Definitions

  • the invention relates to a classifier mill according to the preamble of claim 1.
  • Eddy current mills are known, for example, from their own patent EP 0 787 528 B1 and have a grinding gap defined between a stator and a rotor.
  • Eddy current mills operate on the principle of the impact mill with a rotor arranged vertically and a stator surrounding the rotor on the radial side.
  • the stator usually has a frustoconical grinding track with an inwardly directed, in the axial direction, ie vertically extending corrugations, which is usually mounted in a housing of the eddy current mill.
  • the rotor which can be driven at high speed, is provided, which is equipped along the axial direction with one or more several so-called grinding rings, which are carrier elements for the grinding tools.
  • the grinding rings are in turn equipped along the circumferential direction with a plurality of grinding tools.
  • jet mills in which particles are ground in a gas stream, without this mechanical tools such.
  • B. high-speed rotors are used. The comminution of the particles takes place via the energy introduced by the grinding gas.
  • a cyclone separator is provided after the mill in order to separate the grinding gas from the grinding dust.
  • the bulk material to be milled is at a Mahlgutaufgabe abandoned and passes from there into a grinding area around which compressed air nozzles are arranged, the compressed air jets detect the discontinued bulk particles and accelerate in a concentric direction, so that they collide against each other and thereby be ground.
  • Air separators serve to separate a coarse material fraction from a fine material fraction from a heterogeneous mixture of different particle size.
  • the discontinued bulk material is already a relatively finely ground mixture, ie a u. U. in a further process step pre-milled mixture.
  • Air classifiers have one or more classifier wheels arranged above a classifier space, wherein the particles of the item to be viewed are taken along by an upwardly directed air stream in the classifier space or, if the particle is too heavy, are not taken along. Of the light particles that reach the classifier wheel, only those particles that are smaller than the corneal limit defined by the classifier wheel can pass the classifier wheel. The others fall behind.
  • a jet mill For the separation of various constituents in a millbase from each other, it is also known, upstream of the air classifier, which has a relatively blurred separation boundary, a jet mill. Also, such jet mill classifier combinations are commonly referred to as jet mill or fluid bed counter-jet mill. Such a fluidized bed counter-jet mill is known from the German patent application DE 101 164 83 A1 known. The use of such a fluidized bed counter jet mill for separating various constituents of the millbase is known from the German patent application DE 10 2006 001 937 A1 known. In this case, adjoining the grinding area of the fluidized bed counter-jet mill is a riser area serving as a classifier space, wherein an air classifier wheel is arranged above the riser area.
  • Finely ground particles with a large mass-related surface are removed via a fine material discharge which adjoins the air classifier in the upper region of the jet mill, whereas particles of lower fineness begin to sink back into the grinding zone at a height of the riser region corresponding to their weight or their mass-related surface.
  • abrasive components such as quartz can be discharged from a bentonite regrind without being subjected again and again to the grinding process ,
  • classifier mills from the company Alpine, type ZPS or type Mikropul ACM, the company Altenberger rotor, which is assumed here as a generic state of the art. These classifier mills are also based on a combination of an air classifier and a wind sifter upstream, arranged below the classifier mill. Instead of a jet mill, however, a kind of hammer mill with a rotating disk is used here, on which fingers acting as hammers protrude upwards. The millbase is placed on a Mahlgutiergabe above the rotor disk of the hammer mill and then falls by gravity induced on the provided with the fingers rotor disk of the mill, where a crushing, ie grinding takes place.
  • the riser or classifier space of the classifier closes, wherein a fan together with the air classifier in the classifier space generates an upwardly directed air flow which leads the ground material ground on the hammer plate upwards and out through the classifier arranged above it.
  • Particles that are light enough that is, ground well enough reach the top of the airflow.
  • Heavy particles are first ground and then rise or fall back onto the mill before they reach the sifter.
  • the classifier wheel itself is then still a separation of the sorterrad reaching, relatively light particles, with only particles pass through the classifier wheel, which are smaller than the predetermined by the safety wheel grain upper limit.
  • Such a classifier mill is also shown with a finger disk hammer mill upstream of the air classifier.
  • the feed material fed to a feeding hopper is fed via a screw from below to the finger disk mill and then blown upwards by compressed air through the mill.
  • the mill is adjoined on the upper side by a riser area, which is formed by a tube opening into the classifier space below the classifier and the classifier space, whereby particles which are too large or too heavy to pass through the classifier sink again into one enter the tube radially surrounding area. There, a stream of air is blown through another nozzle, which flows up through a sieve and raises the sinking particles again.
