Crushing Efficiency Factors - Mineral Processing Metallurgy

12.07.2016  Toward the foregoing goal, engineers investigated the energy efficiency of crushing for less than ideal cases. In the first experiment they studied the effect of factors such as using a deep bed of particles, a situation usually present in a ball mill. The same type of slow crushing experiment described above was performed, but with a bed five or six particles deep instead of a single layer ...

The energy efficiency of ball milling in comminution ...

01.11.2002  In his 1986 paper, Schoenert provided a definition of process efficiency based on single-particle crushing data, namely, relating energy consumption in the ball mill to that consumed in single-particle crushing to yield the same particle size distribution as the mill product. In this case, if the energy consumption in the mill is taken as 28 kWh/t, Schoenert showed that process efficiency should be between 10% and 20%. Schoenert suggested as alternative definition of process efficiency ...
