在永久磁铁及其磁路设计中,工作点的选择十分重要。本文作者采用长方形锶铁氧体,其磁能积(BH)_(max)=(3.1~3.3)×10~6高斯·奥斯特,对不同长宽比例、不同矫顽力通过实验给出工作点 B_d=f(L/S~(1/S)),以及退磁因子 N=f(L/S~(1/S),a/b)曲线,并通过计算给出各种曲线回归方程式。磁通密度在磁铁中的分布以及在磁铁表面上数值的计算是基本磁路设计,文中采用三种形式进行计算。“日”字型磁系可较大幅度提高永磁磁选设备磁场强度。在总结各种因素对背景场强影响的实验基础上,提出一种较简单的计算方法。文中计算误差基本在10%以内。

我国大中型磁铁矿山中,矿石贫化现象较为普遍,在粗碎后采用大型磁滚筒预选,剔除-350mm大块脉石,使占原矿量10~20%的合格尾矿免除进一步破碎、磨矿及选矿工序,节能节电,经济效益显著。设计大型永磁磁滚筒应考虑与分选大块矿石相适应的磁场特性曲线的分布特点、磁场深度、磁场力等主要因素。CT—1416永磁磁滚筒采用高磁能积的稀土磁钢与铁氧体材料组成复合磁系,为目前工业生产中使用的规格最大、磁场力最强的干式永磁磁滚筒,具有国际先进水平,对混入围岩较多的磁铁矿选矿厂具有广阔的应用前景。
