Ceramic balls are centimeter sized spherical ceramic objects mainly made of high-quality kaolin, feldspar materials, or materials such as alumina, zirconia, silicon nitride, and silicon carbide, which are processed, formed, and sintered. Ceramic balls can be divided into three types according to their uses: filler ceramic balls, wet grinding ceramic balls, and dry grinding ceramic balls.Our balls are used for bearings, mills, chemicals, fertilizer, natural gas and environmental protection industries, etc. Material: Si3N4,Zro2,Al2O3,SiC Size: 2-50.8mm Colour: White,Black Standard: GB, AISI, AFMA, DIN, JIS or as the requirement Features: 1. High alumina content 2. High chemical stability 3. High density, high mechanical strength 4. Good wear resistance, anti-corrosion. 5. Never rust, and can roll without lubrication. 6. Free of metal contamination. 7. Non-magnetic 8. Electric isolation 9. No adhesive-wear with metal 10. Contact angular is very large with molten and nearly no reaction |
