The microcrystalline wear-resistant alumina ball is a high-quality grinding media made of selected high grade materials, advance molding technology and calcined in high-temperature tunnel kiln. Possessed with high density, high hardness, low wear, good stability and good corrosion resistance, the product are the most ideal media for grinding glaze, blank and mineral powder processing, and are used as the grinding media of ball mill in ceramics, cement, paint, refractory, inorganic mineral powder and others industries.
