The fineness of the processed material depends on the time the material stays in the grinding chamber ("dwell" time). Dwell time is controlled by the pumping rate. The slower the pumping rate, the longer the dwell time and the finer the grind. The grinding media used in continuous grinding mills range in size from 2mm to 10mm in diameter.

Ball mills are further characterized by the major differences in the sizes of grinding jars and what ball sizes are readily available. Retsch can supply ball mills with jar capacities ranging from 1.5 ml up to 150 l, and balls are available in sizes ranging from 0.1 mm to 40 mm, see Figure 2.

In comparing wet and dry open-circuit ball milling, wet grinding gave 39 percent more capacity and 26 percent more efficiency. A small ball volume was not satisfactory in the overflow type of dry mill because too much ore built up in the mill. When building up the ore was prevented by simulating the low pulp-level mill, the small ball …
