The Latest of Grinding Technology & Market Trend of Neodymium-Iron-Born Magnet

Abstract

Neodymium magnets are a member of the rare earth magnet family and most powerful permanent magnets in the world. Nd-Fe-B magnets are used for hard disc voice coil motors, high efficiency motors for automotive use, high performance generators for wind power generation, and energy saving motors for industrial air conditioners and vacuum cleaners. With increased efficiency and space savings, uses of high performance magnets are increasing.

Neodymium-Iron-Boron （Nd-Fe-B） alloy are ground by jet mills such as the Micron Jet-T MJT or Micon Jet-Q MJQ. Both jet mills and its closed loop grinding system are widely used to the application.
