The energy efficiency of ball milling in comminution ... Similarly, the net efficiency of the ball mill will have the same value, in this case, for any monosize feed to the ball mill at any other size distribution, that is, any other X 50 of the product, since the lines for single-particle breakage and ball mill grinding are parallel.

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
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