  • an outlet opening in the mill housing is provided on a wall area above the screen, which opens into a return channel leading to the feed screw via which the mill is fed. A part of the coarse material is thus discharged from the preparerraum then fed again from below to the mill. It can be determined via a flap, how much coarse material is discharged.
  • the classifier mill thus fulfills the function of gravity precaution in the riser area and the return of the coarse material to the mill entrance.
  • the company Altenberger rotor offers a relatively weak grinding action, so that many particles of the ground material to be crushed and classified rise in several iterations and sink again and again must be ground before they fit through the classifier wheel. It can thus be processed only a relatively small amount of ground material per unit time. The per unit time at the Mahlgut- or Grobgutaufgabe available amount of ground material is thus limited.
  • the grindable amount of regrind is at the in the EP 0 118 782 A2
  • the classifier grinder shown additionally limited by the coarse material limiting the dischargeable Grobgutmenge, which makes either a required at relatively small intervals cleaning the mill from above the sieve coarse material required or such a long service life or such a long run after the abandonment of the grind until the Coarse material which has arrived there is returned to the mill through the return channel and ground.
  • the classifier space thus forms a fall area through which the coarse material rejected at the classifier wheel falls back into the mill. Since the entry of the spiral channels into the classifier room is at the upper end of the classroom, there is no gravity precalibration in the classifier room itself. Rather, the gravity caused by the sinking of coarse particles in the rising spiral channels by blowing an increased air flow and frequent cleaning must be countered, the throughput should not decrease or even clogging of the spiral channels occur. Overall, the economics of the classifier mill is therefore low.
  • Classifier mills of the generic type are based on the known combination of an eddy current mill with an air classifier. Furthermore, in the generic case, the flow directed downwards in the eddy current mill and directed mostly in the horizontal direction or downwards from the eddy current mill is deflected by a flow deflection device into a riser region, namely into an ascending flow direction required there.
  • the grinding area is formed by a grinding gap between a rotor and a stator of the eddy current mill, wherein the rotor is preferably arranged with a vertical or nearly vertical axis of rotation.
  • the millbase fed to the grinding material feed above the eddy current mill is thus initially conveyed by gravity and the suction produced by the rotor of the mill downwards through the mill to the flow or grinding material outlet below the grinding region defined by the grinding gap.
  • the flow diverter fluidly connects the flow outlet of the eddy current mill to a flow entry of the riser area.
  • the flow inlet opens at a vertical distance to the classifier wheel in the riser.
  • the flow inlet of the riser region must be spaced vertically from the classifier wheel so far that the riser region can fulfill its function as a classifier space.
  • the flow deflection device has the function of fluidically connecting the riser inlet or inflow inlet with the mill outlet and redirecting the flow emerging from the flow outlet of the eddy current mill such that an upward flow direction prevails in the riser region, preferably vertically upwards.
  • the riser of the air separator is not only below the crusherrads and has at a vertical distance to prepare for the mill outlet flow inlet, but is also above the eddy current mill, wherein the underside of the riser a fall area connects, which opens into the provided on the upper side of the eddy current mill inlet through which from the Rising region sinking Mahlgutteilchen in the grinding area of the eddy current mill are traceable.
  • the riser or classifier space fulfills its function as a classifier space, namely that the particles entrained by the ascending air flow in the riser area, depending on the particle size, are led to the classifier wheel or sink again.
  • the classifier space the function of which is that only particles that are light enough in the upwardly directed air flow are taken up to the classifier wheel above the classifier space, can serve as a riser area, if the flow entry of the riser area as far vertically spaced from the classifier wheel is that the riser or bombarderraum fulfills its function as conveyerraum.
  • the fall area adjoining the riser area above the mill inlet hereby achieves a spacing of the mill inlet from the conveyeraumeinlass, so that the suction acting on the inlet of the mill does not falsify the sighting and does not suck the particles injected into the classifier space back into the mill on the inlet side ,
  • the riser of the air classifier can thus be located directly above the eddy current mill. Because of the intended case area of the reformeraum but also something to the vertical offset above the mill can be arranged.
  • the flow inlet of the riser region may for this purpose preferably open from below vertically or at least with an upward angle in the riser region and thus form part of the flow deflection.
  • the flow entry of the riser region could also be guided from the side horizontally or at an upward angle into the safety area, for example when structural conditions require it.
  • appropriate measures for deflecting the flow from the direction of entry into the vertical direction must be made in the classifier space or in the riser area as part of the flow deflection device, for example baffles or pipe sections, or an additional blower moving the flow upwards.
  • the riser can be designed as a vertically aligned shaft with a circular or square cross-section.
