Introduction
Silicon oxide grinding ball is made of high purity and fine talc ceramic powder by rolling, isostatic pressing and high temperature roasting. Silicon oxide ball is a economical type grinding ball with two choice of sphere and cylinder.
Application
Silicon oxide ball is suitable for dispersion and grinding low viscosity slurry. It can be used as grinding medium for paint, fuel, paint, glass, ink, gloss oil, pesticides, pharmaceuticals and other chemical and biological industries. Additionally, it can be used as medium for filter media, catalyst carrier, polishing and cleaning.
