Abstract: A device for clamping the adjustment ring 3 of a cone crusher with respect to a support ring 1 mated therewith by means of threads 2 comprises a check nut 4 and hydraulic cylinders 7 with spring-actuated piston rods 6 whose tips 8 are arranged in a groove 9, one of the surfaces of the groove being formed by a taper recess 5 of the clamping ring 4 and the other surface thereof being formed by the end surface 10 of the support ring 1. The piston rods 6 of the hydraulic cylinders 7 are arranged radially with respect to the axis of the check nut 4.

Abstract: The inertia cone crusher comprises a shell interconnected through vibration dampers to a crusher base and the shell carrying a crushing bowl which accommodates a breaking head. The shaft of the breaking head carrying an out-of-balance weight having its own rotation drive and axial support. The crusher shell also accommodates a countershaft which is a component of the out-of-balance weight drive. The shaft with one of its ends is movably connected (both axially and radially) to the driving member of the out-of-balance weight drive, whereas the other end of the countershaft is connected to the out-of-balance weight through an axially fixed ball spindle, whereby the latter serves as an axial support for the out-of-balance weight.
