The Impact Crusher or impactor, is one of several types of crushing machines, including jaw crushers, hammer mills, and cone crushers, that is manufactured for the purpose of processing raw materials, like concrete or asphalt, among many others, to reduce them in size. It is widely used and of high production efficiency and good safety performance. 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.
