Phosphate bonded high alumina brick

Introduction
Phoshate bonded high alumina brick has two kind, phoshate brick and phoshate abrasion resistance brick. Using 42.5%-50% phosphoric acid as its binding agent and calcined bauxite as raw material, phosphate bonded high alumina brick is made by machine moulding.
With development of fire blocks, high RUL brick, composite brick, kyanite brick and high strength with good wear-resistance brick are be used as the substitute brick of phosphate bonded high alumina brick to solve other issues of rotary kiln.

Characteristic
1.High mechanical strength
2.Excellent abrasion resistance
3.High refractoriness
