Product description:
High alumina ceramic grinding balls are featured by high intensity, high temperature and pressure resistance, good corrosion resistance to strong acid and alkaline, thermal shock stability, mainly used in chemical and grinding industry with high temperature, high pressure and strong corrosion working environment. They are the most ideal high-efficient grinding media for milling glaze materials. When it is working, the ball would not pollute the grinded materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
