Through vulcanization, the alumina ceramic plates or ceramic tiles are embedded into the special rubbers (and steel) to form Impact resistant alumina rubber ceramic liner / plate / lining for large hopper, the first kind is rubber backed ceramic plate, which will be fixed on the abrasive surface of equipment by high-strength adhesive , and the other is rubber and steel backed ceramic plate, it is composed of rubber, alumina ceramic plate and steel plate, which will be fixed on the abrasive surface of equipment by bolts welded in the steel plate.
