reduction ratio of mill

CPE: Lesson 13. Principle of Size Reduction

Reduction ratios depend on the specific type of equipment. As a general rule, the coarser the reduction, the smaller the ratio. For example, coarse crushers have size reduction ratios of below 8:1, while fine grinders may present ratios as high as 100:1.
