The ball mill is selected according to the hardness, grindability, particle size and output of the mineral. The lining shape and ball (segment) are tailored according to years of engineering practice experience, maximize the grinding efficiency of the ball mill. Reduce product energy consumption.

### Ball Charge and Grinding Efficiency - Grinding ...

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.

### The energy efficiency of ball milling in comminution ...

If the energy to produce new surface by single-particle breakage is used as the basis for evaluating efficiency, then the efficiency of ball milling has a more realistic value of about 15% for the comminution of quartz and soda-lime glass.
