ZA Bead
ZAZirconia Toughened Alumina Bead
The ZA Bead, (DiaBeadsTM), is developed only for the metal and mineral mining industry,
with grinding machines of 500~10,000L large scale vessel volume and a very high tip speed.
It provides lower damage to the rubber lining of vessels than the 92% alumina bead.
- WGCC (≤2um) for paper coating
- Ultra fine grinding(≤25um) of metal mining industry
