Product Name: Middle Alumina & High Alumina Grinding Ball for Grinding Machine Model NO.: BS-HAB Customized: Customized Color: White Size: Small Processing Type: Rolling Type Usage: Petroleum, Grind Content: >90% Material: Ceramics MOQ: 1 Ton Al2O3 Percent: 68%,72%, 92% Trademark: BESTN Transport Package: Plastic Woven Bag Specification: 3~100mm Origin: Pingxiang, China HS Code: 6909190000 Product Description Introduction:The microcrystalline wear-resistant alumina grinding ball is a high-quality grinding medium made of selected high grade materials, advanced molding technology and calcined in high-temperature tunnel kiln. Possessed with high density, high hardness, low wear, good seismic stability and good corrosion resistance the products are the most ideal medium for grinding glaze, blank and mineral powder processing, and are used as the grinding medium of ball mill in ceramics, cement, paint, refractory, inorganic mineral powder and other industries.It's able to make the products in different specifications as customers'requirements.Grinding Balls are suitable for grinding medium used in ball grinding machines.Typical CharacteristicsTechnical Data68 series75 series90 series92 series95 series99 seriesAl2O3 ≥68% ≥75%≥90%≥92%≥95%≥99%Fe2O3≤2%≤2%≤0.2%≤0.2%≤0.15%≤0.1%Volume Density ≥3.15≥3.20≥3.58≥3.60 ≥3.65≥3.85Moh's hardness ≥8≥8≥9≥9≥9≥9Shock ResistanceNo crack,No crushWater absorption≤0.02%≤0.01%≤0.01%≤0.01%≤0.01%≤0.01%AdvantageHigh wear-resistance:The alumina balls' wear-resistance is higher than the common alumina balls'. When it is working, the ball won't pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.High densityThe high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
