A compact eccentric crusher includes a system and method for moving a crusher jaw from a crushing position to a maintenance position. When the crusher jaw is in the crushing position, the first end of the crusher jaw is mounted to the crusher frame and the second end is movable to adjusting the size of the crushing gap between a crushing roller and the crusher jaw. When the crusher jaw is to be moved to the maintenance position, the second end of the crusher jaw is secured to the crusher frame and the first end of the crusher jaw pivots away from the crusher frame. To allow the pivoting movement of the first end of the crusher jaw, the connection between upper bearing assemblies and the crusher frame are removed and the upper bearing assemblies are movable with the first end of the crusher jaw.

A compact eccentric crusher having a crusher jaw that includes a series of wear plates mounted to a frame. The frame of the crusher jaw includes a support surface that provide a mounting location for the wear plates. The wear plates are identical members mounted in an end-to-end orientation and retained on the support surface of the crusher jaw frame. An end stop is located at a second end of the frame and engages the lower wear plate. A master wedge is mounted at the first end of the frame and engages the upper wear plate. An auxiliary wedge is positioned between the wear plates and is secured to the frame to support the wear plates during operation of the compact eccentric crusher. The wear plates can be released and removed from the frame upon wear by removing the master wedge and lifting the wear plates from the frame.
