Definitions

  • the invention relates to a circuit grinding device with a high-pressure roller mill for crushing granular good material and with at least one integrated classifier, with both units inside two fixed side end walls and one in between lying rotatably mounted rotating material conveyor ring are arranged for an internal good material cycle, whereby the good material inlet through one or more openings in one or in both housing end walls from the side and the good material outlet also laterally through one or more openings in the front wall of the housing.
  • the ring takes the material to be removed from the mill or press (Schülpenmaterial) depending on the design of lifting elements in the conveyor ring up to the area around the upper apex of the ring and leaves this good material from above into the nip fall, which creates the internal material cycle is coming.
  • Bucket elevators or other space-consuming conveying bodies to transport the mill or press discharge material to Mill or press infeed is eliminated.
  • With the rotating material feed ring is so in the smallest space and with little mechanical Effort with a multiple internal material cycle repeated material bed stressing of the good material reached, whereby also relatively high good circulation loads, caused z. B. through reduced roller pressures.
  • the well-known is in the housing Cycle grinding devices a through which visual air flows static and / or dynamic classifier integrated, and the with the Fine air fraction from the regrind laden visual air is drawn off and outside of the circuit grinding device from the fines fraction Cut.
  • the invention has for its object a circular grinding device of the type mentioned so far that seals between the fixed side end walls and the one in between not rotating material conveyor ring are more necessary.
  • Characteristic of the circuit grinding device according to the invention is that the two fixed side end walls over the rotatable material ring housing part, z. B. ring housing part to the entire working area of the circular grinding device tightly enclosing housing summarized are.
  • the housing part at least one grist leakage discharge on its underside such as B. funnel for discharging or collecting such regrind leakages on, which recirculates with advantage in the grinding cycle become.
  • any seals between the fixed side end walls and the rotatable one in between Material conveyor ring not required.
  • a classifier can be above or below the roller mill be arranged.
  • two static ones that are approximately mirror images of each other Cascade sifters can be arranged, and on the underside of the housing part Two grist leakage discharges can also be used to absorb regrind leakage such as B. funnel for receiving such Leaks should be arranged.
  • the fixed, the rotatable Material conveyor encapsulating housing part in particular Ring housing part which at the same time optimal protection according to the Occupational safety guidelines offers, divided, in particular divided in half his.
  • the material to be ground is passed through openings 18 and 19, respectively in one or in both housing end walls 12, 13 in the work area the circuit grinding device introduced, namely through opening 18 directly into the feed chute 20 of the roller mill and / or through opening 19 into the space below the roller mill.
  • the circuit grinding device introduced, namely through opening 18 directly into the feed chute 20 of the roller mill and / or through opening 19 into the space below the roller mill.
  • the inlet opening 29 for the viewing air 23/24 or for the Drying gas is in one or both end walls of the housing 12, 13. Die from the nip of the Gutbettwalzenmühle 10, 11 downward emerging material material scraps 30 divided in quantity and possibly together with through the opening 19 introduced fresh regrind to the cascade classifiers. When the goods fall or slide over the guide walls the cascade classifier is used to view the material to be viewed in cross flow and Gut agglomerates are deagglomerated at the same time. When wet Visible goods such as B. with moist cement raw meal, this is at the same time effectively dried when a hot gas is used as the visible medium is used. Instead of the guide plate walls 27a, 27b and 28a, 28b perforated sheets such as sieve sheets etc. could also be used.
  • the two fixed side end walls 12, 13 are the one rotatable material conveyor ring 16 enclosing ring housing part 38 the entire working area of the circuit grinding device is sealed enclosing housing, i.e. the fixed Ring housing part 38 and the fixed side end walls 12, 13 are tightly connected.
  • This is the invention Cycle grinding device completely encapsulated. Seals between the two fixed side end walls 12, 13 and the one in between lying rotatably mounted rotatable material conveyor ring 16 omitted. Any grist leakage caused by these two Annular gaps can allow regrind to escape from the inside to the outside, are caught on the underside of the ring housing part 38 and they get into those arranged on the underside of the ring housing part Grist leakage discharges such as B. collection funnels 39, 40 from where from the collected leakage regrind via a not shown Conveyor body to be recirculated in a controlled manner to the incoming material can.
  • the material conveying ring 16 can be operated at a subcritical speed, e.g. B. with about 40 to 80% of its critical speed, or also with supercritical Speed, e.g. B. at about 1 to 1.3 times the critical speed operate. In the latter case, the upper area
  • the vertex of the rotating material conveyor ring 16 is a material wiping device arranged.
  • the invention would also be applicable to a ring roller mill a rotatably mounted grinding ring 16 on its cylindrical inner wall or grinding track from the inside a smaller grinding roller Diameter for single grain size reduction and / or material bed size reduction the ground material can be pressed on.
