Ball Mill vs SAG Mill: What's the Difference?

Ball Mills have a higher degree of efficiency than SAG Mills due to their smaller size and have more area for grinding particles, leading to faster grinding. On the other hand, SAG Mills have a larger and deeper drum that provides larger lifting force which increases grinding efficiency. In addition, due to its larger size, SAG Mills consumes ...

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.
