Ball Mill Grinding Theory
Apr 28, it is now possible to compute the screen analysis of the working charge of balls in the second-stage mill (see table 13). if the ball charge in the second-stage mill is screened once a month, there will be 14,940 balls less than 1 in. in diameter to.Aug 06, a sag mill trommel screen lets you control the true discharge size of your sag mill or the transfer size to the downstream ball mill circuit. a well sized trommel should not let rocks pass to the ball mill if they are to be more than say 5/8″ or 16mm. in the image case below, strangely enough, metso is the mill shell liner and discharge grate.
