Energy Efficiency Analysis of Copper Ore Ball Mill Drive ...

23/03/2021  In Poland, the annual electric energy consumption from copper ore processing plants is approximately 2.5 TWh [8]. Primary ore comminution is performed with jaw and hammer crushers. Ore is then transferred to ball mills, in which it is first subjected to coarse grinding, and in the second phase (i.e., fine grinding) it is treated with grinding bodies (rods or cylpebs), which are introduced ...

01/11/2002  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, namely one that is based on the energy consumed in interparticle crushing (confined bed breakage). Using a reasonable figure for the energy consumption in a ball mill
