    The mill power draw was extensively studied by Morrell [13,21].His basic assumptions were similar to that of Austin. In addition to computing the power required for a mill, Morrell considered the individual power requirements for the cylindrical section and the two conical sections at either end of mill as the net power.The gross power was then the sum of the no load power and the net power.FM 306: SIZE REDUCTION AND SIEVING,FM 306: SIZE REDUCTION AND SIEVING OBJECTIVE •To grind the given limestone material to a smaller size using a ball mill and to obtain the size distribution of the initial and the final mixture by sieving. •To estimate the energy required for the grinding operation. •To analyze the results using the available theories.
