Critical Speed The Critical Speed for a grinding mill is defined as the rotational speed where The basic formula for this is the Bond formula Ball Mills The final stages of comminution are performed in tumbling mills using steel balls as . contributions to the modelling of the.
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 crosssection 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
