METHOD OF MAKING A MAGNETIC MATERIAL AND A FLUIDIZED BED MIXER FOR MAKING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18049012 titled 'METHOD OF MAKING A MAGNETIC MATERIAL AND A FLUIDIZED BED MIXER FOR MAKING THE SAME

The abstract describes a fluidized bed mixer used for combining neodymium-iron-boron alloy powder with dysprosium or terbium alloy powder or elemental metal powder to manufacture magnets. The mixer ensures homogenous mixing by covering the outer surfaces of the first powder particles with the second powder.

  • The fluidized bed mixer combines neodymium-iron-boron alloy powder with dysprosium or terbium alloy powder or elemental metal powder to make magnets.
  • The mixer uses a fluidized bed portion, cascading baffle system, and combined powder collection area for efficient mixing.
  • It ensures that the second powder material adheres to and covers the outer surfaces of the first powder material particles.
  • The method results in a homogenous mixture of the two powders, essential for magnet manufacturing.

Potential Applications: - Manufacturing of high-performance magnets for various industries such as electronics, automotive, and renewable energy. - Research and development of advanced magnetic materials for specialized applications.

Problems Solved: - Ensures thorough mixing of neodymium-iron-boron alloy powder with dysprosium or terbium alloy powder for consistent magnet properties. - Prevents segregation of powders during the mixing process, leading to uniform magnet composition.

Original Abstract Submitted

A fluidized bed mixer for combining a first powder with a second powder for manufacturing a magnet and a method of using the fluidized bed mixer for making the magnet. The first powder material is an alloy powder containing neodymium (Nd), iron (Fe), and boron (B), and the second powder material is an alloy powder or elemental metal powder containing one or more of dysprosium (Dy) and terbium (Tb). The fluidized bed mixer includes a fluidized bed portion in an upper portion of a mixing chamber, a cascading baffle system beneath the fluidized bed portion, and combined powder collection area beneath the cascading baffle system. The fluidized bed mixer is configured to homogenously combine a first powder material with a second powder material in such a way that particles of the second powder material adheres to and covers the outer surfaces of the particles of the first powder material.
