further reduced in size. Water is added to the ball mill, in which a slurry that usually contains from about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit with screens that size the ore and cyclones that sort the ore by size and density.
We offer them with either a hammer mill or a ball mill. Our 4-5 tph system comes with a ball mill only. The hammer mill version of our turn-key ore processors is less initial cost, but higher maintenance cost ($10-15/ton, plus down time). It will produce ground material with 70% passing a 30 mesh screen and 50% passing a 50 mesh screen.

The estimate utilized C$0.15 per kWh for energy cost, C$1050 per tonne for the cost of steel media, a wear rate of 6000 h for HPGR roll tires, 72 g/kWh for SAG mill media and 52 g/kWh for Ball mill media. As one would expect, both HPGR circuits presented a significant reduction in OPEX when compared to the SABC option.
