Abstract: An inertia cone crusher includes a housing with an outer cone secured therein and an inner cone mounted concentrically with the outer cone on a spherical support. A bearing bush carrying an unbalanced mass member is installed on the inner cone shaft to engage with its spherical end thrust bearing a spherical support of the drive shaft of a power motor. A crank supporting a carrier member for engaging the unbalanced mass member is also secured to the drive shaft. The carrier member includes a weight unbalanced with respect to the axis of rotation of the unbalanced mass member, the weight having such mass and position that its static moment is about equal in value, and opposite to the static moment of the unbalanced mass member.

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.
