CTB、CTN、CTS型单筒湿式永磁筒式磁选机
Wet permanent magnetic drum separator

国家行业标准JB/T7895

该机主要用于弱磁场湿式选别或除去细颗粒的强磁性矿物，广泛用于选矿，洗煤和化工等行业，如：回收重介质选矿中的磁性重介质如重剂；铁选矿中低浓渡矿浆的浓缩和磁铁矿物的富集；处理强磁选机的给矿，清除其中的磁性或较弱磁性矿物及其连生体，防止磁介质堵塞。

This type of equipment is mainly used to select wet weak magnetic field and remove the strongly magnetic minerals of fine grains. They are widely used in mineral processing industry, coal washing industry, chemical industry, etc, e.g. recycle heavy formulas such as magnetic heavy media during heavy media separation, concentrate low-concentration slurry in iron ore and gather magnetic steel minerals, treat ore feeding from high-intensity magnetic separators, remove magnetic or weakly magnetic ores and coenobium, as well as prevent blockage of magnetic media.

在湿式磁选作业中，若要求获得纯净的磁性矿物，通常选用顺流型磁选机。此时，磁性矿物的回收率有可能会降低；若要求****限度地回收磁性矿物，则选用逆流型磁选机。此时，磁性矿物的品位有可能会降低。当要兼顾磁性矿物的品位和回收率时，以选用半逆流磁选机较为适宜。

During wet magnetic separation, to get pure magnetic minerals, downstream magnetic separators are usually selected. In such case, the recovery ratio of magnetic minerals might be reduced. If the magnetic minerals are required to be recycled to the largest extent, counter-current magnetic separators shall be selected. In this case, the grade of magnetic minerals might be reduced. If both the grade and recovery rate of magnetic minerals shall be taken into account, semi-countercurrent magnetic separators might be more appropriate.
