Wet grinding in closed circuit - INFINITY FOR CEMENT EQUIPMENT
A tube mill operating in open circuit with an output of 41.5 t/h (dry substance), was connected to a DSM Screen for grinding in closed circuit. The increase in mill capacity was 59 t/h, thus 40 %. Mill power con sumption was the same as in open circuit grinding; the pump operation required an …
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,...
Wet Grinding VS Dry Ball Mill Grinding
With that charge, closed-circuit work would be expected to develop the same type of circulating load, whether wet or dry. In wet grinding the heavy ore charge in the mill would give a closed-circuit product with the minimum amount of coarse particles, but in grinding the advantage would be in favor of the small ore charge.
