How to design a Ball Mill

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

Grinding Mill Power

If now ξ is the ratio of the power to drive the mill charged with balls and powder to the power to drive the same mill with a ball charge only, then: ξ = Wt. of ball charge x Wt. of powder charge/Wt of ball charge. If also it is assumed that the porosity of the ball charge and of the powder is 0.4 in each case, then:
