Description

technical field [0001] The invention relates to the field of neodymium-iron-boron, in particular to a recovery device in the grinding and cutting process of neodymium-iron-boron. Background technique [0002] Neodymium iron boron, simply speaking, is a kind of magnet. The difference from the magnets we usually see is that it is called the "magnet king" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. As a kind of rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force, and has the advantages of high energy density. NdFeB permanent magnet materials have been widely used in modern industry and electronic technology, thus making it possible to miniaturize, lighten and thin equipment such as instruments and meters, electroacoustic motors, and magnetic separation and magnetization. [0003] At present, since ...

AI Technical Summary

Problems solved by technology

[0003] At present, since the surface treatment of rare earth NdFeB blanks is processed by grinding or cutting, a lot of NdFeB debris will be generated during the working process. At this time, it is necessary to use a recycling device to recycle the debris to prevent it The removal of swarf leads to waste of resources. When the existing rare earth NdFeB blank surface treatment recovery device recovers swarf, the recovery rate is not good, which will cause waste of NdFeB resources.

The grinding or cutting process also requires coolant, and often the coolant only needs one service life, resulting in a great waste
