Claim 0:
1. An inertia cone crusher comprising:
a body resting on a foundation over resilient dampers;
an outer cone and an inner cone arranged inside the body on a spherical support, the outer cone and the inner cone forming a crushing chamber in between, the crushing chamber being connected to a finished product discharge area,
an unbalance weight mounted upon a drive shaft of the inner cone using an unbalance weight slide bushing, the unbalance weight having a center of gravity that is adjustable relative to an axis of rotation,
the unbalance weight slide 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 tooth gear and a counterbalance weight, both being installed upon a counterbalance weight slide bushing, such that the tooth gear, the counterbalance weight, and the counterbalance weight slide bushing form a moving dynamic assembly,
the dynamic assembly being mounted on a fixed pivot resting on a flange, and rotatable around the fixed pivot via a journal plain bearing,
wherein the flange is rigidly fixed in a bottom part of the body;
wherein the journal plain bearing is arranged between the flange and the counterbalance weight,
and includes a base ring resting on the flange and an upper ring supporting the counterbalance weight slide bushing and the counterbalance weight;
an inner radius of the base ring being equal to an inner radius of the upper ring and to an inner radius of the unbalance weight slide bushing, and being equal to or greater than the fixed pivot's outer radius; and
a top surface of the flange has a mating recess for installing the base ring.
