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. Beyond this, the situation may change.
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.Jun 01, 2018 The same policy is employed for the make-up charge where adding different ball sizes is done in order to optimize the mill performance. Chimwani et al. (2015) developed a simulation program that could predict optimal make-up balls to be added in order to achieve a required product fineness.
