Description
Technical field
The utility model relates to the equipment of metal in a kind of magnetic separation breeze, is particularly suitable for the equipment of ferrous metal in magnetic separation Iron Ore Powder or the iron ore powdered tailings.
Background technology
Iron ore comprises the kinds such as the silicate ore of magnetic iron ore, hematite, limonite ore, siderite, iron and iron sulfide ore.In the prior art, after the method for processing iron ore usually adopts iron ore is pulverized again the mode through flotation or magnetic separation improve its grade, and usually be referred to as mine tailing through the leftover materials that flotation or magnetic separation were processed.Although the content of non-metallic particle such as silica is more in the mine tailing, but metallic particles content is less in it, so mine tailing is not suitable for directly as producing slag cement and crystal glass, and the raw material of construction material, must be through just being utilized behind the separating ferrum metal.
Usually adopt magnetic method to come the separating metal particle in the prior art, the magnetic method ore dressing comprises wet magnetic separation and dry type magnetic separation dual mode.Wherein, when utilizing the ore dressing of wet magnetic separation method or mine tailing, need a large amount of water that breeze or mine tailing are diluted to form ore pulp, and then through magnetic separator ore pulp is carried out magnetic separation, to select magnetic material, but because a large amount of water resources is not only wasted in the ore dressing of wet magnetic separation method, and also can cause environmental pollution.Particularly the interior contained metallic particles of mine tailing is less, and water consumption is larger, and environmental pollution is even more serious, and the rate of recovery of iron powder is also lower.The dry type magnetic separation method is separated the magnetic separator of magnetic material, generally includes drier and feed mechanism, and the magnetic separation mechanism that is used for receiving feed mechanism institute convey materials.Its operation principle mainly is to carry out sorting with being transported to magnetic separation mechanism by feed mechanism after the breeze drying first, is adsorbed on the cylinder of magnetic separation mechanism by high-intensity magnetic field with the particle with magnetic.Although the dry type magnetic separation method can conserve water, and the degree of environmental pollution is relatively poor, because no matter drier adopts electric energy or coal, its energy that consumes is quite large, and the magnetic separation cost is very high; And feed mechanism adopts the plant equipment such as ribbon conveyer or forklift usually, and the mode of this conveying mine tailing can not realize disperseing and carrying equably, causing magnetic separator must produce large gravitation could inhale clothes on cylinder with magnetic material, and then consumes a large amount of magnetic energy; Simultaneously, the cylinder of this magnetic separator takes metalliferous material by rotating to inhale, and the size of cylinder and magnetic pull determines to separate in the unit interval quantity, want to improve the efficiency of separation, can only increase volume and the magnetic pull of cylinder, so the operating efficiency of this kind magnetic separator is directly proportional with energy consumption.
Summary of the invention
The purpose of this utility model provide a kind of utilize wind-force to dispel that mode that breeze or mine tailing carry out magnetic separation again solves environmental pollution and efficiency of magnetic separation is low and the magnetic separation breeze of high in cost of production problem in the equipment of metal.
