Mill capacity. The output of a coal mill is greatly influenced by the coal properties, namely, 1. Grindability (HGI) 2. Moisture. 3. Product fineness. The capacity of the mill varies somewhat directly in proportion to the HGI and inversely to fineness, as shown in Figure 13.15. There are three types of mill capacities as described below.

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
