Sep 18, 2022To calculate a ball mill's critical speed use the following equation: For the mill speed of 16.6 RPM, means that this ball is running at (16.6 ÷ 22.1) X 100 = 75 % of its critical speed. Bear in mind that feed material type, ball volume loading, ball charge gradation and liner types can also affect the grinding conditions as well.

Cement Grinding - Cement Plant Optimization
Grinding media contain balls of different sizes in designed proportions with large sizes in feed end and small sizes in discharge end. About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge where compensation for wear can be done by balls of one size only usually the largest size in the compartment.
