how does a grate discharge mill work
The discharge of the AG/SAG mill is fitted with a grate discharge, where ground material passes through slotted apertures into a pulp chamber that then lifts the material out the belly of the mill. The lifted material is then deflected into the trunnion and exits via a trommel into the mill discharge sump. Rod Mills .

Slurry flow in mills: grate-pulp lifter discharge systems
In this system of design, a minor part of the slurry flows back to the mill while the major part is discharged through the grate-pulp system. Also, at higher mill speeds (typically >80% of the critical speed) in addition to the flowback, a part of the slurry is carried over to the inside of the pulp lifter, which further reduces the discharge rate (Latchireddi and Morrell, 2003).

What are the Benefits of Pneumatic Discharge in Size
2012-11-2 There are three key benefits: 1.A properly designed pneumatic discharge system can increase production 300-400% over gravity discharge mills when grinding light materials to a fine particle size. 2.Without air, dusty material will take the path of least resistance, typically out the feed chute. In a pneumatic system, dust is controlled and ...

Converting a ball mill from overflow to grate discharge
2020-6-23 If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.
