Sag Mill Discharge End Assembly

SAG Mill Liner Design - Mineral Processing & Metallurgy

There are mills currently operating in which 90 percent of the liner downtime is chargeable to discharge end problems including bolt breakage, liner shifting and shell hole enlarging! The discharge assembly on either SAG or FAG must be stabilized to eliminate liner movement. This can be accomplished by bolting the pans separately to the head.

Overflow VS Grate Discharge Ball or Mill - Why Retrofit

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.

Ball Mill Maintenance & Installation Procedure
