Product Characteristics
The unique microstructures of Yiho Alumina Balls result in hard, chemically inert grinding balls, that are corrosion resistant, non toxic, non magnetic, and non porous.
This alumina grinding media possesses excellent thermal properties. So you can grind down to the particle size you need to achieve.
Better for some applications than porcelain, flint pebbles, or natural stones, Yiho Alumina grinding balls are precisely engineered, down to the nanometer.
Because when it comes to your ball milling process, every nanometer counts.
Application
Alumina grinding media ball is mainly used in ceramic, glaze, paint, zirconia silicate, aluminum oxide, quartz, silicon carbide, talc, lime carbonate, kaolin, titanium and other materials grinding, and mechanical equipment accessories.
Properties
High density, high hardness, low wear loss, regular shape, impact resistance, corrosion resistance, etc.
