Neodymium iron boron is a new type of strong magnetic material composed of elements such as neodymium, iron, and boron. It is widely used in the manufacturing of permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment, etc. After these products are scrapped, they become rare earth secondary resources; In addition, during the processing of neodymium iron boron magnets, 20% to 30% of the magnet waste will be generated. Recycling rare earth metals from waste neodymium iron boron magnets can not only protect the environment but also promote the sustainable development and utilization of rare earth resources.

Liming Heavy Industry has been deeply cultivating and working in the field of mineral powder grinding for nearly 40 years, and has the strength to build neodymium iron boron resource recovery production lines for customers. The entire production line uses Liming Heavy Industry's MTW European version grinding machine.

The process flow of European version grinding powder is:

1. Raw material conveying section

After calcination, the waste of neodymium iron boron enters the transfer warehouse, and the raw materials fall into the belt feeder.

2. Grinding and powder selection section

The neodymium iron boron waste is fed into the European version mill through a belt feeder for grinding. The ground material is sorted by a powder selection machine under the action of wind force, and the qualified finished powder is selected. It is collected and temporarily stored through a cyclone powder collector.

3. Finished product storage and transportation section

The finished powder is transported to the finished product warehouse for storage by a screw conveyor or other conveying equipment.
