  • Cone crusher having inclined hold-down cylinders
    Patent number: 5464165
    Abstract: A cone crusher having a lower frame assembly and upper bowl assembly is provided with hold-down cylinders arranged in pairs which are oppositely inclined to counteract a rotational impact forces imparted to the upper bowl assembly. Additionally, the hold-down cylinders are inwardly inclined toward the gyratory axis of the crusher to exert a self-centering force on the upper bowl assembly. The paired and inclined cylinders form a conical truss arrangement that reduces the need for costly maintenance, repairs, and replacement of the hold-down cylinders.
