Static Charge Ball Mill Copper Ore Highlights

1 plane ball mill liner is used in the fine grinding chamber the rise height of the grinding body depends on the static friction coefficient between the ball mill liner and the tree board 2 binding ball mill liner is used in the first grinding chamber which can make the grinding body rise higher with the greater impacting energy.
