CTB、CTN、CTS型單筒濕式永磁筒式磁選機
Wet permanent magnetic drum separator

國家行業標準JB/T7895

該機主要用于弱磁場濕式選別或除去細顆粒的強磁性礦物，廣泛用于選礦，洗煤和化工等行業，如：回收重介質選礦中的磁性重介質如重劑；鐵選礦中低濃渡礦漿的濃縮和磁鐵礦物的富集；處理強磁選機的給礦，清除其中的磁性或較弱磁性礦物及其連生體，防止磁介質堵塞。

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.

在濕式磁選作業中，若要求獲得純凈的磁性礦物，通常選用順流型磁選機。此時，磁性礦物的回收率有可能會降低；若要求****限度地回收磁性礦物，則選用逆流型磁選機。此時，磁性礦物的品位有可能會降低。當要兼顧磁性礦物的品位和回收率時，以選用半逆流磁選機較為適宜。

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.
