### Dynamic Modelling of Temperature in a Wet Ball Mill

2019-9-1 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.

More### Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
