Determines the effective mill inside diameter of a given set of "top hat" lifters for use in mill volume and critical speed calculations. Calculates the cross sectional area of the "cone" portion of the lifter and estimates a corresponding mill diameter compensation for that cone. No radial component to the liner shapes is assumed.

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.
