Read MoreMore About Crushers. August 20, 2023. Crushers are used to break up large pieces of rock and bulk materials. The size of the eventual pieces depends largely on the type of crusher unit used; some models are designed to merely break large stones into manageable segments, while others are engineered to reduce an entire workpiece to dust.
