Phosphate bonded high alumina brick 1.high refractoriness under load, 2.high strength, good erosion and corrosion resistance
Phosphate bonded high alumina brick
With high quality bauxite as raw material, phosphate as binder, phosphate bonded high alumina brick is light burned brick which is characterized by high refractoriness under load, high strength, good erosion and corrosion resistance and great thermal shock resistance. The brick is used for burning zone and transition zone of medium and small cement rotary kiln.
