WEAR-RESISTANT FLEXIBLE LINING Russian patent published in 2003 - IPC

FIELD: lining of units and assemblies of mining equipment. SUBSTANCE: proposed wear-resistant flexible lining includes rubber plates and magnetic elements for securing these plates to housing; plates have two layers each : lower layer adjoining housing is made from magnetically hard rubber and is provided with ceramic magnets vulcanized in center and at corners; it is magnetized at magnitude of magnetic energy equal to (MM)_max = 5-10kj/cu.m; upper working layer is made from composite material containing 20-30% vol.-% of rubber on base of isoprene rubber, 60-65 vol.-% of barium ferrite powder and 10-15 vol.-% of samarium-cobalt alloy powder ; it is magnetized by surface arch magnetizing at magnitude of magnetic energy equal to (MM)_max = 6,0-6,5kj/cu.m; thickness of upper layer is more than or is equal to half distance between axes of magnetic power bands set by magnetizing inductor. EFFECT: enhanced wear resistance and durability of lining. 5 dwg
