Description
Technical field
The present invention relates to the magnetic separator of a kind of ore dressing, particularly with, from fluvial sand, ore pulp, selecting iron ore from the mixed liquor of nonmetal fine particle and iron tramp or mixture, reject the dry-and wet-type circulation electromagnetic separator of iron tramp.
Background technology
Magnetic separation is the main beneficiation method processing iron ore.Metallic ore especially iron ore, after ore dressing, improves grade, reduces impurity content, be of value to smelting process.Practice according to China, iron concentrate grade often improves 1%, and the capacity factor of a blast furnace can increase by 2%～3%, and coke consumption amount can reduce by 1.5%, and consumption of limestone amount can reduce 2%.Many non-ferrous metals and the mineral of rare metals have different magnetic.When not obtaining final concentrate with gravity treatment and flotation, available magnetic separation sorts in conjunction with additive method.
Magnetic separation is except the effective grade that can improve metallic ore, moreover it is possible to the harmful iron tramp in nonmetal raw material is rejected, so magnetic separation is one of operation important in nonmetal ore-dressing.Along with raising and the needs of resource regeneration of human environment protection consciousness, magnetic method is widely used in the recovery of slag and old metal and separates and in the process such as sewage disposal.
Now domestic occur in that dry-and wet-type magnetic separator.
Chinese patent 201287070Y discloses a kind of dry wet magnetic separator, and its composition includes frame, crushing mechanism, magnetic separation mechanism and conveying mechanism, and described frame one end is provided with feeding mouth, and the other end is provided with discharging opening；Described crushing mechanism is by fixing roller and adjustable roller forms, and the wheel shaft two ends of described fixing roller and adjustable roller rotationally support in frame；Described magnetic separation mechanism is positioned at below crushing mechanism, its interior magnetic roller set of cylinder and envelope become, uniform permanent magnets on half surface of left magnetic roller, and constituting half has the magnetic half magnetic roller without magnetic；Described conveying mechanism is material-conveying belt, is positioned at cylinder bottom.This utility model, in magnetic separation process, does not completely enclose, and raw material easily causes waste and pollutes when selected and when mineral or residue flow out；And this device often add a defective material can only magnetic separation once, efficiency of magnetic separation is low.
Chinese patent 201132135Y discloses a kind of dry wet magnetic separator, the dry-wet type permanent ferromagnetism ore-separator that this utility model is made up of frame, magnetic roller, dragging roller, conveyer belt, hopper, drive mechanism, water pipe.Before upper magnetic roller, it is provided with rectangular funnel corresponding with magnetic roller size leads ore deposit plate, lead plate two, ore deposit and be movably connected in frame, lead the size scalable leading mine mouth between ore deposit plate and magnetic roller；Rectangular magnetic conductive board corresponding with magnetic roller size it is additionally provided with on lower magnetic roller, it is arranged above with several Kent adjustable magnetic plates at magnetic conductive board, on magnetic conductive board with adjustable magnetic plate, corresponding position has several circular holes, with bolt corresponding with circular hole size, adjustable magnetic plate is fixedly connected on above magnetic conductive board, magnetic conductive board two is movably connected in frame, can move left and right above magnetic conductive board left magnetic roller, forms strong, territory, weak magnetic area；Being provided with again below upper and lower magnetic roller and magnetic roll shape, the corresponding semicircle of size clean ore deposit groove, groove two, clean ore deposit is fixedly connected in frame.At this moment, water pipe supplies water, can as wet-type everlasting strong magnetic ore separator；When clean ore deposit groove is unloaded down frame, water pipe does not supply water, at this moment, and can as dry type strong magnetic ore separation machine forever.This utility model needs handling part when dry type wet magnetic separation is changed, and reduces efficiency of magnetic separation and can not circulate magnetic separation.
Traditional magnetic separation mode generally adopts continuous multi-stage concentration equipment to carry out magnetic separation, and floor space is big, long flow path, is not easy to management, and the utilization rate of raw material is subject to the restriction of magnetic separation hop count.As the Chinese patent CN101954311B a kind of iron ore dry powder magnetic separation technology announced and equipment just have disadvantage mentioned above.
Summary of the invention
For overcoming the defect of existing dry-and wet-type magnetic separator, it is an object of the invention to provide one and can circulate magnetic separation, improve in fluvial sand, ore pulp, the mixed liquor of nonmetal fine particle and iron tramp or the utilization rate of mixture, the circulation conduit of mineral is simply not easily blocked, and can meet the dry-and wet-type circulation electromagnetic separator of the sealing treatment feed of dry type and wet magnetic separation requirement, solves traditional magnetic separation mode floor space big simultaneously, long flow path, is not easy to the shortcomings such as management.
The technical scheme is that and be achieved in that:
