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 mineral) to maintain the volume, thus reducing energy consumption.
