  • TECHNICAL NOTES 8 GRINDING R. P. King

    Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power

  • AUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT

    The unit power consumption shown in Table 2 is to grind the material to pass 3175 microns (trommel opening that was used). Typically, a commercial scale plant would grind this material to pass 6350 microns. The average specific power consumption (power at mill pinion shaft) for the AG tests was 10.73 kWh/mt, compared with 12.46 kWh/mt for the
