The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
The purpose ofintermediatecrushing is to produce several coarse-grade products – for example, road base aggregates – or to prepare material for final recrushing. Generally the goal ofsecondary, tertiary, and quaternary crushing is to obtain the best possible size reduction at the lowest cost.
