Washing and classifying also may be used in processing manufactured sand. The crushing process creates a significant amount of “fines,” which are undersized fine particles that pass through the smallest screen openings (which are measured by mesh sizes). The minus-#100 and minus-#200 mesh fines require washing to be removed.
