QJ-NCT permanent-magnet concentrating separator is a newly developed magnetic separator especially designed for adjusting concentration of magnetic ore at the upstream and downstream sections of the addressing plant. Its best features are high recovery rate, large treatment capacity and very effective concentration for minerals of strong magnetism. When the concentration of fed ore is 20%-25%, the armco-iron recovery rate can reach 99.5% or more and concentration can reach 50%-65%. This machine can completely replace space-occupying dewatering tanks and concentration basins in concentrating treatment of ores with strong magnetism.

       Through optimized design, the magnetic system of the machine has a wide wrapping angle and the magnetic force is more reasonably distributed, allowing smaller drum having larger separating space to let large amount of magnetite concentrates pass and prevent usable ore from running off. This separator discharges ore with non-magnetic-zone scrappers assisted by flushing pipes with adjustable flowrate, to ensure desirable concentration rate of the ore.

       For ore addressing plants with big fluctuations in the concentration of raw ore slurry, relatively stable concentration and high recovery rate can also be reached using this separator.
