Ceramic balls are widely used as the covering or suporting materials of the catalyst in the reactors and the packing in the columns in such varied areas,for examples,petroleum,chemical industry,chemical fertilizer,natural gas and environmental protection etc.The ceramic balls have the advantages of high temperature and high pressure resistance.low water adsorption,stable chemical performance,it also resistance to acid,alkali,and some organic solvent.
High alumina grinding ceramic ball:
92%Al2O3 grinding ceramic ball, 95%Al2O3 grinding ceramic ball
Middle alumina grinding ceramic ball:
Micro-crystal middle alumina, carborundum middle alumina
1.high density,longer and superior milling life
2.uniform quality and shape
3.wide range of sizes,high wear resistance
4.immediately delivery,excellent service,satisfactory price
5.good sheen,good normalization
6.low water absorption
7.good corrosion resistance
