近年来,作者们看到中场强磁选机的需要日益增长,这些磁选机用来处理风化的假像赤铁矿矿石、中等磁性矿石以及从原生及次生工业矿物中脱除中等磁性杂质。在新型永磁材料方面亦获得显著进展,如钐钴材料(Sm Co,及钕铁硼材料(NdFeB)。研究涉及磁场强度、磁场梯度及工作深度。在这方面,KHD洪堡威达格公司研制的NdFeB永磁铁的新磁场磁结构(置于PERMOS鼓式兹选机内),现已用于工业。PERMOS兹选机内部的兹系已不再是由较大磁块构成,这些大磁块是在放射状结构中交替磁化的。现在的磁系由许多小磁棒构成,其磁化方向的变化可少量增值。本文介绍了PERMOS OGMS型干式及湿式磁选机的设计持点,及其研究的主要优点。
In recent years, the authors have seen a growing need for mid-field ferromagnetic separators used to treat weathered hemichemite hematite, medium magnetic ores, as well as removal of moderate magnetic properties from primary and secondary industrial minerals Impurities. Significant progress has also been made on new permanent magnet materials, such as SmCo and NdFeB materials. The study involved magnetic field strength, magnetic field gradient and working depth. In this regard, KHD Humboldt & The new magnetic field structure of the developed NdFeB permanent magnet, placed in the PERMOS Drum, is now used in industry. The internal system of the PERMOS magnetic separator is no longer made of larger magnets, The blocks are alternately magnetized in a radial structure, and today’s magnetic system is made up of many small magnet bars with small changes in the magnetization direction.This article describes the design points for PERMOS OGMS dry and wet magnetic separators, and their The main advantage of the study.
