Neodymium iron boron powder production process

Neodymium iron boron is a high-performance rare earth permanent magnet material with outstanding magnetism and significant energy-saving effects. It is widely used in the scientific research and production of high value-added products such as wind power generation, hybrid vehicles, consumer electronics, robot intelligent manufacturing, energy-saving elevators, energy-saving oil pumping units, etc. This means that it will have high usage value and development prospects in future planning that focuses on energy-saving intelligent manufacturing.

As a comprehensive solution provider for grinding equipment, Liming Heavy Industriy has been committed to developing more efficient, energy-saving, and environmentally friendly grinding equipment. The MTW European grinding mill designed and developed by Liming Heavy Industry operates stably, with no dust during production, making it more environmentally friendly and an ideal neodymium iron boron grinding equipment.

The European version grinding machine is an upgraded product of traditional Raymond grinding and pendulum grinding, which applies multiple new technologies such as bevel gear overall transmission, grinding roller linkage pressurization, thin oil lubrication, and curved air duct. The output has increased several times compared to the past, and the energy consumption per unit capacity has decreased. The finished product has even fineness, which can meet the fineness standard of 250 to 350 mesh for permanent magnet materials.

Process flow of neodymium iron boron powder production:

1、 Raw material conveying section

After being calcined, the waste of neodymium iron boron enters the transfer bin, and the raw materials fall into the belt feeder.

2、 Grinding and powder selection section

The waste of neodymium, iron, and boron is fed into the European mill through a belt feeder for grinding. The ground materials are sorted by a powder concentrator under the action of wind power, and the qualified finished powder is selected and collected for temporary storage through a cyclone collector.

3、 Finished product storage and transportation section

The finished powder is transported downstream through pneumatic conveying equipment or other conveying equipment for the next stage.
