A crusher, also known as a stone crusher, is a pulverizing machine used in the processing of metallic and non-metallic minerals to break mined raw ore into smaller particles through compression and bending.
A crusher is defined as a pulverizing machine in which particles larger than three millimeters account for more than 50% of the total discharge. Crushing operations are often classified into coarse crushing, medium crushing, and fine crushing according to the size of the feed and discharge particles.
