    SAG and ball mills have grown in size and there are now many operational mills in the range of 28–40 feet in diameter with installed powers ranging between 8–20 MW. The very high capacity of these mills and the common use of variable speed drives often result in operational problems. These problems are associated with high-energy

    How Ball Mill Ore Feed Size Affects Tonnage Capacity

    For the purposes of this example we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6 500 micrometers. As a result the mill output will increase with this reduced size to approximately 77 000 tons per day.
