  • CPE Lesson 13. Principle of Size Reduction

    Size reduction of solids involves creating smaller mass unit from larger mass units of the same material. Size reduction is a mechanical process of breakdown of solids into smaller size particles without altering the state of aggregation of solids. Many solid materials exists/present in sizes that are too large to be used directly.
