  • Super Microlite Alumina Beads
    Super microlite alumina beads is a kind of alumina ceramic, which can grind the zirconium and zirconium silicate materials. Our alumina ceramic grinding beads have been proven to be very effective as our bead are inert(no chemical attack), have a low wear rate, uniform microstructure and consistent performace during the fine grinding process.
    Super microlite alumina beads are particularly suited for tower mills, ball mills and IsaMills. The beads are availabe in a range of size, from 1.5mm to 60mm, thereby offering operators flexibility in terms of feed sizes to their mills. We can offer different material grades to suit your application.
