Abstract (en)

The present disclosure relates to a retaining assembly (102) to secure an inner crushing shell (101) at a shaft-mounted head center (201) of a gyratory crusher. The retaining assembly (102) has a modular construction comprising an inner head nut (203), an inner ring element (208), an outer ring element (207), first fastening members (301) and second fastening members (302) and a cover plate (205). The inner ring element (208) and the outer ring element (207) are rotationally locked together preferably with the help of locking elements (304) which are positioned radially between the two ring elements (207, 208). After the retaining assembly (102) is tightened, the attachment ring (206), upon application of heat, welds the shell (101) to the outer ring element (208).
