It is possible to make an approximate calculation of the capacity of a ball mill by means of the equation: N = (0.104 D 3 L ρ b.ap ϕ 0.88 + 0.1 L n) 1 η 1 η 2. where ρ b.ap is the apparent density of the balls; l is the degree of filling of the mill by balls; n is revolutions per minute; ...

Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments.

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

This size batch will fill one of the empty Skylighter ball mill jars about 1/4 full, which is the optimum material load to be milled. Note: These amounts can be multiplied by 5 for use in larger, one-gallon ball mill jars if you have a mill that size. Weighing the Chemicals
