永磁磁选技术的新进展

随着ＮｄＦｅＢ永磁材料的问世及高性能磁性材料的涌现，永磁磁选技术有了很大进展。２主要研究和生产的有永磁辊式磁选机、圆筒型永磁磁选机和永磁高梯度磁选机三种机型，其中圆筒型永磁中强磁场磁选机设备简单，分选指标好，具有很好的推广应用价值。

New Advance of Permanent Magnetic Separation Technology

With the advent of NdFeB permanent magnetic material and the emergence of various magnetic materials with high performances,the permanent magnetic separation technology has achieved great advances.The roll permanent magnetic separator,the drum permanent magnetic separator and the high gradient permanent magnetic separator are the three main types that are at present studied and manufactured.Among them,the medium intensity drum permanentmagnetic separator which is characterised by simplicity and good separation performances has very good values of popularized application.
