Definitions

  • the invention relates to a mill with several grinding stages for the treatment, especially for crushing, drying, grinding, coating and Deagglomeration / dispersion of dry or moist material according to claim 1, with inlet and outlet devices for carrier gas and Good, consisting of a cylindrical or frustoconical, drivable rotor with several superposed circular disks and circumferentially distributed, blow bars, with a likewise cylindrical or frustoconical, all Mahlebenen common stator.
  • the invention particularly relates to a mill with light weight replaceable blow bars with appropriately designed mill housing.
  • a mill which has a disk-shaped, identifies radial carrier for the grinding media equipped rotor.
  • the carriers are provided on its top and bottom with brackets or recesses, the Keep the grinding media against the centrifugal force.
  • On the rotor are between two adjacent radial supports mounted around the rotor rotatable clamping rings, the lock the grinding media.
  • this mill were the screw connections replaced.
  • this construction is very expensive to manufacture and the Mounting is not much easier.
  • the mills described in the prior art have all milling stages, which in each case several grinding tools are assigned and there individually or be fastened together.
  • DE 100 53 946 the milling stages through Limited annular baffles that are inserted between the grinding tools.
  • the replacement or assembly of the grinding tools is pressure shock resistant Execution, without large doors, not possible without dismantling the machine.
  • the blow bars can by their easy interchangeability to the appropriate Mahlaufgabe be adapted.
  • the grinding gap between the grinding track on the stator and the blow bars can by simply replacing blow bars by others, with different depth and profile, slightly changed in width and geometry become.
  • the grinding gap can thus be adapted to every task and every product become. Compliance with the accuracy of Mahlspaltweite is given.
  • the one-piece blow bars have two functions, a Mahlditerfunktion and a hold function.
  • the area of the blow bars with hold function is like this formed that the blow bars in the recesses with undercut of the Circular disks can be inserted on the rotor from top to bottom.
  • the Area with Mahltrainrfunktion is in the installed state radially, parallel to the rotor axis aligned. This range can be about the height with any profile and in Any depth can be made, so that by replacing the blow bars the Mahlspaltweite and geometry can be easily changed.
  • the blow bars may be formed so that they are in the gap between Protruding the circular disk and the grinding track, cut exactly with the circular disks or the circular disks protrude farther into the grinding gap than the impact disks.
  • the illustrated in Figure 1 variant of the mill 1 according to the invention consists of a rotor 2 which is enclosed by a stator 3 with a grinding track. Of the Rotor 2 is driven by a drive unit, not shown. The mill is fed in this embodiment from below with regrind and carrier air. At the Upper end of the housing is the outlet for product and carrier gas. Also at the upper end of the housing is a closable opening 7 through which the blow bars 6 pulled out of the mill 1 or used will have to disassemble without the mill 1.
  • the rotor 2 consists of several superimposed circular disks 4 in which the blow bars 6 held become.
  • FIG. 2 shows the rotor 2, with the circular disks 4 arranged one above the other shown.
  • the circular discs 4 have recesses 8, here in the form of angled slots that the blow bars 6 by plugging in from above take up.
  • a holding plate is arranged below the lowest circular disc, which prevents slipping of the blow bars 6.
  • the blow bars 6 according to Figure 3 are designed as folded sheets.
  • the Blow bars can be divided into two sections with different functions Divide, the right side in Figure 3 represents the area with Mahlellerfunktion and the left side of the area with hold function.
  • the contour of the thigh with Holding function fits in the recesses 8 of the circular discs 4. If the rotor 2 in Staggered rotation, the blow bars 6 are located on the radially outer side of the Recess 8 and are held so.
  • a recess 9 is provided in the one Hook which has been inserted through the opening 7 in the mill, engages around the To pull or introduce blow bars 6 out of the machine.
  • blow bars 6 can different contours in Mahltrainr Scheme exhibit.
  • the blow bar is executed with a straight contour, while the Blow bars 6 are executed in Figure 1 and 2 bulging.
  • FIG 4 is another embodiment of the blow bars 6 and the Circular disks 4 shown for the mill 1 according to the invention.
  • the circular disks 4 have slot-shaped recesses 8 at the edge, which extend in a diamond-shaped, followed by a second diamond-shaped extension.
  • the corresponding blow bars 6 are rectangular and have holes in the intervals that the Intervals of the circular disks 4 on the rotor 2 correspond.
  • Screws or bolts 10 are used. Be the blow bars 6 from above inserted into the rotor 2, the screws or bolts 10 are exactly in the recesses 8 of the circular disks 4 and hold the bat 6 so in the rotor. 2 With an equipment of the blow bars 6 with screws 10, the depth of the the blow bars 6 in the grinding gap rich set by means of screws 10 become.
  • the recesses in the circular disks may be designed as slots which are radially away from the edge or at an angle to the radial direction, in order then to have a distinction.
  • This undercut can be designed on one side or on both sides and be formed in any geometric shape, for. B. rectangular, circular or triangular.
  • the blow bars can have a wide variety of contours, for example straight, bulbous but also increase in width across the height of the racket or decrease. But there are also all combinations of these contours feasible and projections and recesses.
