## Calculation Of Ball Mill Critical Speed

Mill critical speed calculation. 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.

## Mill Critical Speed Calculation

Oct 15, 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.
