energy balance. Data from the three grinding circuits studied show that on average 77% of the electrical energy supplied to the grinding circuit is transmitted to the slurry, the grinding work accounts for 10%, 8% is lost through the drive system and about 5% of the energy is transmitted to the ambient air around the grinding mills. This
