a roller mill or ball mill with a diameter of 3.98 m operating at a net energy loss of 19.5% to reduce a particle with sphericity of 1 from size of 3.98 X10^-3 m to 199.9 X10^-6 m. Calculate the percentage load volume to operate at 70% of critical speed. The mill cannot be operating at more than 1.31m^3 load volume at any given time
Percentage load volume to operate can be calculated by:
