Abrasion-resistant ramming mixes for CFB  boiler is a kind of amorphous refractory material used in circulating fluidized bed boiler. In circulating fluidized bed boiler, materials are in a circulating flow state. Materials containing fuel, fuel ash, limestone and their reaction products will cause strong wear to the boiler lining. Wear-resistant ramming mass has excellent wear resistance and can withstand such long-term wear and extend the service life of the boiler.
