Replaceable wear liner

摘要

A replaceable wear liner pad assembly can be used to provide an array of tiles for lining a trough structure, the trough structure being made of a magnetically attractive material. The replaceable wear liner assembly includes magnetic members encapsulated within a resilient polymeric material, the polymeric material being transparent to magnetic fields. The polymeric material may have the general consistency of truck tire rubber. One side of the tile has a sheet or portion of a set gauge thickness such that in use the magnetic members are maintained at a set standoff distance from the underlying trough structure. The resilient material is far more flexible than the magnetic elements, such that the assembly can flex somewhat. The pad assembly is free of mechanical fasteners. Individual elements of the tile array may be replaced when worn, rather than the entire array. The underside of the pad assembly may provide a seal against the underlying trough structure to discourage leakage at the apertures formerly used for conventional wear liner stud assemblies.

1. A wear member comprising:
a body having at least a first accommodation defined therein; said body having a width, a breadth and a thickness, each of said width and breadth being greater in magnitude than said thickness; at least a first magnetic member, said first magnetic member being seated in said first accommodation; said body having a first portion, a second portion, and a peripheral wall; said first portion being made of a first material; said first portion extending predominantly width-wise and breadth-wise, and overlying said first magnetic member; said second portion underlying said first magnetic member; said peripheral wall extending about said magnetic member; said first material being a non-magnetizable, non-brittle, consumable wear material; said first material having a first modulus of elasticity; said magnetic member including magnetic material, said magnetic material having a modulus of elasticity; said first modulus of elasticity of said first material being at least an order of magnitude smaller than said modulus of elasticity of said magnetic material of said first magnetic member; said second portion being magnetically transparent; said body defining a footprint of said wear member for seating on a magnetically attractive substrate, and, when in use, said second portion extends between said first magnetic member and the magnetically attractive substrate, and maintains a stand-off distance therebetween; said first magnetic member has a first magnetic pole and a second magnetic pole; said first magnetic pole is proximate to said second portion; and said second magnetic pole is distant from said second portion.
