• Crushers All crusher types for your reduction needs

    The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation. Primary crushing with impact crushersHigh reduction ratio crushing in conical/gyratory crushers,Referring to FIGS. 1 through 4, a first embodiment of a conical/gyratory crusher provided with residence time control of the material to be crushed in the crushing cavity between the crusher bowl liner and the mantle will be described.
