STANDARD ALUMINA BEADS & BALLS 92%
Ceramic beads made of aluminium-silicon oxide
Maheshwari® A 92.0 aluminum oxide beads are ideal for wet grinding and processing of very hard products, e.g. in the area of paints, ceramic printing inks, glazes. In addition to the main component Al2O3, these beads also contain SiO2. These beads therefore have very good wear properties when used as grinding media. Another advantage is the availability of very small bead sizes < 0.5 mm upto 60mm.
Technical Data:
Al2O3 91.0 – 93.0 % and SiO2 > 5.0 % and others ≤ 4.0 %
Specific Weight ≥ 3.7 kg/dm3
Bulk Density ≥ 2.2 kg/dm3
Roundness ≥ 0.93 (ratio width/length (xmin/xmax))
Colour:
Fields of application
In the mining industry A 92.0 ceramic beads are used for the grinding of minerals and precious metals.
Quality attributes
The ceramic beads type A 92.0 have a dense sintered structure, a smooth surface, high roundness and high hardness.
Advantages: -
High purity raw materials
- Useable for high-grade grinding of pigments, dyes, inks, especially for very hard materials
- Useable for grinding of minerals and precious metals in the mining industry
- Useable in wet grinding processes
- Useable for all modern mills and high energy mills.
- No radioactivity in comparison to ceramic beads made of zirconium silicate and therefore
no contamination of the grinding product and no costly disposal of the beads.
- Environmentally friendly.
