A wear sensing liner for a comminution apparatus. The wear sensing liner comprising: a liner body comprising; a wear surface side defining a wear surface; and an opposed, operatively rear surface side; and at least one sensor carried by the liner body. The at least one sensor being carried by the liner body to sense wear of the wear surface side of the liner body. The at least one sensor being configured to degrade in response to wear of the wear surface side of the liner body and to output a signal representative of the wear of the wear surface side of the liner body.

Mantle lifting device (10) has a body (26) configured to selectively engage and disengage an opening (24) of a mantle (12) by rotation in respective opposite directions about a central axis (28) of the body (26). The body (26) is provided with a lifting point (30) which is configured to couple with a lifting device such as a crane (not shown). The body (26) is in the general form of a plug having an upper surface (34) and an opposite surface (36) and tapered circumferential surfaces (38 and 40). The surface (40) is provided with indicia (43) commencing at a distance d on the surface (40) below the edge (42). This is used to indicate safe or unsafe lifting conditions. The indicia (43) being visible when the device (10) is engaged with the mantle (12) is an indication that the mantle (12) is worn to the extent that it may not be safe to lift the mantle (12) by way of the device (10), or at least not without additional safety precautions being taken.

A jaw assembly for a jaw crusher is disclosed where the assembly comprises a jaw stock (12), a wear plate (16), and a fastening device in the form of a bolt (34) with a square head (42) at one end and a washer (56) and fastening nut (52) positioned at an end opposite to the one end. The bolt (34) extends between the jaw stock (12) and the wear plate (16). The fastening device (34, 42, 56, 52) is operative to adopt a clamped configuration where the device provides a clamping force along a fastening axis to clamp the wear plate (16) at the jaw stock (12), and a released configuration where the fastening device does not prevent the wear plate (16) from being separated from the jaw stock (12). The fastening device (34, 42, 56, 52) is accessible from a direction that is transverse to that fastening axis, to enable the device (34, 42, 56, 52) to be changed from its clamped configuration to its released configuration.
