    impact crusher - an overview | sciencedirect topics

    Percussion crusher: The aggregates are produced by impact and hence higher fines content. • Hammer (impact) crusher: The feed is fragmented by kinetic energy introduced by a rotating mass (the rotor) which projects the material against a fixed surface causing it to shatter causing further particle size reduction. This crusher produces more rounded shape

    2.11 Influence of rotor eccentricity The installation of the rotor of the crusher is generally on the plane of symmetry of the two screen plates and at the center of the lower screen plate. In fact, this is not the best installation, but it is better to have a little eccentricity, because it is easier to destroy the circumfluent layer and thus increase the output
