Dynabeads ZRA produced from a mixture of different rare earths using a sintered Zirconium Oxide or Aluminium oxide. These beads are very high crushing strength, especially designed for high performance. These beads as well provide high wear resistance to ensure a very long life span and contamination free grinding can be realized.
