EXPLORING THE EFFECT OF ENERGY RECOVERY POTENTIAL

the average portion of energy input into ball mill grinding lost to the environment which in this case is 30% or 681 kW. Using mill make-up water (16C) as the cold source and the average slurry temperature (34.4C) as the hot source, the energy capture potential efficiency is estimated to be defined by the Carnot efficiency.
