  • the aperture 34 in the lining member 30 is slightly larger than the shank of the countersunk bolt 38.1 so as to allow movement of the lining member 30 relative to the stationary bolt shank when abrasive material exerts a force on the lining member 30 to compress the backing member 50.

  • the resilient backing members 50 may be made slightly larger than the lining members 30 so that when installed the backing members 50 leave no gaps below the edges of the lining members 30. The longitudinal 15.3 and transversal 15.4 gaps between the lining members 30 will therefore not extend up to the shielded surface 20.
  • the inventor has found that with this arrangement, whereby the resilient backing members 50 are allowed to be compressed as loads from the abrasive materials are exerted on the lining members 30, the operational life of the lining members 30 are extended compared to the operational life of the lining members 30 should the lining members be secured to the shielded surface 20 directly. At the same time the occurrence of corrosion between the lining member 30 and the shielded surface 20 is practically eliminated in case of wet and abrasive material, as the backing member 50 effectively forms a seal against unwanted moisture ingress. It is also foreseen that a suitable adhesive may be applied between the backing member 50 and the shielded surface 20 and/or between the backing member 50 and the lining member 30.
