Alumina Grinding Ball 92% 95% Al2O3 Ceramic Media for Fine Grinding

23% Al2O3 Inert Alumina Ceramic Balls, also known as catalyst support media, are the most widely used support materials in chemical and petroleum industries. They are made from high-quality chemical-porcelain clay with stable properties, high mechanical strength, and excellent resistance to thermal shock. These inert ceramic balls ensure reliable performance under high temperature and high pressure conditions.

The ceramic balls have low water absorption, stable chemical properties, and strong resistance to acid, alkali, and various organic solvents. They can withstand frequent temperature changes during production processes. Their primary function is to increase gas or liquid distribution, support active catalysts, and protect the catalyst bed inside reactors. With proven stability and durability, inert alumina ceramic balls are widely applied in petroleum refining, chemical processing, fertilizer production, natural gas, and environmental protection industries.

Ceramic grinding media is designed for both wet and dry grinding. Ceramic grinding balls are known for low contamination and excellent wear resistance. Alumina grinding balls are widely applied in fine grinding of ceramic materials, pigments, glazes, and advanced powders. These grinding balls guarantee reliable and efficient milling results.
