rotor speed of impact crusher

Heavy Hammer Crusher Speed

The high speed of the rotor permits the particles to exit via the exhaust ports to enter the crushing chamber. Crushing chamber is where the particles will spend the most of its time in the crusher. During the initial start of the crusher, and when the feed is given for the first time, particles build up along the outer space surrounding the rotor.

Tips for maintaining efficiency in crushing circuits – Quarry

Impact crusher is a kind of crushing machine which uses impact energy to break. When the material enters into the action area of the plate hammer, it is broken by the high-speed impact of the plate hammer, and it is thrown to the impact device installed above the rotor to break again, and then it bounces back from the impact liner to the action area of the plate hammer to break again.
