Introduction:The phosphate bonded high alumina brick is made from sintered special grade high alumina bauxite, phosphate acid as binder, with high thermal stability and strength.Be applied in preheating zone,calcine zone,firing hood and cooler part of cement kiln.
Features:1.High strength.
2.Good slag resistance.
3.Good thermal stability.
4.Good abrosion resistance.
Application:The phosphate bonded high alumina brick is widely used for cement rotary kiln
