Description

A kind of magnetic separator

Technical field

This utility model relates to Magnetic Separation Technology field, especially relates to a kind of magnetic of the magnetic separation of magnetic material, recovery Select machine.

Background technology

In conventional magnetite separation factory, for ore crushing system, closed circuit the breaking of general employing two sections or three section Ore reduction to granularity is less than 15mm or thinner by broken flow process.Ore dressing plant with good conditionsi, in ore reduction flow process, Chang Zhong Crush or after fine crushing, carry out dry type magnetic separation and throw tail, to reduce into mill ore amount, reduce the production cost in ore dressing plant.Described Dry type magnetic separation is thrown in tail operation, and many employing magnetic pulleys and the dry magnetic separator of drum-type carry out operation, owing to magnetic pulley therein is furnished with Thicker belt, reduces the magnetic field intensity in sorting district, and is limited to by self grading principle and version, and therefore, these are two years old The equipment of kind is both needed at sorting district thin uniform layer cloth, and requires that feed grade is the narrowest.And to reach these conditions, raw in reality In product more difficulty；Meanwhile, particulate and granular material are selected and point there is natural defect by they, though particulate and powder Material monomer dissociation is preferable, can not complete effectively to select point, is especially ensureing in throwing tail rate and the valuable mineral response rate, both Equipment can not be taken into account simultaneously.Further, since the sorting bed of material of magnetic pulley and the dry magnetic separator of drum-type is thin, disposal ability is little, Therefore, in mammoth mill, usually need to configure a lot of platform and carry out operation, this to the sub-material of material, gather materials, environmental protection, reduce into This grade is all a no small difficult problem.

In recent years, high-pressure roller mill has obtained wide application in magnetite separation factory, due to high-pressure roller mill Disposal ability is big, the height of the more conventional crushing circuit of fine powder content in discharge, and dissociating of mineral monomer is relatively abundant, therefore, how The discharge of high-pressure roller mill is carried out dry separation, isolates the qualified tailings the most dissociated, be elected to be industry saving follow-up mill Production cost, the problem that this is a lot of magnetic plant producer and ore dressing plant is extremely paid close attention to.In production practices, occurred height The discharge of pressure roller grinding machine carries out the work flow of dry type magnetic separation after carrying out air classification, but, due to the energy of air classification system Consumption is high, classifying equipoment and the serious wear of pipeline, investment is high, environmental protection pressure is big, to many defects such as Ore moisture content are sensitive, should Work flow is proved and is not suitable for magnetite separation factory and is eliminated.

In the recent period, occur in that again the discharge to high-pressure roller mill breaks up a few money equipment of rear directly magnetic separation, its material size energy Reaching 25mm or bigger, can select and separate qualified tailings, chats and concentrate these three product, mine tailing is directly entered stockyard heap row, essence Ore deposit enters follow-up mill and selects flow process, middling recurrence high-pressure roller mill to press again.The application of this kind equipment, although decrease and material is divided Level operation, but it practice, these a few money equipment are similar, be all in an equipment, be combined with one or more belt dry-dressing machine With the repeatedly sorting that magnetic pulley realizes material.Owing to equipment is the simple combination of multiple devices, naturally do not evade group The problem becoming the stand-alone device self of this equipment, and the load reasonable distribution of each unit in unit mahine is difficult to solve, leading portion sets Standby load can be higher, limits the ability of complete machine, and the load of back segment equipment is low, can not play one's part to the full again, thus in vain Add investment and cost in vain.Therefore, although see on the whole, the disposal ability of the said equipment is amid a sharp increase, and the efficiency of separation also has Being improved, but this kind equipment does not has substantial breakthrough, its cost performance is the highest, more has that own vol is big, weight big, cost Height, drive system are complicated, energy consumption is high, need to arrange the problems such as loaded down with trivial details cloth facility, the most seriously, the event of such unit equipment Barrier point is many, causes maintenance work difficulty big, therefore, in actual process of construction, it is necessary to higher equipment sparing rate, or needs More complicated bypass is set, thus brings the complexity of production system, working performance is low, it is difficult in maintenance to manage, production target ripple Dynamic big, investment and the problem such as cost is the highest.

