Zirconia balls

Zirconia balls not only have higher density, better wear resistance and impact resistance than alumina balls , but also have the characteristics of high strength, high toughness, corrosion resistance, non-magnetic conductivity , electrical insulations , etc., so it is the first choice for ultra-fine grinding and efficient grinding insulation .

Application: It is especially suitable for grinding in the fields of papermaking, textile, printing and dyeing, silk screen printing ink, offset printing ink, heavy calcium, kaolin, electronic slurry, metal pigment, medicine and food.
