The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Overflow versus grate discharge ball mills an experimental investigation it has been widely accepted to go for grate discharge ball milling when a coarse product is preferred or to avoid production of extreme fines but overflow discharge mills are preferred for their simplicity of design and production of finer product in grate discharge.
Grate ball mill (grate discharge ball mill) is a ball milling machine used to grind various ores and other materials. Grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate..

· The center of the grate discharge end of this mill is open to permit adding of balls or for adding water to the mill through the discharge end. Instead of being constructed of bars cast into a frame, Grates are cast entire and have cored holes which widen toward the outside of the mill similar to the taper in grizzly bars.
To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is
Grate discharge ball mill: the ore is discharged through the grate plate. The grating part can strictly control the minerals discharge size that meets the demand, it has a good effect on fine particle grinding. 3. Peripheral type: discharge ore through the periphery of the cylinder. Continuous grind.

Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components
· Grate-Discharge Type. The grate-discharge type of Ball Mill has a grate at the outlet of the shell and causes less excessive grinding, compared to the overflow type. Therefore, generally, it is best suited to grind materials up to the particle sizes ranging from 60 to 10 mesh. Figure 4: Labelled Diagram of Grate Discharge Type. Compartment Type
