Grinding Glass Beads

Grinding Glass beads are widely used as wet and dry grinding media adpoted by micron powders processing, not only used in paint, dyement,and ink industries, but also used in magnetic, pharmaceutical, papermaking, China-clay and rubber industries.There are four types of glass bead grinding media available as below.
