Product Description
Inert ceramic ball support media are the most widely used support materials globally due to their excellent consistency and reliability. These products are made from high-quality chemical-porcelain clay that offers outstanding stability, high mechanical strength, and resistance to thermal shock, making them ideal for supporting various types of catalysts.
The benefits of these materials include high density, high mechanical strength, and good wear resistance. Grinding porcelain balls are an economical, non-metallic grinding medium used extensively in industries such as machinery, electronics, aerospace, as well as in fertilizers and the chemical industry.
