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.

Size reduction in attrition mills occurs through the scraping of one surface against another. Particles scrape against each other or against a rigid face. In general, the size of the resulting particles can get near the micrometer level, but in the pharmaceutical industry, demand has increased for particles on the nanometer level.

Why Do We Need Comminution In Mineral Processing?

Crushing is the first operation of size reduction, while grinding comes after. Some processes, such as froth flotation and leaching processes, require a maximum particle area because maximizing the surface of solid in contact with the liquid or gas phase around enhances reaction, dissolution, catalytic effects, etc.
