(unknown) 8 years ago Like What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points.

A ball mill liner's lifespan will depend on the type of liner, the application conditions and the material being ground. Rubber liners, however, typically need to be replaced more often than cast iron liners. The benefits of replacing ball mill liners include increased efficiency and profitability of the customer's application.

In the first survey the ball mill was underperforming due to the low density in the mill, which was rectified in the second survey. The ball mill was grinding to a P 80 of 50 to 70 µm, therefore the traditional marker size (75 µm) was not applicable, and this can be seen by the increase in SSE for coarser sizes as the marker size approached P ...
