A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. In industry, crushers are machines which use a metal surface to break or compress
