Grinding beads

Grinding beads,It is mainly used for the grinding and distribution of the CaCO3,kaolin, pigment, dye, graphite, coating ,bauxite

It can be  used for superfine grinding of relatively soft nonmetal powder such as Superfine heavy CaCO3,kaolin , talc, etc. This kind of micro bead on one hand can satisfy the above grinding of the nonmetal powder body on the aspect of property: it has the advantage of lower price. It may be said decent product with reasonable price,and is the first choice for many superfine grinding companies and grinding paint coating factories.

 

ZMC alumina ceramic beads
