A variable throw eccentric cone crusher. The cone crusher comprises a frame, a crusher head supported on the frame for gyration about a first axis, a bowl supported on the frame in spaced relation to the crusher head, and a mechanism on the frame for varying the eccentricity of the gyration of the crusher head. An eccentric member engages the crusher head and is eccentrically pivotable about a second axis radially offset from the first axis. The eccentric member is adjustable to vary the eccentricity of the gyration of the crusher head.

Variable throw eccentric cone crusher and method for operating the same

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.

Eccentric cone crusher having multiple counterweights

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.
