磁系可以說是除鐵機的命脈，決定著除鐵機的磁場強度、工作能力和工作效果，所以一臺優(yōu)質的除鐵機必須擁有完善的磁系系統(tǒng)，這是必選項。各個除鐵機廠家也將磁系的設計作為設計工作的重中之重。

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.

一般來講，若以提高精礦品位為目的，則應該適當增加磁極數即增加磁性物質在分選區(qū)的翻轉次數;若以提高回收率為目的，則是保證一定品位的前提下適當減小磁極數，增加磁場強度和作用深度，增大磁包角來保證鐵磁性物質的充分回收，同時要減小圓周方向磁場梯度，保證吸附礦物的順利排出。

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.

近年來我國除鐵機的研制進展很快，磁選設備的磁系設計是關鍵，了解磁選設備分選空間的磁場分布十分重要，它對分析磁選設備的性能，進而確定適宜的磁系結構參數、磁塊形狀和尺寸，以及研究磁性顆粒受力情況起著重要作用。

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.
