CTB(N. S)系列永磁筒 式磁选机磁场分旋转式、固定式两种机构，固定式主要适用于弱磁场湿式选别细颗粒的强磁性物质，或者除去非磁性矿物中的强磁性矿物，当浆流入磁场区时,其中强磁性矿物被吸附在圆筒表面,弱磁性和非磁性矿物被分选后排除，而吸附在圆筒表面的强磁性矿物随圆简的旋转被带出磁场区。旋转式适用于细粒强(中强)磁性矿物的干选，由于高速旋转的作用，使磁性颗粒的磁滚翻次数大大高于普通磁选机,这对于破坏磁团聚,提高富矿比具有显著的效果，矿物经分选后被分离成磁性物和非磁性物两种，分别从各自的排矿口排除该机适用于矿石粒度为6 - 0mm的粗选和精选。

CTB (n. S) series permanent magnet drum magnetic separator magnetic field, rotating and stationary two mechanism with fixed is mainly suitable for weak magnetic field wet fine particles of strong magnetic material, or in addition to without the powerful magnetic minerals, magnetic minerals when slurry into the magnetic field area, including strong magnetic mineral was adsorbed on the surface of cylinder, weak magnetic and non-magnetic minerals were ruled out after sorting, The strongly magnetic minerals adsorbed on the surface of the cylinder are taken out of the magnetic field with the rotation of the cylinder. Rotation type is suitable for fine strong (medium strong) magnetic mineral dry separation, due to the role of high speed rotation, so that the magnetic particle magnetic roll number is much higher than the ordinary magnetic separator, which for the destruction of magnetic agglomeration, improve the rich ore ratio has a significant effect, the mineral after separation is separated into magnetic and non-magnetic two kinds, The machine is suitable for roughing and cleaning the ore with a particle size of 6-0mm.
