Sep 01, 2019 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.
The control loop will attempt to add water to cyclone 1 sump to achieve a particle size of 15%+ 300 m. if the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. with the same water addition to sump 1 the particle size of cyclone 1 overflow will increase. this will decrease the ratio, and.
