Detailed Product Description
Application of Alumina Ceramic Ball and Lining Brick:
This products is a grinding body used in ball mill, pot mill librating mill and other fine breaking plants. It have advantages of high hardness, high density and anticorrosion. With the smashing efficiency and scuff-resistance much better than that of common ball-stone or natural cobblestone. It is widely used in ceramics, glass, porcelain enamel, pigment, chemicals and other trade.
