Working Principle

Materials enter crushing chamber from feeding hopper, and are impacted to wear-resisting toothed plates on inlet by high speed hammers, this is the first crushing process.  Crushed materials with almost the same size enter the main crushing chamber for second crushing.  Materials from main crushing chamber are impacted between toothed plates and hammers for many times, and discharged from the outlet.  Final product size can be controlled by adjusting space between rotor and impact plates.
