High Alumina Grinding Media

Ceramic beads made of aluminium-silicon oxide

Maheshwari® A 99.3 aluminum oxide beads have a high degree of purity with an Al₂O₃ content of > 99% and with secondary components of < 0.7%. These beads are ideal for use in agitator bead mills and in the wet grinding of aluminum oxide raw materials, e.g. for technical components, coatings and for high-quality paints and inks. The advantage is the availability of beads down to 0.5mm-60mm.
