Mill Critical Speed Calculation - Mineral Processing & Metallurgy

Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the

Three Common Problems and Solutions In Ball Milling

The water amount in ball mill cylinder is an important index in ball milling process. It reflects the carrying energy of particle materials in ball mill. Therefore, the water amount through ball mill cylinder is corresponding with the material throughput of ball mill, which should be controlled in a suitable limit.
