Oct 15 2015 The mill was rotated at 63 of the critical speed The position of the balls at the end of five revolutions is shown in Figure 2 It is seen that using a low coefficient of friction at the walls balls tend to flow down the surface of the charge and a toe begins to form As the friction at the wall increases cataracting motion is observed The first problem will ball mills is that we cannot see what is occurring in the mill The other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results In ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time mill speed see Graph 2 as the curves are mostly overlapping Density These tests were done with a 082 x 1 m grate discharge mill with a 30 mm graded ball charge and a 30 filling degree The mill discharge pulp density was increased from 688 to 759 solids The data is summarized in Table III
