Phosphate Bonded High Alumina Bricks 1550 Degree For Lime Kiln
Wear-Resistant Special Unburned Phosphate Brick For Lime Kiln
Phosphate bonded high alumina bricks are made from high alumina bauxite aggregate, selecting phosphoric acid or aluminum phosphate as binder. Finished phosphate bonded high alumina brick must go through 400~600 ℃ heating process and semi-dry compress process. Featured by high wear-resistance, high refractoriness and good thermal shock resistance, phosphate bonded high alumina bricks are widely used in rotary cement and lime kiln transition zone, sintering zone, cooling zone and cooler working layer.
