What Is High Alumina Grinding ColumnAlumina grinding column refers to the high-temperature calcined Alpha alumina powder as raw material, through batching, grinding, powder making, molding, drying, firing, and other processesAlumina ceramic grinding columns make great ceramics, glasses, and enamels in chemical factories and other industries with ball mills, can-type mills, and vibration mills as their main machinery. Al2O3 Alumina grinding cylinder can also be used in these industries: metallic minerals, non-metallic minerals , silicon carbide, talcum, white pigments, cosmetics, cement, building materials.High Alumina Ceramic Grinding Column applicationsApart from grinding usages, you can form rubber-backed ceramic wear liners with our alumina grinding cylinders. The main application for  Alumina Ceramic Column is within the mining industry.We suggest Al2O3 alumina grinding cylinders for stirred mills and ball mills preferably. Alumina grinding columns are widely used in different types of ceramics, enamels, glass, chemicals, etc. due to their excellent characteristics such as high strength, high hardness, high wear resistance, large specific volume, small volume, high-temperature resistance, and corrosion resistance.high Alumina Grinding Column advantageThe alumina grinding column has a grinding efficiency and abrasion resistance far exceeding ordinary ball stone and natural pebbles. It is an excellent grinding medium for fine grinding equipment such as ball mills, pot mills, and vibration mills.No abrasion, no corrosion, and no erosion. Alumina ceramic grinding columns resist almost everything. Acid, alkali, chips, extreme heat, and abrupt temperature changes, etc. Al2O3 Alumina grinding cylinder are also pollution-free, easy to clean, and 3-5 more durable than natural stone liners, and 23 times more durable than rubber liners. Installation and milling time are reduced at a minimum, while efficiency is augmented at a maximum.• Wear-resistant low loss• high-temperature resistance• corrosion resistance• High Mechanical StrengthHigh Al2O3 Alumina Ceramic Grinding cylinder specificationSpecification (mm)Diameter (mm)Height (mm)Φ15*151515Φ20*202020Φ25*252525Φ30*303030Alumina ceramic grinding Column Chemical Composition and Physical PropertiesAl2O3≥ 92%≥ 95%Fe2O3≤ 0.01%≤ 0.01%SiO2≤ 5.28%≤ 2.6%Na2O≤ 0.72%≤ 0.44%Hardness9 Mohs9 MohsWater Absorption≤ 0.01%≤ 0.01%Bulk Density≥ 3.6g/cm3≥ 3.7g/cm3Compression Strength≥ 2000 Mpa≥ 2500 MpaWear Loss≤ 0.001%≤ 0.0008%Note: As the grinding media, at a comparable weight with grinding balls, Al2O3 alumina ceramic grinding column have an approx.14% greater surface than alumina ceramic grinding ball.

This alumina grinding media possesses excellent thermal properties. So you can grind down to the particle size you need to achieve.Better for some applications than porcelain, flint pebbles, or natural stones, Ultraming Alumina grinding balls are precisely engineered, down to the nanometer.Because when it comes to your ball milling process, every nanometer counts.DESCRIPTIONPROPERTIESShapeSpherical, cylindricalColorWhiteAlumina60%, 75%, 92%Ball size0.5-30 Rolling Type25-60mm Pressed TypeHardness7-9MohsSelf Wear Rate≤0.08g/kg.h
