Alumina Grinding Media Ceramic Balls/Beads are used large quantity in the world, because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strengthand resistance to thermal shock. This makes them all ideal choice for support of all types of catalyst.widely used for heat retention ,equilibration media,as ethylene dryers,High temperature Shift ,Low temperature shift,Ethylene cracking and drying.are widely utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas as petroleum, chemical industry, chemical fertilizer, natural gas and suport or protect the active catalyst , which especially have the comparatively good mechanical strength. Feature: * Excellent abrasion resistance * High purity * Excellent corrosion resistance * Energy saving of grinding and dispersion Main Technical Data * Chemical Composition: Al2O3 ≥ 99% * Specific Density: ≥3.9 g/cm³ * Vickers Hardness (HV5): 1300Mpa * Wear Rate: 0.03g/kg.h * Flexural Strength: 350Mpa * Breaking Strength (ø30): 55000N * Filling Density: 2.4 g/cm2 * Roundness: 95%
