High alumina grinding balls are used in ball mill, pot mill, librating mill and other fine breaking plants with advantages of high hardness, high volumetric density and anti-corrosion. With the smashing efficiency and scuff-resistance much better than that of common ball-stone or natural cobblestone, it is widely used in ceramics, glass, porcelain enamel, pigment, chemicals and other trade. For non-metal mineral products extra refining, our grinding balls are the ideal grinding media for stirring[...]

The molecular sieve is a kind of the crystal aluminosilicate attributing to its even pore size and much higher specific surface areas. There are many excellent merits: (1) The selective absorption as the different size and shape of molecules, that is to say, it only absorbs those molecules of which the diameter is less than the pore size of molecular sieve. (2) To those smaller polar molecules and the unsaturated molecules, it has the property of selective absorption. The bigger the[...]
