In Example it was determined that a 1400 HP wet grinding ball mill was required to grind 100 TPH of material with a Bond Work Index of 15 (guess what mineral type it is) from 80% passing ¼ inch to 80% passing 100 mesh in closed circuit. What is the size of an overflow discharge ball mill for this application?
