Licensing of low chromium alloy mountain microspheres are widely used in cement, building materials, metal mine, coal slurry, thermal power, chemical engineering, ceramic coating, light paper, magnetic materials and other industries with ultra-fine powder preparation processing. Products, high hardness, low wear, toughness, and broken small sphere in the course will further increase the surface hardness, wear resistance increased at the same time can increase mill production capacity, improve the recovery rate of the cement surface area and concentrate. Seven series now has more than one hundred varieties and specifications, selling domestic 31 provinces, municipalities and autonomous regions, more than 2,000 enterprises, and exported to Japan, South Korea, the United States, Australia, Southeast Asia and African countries.
