- design calculation for raw mill and coal mill

Mill HP is a maximum hp for a given mill when 45 to 55 percent of its internal volume is filled with grinding media. Mill HP is proportional to the effective grinding length of the mill. . Mill HP is proportional to the 2.6 power* of the internal mill diameter (inside shell liners) provided the percentage of critical speed is the same.
