Abstract
Abstract A composite of rubber, natural or synthetic, and alumina-base ceramic, useful as a wear-resistant lining for ball mills, conveyors, chutes and the like, comprising a layer of rubber having embedded in and bonded to the surface thereof closely spaced shaped bodies of alumina-base ceramic. Such composite is made by molding and thereby bonding the rubber material to the shaped alumina-base ceramic bodies either directly or preferably through an intermediate bonding layer applied to the ceramic bodies prior to the molding operation.
