Problems solved by technology

[0007] Compared with the traditional dry magnetic separator, the above solution has greatly improved the recovery rate of minerals, but there is still the problem that the grade of recovered minerals is not ideal
The reason is that the wind force in the above solution is only used as a conveying force, and the magnetic material only has gravity and vibration force to compete with the magnetic force during the sorting process, and the characteristics of the fine-grained magnetic material make the minerals sorted out There are more packages and inclusions, which cause the problem of unsatisfactory mineral grades

Embodiment 1

[0028] like figure 1 The magnetic system of a vibrating magnetic separator shown mainly includes a non-magnetic air chamber 1 (which can be disc-type, box-type, drum-type or other shapes), magnetic system 2 (permanent magnet or electromagnet, etc.), A vibrating device 3 to vibrate the air chamber 1; the air chamber 1 is closed and an air inlet 4 is set at a suitable position, and the working surface is a ventilating plate 5 with air holes to form an air passage; On the driving part; the magnetic system 2 is fixed in the air cavity 1 through an external support to form a relative translational movement with the air cavity 1. In this embodiment, the magnetic system 2 is fixed, the air cavity 1 translates along the axis, and the movement direction of the air cavity 1 is in line with the The direction of the magnetic force of the magnetic system 2 is vertical and the speed is controllable. The direction of the magnetic force of the magnetic system 2 is opposite to the direction of...

Embodiment 2

[0031] like image 3 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the magnetic system 2 is fixed on the outside of the air cavity 1 opposite to the air-permeable plate 5 through external support, and the magnetic medium 6 is fixed on the air cavity corresponding to the magnetic system 2 1, the rest with figure 1 same. In this optimal solution, the magnetic system 2 is installed outside the air cavity and the magnetic force range is extended through the magnetic medium 6, which not only ensures the sorting effect, but also avoids the sealing between the external support of the magnetic system 2 and the air cavity 1 in solution 1. question.

Embodiment 3

[0033] Figure 4 and Figure 5It is another embodiment of this patent. This embodiment is basically the same as Embodiment 1. The difference is that in this embodiment, the air cavity 1 is a hollow cylinder that rotates around an axis, and the speed is controllable. The cylinder body is equipped with The air-permeable plate 5 with air holes is made, the magnetic system 2 is fixed in the air cavity 1, and forms a relative rotational motion with the rotating air cavity 1, and the air inlet 4 is set on the hollow shaft connected to the air cavity 1 and connected to the pressure gas , Vibration device 3 is located on the shaft. In this embodiment, the material to be selected is conveyed from the bottom of the air cavity 1, and the magnetic material and its packaged inclusions are adsorbed to the working surface of the air-permeable plate 5 under the action of the magnetic system 2, and the non-magnetic material is sent to the tailings mouth. At this time, the materials adsorbed ...

Abstract

The invention discloses a magnetic separation device for a dry magnetic separator and belongs to the field of the dry magnetic separator. The magnetic separation device comprises a non-magnetic closed air cavity provided with an air inlet and a plurality of vent holes, wherein the vent holes are formed in the working face of the air cavity. The magnetic separation device further comprises magnetic systems and a vibration device, wherein the magnetic action force directions of the magnetic systems are opposite to the air outlet direction of the working face of the air cavity, the vibration device is used for vibrating the air cavity, the air cavity moves relative to the magnetic systems, and the moving direction of the air cavity is vertical to the magnetic action force directions of the magnetic systems. According to the magnetic separation device for the dry magnetic separator, the recovery rate and grade of magnetic minerals can be remarkably improved, and the separation force is adjustable.

Description

technical field [0001] The invention belongs to the field of dry magnetic separators, and is suitable for the separation of magnetic minerals after being ground by grinding equipment in industries such as metallurgy, mining, and chemical industry. Finished or semi-finished products can be sorted according to the granulation of materials, especially for those with a diameter of less than 1mm. Sorting of dry mineral powder. Background technique [0002] Using the difference in magnetic properties of mineral particles, sorting in a magnetic field is a commonly used method for magnetic material sorting. Wet magnetic separator needs water as the working medium, which cannot be used in water-deficient areas, and may cause environmental pollution, so it is not worth promoting. Therefore, dry magnetic separation has developed rapidly in recent years. Traditional dry magnetic separators rely on the direct attraction of the magnetic field to capture magnetic mineral particles, but th...
