Abstract
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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
164 words
An inertia cone crusher comprising: a shell; vibration dampers adapted for connecting said shell with a base; a crushing bowl mounted in the top portion of said shell for receiving material to be fed therein for crushing same; a breaking head with a cantilevered shaft extending downwardly, said breaking head being mounted in said crushing bowl for crushing the material entering the bowl; an unbalanced weight set on said cantilevered shaft of the breaking head; a rotation drive for said unbalanced weight having a driving member disposed on the base under said shell coaxially with the latter, a countershaft mounted under said unbalanced weight in the bottom portion of said shell coaxially with the latter, a flexible connection for connecting the lower end of said countershaft with said driving member, and a ball spindle intended for connecting the upper end of said countershaft with said unbalanced weight and mounted in such a way as to serve as an axial support for said unbalanced weight.
Claim 2
Dependent Claim
