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.

How a Grate Discharge Ball Mill Works

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 ...

Side effects of converting Ball Mill from Grate to ...

Historically, grate discharge ball mills were used to avoid overgrinding and/or slimes generations when using larger ball size. At the time, smaller ball size did not exist and/or more expensive so that was the only way to achieve the grind economically. However, the paradox is that its use (grate discharge) also limits the size of grinding ...

How a Grate Discharge Ball Mill Works - grindingmedia.cc

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 out of the mill.
