Size of balls for ball mill

Aug 24, 2021

Dec 19, 2019 During the running-in process, the amount of steel balls is added for the first time, which accounts for 80% of the maximum ball load of the ball mill. Steel ball sizes are Φ120㎜, Φ100㎜, Φ80㎜, Φ60㎜, Φ40㎜. For example, the 100-150 tons ball mill has a maximum ball loading capacity of 9.5-10 tons. For the first time, 30% – 40% of
