Glass beads 1. chemical stability 2. low price Product Description: Grinding Glass beads are widely used as wet and dry grinding media adopted by micron powders processing, not only used in painting, 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. Normal Glass Beads: It features clarity, chemical stability and low cost used for grinding or shot blasting.
Intensive Glass Beads: It features good internality, wear-resistance, and chemical stability. The PH value is 7.2, which is suitable for grinding of materials with low or medium adhesive or shot blasting.
