Steatite Ceramic Grinding Media and Lining is a magnesium metasilicate mixture manufactured from premium stone, clay, barium carbonate, and some other byproducts. The Steatite Ceramic Grinding Media and Lining is fused in high-temperature furnaces to create an impermeable, vitrified, resilient, non-porous, thick tough solid. Steatite ceramic is thought to be the most ideal ceramic composite for ball mill linings and grinding media due to its mechanical strength and other related characteristics.ï
