High Hardness
Small Wear
Corrosion Resistance
The Description of Ceramic Grinding Balls:
Small wear, high hardness, corrosion resistance, impact resistance, economical and practical. Mainly used in non-ferrous metal mines, industrial ceramic powder materials, non-metallic powder materials, titanium dioxide, papermaking, coatings, inks, other powder materials and other fields; suitable for grinding media of various equipment such as sand mills, ball mills, stirred mills, flaking machines, polishers and sanders.
