Factory Direct Sale Rubber Backed Alumina Ceramic for Wear&impact Resistance
Rubber-backed alumina ceramic liners combine high-wear alumina tiles (Al₂O₃) or Silicon Carbide(RBSC) with a flexible rubber layer, offering superior abrasion resistance and impact absorption. These liners are ideal for:
Mining: Chutes, hoppers, slurry pipelines.
Cement: Raw mill liners, cyclone ducts.
Power Plants: Coal/ash handling systems.
