摘    要:高梯度磁选机是在其他强磁选机的基础上发展起来的一种新型强磁选机。通过整个高梯度磁选机工作体积的磁化场是均匀的,即工作体积中的任何一个颗粒受到的力相同,且磁化场中的磁介质被均匀磁化,同直径的磁介质在磁化空间的任何位置,其梯度的数量级是相同的,与一般磁选机相比较,磁场梯度大大提高,从而为磁性颗粒的选别提供强大的磁力克服流体阻力和重力,使微细粒弱磁性颗粒可以得到有效的回收。高梯度磁选是在能产生高梯度的聚磁介质上进行的,而高梯度的产生与聚磁介质的材质、形状、放置方式、相对尺寸及充填率等参数有密切关系,对磁选机的磁选指标有较大的影响。

关 键 词:高梯度磁选机  聚磁介质  参数  影响

Abstract:High gradient magnetic separator is a new type high-intensity magnetic separator which was developed on the basis of other strong magnetic separator.The magnetic field in the working volume of the high gradient magnetic separator is uniform,which means that any particles was subjected to equal force in the working volume,and the magnetic medium was uniform magnetization in uniform magnetic field.The magnetic medium with the same diameter in any postion of the magnetic space has the same gradient magnitude.ompared with general magnetic separator,the magnetic field gradient was greatly increased,which could provide a powerful magnetic force to overcome the fluid resistance and gravity for sorting of magnetic particles,so that the micro-fine weak-intensity magnetic particles can be effectively recycled.The high gradient magnetic separation is conducted in the magnetic matrices which can produce high gradient,and the generation of the high gradient has a close relation with the material,shape,the way of placement,relative size,filling rate and other parameters of the magnetic matrices,which have a significant influence on the magnetic separation index of the magnetic separator.
Keywords:High gradient magnetic separator  Magnetic matrices  Parameters  Influence
