Abstract
A jaw crusher having a movable jaw support frame configured to facilitate interchange between shim and wedge settings. The support frame is configured specifically to minimize stress concentrations and to provide the time efficient interchange between wedge and shim settings without a need to weld, cut and machine regions of the support frame.
Claims15
A jaw crusher support frame arranged to support a movable jaw of a jaw crusher via a mechanically actuated link assembly connected to the movable jaw, at least a part of the link assembly being configured to allow the movable jaw to oscillate relative to a substantially stationary jaw in order to crush material in a zone between the movable and stationary jaws, the support frame comprising:
- a force transmission wall having a first side arranged to be forward facing towards the movable jaw and a second side arranged to be rearward facing away from the movable jaw, the first side having an abutment face aligned to extend generally in a plane transverse or perpendicular to a longitudinal axis of the link assembly;
- and
- a first and a second flange extending lengthwise along the wall and projecting widthwise forward from the first side of the wall to extend towards the movable jaw, a cavity defined between the first and second flanges being arranged to receive at least a part of the link assembly for contact with the abutment face, wherein a rearward end of each of the first and second flanges in the widthwise direction terminates at a first region of the wall and a second region of the wall positioned at or towards the second side of the wall projects rearwardly beyond the rearward ends of the first and second flanges.
