Energy balance data is related to mill temperature where the latter is believed to be a primary indicator of in-mill process dynamics [21, 12]. It is a known fact that the biggest part of energy introduced in a ball mill is converted into heat, with only about 3 - 5% of this energy being used to grind the ore to the required fineness.
