A crusher wear resistant liner for positioning at a crusher bottom shell, the liner comprising: a plurality of wear resistant plates (200, 201) mountable at an inside of the bottom shell adjacent to each other to at least partially protect the inside of the bottom shell; each plate (200, 201) comprising side edges and a top and a bottom edge to define a perimeter of the plate (200, 201); each plate (200, 201) comprising: at least one interengaging formation (205, 206) configured to engage with an adjacent plate (200, 201) and/or an interengaging formation (205, 206) of an adjacent plate (200, 201), the interengaging formations (205, 206) configured to at least partially interlock adjacent plates (200, 201) and inhibit or prevent independent dislodgement of each plate (200, 201) from the liner; wherein the interengaging formation (205, 206) of at least some plates (200, 201) comprises a flange that projects laterally from at least one side edge of the plate and extends from a rear face of the plate a distance beyond the side edge to overlay a rear face of an adjacent plate so as to provide a laterally extending bridge connecting adjacent plates (200, 201); characterised in that: each interengaging formation (205, 206) comprises a panel-like body mounted to a rear face of each plate (200, 201). a plurality of wear resistant plates (200, 201) mountable at an inside of the bottom shell adjacent to each other to at least partially protect the inside of the bottom shell; each plate (200, 201) comprising side edges and a top and a bottom edge to define a perimeter of the plate (200, 201); each plate (200, 201) comprising: at least one interengaging formation (205, 206) configured to engage with an adjacent plate (200, 201) and/or an interengaging formation (205, 206) of an adjacent plate (200, 201), the interengaging formations (205, 206) configured to at least partially interlock adjacent plates (200, 201) and inhibit or prevent independent dislodgement of each plate (200, 201) from the liner; wherein the interengaging formation (205, 206) of at least some plates (200, 201) comprises a flange that projects laterally from at least one side edge of the plate and extends from a rear face of the plate a distance beyond the side edge to overlay a rear face of an adjacent plate so as to provide a laterally extending bridge connecting adjacent plates (200, 201); characterised in that: each interengaging formation (205, 206) comprises a panel-like body mounted to a rear face of each plate (200, 201). at least one interengaging formation (205, 206) configured to engage with an adjacent plate (200, 201) and/or an interengaging formation (205, 206) of an adjacent plate (200, 201), the interengaging formations (205, 206) configured to at least partially interlock adjacent plates (200, 201) and inhibit or prevent independent dislodgement of each plate (200, 201) from the liner; wherein the interengaging formation (205, 206) of at least some plates (200, 201) comprises a flange that projects laterally from at least one side edge of the plate and extends from a rear face of the plate a distance beyond the side edge to overlay a rear face of an adjacent plate so as to provide a laterally extending bridge connecting adjacent plates (200, 201); characterised in that: each interengaging formation (205, 206) comprises a panel-like body mounted to a rear face of each plate (200, 201).
