Abstract
The invention includes a rock crushing machine and method, the machine having a base and a jaw assembly secured to the base. The jaw assembly is adapted to receive rock as input material to be at least partially crushed. The jaw assembly is provided with an arcuate reaction surface that progressively engages the input material. A hollow crushing roll has an axial inner chamber that has an axis of symmetry (O). The crushing roll is a driven member that has an outside surface which forms a crushing zone between it and the reaction surface of the jaw assembly. Positioned at least partially within the crushing roll, an eccentric shaft serves as a driving member. The eccentric shaft has an axis of rotation (E), that axis being displaced from the axis (O) by a distance (T). A drive mechanism is coupled to the eccentric shaft so that as the eccentric shaft turns, rotational and centrifugal forces can be transmitted to the crushing roll by a torque transmitting device or other roll drive torque biasing mechanism.
