摘要: 为研究高梯度磁选机磁介质的饱和磁化强度对磁介质聚磁性能的影响,进而为高梯度磁选机磁介质材料的选择提供理论依据,利用ANSYS软件模拟了不同背景磁场下4种饱和磁化强度的磁介质周围的磁场分布。结果表明:在小于0.8T的较低背景磁感应强度下,4种磁介质都未达到磁饱和,其周围的磁场强度、磁场梯度和磁场力基本是一样的;在大于1.1 T的较高背景磁感应强度下,4种磁介质都达到磁饱和,高饱和磁化强度磁介质周围的磁场强度、磁场梯度和磁场力都要比低饱和磁化强度磁介质周围的大。

Abstract: In order to study the effect of the saturation magnetization of magnetic matrices in high gradient magnetic separator on the magnetism gathering performance so as to provide a theoretical basis for selecting the magnetic dielectric materials for high gradient magnetic separator,ANSYS software is used to simulate the magnetic field distribution of 4 kinds of saturation magnetization with different backgrounds around the magnetic matrices. The results show that: Under the lower background magnetic field than 0.8 T,the four kinds of matrices haven't reach their magnetic saturation,and the magnetic field strength,magnetic field gradient and magnetic force generated by the matrices are substantially the same; When the background magnetic field is higher than 1.1 T,the four kinds of matrices reach the magnetic saturation,the magnetic field strength,magnetic field gradient and magnetic force generated by the matrices with high saturation magnetization is greater than that with low saturation magnetization.
