The material that grinding roller is pulverized by the spray nozzle device of Vertical Mill thermal current the most upwards carries out sorting for the first time, and the powder after sorting is raised air-flow band in the powder concentrator on Vertical Mill top, the large granular materials slag-drip opening discharge from lower end.
Powder after sorting is become tangentially flowing from vertical ascent after entering powder concentrator with the mixture of air for the first time, in the range of between stator blade one, stator blade two, rotor blade, rotor rotate the centrifugal force formed and powder and air mixture are repeatedly sorted.Large granular materials through stator blade one is flung outward out and sinks under gravity, after leaving centrifugal force scope, falls into blanking cone one, and enters Vertical Mill through feed opening；Fine powder is after stator blade two, and the space entered between stator blade and rotor sorts again, and the coarse powder sorted is discharged by the semi-finished product discharging opening of blanking cone two, and the qualified finished product air outlet from powder concentrator top is discharged.
Rotated under the centrifugal action that formed successively through stator blade one, stator blade two, rotor by rotor, powder and air mixture are carried out respectively second time, for the third time, sort for the 4th time.Being fallen into Vertical Mill by the large granular materials after the sorting of stator blade one, another part material enters stator blade two to carry out sorting for the third time；Coarse fodder after third time sorting enters Vertical Mill by the feed opening of blanking cone one, and another part material enters rotor and carries out the 4th sorting；Semi-product material after 4th sorting is discharged by the semi-finished product discharging opening of blanking cone two, and the qualified finished product air outlet from powder concentrator top is discharged.
See accompanying drawing 1, half whole grinding vertical of the present utility model specifically includes that grinding roller 5, mill 3, lining board for grinding discs 4, blowing device 2, reductor 1, feeding mouth 12, air outlet 13, semi-finished product discharging opening 16, slag-drip opening 17, blanking cone 1, blanking cone 27, tremie pipe 8, stator blade 1, stator blade 2 10, rotor 11, and rotor 11 comprises a series of moving vane 18 being radially arranged.
When described Vertical Mill works, motor is rotated by reductor 1 band movable grinding disc 3, material falls lining board for grinding discs 4 central authorities by feeding mouth 12 through tremie pipe 8, material moves and rolling by grinding roller 5 to mill 3 edge under the influence of centrifugal force, material after pulverizing overflows from mill 3 edge, drying is taken up from spray nozzle device 2 at a high speed thermal current the most upwards, carry out sorting for the first time, powder x1 after sorting be raised air-flow band to Vertical Mill top select powder segregation apparatus in, coarse fodder c1 discharges from the slag-drip opening 17 of lower end, again grinding again is fed in mill from spout through the bucket elevator of outer circulation.
Powder after sorting is become tangentially flowing from vertical ascent after entering powder concentrator with the mixture of air for the first time.In the range of between stator blade 1, stator blade 2 10 and rotor 11, rotor 11 rotate the centrifugal force that formed by powder x1 and air mixture stator blade 1 and carry out sorting for the second time in passage that stator blade 2 10 is formed；The coarse fodder c2 that second time sorts falls in the batch mixing chamber 14 that blanking cone 1, blanking cone 27 and tremie pipe 8 are formed, then returns on lining board for grinding discs 4 through feed opening 15, grinding again.Carry out third time in the passage that powder x2 after second time sorting is formed by air-flow band to stator blade 2 10 and rotor 11 to sort；The coarse fodder c3 that third time sorts out discharges from the export of goods in process of manufacture 16 of blanking cone 7, and third time sorts out fine powder x3 and upwards goes out mill from the air outlet 13 of powder concentrator upper end with air-flow, collects, be qualified products in the dust arrester installation of system.
Referring back to accompanying drawing 2, it is shown that stator blade and the structure of rotor.Rotor 11 comprises a series of moving vane 18 being radially arranged around tremie pipe 8, and the space of internal rotor connects air outlet 13.Rotor rotates and produces centrifugal force, stator blade 1 and the adjustable angle of stator blade 2 10, such that it is able to realize the granularity regulation separated, improves Cement Quality.
Accompanying drawing 3 shows the system comprising half whole grinding vertical of the present utility model.As shown in the figure, raw material is delivered to Vertical Mill feeding mouth by elevator by feed proportioning system, after raw material grinds separation in Vertical Mill, produce coarse fodder c1, coarse fodder c2, coarse fodder c3 and powder x3, coarse fodder c1 and after belt feeder delivers to feed proportioning system mixing, deliver to Vertical Mill feeding mouth again from the discharge of Vertical Mill slag-drip opening.Coarse fodder c2, along blanking cone one entrance batch mixing chamber, enters back into Vertical Mill together with the dispensing got off with feeding mouth.The coarse fodder c3 separated further across rotor and stator blade two discharges along blanking cone two from semi-finished product discharging opening, delivers to ball milling through belt feeder.The powder x3 produced after rotor separates delivers to by Vertical Mill air outlet deliver to warehouse for finished product after dust-precipitator is collected.The discharging of ball milling delivers to powder concentrator by belt feeder and elevator, and the finished product fines that powder concentrator is selected delivers to warehouse for finished product after dust-precipitator is collected, and the coarse fodder c3 that the semi-finished product discharging opening of the coarse fodder selected grinding vertical whole with cement half is discharged is re-fed into ball milling after mixing.
By means of Vertical Mill ball milling association system of the present utility model, material is sufficiently separated, and granularity is easily subject to control, and prevents the generation of grinding.The different material of suitable granularity is made different disposal, product quality and production efficiency and is improved.
Above in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill is possessed, it is also possible to make a variety of changes on the premise of without departing from this utility model objective.
