圆筒型三相交流磁选机去除耐火材料中铁杂质的研究

EXPERIMENTAL STUDY ON REMOVAL OF IRON IN REFRACTORY BY THREE_PHASE A C MAGNETIC SEPARATOR

三相交流磁选机具有磁系不动而磁场旋转移动的特点，结构简单，适合于处理铁杂质含量少的细粒级物料（如耐火原料中的混入铁）．用圆筒型三相交流磁选机对耐火原料进行除铁试验的研究，探讨了影响除铁效果的因素及提高除铁率的方法．

Rotating and moving magnetic field as well as simple structure are primary characteristics of three_phase alternating current magnetic separator. This apparatus is suitable for processing materials containing a little amount of fine magnetic impurities (for example iron filling in raw refractory material). The results of iron removal experiment and the removing method are discussed in this paper.
