A combined multiple impact crusher with which granular material is slung outward over the rim of the rotor blade (3), impacts against an armour-plating (10) which rotates jointly with the rotor blade and the impact surface of which is conical in shape, and is further conducted obliquely downward in the radial direction to a second armour-plating (13) which rotates jointly with the rotor blade and has a conically shaped impact surface disposed below the rim of the rotor blade, after which impact the coarse and the fine fraction of the fracture fragments which are produced during the impacts are mutually separated with the aid of a height-adjustable dividing screen (15) disposed around the impact surface of the second armour-plating, after which the coarse fracture fragments, which are conducted over the rim of the dividing screen, are collected in an autogenous crush material belt in a trough construction (16) disposed around the dividing screen (15). |
