The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces. There are two categories of crushers based on the way the force is applied to the material. For crushers of the first category apply force via pressure, the crushers of the second categor
