high grinding media alumina ceramic ball
1. As the high grinding media and filling material to the powder processing equipment, this product is widely used in ceramic industry, cement industry, mining industry, paint industry, dope industry, chemical industry, steel industry, dye industry, glass industry, medical treatment industry and cosmetic industry etc. The characteristics are high density, high hardness, high wear resistance, high toughness and good erosion resistance etc.
2. Our ceramic alumina balls are produced by high quality raw materials and full set of automatic production process. The alumina ball has been sintered by high temperature with high stability, which has broken through the traditional ceramic grinding concept.
