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 ...

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...

A ball mill liner is a type of material that is placed inside a ball mill to protect the mill from wear and tear. The liner acts as a barrier between the grinding media and the material being processed, preventing excessive wear and damage to the mill. Ball mill liners also serve to contain the grinding media and prevent it from spilling out of ...
