found that the actual density exceeded the required density,

Closed circuits return a certain amount of the ball millâ€™s output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times . Hydro-cyclones installed directly after the ball mill ensure only over-sized material is returned to the ball mill.
