Product Description————————
1. Alumina grinding beads is also called Alumina grinding ball or Alumina ceramic ball or Alumina bead or ultrafine grinding media.
2. Alumina material has advantages of high hardness, high strength, high
tenacity, high wear resistance and good corrosion resistance which
is widely applied in fields of ceramics, fire proofing material,
machinery, electronic, photics, Aeronautics and astronautics,
biology and chemicals and etc.
3. It owns gloss of pearl and smooth surface and is the best ball
among all grinding media.
Application————————
1. Particularly suitable for vertical stirring mills, horizontal
roller ball mills, vibrating mills and various high linear, speed
pin- type sand mills.
2. For wet or dry ultrafine dispersion and grinding of pastes and
powders without contamination.
3. Perfect grinding media with good flatness, smooth surface,
bright,high density and high strength.
4. Wear and corrosion resistant product: coating, textile, pigment,
dyeing.
5. High strength, high tenacity product: magnetic material,
piezoelectric ceramics, dielectric ceramics.
6. Pollution prevention: medicine, food, cosmetics.
7. Ceramics: electronic ceramics, refractory ceramics, structural
ceramics.
