Description
Technical Field
The invention belongs to the technical field of mineral engineering, relates to equipment for physical ore dressing, and particularly relates to a permanent magnet drum type fine grain magnetic separator which is a magnetic separation device mainly used for sorting according to iron-containing magnetism of ores.
Background
The magnetic separation method is the most widely applied production process for recovering iron ore in metal mines. At present, the recycling of magnetite in metal mines in China mostly adopts a wet magnetic separation method, and the magnetite is usually separated by a permanent magnet drum magnetic separator.
The permanent magnetic drum magnetic separator has 3 structural forms of forward flow type, reverse flow type and semi-reverse flow type according to different working properties. The concurrent magnetic separator is suitable for ores larger than 6 mm; the counter-flow magnetic separator is suitable for ores with the diameter of less than 2-3 mm; the semi-countercurrent magnetic separator is suitable for 0.3mm ores, and only ores with proper grain sizes can be selected in each structural form.
Because the magnetic pole is positioned in the cylinder, the ore pulp passes through the lower part of the outer side of the cylinder, when the magnetic particles are attracted by magnetic force to move towards the cylinder, the magnetic particles overcome the resistance of the ore pulp and the gravity of the magnetic particles, and the magnetic particles with relatively small magnetic attraction are lost in tailings or middlings due to difficult attachment to the cylinder, so that the recovery rate of iron is influenced.
In the process of unloading, because only single row ore discharge water, hardly can fully discharge the product granule, unload the mining area simultaneously also less relatively, these all can influence the yield of product. The prior art has the following problems: (1) In the traditional cylindrical magnetic separator, the magnetic system is arranged in the cylinder, and the ore pulp passes through the lower half part of the surface of the cylinder, so that the direction of magnetic attraction borne by magnetic particles is opposite to that of gravity, and a part of the magnetic particles are difficult to be adsorbed to the surface of the cylinder due to weaker magnetic attraction and are lost in tailings, so that the magnetic particles are difficult to have higher recovery rate; (2) The size of the gap between the barrel and the concentrate discharge part of the traditional barrel magnetic separator is mainly determined according to the production capacity. The clearance is too small, so that the concentrated ore which is sorted is influenced to be discharged; too large a gap will cause a portion of the concentrate that is discharged from the barrel to fall back into the trough, again affecting concentrate discharge. Meanwhile, the retention time of the concentrate in the box body is too long, so that the loss of the concentrate is difficult to avoid. The adjusting range is generally 15-25 mm according to requirements, and the gap of the ore discharging port can be adjusted by moving the chute body back and forth. However, in production, when the properties of ore change, the ore discharge gap of the concentrate is difficult to adjust in time, so that the concentrate is lost.
