First Class Equipment, First Class Quality
By means of large-sized advanced equipment, such as ball mill, large-sized spray tower, lining tile presser, automatic wrap ball machine, constant static pressing machine and high temperature tunnel kiln, with it¨s workshop production technique flow reasonable and ordered, so as to obtain high quality products and ensure reliable and stable mass production.

Application of Alumina Ceramic Ball and Lining Brick

     Alumina Grinding BallApplication 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.
