Product Description Product Description Alumina Oxide Grinding Rolling Balls: Manufacturing Process and Characteristics 1. Manufacturing Process Forming Principle (Rolling Granulation):Alumina powder is mixed with a minimal liquid phase (water/binder) and fed into a tilted rotating drum/disc. Through continuous rolling friction and particle collision, the powder gradually agglomerates into spherical shapes. Key Process Parameters:Drum rotation speed: Directly influences particle collision frequency and forming efficiency (typically 20-50 rpm).Liquid content: Critical for powder wettability control (optimal range: 5-8% by weight). Excessive liquid causes over-agglomeration, while insufficient liquid hinders sphericity.Post-Processing:Drying: Removes residual moisture to prevent cracking.Sintering (1200-1600°C): Enhances structural integrity and mechanical strength through particle bonding. 2. Performance CharacteristicsMicrostructure:Higher open porosity (15-25% vs. <5% in pressed balls) and lower bulk density (2.8-3.2 g/cm3).Moderate interparticle bonding strength due to rolling-induced loose packing.Mechanical Properties:Impact resistance: Superior toughness (3-5x higher than isostatic-pressed balls) for high-impact grinding environments.Wear resistance: Porous structure accelerates localized wear but remains cost-effective for rough grinding (service life: 500-1,000 hours).Economic Advantages:50-70% lower capital investment vs. pressing/isostatic molding.Ideal for small-batch production (MOQ: 100 kg) and customized specifications. 3. Typical Applications Primary grinding of ceramics/minerals (e.g., quartz, feldspar).Low-cost media for pilot-scale ball mills.Impact-resistant grinding in vertical stirred mills. Application Classification and Applications of Alumina Grinding BallsAlumina grinding balls are categorized based on their Al2O3 content into three main types:Medium-Alumina Balls (60-65% Al2O3)Medium-High-Alumina Balls (75-80% Al2O3)High-Alumina Balls (≥90% Al2O3)High-alumina balls are further subdivided into 90%, 92%, 95%, and 99% purity grades. Due to their exceptionally high production costs, 99% alumina balls are rarely mass-produced and are primarily handcrafted by specialized ceramic manufacturers. Key Applications Medium & Medium-High Alumina Balls: Preferred for cost-sensitive applications, such as grinding ceramic blanks, due to their affordability.Widely adopted by mainstream ceramic factories.High-Alumina Balls: Ideal for precision grinding of hard, dense materials in ceramics, glazes, glass, and chemical industries. Valued for their superior properties: Corrosion resistance & contamination-free performance High density & thermal stability Exceptional wear resistance High strength & hardness Product Parameters Name17-23%Ceramic ball23-30%AL203 Ceramic ballMedium alumina ceramic ballHigh alumina ceramic ball 99-Alumina ceramic ballAl203+SiO2(%)>93>92>93>94>99Al203(%)17-2323-3040-75%85-9799Fe203(%)<1<1<1<10.2Ca0(%)<0.5<1.5<1.5<0.50.2MgO(%)<0.5<1.5<0.5<0.50.1K2O+Na20(%)<4<4<3.5<4>0.5TiO2<0.5≤0.5<0.1<0.10.5LeachableFe203<0.1<0.1<0.005<0.001 water adsorption<0.5%<0.5%<1<22-5grain densityg/cm32.3-2.42.3-2.42.6-2.93.43.2-3.6operation temp(max).C980980145015801580Moh's hardness>6.5>7>7>7.5>7.5compressive strength KN/Particleφ6mm >0.5>0.5>0.50>0.6>1φ25mm >6.5>6.5>4.9>55>8φ38mm >8.9>8.9>5.5>54>8φ50mm>9>9.8>6.5>7.8>15 Detailed PhotosAlumina Grinding Balls: Superior Performance forIndustrial ApplicationsAlumina grinding balls are widely utilized in ball mills across multiple industries, including: Ceramics Petroleum Fine chemical processing Building materials Metallurgy Machinery ElectronicsKey Advantages:Exceptional Material Properties:High hardness (Mohs 9)High specific gravity (3.6-3.9 g/cm3)Excellent high-temperature stabilityOutstanding mechanical strengthNon-contaminating to processed materialsSuperior wear resistanceEconomic Benefits: Currently represent the premium-priced grinding media on themarketUnder isostatic pressure, demonstrate 30-50% higher grinding efficiency compared to natural pebbles and silicon carbide ballsUnder optimized conditions (rotation speed, ball-to-water ratio):Significantly lower overall grinding costsIncrease single-machine output by 15-25%Reduce grinding time by 20-35% Technical Note:The isostatic pressing manufacturing process enhances particledensity uniformity,resulting in:More consistent grinding performanceReduced breakage ratesExtended service life (typically 5-8 times longer than conventionalmedia)Company Profile Company Overview Pingxiang Rongjian Environmental Protection Chemical Packing Co., Ltd. is a leading manufacturer of industrial chemical packing materials, headquartered in the Xiangdong District Industrial Park, Pingxiang City, Jiangxi Province.