Select system, conventional ore dressing plant typically to use two sections for the mill of magnetic mineral or three sections of closed circuit ball millings of wet type are carried out Ore grinding, classification, the mill rank, rank of magnetic separation select flow process: one section of ball mill mineral-feeding is Ore after broken, general granularity be less than 15mm or Thinner, ball mill ore discharging is first through spiral classifier or cyclone classification, and coarse fraction therein returns ball mill, and fine fraction feeds wet Formula drum magnetic separator sorts, to select qualified tailings and one section of concentrate；One section of concentrate enters secondary grinding classification sorting operation.For Alleviate the load of secondary grinding, typically one section of concentrate is first fed classifying equipoment, separate the more sufficient fine fraction of monomer dissociation Material, is directly entered two stages of magnetic separation, and coarse fraction feeds two-stage nitration ball mill, and ball mill ore discharging returns again to classifying equipoment, is formed closed circuit. Two-stage nitration classifying equipoment Regular History Frequency vibrosieve or cyclone, some ore dressing plants are also adopted by the combined classification stream of high-frequency screen+cyclone Journey.For guarantee enter Secondary grinding mill pulp density can reach ball mill enter to grind concentration requirement, be often additionally provided with dense before grinding machine Contracting magnetic concentration working.For there being three sections of mills to be elected to be the ore dressing plant of industry, its 3rd section of ore grinding, classification and sorting operation and second segment phase Seemingly.In order to improve the grade of final concentrate, many ore dressing plants use column magnetic separator to improve concentrate at the final stage of Beneficiation flowsheet Grade.

The mill of the conventional magneticore-dressing plant being described above selects in flow process, on the one hand, each section of ore grinding is respectively provided with graded operation, flow process And equipment configuration is the most complicated, and more toward fine grinding, the disposal ability of classifying equipoment is the lowest, cause unit Ore classification investment and Cost is the biggest.

In recent years, occurring in that three products magnetic separator, it is introduced, it can select and separate qualified tailings, chats and concentrate, chats Return ball mill, it is achieved without the mill ore magnetic selection flow process of classifying equipoment.But, owing to this kind equipment is during magnetic separation, need to add Entering substantial amounts of flushing water, therefore, chats still can not directly return ball mill, needs first to be dehydrated it, thus adds work flow Complexity；Meanwhile, the cost of this kind equipment is high, it is more difficult to maximize, and it configures with ball mill in mill selects flow process, a billiard ball mill Machine need to configure multiple stage magnetic separator, thereby results in system complex, and investment, cost are the highest.On the other hand, in routine work flow process In each stages of magnetic separation operation, wet drum magnetic separator is both needed to consume substantial amounts of under casing water, concentrate flushing water, especially with column magnetic separator Ore dressing plant, the water consumption in the Separation process of column magnetic separator is bigger, and these water eventually enter into mine tailing or concentrate, especially into mine tailing In, so that the concentration of mine tailing is extremely low, tailings dewatering, difficulty of transportation, the investment of system, cost and land seizure are the biggest.

At present, domestic ore dressing plant uses the most more of Semi-Autogenous flow process, and Semi-Autogenous flow process typically instead of old process In operation broken, in small, broken bits and part primary grinding operation, its follow-up mill selects flow process as old process.In Semi-Autogenous flow process, Raw ore after coarse crushing, granularity less than 300mm time, can directly feed semi-autogenous mill, its ore discharge through mill tail sheet every slightly, every coarse grain Degree generally 5mm～10mm, coarse fraction material returns semi-autogenous mill, and fine particle stage material typically first enters back into after cyclone classification Follow-up mill is elected to be industry.Adaptable, increasingly by the weight of people owing to flow process is short, to ore deposit of this Semi-Autogenous flow process Depending on, but, owing to whole Ores directly carry out ore grinding after coarse crushing, tail cannot be thrown in midway, does not meets and " much broken and lessmill, can throw Early throw " theory energy-conservation, cost-effective；Especially for low-grade lean ore and in, in small, broken bits during can realize throwing tail Ore, the cost using Semi-Autogenous flow process relatively can be higher；And the follow-up flow process of semi-autogenous mill is as old process, the most also Also exist and select, with above-mentioned conventional mill, the problem that flow process is identical.
