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 concentrate.

The magnetic separator may stabilized ore pulp density and obtain high recovery as the density of feeding ore pulp changes greatly.
