NdFeB usually undergoes crushing and milling process during processing, and the process flow of the two processes is as follows:
Crushing: Firstly, use jaw crusher to break the large ingot into small pieces, then use medium crusher to crush it into 0.5mm3 size powder under nitrogen protection. The powder is transported in vacuumed, nitrogen-filled protective drums for the next powder making process. If it is dumping belt piece can be directly into the medium crusher. Hydrogen-broken products can directly enter the next powder making process.
Grinding: NdFeB powder fineness is more widely used is about 250 mesh, then generally use the European version of the mill or vertical mill, can be processed 250 mesh fineness of the powder, and the output of more than 5 tons per hour, and its own unique air self-circulation system, less dust emissions, the production line can be equipped with a pulse dust collector, dust removal efficiency, low emission concentration, basically to achieve the workshop dust-free operation, the equipment is stable, vibration, is the workshop dust-free operation, the production line can be equipped with a pulse dust collector, the dust removal efficiency, low emission concentration, basically realize the workshop dust-free operation. Stable equipment, low vibration, is a good equipment for grinding NdFeB!
NdFeB production line
(1) New energy automobile field: as the power source of new energy automobile, permanent magnet motor has the characteristics of high energy density, reliable operation, good speed regulation performance, etc. Compared with other types of motors, it can provide greater power output under the same quality and volume, and it is the ideal type of motor for new energy automobile.
(2) Energy-saving home appliances: With the continuous improvement of national energy-efficiency standards and the concept of low-carbon life taking root in people's hearts, green and energy-saving inverter home appliances have gradually become the consumer trend in the home appliance market. Inverter appliances mainly include inverter air conditioners, inverter refrigerators, inverter washing machines and other household appliances.
(3) Wind power: In the new energy and energy-saving environmental protection industry, wind power is one of the main application areas of China's high-performance NdFeB permanent magnet materials.
(4) Consumer electronics: NdFeB permanent magnet materials are widely used in cell phone speakers, receivers, etc. due to their high magnetic energy product, high coercivity and other advantages, which are in line with the trend of miniaturization, lightweight, thin and light consumer electronics products.
(5) Industrial motors: permanent magnet motors are characterized by simple structure, small size, high reliability, low loss and high efficiency, and are widely used in various fields such as industrial and agricultural production, aerospace, automotive, home appliances, medical equipment, electronic products, and so on.
