The diameter of the balls used in ball mills play a significant role in the improvement and optimization of the efficiency of the mill 4. The optimum rotation speed of a mill, which is the speed at which optimum size reduction takes place, is determined in terms of the percentage of the critical speed of the mill 8. The critical speed is

Ball Mill Parameter Selection Calculation Power . Aug 30 2019 22 rotation speed calculation of ball mill critical speed when the ball mill cylinder is rotated there is no relative slip between the grinding medium and the cylinder wall and it just starts to run in a state of rotation with the cylinder of the mill this instantaneous speed of the mill is as follows
Aug 20, 2011 The corresponding critical rotational speed, Nc in revolutions per unit time, is given by In this equation, r is the radius of the mill less that of the particle. It is found that the optimum speed is between one-half and three-quarters of the critical speed. Figure 2.28 illustrates conditions in a ball mill operating at the correct rate.
