Wear Resistance by 92% Alumina Ceramic in Coal Mill Pulverizer and Pipe Line

Alumina Lining 92% Al2O3 is of high wear resistance, acid and alkli resistance, effectively prolong the service life of equipment and considered to be the best choice of anti-wearing and anti-corrosion material; Wear resistance of ceramic is 266 times than that of special manganese, 171.5 times to high chrome cast iron; Hardness is much higher than that of wear-resistant steel and stainless steel.
Application: Oil, mining, steel and power industry.

The combination of high rigidity of ceramic and high elasticity of steel gives the pipe unmatchable features as an abrasion resistant, heat resistant and corrosion resistant material for use in the fields of power generation, metallurgy, mining, and chemical industry etc.. It has many advantages over steel pipes, cast stone pipes, and steel-plastic compound pipes.
