烧结钕铁硼永磁体机械加工后所产生粉削再生利用处理方法

The recycling method for the powder of the sintered Nd-Fe-B permanent magnets generated from machining

本方法为烧结钕铁硼永磁体机械加工后所产生粉削再生利用的处理方法,涉及烧结钕铁硼永磁体的加工。解决现有化学方法的粉削再生利用处理方法存在的问题。处理后得到的可再生利用的NdFeB合金粉末价格大大低于非再生的原材料价格,从而降低了钕铁硼永磁体的原材料成本。

This method is a recycling method for the powder generated in machining of the sintered Nd-Fe-B permanent magnet. It involves the processing of sintered Nd-Fe-B permanent magnet. It solves the existing problem of the chemical recycling method for the powder generated in machining of the sintered Nd-Fe-B permanent magnet. The price of the recycling alloy powder obtained by this method is significantly lower than the price of raw materials. Thus, it reduces the cost of the raw materials of Nd-Fe-B permanent magnet.
