High alumina ceramic balls Catalyst support media

Detailed Product Description

High alumina ceramic balls Catalyst support media

1.Usage: widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories cement factories, enamel factories and glasswork ,also used as catalyst and adsorbent bed support in refining, petrochemical and gas processing applications, where low silica content or high density is required.

3.  Advantage: the excellence of high density, high hardness, and high wear resistance. During the abrasive/grinding processing, ceramic balls will not be broken; it will not pollute the material to be grinded,and in support media with unmatched impact resistance, thermal shock and crush strength etc.

4.Available sizes: 

We can provide two different kinds of high alumina ball formed by isostatic pressing or automatic rolling procedure according to the requirements of the customers.

Size range of the isostatic pressed balls: Φ40-Φ80 mm

Size range of the rolling formed balls: Φ1-Φ50 mm

5.Samples:sample for free,but you should pay for the freight for the samples.
