The shell of the breakers is mounted on the upper part of the housing of a cone crusher in such a way that when expansion of the shell occurs under operation of the cone crusher the mounting bolts are not twisted or sheared and at the same time are readily accessible for replacement. Thus the shell is provided with a number of symmetrically spaced pockets around the middle part of its outer surface, each of these pockets extends through a corresponding opening in the casing and is connected to a mounting bolt for attaching to the casing through the intermediary of a two-arm lever directed radially away from the shell. |
