Abstract: An eccentric cone crusher having multiple counterweights. More particularly, the present invention provides a cone crusher including a frame, a crusher head for eccentric rotation about an axis, an eccentric member supporting the crusher head and having a center of gravity off the axis of eccentric rotation, and at least two counterweights attached to the eccentric. Utilizing more than one counterweight permits greater flexibility in positioning the counterweights, and minimizes moments and other stresses on the apparatus.

Abstract: A cone crusher alternatively operable with either a first bowl liner or a second bowl liner, the crusher including a frame, a crusher head, a bowl supported by the frame, the bowl including a bowl liner mounting surface, a locking mechanism on the bowl and the bowl liner for alternatively fixing the first bowl liner and the second bowl liner to the bowl, the locking mechanism including at least one locking assembly including a wedge member, a first link, a lock pocket defined by the bowl and being adapted to receive the first link, a lock mount defined by the bowl and being adapted to receive the first link, the lock pocket and the lock mount being respectively located relative to the bowl liner mounting surface such that the locking assembly is engagable with the locking flange of the first bowl liner when received by the lock pocket and such that the locking assembly is engagable with the locking flange of the second bowl liner when received by the lock mount.

Abstract: A cone crusher having a crusher head assembly including a crusher head having a cone-shaped surface and an underside opposite the cone-shaped surface, the underside having an annular socket engagement surface, a one-piece frame including a peripheral portion and a central portion, the central portion having a wall forming a socket having an upper edge providing a continuous annular head support surface engaged with the socket engagement surface, the upper edge of the wall defining an opening, the wall defining a socket bore extending from the opening into the central portion, the central portion having a hub located within the socket and extending into the socket bore; and an eccentric assembly supported on the hub, the eccentric assembly including an eccentric member engaged with the crusher head assembly and including a ring gear fixed to said eccentric member, the ring gear being housed by the socket bore in a position surrounding the hub, the gear ring being removable through the opening.
