  • High recirculating loads in Ball Mill Circuits Grinding

    Apr 4, 2018 Why do ball mills have such high circulating loads?The ball mill grinds. The cyclones separate. But the pump neither grinds nor separates. So what is the purpose of having such a big pump to maintain high circulating loads in our grinding circuit?A recent grinding bulletin addresses this question f.
