92% High-Alumina Ceramic Grinding Ball

Products introduction:

With microcrystal low-Soda Alumina calcined through high-temperature as raw material, coupled with extra-fine grinding by large-tonnage ball mill, centrifugal granulation and moulding process of dry-powder isostatic pressing, the density of alumina balls has been improved greatly, ensuring the uniformity in both density and shapes. Besides, their abrasion performance is 30-40 times higher than traditional grinding medium, guaranteeing the purity of grinding charge, which prolongs the product service life fundamentally.
