When grinding rare earth alloys residue deposits of difficulttogrind components are frequently formed. In the case of NdFeB alloys these consist mainly of neodymium, other rare earth fractions or iron. The residues are ductile and are difficult to grind in jet mills. Instead they tend to accumulate in the grinding chamber.
The dual centrifuge DeltaVita® is based on the further development of a classical centrifuge. In contrast to a conventional centrifuge rotor, the rotor is equipped with two rotary plates at a specific angle to allow for the proper rotation of the grinding media in the sample vessels to reduce the particle size similar to agitator bead mills.
