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立環(huán)脈動(dòng)高梯度磁選機(jī)從根本上解決了平環(huán)強(qiáng)磁選機(jī)和平環(huán)高梯度磁選機(jī)磁介質(zhì)容易堵塞這一世界性技術(shù)難題，它具有富集比大、對(duì)給礦粒度、濃度和品位波動(dòng)適應(yīng)性強(qiáng)、工作可靠、操作維護(hù)方便等優(yōu)點(diǎn)，該機(jī)分選弱磁性礦石實(shí)現(xiàn)了精礦品位高和回收率高的雙高優(yōu)點(diǎn)。

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磁選機(jī)采用轉(zhuǎn)環(huán)立式旋轉(zhuǎn)方式，對(duì)于每一組磁介質(zhì)而言，沖洗精礦的方向與給礦方向相反，粗顆粒不必穿過磁介質(zhì)堆便可沖洗出來，從而有效地防止了磁介質(zhì)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.

設(shè)置礦漿脈動(dòng)機(jī)構(gòu)，驅(qū)動(dòng)礦漿產(chǎn)生脈動(dòng)流體力。在脈動(dòng)流體力的作用下，礦漿中的礦粒始終處于松散狀態(tài)，可提高磁性精礦的質(zhì)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.

平環(huán)高梯度磁選機(jī)對(duì)給礦粒度要求比較嚴(yán)格，我們研究了獨(dú)特磁系結(jié)構(gòu)及優(yōu)化組合的磁介質(zhì)，使 CGSL磁選機(jī)給礦粒度上限達(dá)到2.0毫米，簡化了現(xiàn)場分級(jí)作業(yè)，具有更為廣泛的適應(yīng)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.
