Ceramic rubber steel plate three-in-one composite liner is a hot vulcanization process, the toughened ceramic sheet vulcanized in the steel plate groove equipped with special rubber, the steel plate groove with countersunk head bolts. It can be made into various shapes, and the liner is made of composite materials of various thicknesses according to the abrasion conditions, forming a solid wear-resistant layer. Three-in-one wear-resistant ceramic liners are produced and assembled in a modular fashion, allowing replacement of high wear areas with good abrasion resistance. A special hot vulcanization process allows the rubber layer to be firmly bonded to the ceramic block. Three-in-one wear-resistant wear-resistant ceramic liner is widely used in thermal power, iron and steel, smelting, machinery, coal, mining, chemical industry, cement, port terminals, and other enterprises in the coal conveying, material conveying system, powder making system, ash discharge, dust removal system, and so on, all the wear and tear of the machinery and equipment.
