### Crushing Efficiency Factors - Mineral Processing …

Note that crushing ratios in a ball mill are not well defined, but are believed to range up to 1.5 or even 2.0. In a second series of measurements, the particle size was not uniform—a distribution of particle sizes corresponding to a natural grading was used. Figure 3-18 shows the results compared with 100% efficiency for single-layer crushing. It is seen that for the same reduction ratio as ...
