Efficient Mining Equipment Mineral Processing Equipment Dry Drum Magnetic Separator Magnetic Separator

Dry drum magnetic separators are the perfect choice for the recovery of iron ore in dry areas such as Chile, Mongolia, the Southwest of the US, the Northwest region of China and many other dry or desert areas. The application of a dry drum separator lowers the beneficiation plants reliance on water and is environmental friendly. Depending on the magnetic intensity needed the magnet system can be either ferrite or rare earth.

Features and technology advantages

1.The efficient separation of magnetic minerals and non-magnetic (weak magnetic) minerals will be realized, and fine magnetic minerals and coarse magnetic minerals will not get lost.

2.Covering the magnetic system with non-magnetic stainless steel ensures no peeling off of the magnet.

3.The drum is covered with the super wear-resistant rubber produced by our company, thus the service life can be prolonged significantly.

Working principle

When the materials feeder transports the minerals to the separation area of the separation drum, the magnetic minerals will alternate rapidly and repeatedly within a short time through the N pole and S pole of the magnetic field, and the magnetic minerals will do magnetic rever­sal and magnetic agitation. The non-magnetic (weak) magnetic mineral mingled in the magnetic minerals is not or slightly affected by the adsorption of the magnetic force, moving to the outer layer gradually, and is thrown out by the centrifugal force, gravity and the joint action of magnetic turn and agitation of magnetic minerals. With the adsorption of the magnetic force and the joint action of the magnetic turn and agitation of magnetic minerals, the mag­netic minerals will move to the inter layer gradually. When the magnetic minerals rotate to the ore unloading area with the separation drum, as the rotation magnetic system is eccentric, the magnetic density of the ore unloading area for the separation cylinder is extremely weak, and most of the magnetic minerals can fall off automatically. A small quantity of magnetic minerals not falling off will be adsorbed to the external surface of the ore unloading cylinder with higher magnetic density when rotating to the position nearby the ore unloading cylinder so as to realize the automatic unloading of magnetic minerals.
