Abstract

See full text

A gyratory crusher crushing head, removably mounted a crushing shell, includes a circumferential groove is formed in an outer facing surface of the crushing head. The groove is positioned towards a second lower end 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 resulting from forces tangential to the outward facing surface.
