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.
