Abstract:
A gyratory crusher main shaft assembly in which an axially upper region (113) of the main shaft comprises a tapered conical section with a protective sleeve friction (124) fitted over the cone. To facilitate mounting and dismounting of the sleeve (124), at least one groove (121) is indented within a radially external facing surface of the main shaft at the region of the cone to allow fluid to be introduced under pressure to the region between the sleeve and the cone.
