Impact crusher is a machine that uses striking as opposed to pressure to reduce the size of stone material. Impact crushers are designated as a primary, secondary, tertiary, or quarternary rotor crusher depending on which processing stage the equipment is being utilized. Stone impact crushers are utilized in aggregates production, mining operations, as well as in recycling applications.
Rock impact crusher breaks up the material by either striking it with a rapidly moving blow bar or by throwing it into a stationary anvil where it breaks upon impact. Impact crusher accelerates the feeding material with high speed and then flings the fast-moving rocks against the walls of the crushing cavity and each other. This collision and impact cause the stone materials to break down to smaller sizes.
