ABSTRACT:
The present invention relates to a gyratory cone crusher having an eccentric member mounted within a lower main frame for rotational motion relative thereto. Disposed within the eccentric member is a crusher head assembly defining a first crushing surface which is adapted to gyrate relative a second crushing surface included within an upper bowl assembly attached to the main frame. Rotation of the eccentric member is facilitated by a plurality of V-belts extending between the eccentric member and a drive motor. Disposed between head assembly and the eccentric member and the eccentric member and the main frame are first and second bronze bearings which are interfaced to a lubrication system. The present invention further comprises slideably engaged shelf members rigidly attached to the main frame and upper bowl assembly for allowing the space separating the first and second crushing surfaces to be selectively adjusted via the actuation of one or more hydraulic cylinders pivotally connected to both the main frame and bowl assembly. A length of high pressure hose is wound about the bowl assembly to provide overload relieve to the cone crusher.
