With more than 30 years production experience, we supply our customers a complete range of Zoomber alumina grinding beads with the size range from 1mm to 30mm and the alumina content from 60% to 99%. We can also make customized product for our customer based on special requirement. Applications: With high strength and hardness, excellent wear resistance and corrosion resistance, alumina beads are widely used in the fields of ceramic, glass, enamel paint, and chemical engineering industries. Characteristics: with high density, good impact resistance, good wear resistance, smooth surface, high purity, our products can reduce the influence on the grinding materials for most extent. We will offer our customers with suited price.
