High strength phosphate wear resistant brick

This product is based on the ordinary phosphoric acid combined with high alumina brick, through the process,

using chemical additives, the strength, wear resistance and load softening temperature of the product are

greatly improvedThe high temperature performance and thermal shock resistance of the brick are better than

those of phosphate bonded high alumina brick. The product passed the provincial technical appraisal in 1991

and won the national Spark Award in 1993Achievement exhibition Gold Award and Ministry of building materials

Gold Award. P brick has the characteristics of high compressive strength at room temperature, good thermal

shock stability and low porosity, which is suitable for cement rotary kilnKiln tail, cooling zone, cooler and high

temperature zone of cement shaft kiln.

Ba611 high performance wear-resistant plastic (ramming material)

High performance wear-resistant ramming material is suitable for large-scale cement industry, such as preheater,

grate cooler, vertical mill, dust collector, tertiary air pipe and variouskiln pipesWear resistant ramming material.

The material is used in the pipeline. The pipe and steel plate arewelded with nail or tortoise shell net, and the

wear-resistant material is 25-35mm as lining material, which hasa long service lifeUp to 5-6 years without replacing

pipes and steel plates.
