磁選柱是一個由外套和多個勵磁線圈組成的分選內筒給排礦裝置及電控柜構成的一種電磁式磁重選設備，它允許的上升水流速度很高，再加向下移動的脈動磁場的作用，從而能高效分出連生體，獲得高品位的磁鐵礦精礦。

Magnetic separation column is a kind of electromagnetic magnetic-gravity separation equipment which is composed of a separation inner tank feeding and discharging device which consists of cover and many exciting coils as well as electrical cabinet. Due to very high increased water flow velocity allowed by it as well as the action of pulsating magnetic field moving downward, it can very effectively separate the coenobium and get high-grade magnetic concentrate.

本實用新型磁選柱，其結構設計合理，與相近的精選磁鐵礦的磁重選設備相比，具有分選精度高，所需相對磨礦粒度粗，精礦作業產率高等特點。由于存在變化的脈沖磁場及相對強大的旋轉上升水流，因此它既能充分破壞次團聚，又能充分利用磁團聚，從而能高效分出連生體，大幅度提高精礦品味，提高作業產率及作業回收率。可用其從磁選中間產品中提前獲取合格品味最終精礦，也可用其精選磁選廠低品味精礦獲得高品位精礦，還可用來精選易選磁鐵礦精礦獲得超級鐵精礦。 

This new practical magnetic separation column is reasonably structured. Compared with similar magnetic-gravity separation equipment of magnetic concentrate, it features high separation accuracy, relatively coarse granular size of required ores, and high productivity of concentrate. Since it has pulsed magnetic field that may change and relatively strong rotating water current that moves upward, it can not only disrupt magnetic agglomeration, but also make full use of magnetic agglomeration, so as to highly effectively separate the coenobium, largely raise the grade of concentrate, and improve the productivity and recovery rate. It can be used to obtain final concentrate of qualified grade in advance from the products being separated; it can be used to carefully select low-grade concentrate in ore dressing plant to obtain high-grade concentrate; and it can also be used to carefully select the concentrate of magnetic iron ore to obtain super iron concentrate.
