The influence of mill speed and pulp density on the grinding

mill with a 30 mm graded ball charge and a 30% filling degree. The mill discharge pulp density was increased from 68.8% to 75.9% solids. The data is summarized in Table III. The example in Table III illustrates that the density has a large influence on the grinding efficiency. In this case, the optimum %<75 µis in the region of 73.4% or 1.989 kg/l
