Developments in iron ore comminution and classification technologies. A. Jankovic, in Iron Ore, 2015. 8.3.2.2. Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20

Get Priceenvironment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions: • The grinding of coarse particles; and, • The removal of the fine particles to make room for grind-ing more coarse particles in the ball mill. The overall efficiency of the ball mill circuit is therefore comprised of two efficiencies: that of the "ball mill

Get PriceThe critical speed (rpm) is given by: n C = 42.29/ √ d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers (although this depends upon feed input size - mills including a roller press are mostly single-chambered
