A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary …
distributions at different rotor velocities for feed rate Q=2 t/h. Dynamics analysis, it has been shown that the impact energy per unit mass in vertical shaft impact crushers is greater than that in horizontal shaft crushers. It is useful for prediction of the performance of both horizontal and vertical shaft impact crushers.
