梯度磁场中磁性矿粒所受磁力及影响因素

摘要

考虑实际磁选设备中外部磁场常有梯度，并且磁场梯度方向常与磁场方向不一致的情况，推导出了磁性矿粒所受磁力公式，分析了影响磁力的因素。%In view of the fact that there is often a gradient in the external magnetic field in true magnetic separation equipment,and its direction is often not identical with that of magnetic field,a formula of the magnetic force exerting on the magnetic particles is deduced and the factors influencing the magnetic force are analysed.
