How to feed ball mill with steel balls

Update date: Dec 07

Oct 18, 2019 Steel Balls Diameter. General experience is: ball mill initial load should account for 80% of the total amount of ball, the proportion of the large ball and roughly the percentage of coarse ore is equivalent, the proportion of the small ball and roughly the percentage of fine ore is consistent. To accurately fill the initial amount of balls, the following formula should be used for calculation:
