alumina chemical filling ball high purity filling material abrasive medium catalyst covering material
Product name : Alumina ceramic ball
Specification : HY-TCQ-02
1.Product appearance : white spherical, 0.5-95mm in diameter, rolling or isostatic pressing.
2.Product use : with high strength, high hardness, high wear resistance, high specific gravity, small size, high temperature resistance, corrosion resistance, no pollution and other excellent characteristics and is widely used in different types of ceramics, glaze, glass, chemical plant of thick and hard material finishing and deep processing, is the ball mill, tank mill, vibration mill and other fine grinding equipment grinding medium, the grinding efficiency and wear resistance is much better than ordinary pebbles or natural pebbles.
Alumina wear-resistant ceramic microspheres are mainly used in non-metallic mineral powder products ( such as zirconium silicate, kaolin, heavy calcium carbonate, etc. ) and coatings, paints and other industries of material grinding and dispersion and metal polishing use, suitable for various types of wear and polishing equipment. It can also be filled in rubber water or coating when pouring to increase the wear resistance coefficient.
