The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill. When ground products present a much coarse or much fine particle size distribution, the separation process ...

Is this a new mill with an ungraded ball charge? All the balls could be wearing out at the same time (if it is ball chips being rejected). Are you maintaining ball charge at a set volume or using mill power draw to maintain the charge? Have you inspected the grate to make sure it is still in good shape? Regards. Todd.

If you maintain a high ball charge with low tonnage, you'll overgrind. So you can low the ball charge, these means less interaction mineral particle with steel balls so reduce grinding, but also it means that you bed density will be lower, since you'll reduce the steel (7,75 kg/m) and replaced with mineral slurry (let say 2,0 kg/m for copper ...
