ABSTRACT OF THE DISCLOSURE A gyratory crusher includes a bowl assembly adjustably positioned relative an annular support ring mounted atop a fixed peripheral frame. Radial flanges on the bowl are verti- cally located by shims and retainer brackets containing the flanges which are then interlocked relative the support ring by hydraulically actuated means. A segmented clamp ring inter- mediate the bowl and support ring is provided with hydraulically energized means for clamping the bowl assembly to the support ring while a plurality of fluid cylinder assemblies carried by the bowl assembly are subsequently operable to break loose the locking action of the clamp ring to permit readjustment of the bowl assembly. During operation of the crusher a plurality of fluid load relief cylinders interconnecting the support ring and peripheral frame yield, in a unique controlled manner, to permit elevation of the bowl assembly, clamp ring and support ring, when non-crushable material is fed into the apparatus.
