A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand, or rock dust. Crushers are commonly used to reduce the size of materials for various purposes, including construction, recycling, and mining operations. They work by applying mechanical force to break the material into smaller pieces.
