Overflow VS Grate Discharge Ball or Mill Why Retrofit

On smaller diameter Grate Discharge Rod Mills a discharge plug is furnished mounted on the trunnion liner and extending through to line up with the discharge head liners. The larger diameter Grate Discharge Mills are furnished with a discharge housing arrangement independent of the mill. A hinged door is mounted in this housing and easily

liming Ball Mills

diameter grate with discharge lifter assembly conveys the material to the discharge trunnion opening. The grate serves to retain balls, tramp, and coarse material. A gradient created between the feed opening and the discharge slots eases the flow of material. Application A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer. The feed to a ball mill is

Horizontal Grinding Mill Overflow Type, Grate-discharge

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 100 mesh. Compartment type

Ball Mills Mineral Processing & Metallurgy

The peripheral discharge type of Ball-Rod Mill is a modification of the grate type, and is recommended where a free gravity discharge is desired. It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired, and for dry grinding.

alternative type rod mill grate discharging machiner

the discharge end of the grate discharge ball mill has at least ten times the discharge opening area through the grate slots compared to the common trunnion overflow type mill. the discharge grates are designed to run clean and free of any blinding or choking. the pulp level in the mill may be varied by merely changing the pulp dilution.

Horizontal Coarse Grinding Mill Rod Mill Product

Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles present between each rod, while no fine particles receive impact and are ground. Therefore, the Rod Mill causes

TECHNICAL NOTES 8 GRINDING R. P. King Mineral Tech

For overflow mills K = 7.98 and for grate mills K = 9.10. This difference is ascribed to the presence of a pool of sl urry that is present on the bottom of overflow-discharge mills but not to the same extent in grate-discharge mills. This pool is situated more or less symmetrically with respect to the axis of the mill and therefore does not
