Multi-pole Wet Permanent Magnetic Drum Separator for Coal Mine
Using new magnetic structure,we developed the Multi-pole wet
Permanent Magnetic Drum Separator high-performance permanent magnet
NdFeB and ferrite magnetic source as the main component of complex
magnetic systems, with magnetic field Strong, automatically
removing iron, high rate of iron removing, simple operation, small
amount of maintenance, use of safe and reliable. The weight reduces
30% compared to ordinary ferrite magnetic separator, with the
cylinder surface magnetic field 150-600mT, widely used in various
types of iron ore, gold ore sorting and reconcentration of
tailings. Besides, for other powder materials (such as quartz sand,
etc.) removing the magnetic impurities and magnetic materials
purification. To achieve the concentrating and sweeping operation
can be more than one single series or in parallel to increase
quality or yield.
It mainly consists of magnetic , drum, separation trough, gearing,
and feeding , discharging ,and overflowing device.
According to the different specific susceptibility, it makes use of
magnetic force to separating the various minerals. When the pulp
ores enter into separation area, the strong magnetic minerals will
be absorbed on the surface of the drum under the force of the
magnetic fields, and then be leaded into the Concentrates mouth
along the rotary of the drum. As been away of the magnetic system,
it will be discharged into concentrated trunk by the water, At the
same time, the matrix and the weak magnetic minerals will inflow
the tailings discharging mouth against the rotation direction of
the cylinder, under the flow of the pulp ore in the tank
This magnetic separator is characterized by high recovery of strong
magnetic minerals, large capacity and obvious thickening effect.
Recovery of magnetic iron may reach above 99.5% and density may
reach 50%~65% as feeding density is 20%~25%.
Conventional dewatering tank and thickening pond occupying large
area can be replaced by NCT thickening magnetic separator in
thickening operation of strong magnetic minerals.
Through optimization design, magnetic system angle of the magnetic
separator is large and the magnetic force distribution is more
rational, resulting in a large beneficiation space on small drum,
so that a lot of magnetic concentrate may pass through and valuable
minerals may be recovered as more as possible.
The magnetic separator unloads ore by a scraper in a non-magnetic
zone. It is equipped with a washing pipe for concentrate and water
amount may be adjusted so as to assure suitable density of the
The magnetic separator may stabilized ore pulp density and obtain
high recovery as the density of feeding ore pulp changes greatly.
