Abrasive rubber ceramic lining


Wear-resistant ceramic lining board is 3 oxidation 2 aluminium as the main raw material, with rare metal oxide as the flux, through 1700 ℃ high temperature sintering of special alumina ceramic, with special rubber and high strength organic or inorganic binder combination products. It has the following main properties and features:

(1) the hardness is large, and its rockwell hardness is 85-90.

(2) good wear resistance and long service life, its wear resistance is equal to 266 times of manganese steel and 171.5 times of high chromium cast iron.

(3) it has a wide range of use, and it has the adhesive type lining which is suitable for direct feeding of low temperature environment; An impact type liner that is fit for a large material strike; A straight - stick liner with high temperature and high temperature air conveying powder; It has adaptive fast tubular composite lining; There are fixed ceramic fan blades with high speed running.
