Product Application:

  • To be applied to the dry preconcentration of high-grade and lean magnetite ore before grinding with the selected granularity below 30mm. The finer the granularity is, the better the result is. Generally, large amount of tailings can be discharged, and the grinding quality can be greatly enhanced. To be applied to dry separation and recycling of the lost magnetite from the abandoned tailings. To be applied to dry separation and recycling of ferromagnetic materials from the abandoned steel slag.
  • As shown in the figure, the separation cylinder without belt outside will enhance the intensity of magnetic field of the separation area. The rotating magnetic system (wrap angle of 360 degree) is set inside the separation cylinder, while the fixed magnetic system (magnetic wrapping angle of less than 90 degree) is set inside the ore dumping cylinder. The rotation direction of the separation cylinder is as the same as that of the ore dumping, but is opposite to that of the rotating magnetic system.
  • When the materials feeder transports the minerals to the separation area of the separation cylinder, 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.
  • In the separation area of the separation cylinder, the centrifugal force and gravitation of magnetic minerals mingled with non-magnetic minerals are much less than the magnetic force. 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 cylinder, 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.

Product Features:

  • 1, This patented product is a kind of upgrading equipment based on conventional magnetic roller or conventional dry separator. When it is working, the magnetic minerals will take rapid magnetic reversal and magnetic agitation, which will significantly reduce the number of non-magnetic (weak magnetic) minerals in the magnetic minerals. In this way, 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, This patented product solves the eddy current heating problem, ore sticking problem for separation cylinder, and mine unloading problem of conventional 360 degree rotating magnetic dry separator. The conventional 360 degree rotating magnetic dry separator must use the belt to unload the mine by the outside of it, therefore the magnetic minerals are easy to enter the central space between the inside belt and sorting tank. The magnetic minerals attached on the surface of sorting tank cannot fall off automatically (cannot unload mine automatically). As the accumulation grows, the separation effect is affected. Whats worse, rapid wear of sorting tank body as well as the belt will be caused, and the normal operation of production will be seriously affected.
  • 3, Under the condition that the grade of the dry tailings is equal to or even lower than that of conventional magnetic roller or conventional dry separator, for high-grade and lean magnetite with different features, by adjusting corresponding technical parameters and structure, about 10%-30% tailings discharging and about 1.0%-8.7% of concentration grade can be increased compared to conventional magnetic roller or conventional dry separator. The concentrate grade of dry separation is significantly enhanced compared to the feeding grade. Under the conditions of fine crushing size of below 2 mm and coarse dissemination size, more than 60% grade of the dry separation concentrate can usually be obtained directly. In the actual production, if one p
