摘要

A gyratory crusher crushing head (103) having a circumferential groove (206) formed in an outer facing surface (203,204,205) of the crushing head. The groove is positioned towards a second lower end (209) at the outward facing surface relative to an axial length of the crushing head. The groove and its relative axial positioning minimizes the stress concentrations at the crushing head resultant from forces tangential to the outward facing surface upon which is removably mounted a crushing shell (102).
