永磁高梯度磁选机是随着永磁材料和强磁选机的发展于近二十年来出现的新型高梯度磁选机,其基本原理是利用永磁体产生的背景磁场和聚磁介质产生的磁场梯度力来捕捉微细粒弱磁性矿物。本文介绍了目前永磁高梯度磁选机的发展现状;同时分析指出其存在的问题和发展趋势,并对永磁高梯度磁选机的研究方向提出了几点建议。
Permanent magnetic high gradient magnetic separator is a new type of high gradient magnetic separator which has appeared in recent 20 years with the development of permanent magnetic materials and strong magnetic separators. Its basic principle is to use the background magnetic field produced by permanent magnets and the magnetic field Magnetic field gradient force to capture the fine grain weak magnetic minerals. This paper introduces the current development of permanent magnet high gradient magnetic separator. At the same time, it points out its existing problems and development trend, and puts forward some suggestions on the research direction of permanent magnet high gradient magnetic separator.
