磁系的重要性

磁系可以说是除铁机的命脉，决定着除铁机的磁场强度、工作能力和工作效果，所以一台优质的除铁机必须拥有完善的磁系系统，这是必选项。各个除铁机厂家也将磁系的设计作为设计工作的重中之重。

The magnetic system can be said to be the lifeline of the iron removal machine, which determines the magnetic field strength, work ability and work effect of the iron removal machine. In addition to the various manufacturers will also be magnetic system design as the design of the top priority.

一般来讲，若以提高精矿品位为目的，则应该适当增加磁极数即增加磁性物质在分选区的翻转次数;若以提高回收率为目的，则是保证一定品位的前提下适当减小磁极数，增加磁场强度和作用深度，增大磁包角来保证铁磁性物质的充分回收，同时要减小圆周方向磁场梯度，保证吸附矿物的顺利排出。

Generally speaking, in terms of improving concentrate grade should be appropriate for the purpose of increasing the number of poles is increased turnover of magnetic material in the separation region of the times; in terms of improving the recovery rate for the purpose is to ensure the premise of a certain grade under appropriate to reduce the number of poles, and the magnetic field strength increasing depth, increasing the magnetic angle to ensure the full recovery of iron magnetic material, at the same time to reduce the magnetic field gradient in circumferential direction, to ensure the smooth discharge of mineral adsorption.

近年来我国除铁机的研制进展很快，磁选设备的磁系设计是关键，了解磁选设备分选空间的磁场分布十分重要，它对分析磁选设备的性能，进而确定适宜的磁系结构参数、磁块形状和尺寸，以及研究磁性颗粒受力情况起着重要作用。

In recent years China's progress in preparation of iron machine is very fast, the magnetic system of magnetic separation equipment is the key to understand the magnetic separator separation of space magnetic field distribution is very important, it analysis of the magnetic separation equipment performance, and to determine the magnetic structure parameters, the suitable magnetic block shape and size, and study the force of the magnetic particles from an important role.
