Grate Discharge Ball Mill Used in wet and dry grinding in both open and closed circuits, a grate discharge ball mill (sometimes known as a 'diaphragm discharge mill') incorporates a slotted discharge diaphragm with lifters at the discharge end of the mill. The diaphragm, or 'grate', serves to retain the balls and any coarse material,

The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by the steel ball charge and allow slurry to discharge effectively."
