Alumina Ceramic Bead Grinding Media

Alumina Ceramic beads are highly resistant to impacts, fractures, wear, heat, corrosion,  electricity insulators!  Alumina grinding beads are also high hardness, chemically and thermally stable, and they produce less abrasion.

WHAT IS Alumina ceramic grinding beads

These alumina ceramic grinding beads are appropriate for both wet and dry extra-fine grinding of powders of non-metallic minerals and materials, such as alumina, feldspar, quartz, zirconium silicate, kaolin clay, inks, glaze, and ceramics in stirred and ball mills. Alumina beads (Alumina ceramic beads) is made in highly Purified alumina powder. We can supply 95% Al2O3 Alumina grinding beads with Dia. from 0.5mm to 20mm.

Alumina beads grinding media application

High-quality wear-resistant alumina beads (Alumina ceramic beads) are mainly used for the ultra-fine grinding of non-metallic mineral powders. They are the grinding media for stirring mills, sand mills, and vibration mills. Ceramic grinding beads are suitable for ultra-fine zirconium silicate, quartz, alumina, corundum, Grinding of silicon carbide, ultrafine titanium dioxide, feldspar, zeolite, wollastonite, talc, heavy calcium carbonate, kaolin and other materials. Applications are often linked to the chemical and coating industries, but alumina grinding beads can also be used to produce inks, dyes, paints, rubbers, etc.  Al₂O₃ alumina ceramic grinding beads suitable for large mixing mill, peeling machine, ball milling machine, and other high speed grinding equipment.
