The determination of the specific energy depends among others on the mode of grinding operation. For a grinding process in a circulating mode (multipasses), the specific energy can be determined as follows: (1) SE = ∫ 0 t N τ − N 0 d τ m P Where m P is the mass of the solid product, N(τ) is the power at the time τ and N 0 is the noload power. If the grinding media wear is significant ...
