The ceramic rubber steel plate 3-in-1 composite liner can be made in various shapes, and various thicknesses of composite materials are selected to make the liner according to the wear conditions, forming a strong 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 of ceramic to be firmly bonded, and each piece of ceramic has a penetrating bolt through the bottom steel plate, which is securely welded for double insurance. 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.
