ceramic ball

Ceramic grinding  balls are broadly utilized as the covering or supporting materials of the catalyst in the reactors and the packing in the columns in such varied areas, for example, petroleum, chemical industry, chemical fertilizer, natural gas and environmental protection etc. Upon request, we select the optimum packing for the particular problem or application as well as the optimum material and size.

Ceramic Ball Property According to the alumina content different, we have five kinds of balls, the detailed specification as the table.
