Batch mill not level. (1 reply)

Our 12,500,lb cap. Ball mill is not level. This causes the charge to be 65% or so on one end and the other level is way below the balls on the other end.  I would think that this would not allow the material to grind properly on either end.

The mill would have to turn additional time and the end with materal below the ball level would be getting overground and also ball wear during each batch.

This also causes higher bearing temps on the heavier end etc....

Any info or thoughts would be appreciated so we can make any and all adjustments needed at one time.

What happens when you increase the water addition?  A higher pulp density might help to level out the charge.

Is the mill actually level, or is it tipped towards one side?

Are the lifters the same along the length of the mill, or are they more aggressive at one end?
