Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters.


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 type ball mill belongs to low level forced discharge type grinding equipment. Used Mining Equipment | BALL MILLS Grate Discharge Ball Mills Grates can be added to the discharge end of the ball mill to facilitate a steeper pulp gradient which helps to prevent over-grinding. 2040 Ball Mills


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.
