Ball Mill vs SAG Mill: What's the Difference?
Both mills differ in terms of the efficiency of grinding. 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.
