Claim 16:
17. An inertia cone crusher comprising:
a housing;
an outer cone and an inner cone arranged inside the housing on a support, the outer cone and the inner cone forming a crushing chamber,
an unbalance weight mounted upon a drive shaft of the inner cone using an unbalance bushing, the unbalance weight having an adjustable center of gravity,
the unbalance bushing being connected to a transmission disk coupling that includes a driving half-coupling, a driven half-coupling, and a floating disk arranged between them,
the transmission disk coupling being connected to a counterbalance weight, both being installed upon a counterbalance bushing, such that the counterbalance weight, and the counterbalance bushing are rotatable around a fixed pivot via a bearing,
wherein the bearing includes a base ring resting on a flange and an upper ring supporting the counterbalance bushing and the counterbalance weight, and
wherein an inner radius of the base ring is equal to an inner radius of the upper ring and to an inner radius of the unbalance bushing, and equal to or greater than the fixed pivot's outer radius.
