摘要:
当励磁电流为200 A时,计算了周期式高梯度磁选机线圈轴线轴向和距轴线0.15 m处径向的磁感应强度,并运用ANSYS有限元分析软件分析了屏蔽铁铠和磁极对线圈磁场特性的影响,同时采用该设备进行了高岭土磁分离除铁实验. 结果表明,距线圈中心0.1 m轴线轴向为0.326 T的均匀磁场,随着与中心距离的增加磁感应强度大幅下降;距轴线0.15 m径向的磁感应强度很小,在端面效应的作用下达到最大值0.064 T;安装屏蔽铁铠和磁极,线圈中心均匀磁场的磁感应强度提高至0.95 T. 在矿浆流速为0.7 cm/s,背景磁感应强度为1.1 T下,一次磁选将高岭土的Fe2O3的质量分数由1.35%降至0.63%,白度由68%提高至89%.
Abstract:
Magnetic induction intensity of the radial axis and 0.15 m from the axis of the coil in periodic high gradient magnetic separator were calculated at an excitation current of 200 A. The influences of shielded iron armor on magnetic field characteristics of the coil were analyzed by ANSYS finite element analysis software as well. Simultaneously, kaolin magnetic separation and iron removal experiment were carried out. The results showed that axial magnetic induction intensity around 0.1 m of the coil center was in a uniform magnetic field of 0.326 T, and the magnetic induction decreased significantly with the distance from center increasing. The magnetic induction of the site of 0.15 m around the axis was very small in the radial direction, and the maximum value of that was 0.064 T by the end effect. The magnetic induction of the uniform magnetic field in the coil center might increase to 0.95 T after an armored iron and a magnetic pole in the solenoid coil were installed. When the background magnetic induction intensity was 1.1 T at pulp flow rate of 0.7 cm/s, the mass fraction of Fe2O3 in kaolin reduced from 1.35% to 0.63%, and the whiteness of it increased from 68% to 89% by one magnetic separation only.