  • the fall region may, for example, have the shape of a channel tapering downwards from the flow cross section of the riser region down to the mill inlet.
  • the Strömungsumsch could theoretically be fully integrated into the housing of the eddy current mill, especially if the riser of the air classifier is located directly above the eddy current mill, which in many cases, even for structural reasons, but also to achieve below explained in more detail advantages is preferred.
  • the flow deflection device will comprise a mills external and external space connection between mill outlet and classifier inlet, wherein at least a certain part of the flow deflection can be effected in this connection.
  • the flow deflection device can comprise both such an external portion as well as further measures in the classifier space and / or in the mill housing.
  • the flow diverter is preferably formed as at least one running with radii of curvature Mahlguttechnischsrohr between the mill outlet and the reformerraumeinlass or includes at least one.
  • the grinding stock pipe may be guided in a 180 ° bend or with two 90 ° turn sections to just below the classifier room entrance and there via a further 90 ° curve section from the horizontal in the view of the sifter in the vertical direction.
  • the Mahlgut Extremsrohr between the mill outlet and the reformerraumeinlass or the mill outside and reformerraumexterne connection between mill outlet and reformerraumeinlass thereby removable and can thus be easily cleaned. Because in many other applications, only a grind or just a sighting of the feedstock is desired. Taking away the connection between the mill outlet and the classifier inlet, the classifier mill according to the invention can also be used for mere grinding or for mere sifting by picking up the material to be ground at the exposed mill outlet or giving up the item to be viewed at the exposed classifier or inlet area inlet.
  • At least the eddy current mill preferably also the at least one classifier wheel are independently drivable.
  • the eddy current mill can have a width-adjustable conical grinding gap, that is to say a frustoconical grinding track and a height-adjustable rotor which, with its grinding tools, strips off a frustum-shaped web which forms the inside of the grinding gap.
  • the rotor carries on grinding rings the grinding gap radially inside defining grinding tools.
  • a selective grinding is desired, ie a discharge of the particles sinking from the classifier space separately from the fine material discharged at the classifier wheel.
  • a Grobgutaustragsvorraum is advantageously provided below the riser, via which from the riser sinking Mahlgutteilchen
  • the classifier mill are dischargeable.
  • discharge devices operating at intervals such as, for example, rotary valves, such as, for example, a coarse material discharge screw guided horizontally or advantageously in the horizontal direction through the ascending or, preferably, falling area, in a horizontal or predominantly directional component.
  • the fall region can then be designed as a funnel element tapering from above to the coarse material discharge screw.
  • the coarse material discharge device is preferably arranged above the eddy current mill, i. the inlet of the eddy current mill and the lower side exit for the heavy particles at the riser area fluidly interposed in the fall area. If the coarse material discharge device is mounted there removably, the classifier mill can be operated either in the operating mode "complete grinding” or “selective grinding” by removing or attaching the coarse material discharge device at the intended location.
  • a fall-well steering device which selectively supplies the particles sinking from the rise region to the coarse-product discharge device or returns them to the mill. It would also be conceivable to design the drop-type steering device in such a way that a certain, adjustable proportion of the sinking particles is guided into the coarse material discharge device and the remainder is returned to the mill.
  • a funnel element tapering from above to a longitudinally extending funnel outlet opening is provided as a fallgutlenkvortechnisch, which has a funnel wall on both sides along the funnel outlet opening, wherein at least one the two hopper walls is movable, so that the funnel outlet opening either in the Grobgutaustragsschnecke or next to the fall area, ie ultimately can be performed to the mill inlet.
  • this temperature increase in the mill can be avoided completely or at least insofar as the temperature rise is not critical for the milling process.
  • a line can be provided, through which the discharged coarse material is supplied to the feed material, in front of a cooling device, which with the feed material cools down the added coarse material to the application temperature.
  • cryogenically coolable classifier mill also also has the above-described fall-well steering device, several modes of operation are possible: on the one hand, selective grinding with two separately discharged fractions, the fine material discharged at the classifier wheel and the coarse material discharged at the coarse material discharge.
  • a cryogenic cold grinding in which the coarse material discharged on the coarse material discharge or the coarse material discharged coarse material in cold and thus brittle state again fed to the mill and ground.
  • a grinding in which by appropriate position of the Fallgutlenkvorides the coarse material discharge, so for example, the coarse material discharge screw is covered, so that the sinking Grobgutteilchen directly fall back into the grinding area of the eddy current mill.
  • a control device for controlling the position of the Fallgutlenkvoriques is also provided, or in a further development of a control device for controlling the position of the Fallgutlenkvorides in response to e.g. the tapped in or on the eddy current mill temperature.
