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 natural pebbles. It is widely used in ceramics, glass, porcelain enamel, pigment, chemicals and other trade.

High-density, ultra-high fired Burundum is the ideal medium for wet or dry milling. High specific gravity and cylindrical shape give it greater weight per volume, more contacts per mill revolution, greater area of attrition, with each contact. Result: faster, finer grinding or dispersion, often cutting milling time in half.
