management. This makes it difficult for a fixed-speed mill to operate efficiently and is one of the reasons why SAG mills and some ball mills utilize variable-speed drives (VSDs). It is this “actuator” — i.e., varying mill speed — that is exploited by SmartMill™ to increase grinding efficiency, reduce …

### Optimization of mill performance by using

operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree.

What is the efficiency of a milling process? Different possibilities to define energy efficiency: 1. Specific energy of mill compared to new created surface energy → not meaningful, efficiency much smaller that 1% 2. Specific energy of mill compared to minimum specific energy requirement in so-called element tests. However, here at least two

### Cement mill - Wikipedia

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
