Artificial intelligence applied to mill optimization

Grinding mills often pulverize hard ores and as a result, is subject to large forces that affect its wear, life, and safety. The grinding circuits often consists of sag (semi-autogenous grinding) mills, ball mills, pebble crushers, screens and hydro cyclones to produce the desired particle size distribution in the powdered ore.
