The course of work of the present invention is: block stock O to be comminuted is entered in milling equipment M1 by powder concentrator feed pipe device 1 and carries out initial grinding, by the air-flow possessing certain speed, the at different levels material A BCs different through preliminary grinding particle size are entered in powder concentrator from the grinding zone of milling equipment M1 afterwards, directly enter multi-stage separation particle size adjustment system 4.The outer ring annular plate blade 401 of described multi-stage separation particle size adjustment system 4 carries out primary separation to the multistage particle diameter material entered in powder concentrator, the material be separated and final finished material A and the mixture of semi-product material B enter inner ring annular plate blade 402 and are again separated, and are separated remaining material and semi-product material C enters milling equipment M1 again by grinding by its semi-product material conveying device 2 503 by outer ring annular plate blade 401.Enter the inner ring annular final finished material A of plate blade 402 and the mixture of semi-product material B under itself and dynamic rotor 3 synergy, isolate final finished material A and semi-product material B, its final finished material A and air-flow be mixed by final finished device for transporting objects 501 export to powder concentrator outer after enter gathering dust in technological process in grinding system, and semi-product material B is also outputted to outside powder concentrator by semi-product material conveying device 502 and enters in the technological process of milling equipment.
By reference to the accompanying drawings shown in 2, the present invention is described in further detail and how accomplishes graininess granular material mixture multi-stage separation.Outer ring annular plate blade 401 is made up of incision blade 401a and swirl vane 401b, its combinations of pairs is a pair vane group, space bar device 401c is had between incision blade 401a and swirl vane 401b, its function is isolation incision blade 401a and swirl vane 402b, stops air-flow and material and enter powder concentrator powder-separating area in the middle of these two blades.Air-flow and mixtures of materials at different levels by outer ring annular plate blade 401 often pair of vane group between gap enter powder concentrator first powder-separating area XX, in this powder-separating area, material bears the effect of airflow buoyancy and self gravitation.Under the drive of air-flow, first the maximum coarse granule material of particle diameter contacts with incision blade 401a and falls down after clashing into its surperficial stall, simultaneously, swirl vane 401b causes the air-flow entered between often pair of vane group gap produce the eddy current physical effect of WW in regional area and cause coarse granule to fall down under self gravitation effect in the instantaneous stall in this region, other small particle diameter material is taken away the first powder-separating area XX because quality is little under airflow buoyancy effect, namely produces the effect of separation.The impact on its surface of material impacting and time started is controlled thus the particle diameter (μm) of the material that controls to drop or fineness (cm2/g) and total amount (t/h) by regulating the angle [alpha] of incision blade 401a.Controlled vortex flow strength size and eddy region area is come thus in controlled vortex flow region, WW drops the particle size (μm) of material or fineness (cm2/g) and total amount (t/h) by regulating the angle beta of swirl vane.
Enter the multistage mixture material of powder concentrator at the mixture AB being isolated semi-product material C, final finished material A and semi-product material B by the first powder-separating area XX, its the latter enters the second powder-separating area YY be made up of inner ring ring-type plate blade 402 and dynamic rotor 3, in this powder-separating area, material bears the effect of airflow buoyancy, self gravitation and centrifugal force.Dynamic rotor 3 rotates and produces centrifugal action to the material at the second powder-separating area YY, the quality material that greatly namely particle diameter is large causes stall to drop because centrifugal force clashes into greatly and first the guide vane 402a of inner ring ring-type plate blade 402, and other small particle diameter material is taken away the second powder-separating area YY because quality is little under airflow buoyancy effect.Material from inner ring ring-type plate blade 402 drops is semi-product material B, under airflow buoyancy effect, be final finished material A by the material taken away.The impact on its surface of material impacting and time started is controlled thus the particle diameter (μm) of the material that controls to drop or fineness (cm2/g) and total amount (t/h) by the angle γ of adjustment inner ring ring-type plate blade 402a.Controlled the centrifugal force of different-grain diameter material by adjustment dynamic rotor 3 speed of gyration, its strength of clashing into guide vane be there are differences, thus control the particle diameter (μm) of material or fineness (cm2/g) and total amount (t/h).
In embodiment of the present invention, separately have any different in above-mentioned regulative mode, the buoyancy of material is adjusted by the air quantity (m3/h) of air-flow in powder concentrator, under the prerequisite that powder concentrator mechanical dimension specification is certain, by the air quantity of the first powder-separating area XX and the second powder-separating area YY, the larger buoyancy produced material of its value is just large, vice versa, the logistics of different-grain diameter is taken away powder-separating area under the effect of airflow buoyancy, and the particle diameter (μm) of such product or fineness (cm2/g) and output (t/h) just can make flexible modulation
Structure, ratio, size etc. that the present embodiment institute accompanying drawings illustrates, content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the present invention, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the present invention can produce and the object that can reach, still all should drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, quote in this description as " on ", D score, "left", "right", " centre ", " clockwise ", " counterclockwise " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the present invention.
