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 socalled element tests. However, here at least two

The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
diagnostic studies in many cement plants. The paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by HOLTEC in a mio t/a cement plant.
Furthermore, the influence of the type of mill was investigated, including reactions performed in different planetary and mixer ball mills, in a stirred media mill, and with a mortar mill. Comparisons with the other solventfree synthetic routes showed that ball milling is an effective way of performing the reaction with low energy intensity.
