When charging a grinding mill, the standard practice is to dump tons of balls into the mill at once and replace them somewhere between once a shift and once a week. It's an inefficient practice that wastes energy, impacts product particle size distribution and risks breakage of mill linings and grinding media.

Dry volume of total materials is equivalent to 1.54 times the volume of wet concrete. Hence let us take the quantity of cement mortar as 1.54 m 3. Quantity of cement. The formula to calculate the volume of cement is as follows: (1.54×1)/(1+1.5+3)=0.28 m^3. Since the cement is available in bags, volume of 1 cement bag is 0.0347 m 3.
