Specifically, the principle of the above-described construction method is explained in further detail:
firstly, placing the magnetic aggregate in a composite force field of magnetic force, heavy force and exciting force, so that the direction of the magnetic force applied to the magnetic aggregate is opposite to the direction of self gravity; then, an excitation force which is far larger than the self gravity of the magnet and is opposite to the gravity direction is instantaneously applied to the excitation body (the magnet generating the magnetic field), so that the excitation body generates upward micro-amplitude motion; the exciting force is cancelled instantly when the exciting body moves to the topmost end in a micro amplitude manner, the exciting body rapidly drops in a micro amplitude manner under the action of self gravity, and when the exciting body drops to the bottommost end of the amplitude of micro amplitude vibration, the exciting force is started again.

The excitation bodies are uniformly distributed along the circumferential direction of the inner wall of the rotary roller. The excitation body can also be arranged in a fan shape and corresponds to the lower part of the rotary roller, the upper part of the excitation body is connected with the rotating shaft through a bearing, and the excitation body is always kept at the lower part by utilizing the gravity action of the excitation body, so that the excitation body cannot rotate along with the rotary roller and the rotating shaft.

Any one of the above may be used, and two kinds may be used.
The following detailed description is made on the structures of the coarse magnetic mineral magnetic gravity creep magnetic separation equipment and the coarse magnetic mineral magnetic gravity creep magnetic system: the magnetic systems are uniformly distributed along the bottom of the circumference and symmetrically distributed along two sides of the vertical direction, the wrap angle of the magnetic systems is less than or equal to 180 degrees and the magnetic systems are arranged on the central axis of the circumference; a rotary roller concentric with the circumference is arranged outside the magnetic system, and a certain gap is reserved between the rotary roller and the magnetic system; one end of the rotary roller is provided with a transmission mechanism and a motor reducer for driving the roller to rotate, and the motor, the reducer and the transmission mechanism are fixed on the base station together with the shaft end bearing seat; the lower part of the base station is connected with an elastic element and fixed on a supporting seat of the equipment rack, and the bottom of the base station is also fixed with a high-frequency oscillation motor; the first lateral part of rotatory roller is the concentrate storehouse, and the second lateral part is provided with the hopper that corresponds with the feed storehouse, and rotatory roller bottom is equipped with the tailing storehouse, and hopper, concentrate storehouse, tailing storehouse welded fastening are in the equipment frame.
Introduce high frequency slight amplitude vibration in the vertical radial direction of rotatory roller, under the magnetic force effect, the magnetism thing can vibrate from top to bottom along with the roller is synchronous, but because the non-magnetism thing does not receive magnetic force to influence, when the magnetic agglomeration body upwards vibrates and rises, the non-magnetism thing that is mingled with in the magnetic agglomeration body is under self gravity and inertial action, the instantaneous outside extrusion to the magnetic agglomeration body, and then inside the magnetic agglomeration body that is close to magnetic roller one side has produced small clearance, the strong magnetism mineral that is located around the clearance is under the effect in magnetic field, the clearance packing that will produce in the twinkling of an eye. Under the effect of continuous high-frequency micro-amplitude magnetic vibration, gaps inside the magnetic aggregate are continuously generated and are also continuously filled with strong magnetic minerals, so that the non-magnetic minerals gradually creep away from the surface of the magnetic roller, finally creep from the inside of the magnetic aggregate to the outer surface of the magnetic aggregate, and fall away from the magnetic aggregate under the action of self gravity to enter a tailing bin.
The strong magnetic minerals gradually fill the gaps and enter the inner side of the magnetic roller, and the weak magnetic intergrowth minerals are gradually extruded in the gap filling process and move to the outer side of the magnetic aggregate under the action of the peristaltic effect because the magnetic force applied to the weak magnetic intergrowth minerals is smaller than that of the magnetite monomers in the gap filling process. Therefore, the invention effectively solves the problem of the conventional magnetic separation of mixed nonmagnetic minerals, and simultaneously forms the lamination of magnetite monomers and the intergrowth on the surface of the magnetic roller from inside to outside, namely the magnetite monomer with the strongest magnetism is positioned on the surface of the magnetic roller, and the intergrowth mineral with the weakest magnetism is positioned on the outer side of the magnetic aggregate.
Fig. 4 is a schematic diagram showing the force applied to the non-magnetic material in the magnetic aggregate. The non-magnetic substance wrapped inside the magnetic aggregate is difficult to break through the tight wrapping of the magnetic force generated by the magnetic substance under the action of the magnetic field, so that the non-magnetic substance easily enters the concentrate along with the magnetic substance to influence the quality of the concentrate. F1 is reasonable in gravity and pressure, F2 is the resultant force of wrapping force, in a static state, in the vertical direction, the magnetic wrapping resultant force borne by the nonmagnetic object mixed in the magnetic aggregate is balanced with the resultant force of gravity and the pressure of the inner side mineral to the nonmagnetic object, and the nonmagnetic object in the magnetic aggregate is stationary in the vertical direction. Therefore, the non-magnetic substance in this state is difficult to overcome the wrapping effect of the magnetic agglomerates and is separated from the magnetic agglomerates.
As shown in FIG. 5, the invention introduces magnetic excitation in the vertical direction, which is equivalent to applying a force opposite to the gravity direction on the magnetic aggregate instantaneously, the magnetic aggregate moves upwards instantaneously under the action of the excitation force, and the non-magnetic substance keeps a static state instantaneously under the action of the self inertia, so that a tiny gap is generated instantaneously on one side of the non-magnetic substance close to the upper end roller, and the non-magnetic substance is instantaneously filled with the surrounding magnetic substance. In addition, the magnetic excitation action in the invention loosens the original magnetic aggregate with larger volume instantly, and the resistance of the non-magnetic substance wrapped in the magnetic aggregate to creep outside the magnetic aggregate is greatly reduced.
FIG. 5 is a schematic view showing a minute gap between the upper part of the nonmagnetic object and the magnetic object at the moment of excitation. At the moment of excitation, the static state of an exciting body and a magnetic object on the upper part of the non-magnetic object is broken instantaneously and moves upwards suddenly in a very short time, so that the pressure counter force applied by the roller on the upper part and the magnetic object to the non-magnetic object is reduced or even disappears instantaneously, a loose tiny gap is generated, then, at the very short moment, the magnetic object around the non-magnetic object moves upwards under the action of magnetic force, the generated gap is filled instantaneously, the distance between the non-magnetic object and a fixed superposed magnetic system is increased, and the non-magnetic object generates tiny creeping outside the magnetic aggregation packaging body.
As shown in fig. 6, as the excitation is continued, the creep movement shown in fig. 5 is continued, and the nonmagnetic substance gradually creeps toward the outside of the magnetic agglomerate covering body, is finally exposed to the outer surface of the magnetic agglomerate body, and gradually separates from the magnetic agglomerate body, thereby completing the separation of the nonmagnetic substance and the magnetic substance which are mixed in the magnetic agglomerate body. The dynamic process of the whole separation is shown in figure 6.
While the preferred embodiments for carrying out the invention have been described in detail, it should be understood that they have been presented by way of example only, and not limitation as to the scope, applicability, or configuration of the invention in any way.
