Source Denver Equipment Company In today's ultra large ball mills of up to 28 diameter and 44 long; a 28 32% ball charge is your maximum. Source Paul Staples A grate (diaphragm) discharge ball mill will consume 15% more power than an overflow (open) discharge ball mill even though the grinding efficiencies are the same.
A grate assembly at the discharge en d of the mill permits retention of a higher ball charge (up to 50%) than is possible in an overflow mill which has a practical limit of around 40%. Behind the grates is a lifting compartment which picks up the ground material as it passes through the grates and transports it

Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is pumped out and discharged. Discharge Grates The natural flexibility of rubber has allowed rubber manufacturers to
