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.

What are the Advantages of Wet Ball Milling?
Wet ball milling has several advantages over dry ball milling. Let's explore some of them: 1. Better Grinding Efficiency. The liquid in wet ball milling acts as a lubricant, reducing friction and improving the grinding efficiency. The particles are more effectively ground and dispersed, resulting in a finer particle size distribution.
