Slurry flow in mills: grate-pulp lifter discharge systems (Part 2)
2003年7月1日 Summary and conclusions. The slurry transportation in AG/SAG mills is a two-stage process consisting of flow through the grate and the discharge of slurry by pulp lifters into the discharge trunnion. The grate-only discharge condition provides the ideal relation between slurry hold-up and flowrate.

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 []

Overflow VS Grate Discharge Ball or Mill - Why Retrofit
Grate Discharge Ball mills with low pulp levels benefit from the full impact of the grinding media acting on the ore particles, as it falls into the shallow pulp. With a deep pulp level the grinding media is cushioned in the pulp, thus losing its energy and reducing its grinding ability. Grate Discharge Ball Mills have shown 25% to 45% more ...

Ball Mill (Ball Mills Explained) - saVRee - saVRee
Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
