Put simply, particle size reduction is making big things smaller. For example, if you need large rocks crushed into gravel, that process is an example of particle size reduction. More officially, the definition of particle size reduction is the micronization and milling process to generate a more consistent particle size distribution. It's a…

Attrition Mills. 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.
