How to Calculate Grinding Media in Ball Mill? Generally, steel balls must not fill more than 35% of the ball mill. The size selection of grinding balls can be calculated using the following formula: Dm <= 6 (log dk) * d^0.5. Here, Dm = the diameter in mm of a single ball. d = the diameter in mm of the biggest ore piece ore in the mill.
When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a …
