(1)Produced by sinter process
(2)High crushing strength,
(4)High whitness and High spheric
It is mainly used for superfine grinding of relatively soft nonmetal powder such as
Superfine heavy CaCO3,kaolin , talc, etc.
(1)Smooth and shinning surface makes cleaning an easy job.
(2)High grinding efficiency make the powder refining quickly
(3)High whiteness prevents the material from contamination
(4)Lower packing density can make the beads do not produce excess collision among
