Description of the ceramic chute liner
This product is under 350 ℃ high temperature environment to run for a long time not aging, don't fall off. Widely used in pneumatic conveying powder do wear lining pipeline equipment, such as the coal pulverizing system of coal-fired power plants, coal mill outlet piping, coarse and fine powder separator, an air duct elbow, induced draft fan, the machine inner shell, air preheater, the tail flue, medium speed mill cone bucket and other equipment. It can also be used for grinding lining on equipment such as steel mill, smelting plant dust removal system, duct bend and dust collector. At present, has successfully developed the 350 ℃, 500 ℃.
Wear-resistant ceramic liner is AL2O3 as the main raw material, with rare metal oxide as the flux, through one thousand seven hundred baidu high temperature roasting of special alumina ceramic, with special rubber and high intensity of a combination of organic/inorganic adhesive products. According to different usage, we have developed seven series and dozens of products, which can satisfy the wear-proof demand of various working conditions.
