Abstract: An inertia cone crusher comprises a housing having an outer cone and a spherical support of an inner cone which is installed concentrically with the outer cone. A cylindrical bearing bush carrying an unbalanced mass member is installed on the inner cone shaft and is connected to a power motor by means of a flexible link. The bush is connected to the housing by means of a spherical support, and for that purpose, an annular bore with a spherical surface is made in the housing, the bush has an annular outer projection on the end thereof facing the inner cone, and an annular "floating" end thrust bearing is provided between the annular projection and the spherical surface of the bore, the end thrust bearing engaging with its spherical surface the spherical surface of the bore.

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: An inertia cone crusher having a shell installed via elastic shock-absorbers on a base is provided with a crushing bowl, and a breaking head having a shaft mounted on a spherical support. An out-of-balance unit formed as a bearing bush is provided with an out-of-balance weight and a carrier disc and is installed on the shaft of the breaking head. A rod for mounting the out-of-balance unit on the breaking head has its lower end installed on the bearing bush. The upper end of the rod is installed in a bore of the shaft shank with a mounting clearance with respect to the rod end face and the out-of-balance unit is liftable and fixable in its upper position.
