CGSL系列试验室立环脉动高梯度磁选机（以下简称CGSL磁选机），适应于1.3毫米(-200目占30～100%)的细粒氧化铁矿（赤铁矿、褐铁矿、菱铁矿等）、锰矿、钛铁矿、黑钨矿等多种弱磁性金属矿的湿式分选和黑白钨分离、黑钨与锡石分离，也可用于非金属矿如石英、长石、霞石矿的除铁等方面。其转环立式转动，反冲精矿，并配有脉动机构。它具有富集比大、分选效率高、不易堵塞、对给矿粒度、浓度和品位的波动适应性强、工作可靠，操作维护方便等优点。

Laboratory CGSL vertical ring pulsation  high gradient electromagnetic separator (“CGSL electromagnetic separator” for short)  is used for wet separation of various weakly magnetic metal minerals such as  finely grinded oxidized iron ores (such as hematite, limonite, siderite),  manganese ores, titanic iron ores, and wolframite with the size of 1.3mm (those with 200 meshes account for 30%  to 100%), as well as the separation of wolframite from scheelite, as well as  separation of wolframite from cassiterite. It is also used to the deironing of  nonmetallic ores such as quartz, feldspar, and nepheline ores. Its swivel  rotates vertically, recoils concentrate, and is equipped with pulsing  mechanism. It enjoys advantages such as big concentration ratio, high  separation efficiency, no easy blockage, strong adaptability to the fluctuation  of granular size, concentration, and grade of feeding ores, reliable operation,  and easy operation and maintenance.

CGSL立环脉动高梯度磁选机从根本上解决了平环强磁选机和平环高梯度磁选机磁介质容易堵塞这一世界性技术难题，它具有富集比大、对给矿粒度、浓度和品位波动适应性强、工作可靠、操作维护方便等优点，该机分选弱磁性矿石实现了精矿品位高和回收率高的双高优点。

CGSL  electromagnetic separator fundamentally solves the worldwide technical problem  that blockage often occurs in horizontal ring high intensity magnetic  separators and horizontal ring high gradient magnetic separators. It enjoys  advantages such as big concentration ratio, strong adaptability to the fluctuation of granular  size, concentration, and grade of feeding ores, reliable operation, and easy  operation and maintenance. Such machine realizes both high concentrate grade  and high recovery rate during the separation of feebly magnetic minerals.

CGSL磁选机采用转环立式旋转方式，对于每一组磁介质而言，冲洗精矿的方向与给矿方向相反，粗颗粒不必穿过磁介质堆便可冲洗出来，从而有效地防止了磁介质堵塞。

CGSL  electromagnetic separator adopts the rotation method of vertical rotation of  swivel. For every group of magnetic medium, the direction of concentrate  flushing is opposite to the direction of ore feeding. The coarse grains can be  flushed without passing the magnetic media, so as to effectively prevent  blockage of magnetic media.

设置矿浆脉动机构，驱动矿浆产生脉动流体力。在脉动流体力的作用下，矿浆中的矿粒始终处于松散状态，可提高磁性精矿的质量。

Mount slurry  pulsation mechanism to drive the slurry to produce pulstation fluid dynamics.  Under the action of pulsation fluid dynamics, the ore grains in the slurry is  always under a loose conditions so that the quality of magnetic concentrate can  be improved.

平环高梯度磁选机对给矿粒度要求比较严格，我们研究了独特磁系结构及优化组合的磁介质，使 CGSL磁选机给矿粒度上限达到2.0毫米，简化了现场分级作业，具有更为广泛的适应性。

The  horizontal ring high gradient magnetic separators have strict requirements for  the granular size of feeding ore. We have studied the magnetic media with  unique magnetic structure and optimum composition.
