For example, the D:L ratio for 32 ft dia. mills decreased from 3.00:1 to 2.17:1 over 35 years until the advent of 36 ft dia. mills in 1973. The D:L ratio for 36 ft dia. mills decreased from 2.53:1 to 2.06:1 over 23 years until the first 38 ft dia. mill was purchased in 1996. The 38 ft dia. mills are 1.87:1, with special cases at Freeport (2.08:1)

22.05.2019But too high a ball ratio is unhelpful. Because the amount of charge is reduced when the filling factor is constant, it is bound to reduce the productivity of the set, and sometimes reduce the alloy properties (Figure 8-2). The ball ratio is usually selected from 2:1 to 5:1. In some cases, a large ball-to-batch ratio is used. For example, a wet

Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls
