    1. Introduction

    The alumina ceramic grinding beads are produced by rolling molding and isostatic pressing. The regular sizes are from 0.5mm up to 30mm. With the advantages of super low wear loss rate, it is mainly used in non-metallic mineral powder (such as zirconium silicate, kaolin, heavy calcium carbonate, etc.), coating, paint, food and other industries, as well as the polishing of metal parts. It is suitable for all kinds of ball milling, grinding and polishing equipment.

    Thanks to the world cutting edge technology with advanced raw material ultra-fine equipment, granulation equipment, automatic molding equipment and firing equipment, the quality of our alumina ceramic grinding beads enjoy good reputation in the world market.
