  • Size ReductionVisual Encyclopedia of Chemical Engineering

    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.
