Definitions

  • the invention relates to a Kreislaufmahlstrom for grinding of Fresh goods, with a high-pressure roller mill or roller press with Gutbettzerkleintation of the feed, and with a classifier, comprising a static cascade classifier, the visible air flow side at least one further classifier is connected downstream, its Grobgutaustrag with the Gutaufgabe the roller press in conjunction stands.
  • the grinding cycle is the fresh goods introduced, in particular by abandonment to the Roller press or else by abandonment to the cautious, and from the grinding cycle, the finished fine finished product is discharged, namely by means of the indoctrier leaving the sight gas stream.
  • the cascade viewer acts as a custody chamber for the im Circulatory guided regrind and at the same time as disagglomerator for Dissolution of the still existing in the circulation sludge, so that as a Nachsichter downstream dynamic rod sifter with its rotating turbo elements no longer with coarse grain components is charged.
  • Both the static cascade viewers as well as those separated from the regrind by the Nachsichter Coarse grain fraction may return to the roller press for further Good bed stress and further grinding be recirculated.
  • the invention is based on the object, a compact Kreislaufmahlstrom with Gutbettzerklein mecanics roller mill or roller press and to provide sifter means in which the problem of mechanical transport of circulated ground material minimized is.
  • the product discharge of the static cascade classifier is not transferred a mechanical conveyor such.
  • B. bucket elevator but about a riser to the reform Kunststoff- and reformguteinstritt the Nachsichters, In particular, dynamic bar cage sifter transported pneumatically.
  • 100% of the material of the grinding cycle becomes pneumatic through the riser channel from the static cascade classifier transported to the top of the caretaker.
  • the drawing shows a compact Kreislaufmahlstrom with a Gutbettzerklein mecanics roller mill or roller press 10 and with a classifier.
  • the feed slot of the roller press 10 is given up to grinding fresh goods 11.
  • the millbase emerges the nip crushed and partially agglomerated, d. H. to Schellerpen 12 squeezed out, their share of already up to the desired Cement fineness of reduced particles already relatively high can be, for. B. 30% less than 90 microns.
  • the cascade viewers 13 has a V-shaped shaft-shaped housing with two of the Classifier housings enclosed and between them a viewing zone 14 forming and of classifying air 15 (or hot gas as a drying gas with moist feed material), for example, in cross-flow through visual zone boundary walls, the sloping downwards cascading or Venetian blind arranged guide plates 16a, 16b, these two baffle walls and the intermediate ones Viewing zone 14 with an angle deviating from the vertical are arranged obliquely.
  • the cascade classifier 13 is closed on its underside. Of the prepareforerabluft 18 the cascade viewers 13 is suspended in the reformerabluft 18 via a riser 19 on the roller press 10th passing pneumatically to the view air and reformgutguttritt a Vietnamesesichters in the drawing of a dynamic rod basket sifter 20 transported, whose rotatably mounted, on the rotor circumference with turbo elements provided rod basket 21 with z.
