The most distinctive features of the microcrystalline alumina wear resistant balls produced by datong is that they are unbreakable, high density, low wear loss. It can be used both for dry and wet grinding. Mainly used for ball mils, agitators, vibro-mills and sand-mils etc. They are widely used in industries of architectural ceramics, sanitary wares, enamels, zirconium silicate, kaoline, feldspar, refractories urea-formaldehyde molding powder, paints, coatings, etc.
Our company can provide two different kinds of alumina wear resistant balls formed by isostatic pressing or automatic rolling procedure according to the requirement of the customers.
Size range of the isostatic pressed balls: Ф30-Ф60mm
Size range of the rolling formed balls: Ф1-Ф30mm
