Ball mill - WikipediaWorking[edit]. In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to.ball mill working with workers,Ball Mills - 911 MetallurgistDec 23, 2017 . Until recently many operators have believed that one particular type of grinding mill had greater efficiency and resulting capacity than some other type. However, it is now commonly agreed and accepted that the work done by any ball mill depends directly upon the power input; the maximum power input.
