Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Size reduction: How to select the proper milling equipment
On-spec particles exit the mill for collection, and any oversized particles are rejected and captured for further milling. "Air classifying mills can reduce very large particles such as 6 mm grains of rice to very small particles under 50 µm in a single pass with minimal fines when other mills would take several passes," says Ozsoylu.
