Definitions

  • the invention relates to a Kreislaufmahl raised with high-pressure roller mill for pressure crushing granular Gutmateriales and with at least one integrated classifier, both units are disposed within two fixed side end walls and an interposed rotatably mounted rotatable material conveyor ring for an internal Gutermaterialniklauf, wherein the Gutmaterialeinlauf by one or more openings in one or both housing end walls from the side and Gutgutauslauf also done laterally through one or more openings in the housing end wall.
  • the ring takes the mill or Pressenaustragsgut (Schülpenmaterial) depending on the design of lifting elements in the conveyor ring up to the area about the upper vertex of the ring with and leaves this material from the top fall into the nip, whereby the internal Good material cycle comes about.
  • Bucket elevators or other space-consuming conveying elements for transporting the mill or press discharge material to the mill or press inlet are dispensed with.
  • the invention has for its object to further develop a Kreislaufmahl Rhein of the aforementioned type so that seals between the fixed side end walls and the interposed in rotation displaceable material conveying ring are no longer necessary.
  • the integrated into the Kreislaufmahl boots invention at least one classifier can be arranged_obergur or below the roll mill.
  • two mutually approximately mirror-image static Cascade classifier can be arranged, and at the bottom of the housing part for receiving regrind leaks can also be two Mahlgutleckage-discharges such.
  • B. collecting funnel for receiving such leaks can be arranged.
  • the fixed, encapsulating the rotatable material conveying ring housing part in particular ring housing part which also provides optimal protection according to the occupational safety guidelines, divided, in particular be divided in half.
  • the material to be ground is introduced through openings 18 and 19 in one or both housing end walls 12, 13 in the working space of Kreislaufmahl Road, through opening 18 directly into the crop hopper 20 of the roll mill and / or opening 19th into the room below the roller mill. In this room z. B.
  • each other static cascade classifier arranged, each having two between them a viewing zone 21 and 22 forming and of prepare for preparation for the drying gas approximately in cross-flow flow through reformzonebegrenzungs 1968 obliquely down to the discharge for the selected Coarse grain fraction 25 and 26 inclined cascade or louver-like arranged baffles 27a, 27b and 28a, 28b, said two baffle walls and thus the intermediate viewing zone 21, 22 are arranged obliquely with a deviating from the vertical angle.
  • the inlet opening 29 for the classifying air 23/24 or for the drying gas is located in one or both housing end walls 12, 13.
  • the Gutwerkschülpen 30 coming down from the nip of the bed of material rolls roller mill 10, 11 are divided in quantity and possibly abandoned together with introduced through the opening 19 fresh regrind the cascade classifiers.
  • the Gutwerkschülpen 30 coming down from the nip of the bed of material rolls roller mill 10, 11 are divided in quantity and possibly abandoned together with introduced through the opening 19 fresh regrind the cascade classifiers.
  • the Gutwerkschülpen 30 coming down from the nip of the bed of material rolls roller mill 10, 11 are divided in quantity and possibly abandoned together with introduced through the opening 19 fresh regrind the cascade classifiers.
  • the spreadgut In the case or when sliding the goods on the baffle walls of the cascade classifier the prepare the baffle walls of the cascade classifier the prepare for the baffle walls of the cascade classifier.
  • the baffle walls 27a, 27b and 28a, 28b and perforated plates
  • the coarse grain fraction 25, 26 separated from the static goods by the static cascade classifiers reaches the inner web of the rotating material conveying ring 16, optionally provided with lifting elements, which carries this coarse grain fraction up to the upper vertex of the ring 16 and this good material 31 into the feed chute 20 of FIG Roll press 10, 11 drops, so that this material is subjected to a repeated or repeated Gutbettzerkleintation which is relieved of fines insofar as the fines fraction leaves the static cascade classifier together with the classifying air and in downstream dynamic classifiers each with a rotatably mounted rod basket 32, 33, the bearings are advantageously arranged outside the two fixed housing end walls 12, 13, a further sighting is supplied.
  • the two fixed side end walls 12, 13 are summarized via a rotatable material conveying ring 16 umhausendes ring housing part 38 to the entire working space of the Kreislaufmahl observed tightly enclosing housing, i. the fixed ring housing part 38 and the fixed side end walls 12, 13 are sealed together.
  • the Kreislaufmahl driven invention is completely encapsulated. Seals between the two fixed side end walls 12, 13 and the intermediate rotatably mounted rotatable material conveying ring 16 omitted. Any regrind leaks, which can leave through these two annular gaps grinding material from the inside out, are collected at the bottom of the ring housing part 38 and they get into arranged on the underside of the ring housing part Mahlgutleckage-discharges such. B. collecting funnel 39, 40, from where the collected leakage ground material can be controlled via an unillustrated conveying member controlled to Gutermaterialeinlauf.
  • the material conveying ring 16 can with subcritical speed, z. B. with about 40 to 80% of its critical speed, or with supercritical speed, z. B. be operated with approximately 1 to 1.3 times the critical speed. In the latter case, a Materialabstreif shark is arranged in the region of the upper vertex of the rotating material conveying ring 16.
  • the invention would also be applicable to a ring roller mill with a rotatably mounted grinding ring 16, on the cylindrical inner wall or grinding path from the inside a grinding roller of smaller diameter for the purpose of single grain size reduction and / or comminuted comminution of the ground material can be pressed.
