所以无论是锶铁氧体磁钢还是钕铁硼磁钢均有必要进行固定。
So whether strontium ferrite magnets or ndfeb magnets are necessary for fixed.
磁选设备中的保养手册有很多，其中磁系中一般采用锶铁氧体磁钢和钕铁硼磁钢。
Magnetic separation equipment's maintenance manuals are many, including magnetic is generally USES strontium ferrite magnets and ndfeb magnets.
其中钕铁硼磁钢化学稳定性较差，在磁滚筒内潮湿的空气中，易出现表面氧化逐步分层剥落的现象。
One ndfeb magnets chemical stability is poorer, in magnetic drum in humid air, easy appear on surface oxidation gradually layered peeling phenomenon.
其中钕铁硼磁钢化学稳定性较差，在磁滚筒内潮湿的空气中，易出现表面氧化逐步分层剥落的现象。
One ndfeb magnets chemical stability is poorer, in magnetic drum in humid air, easy appear on surface oxidation gradually layered peeling phenomenon.
