Definitions

  • the invention relates to a circuit grinding device with a high-pressure roller press for crushing granular good material and with Integrated classifier, both units surrounded by a housing which consists of two fixed side end walls, between which a rotatably mounted, rotatable material conveyor ring is arranged for an internal good material cycle, the good material inlet through one or more openings in one or both side walls of the housing and the Good material outlet also laterally through one or more openings in the front wall of the housing.
  • the ring takes the press discharge material (Schülpen material) depending on the design from lifting elements in the conveyor ring to the area of the upper one Apex of the ring and leaves this good material from above fall into the nip, causing the internal good material cycle comes about.
  • Bucket elevators or other space-consuming conveying bodies for transporting the press discharge material to the press inlet omitted.
  • the compact circuit grinding device of DE-A-196 30 687.6 above the rotatable bar basket lying horizontally on the roller press a dynamic bar sifter arranged, the of Bar basket through which visible air flows from the area of the upper apex the material to be discharged from the material discharge ring recorded and from this separates the coarse grain fraction, the one below Rollers fed for the purpose of further grinding is, while the visual air loaded with the fine material fraction from the The rod basket is withdrawn and outside the circuit grinding device from the visual air is separated.
  • the invention has for its object the preamble of Circuit milling device forming claim 1, especially with regard to the overall low specific Energy requirements and problem-free grinding even of moist goods.
  • Characteristic of the circuit grinding device according to the invention with roller press and integrated classifier is that the classifier below of the nip of the two rollers in the housing with the rotatably mounted material conveyor ring is arranged. This will first achieved that the sifter of the press discharge material, before it gets onto the rotating material conveyor ring and from this is transported upwards, separates the fine material and this removed from the housing of the circuit grinding device, so that the rotating material conveyor ring already the separated fine part no longer has to be transported.
  • a static classifier namely according to another characteristic of Invention a static cascade classifier with at least one row cascade-like or venetian blind-like one above the other arranged baffles, their spaces in cross flow are flowed through by sight air.
  • a static cascade sifter also acts as a disagglomerator for those of the Pressed agglomerates (slugs). The deagglomeration the Schülpen is practically free of charge from the cascade sifter whithin.
  • the slugs of the press discharge material may be together with the fresh material fed to the circuit grinding device, such as e.g. Cement clinker blocks placed on top of the cascade sifter, and the mixture of materials moves from above by gravity down over the cascade or blind-like arrangement Baffles and it is circulated, the Schülpenmaterial deagglomerated, which at the same time approximately in cross flow from the Visible air is flowed through, which is able to do both fine material contained in the Schülpenmaterial as well as possibly in the fresh goods from the material moving from top to bottom through the classifier to see out, and only the classifier coarse fraction freed from the fine material, gets onto the rotating material conveyor ring and is taken up by it and reaches the upper one Peak again in the nip of the roller press.
  • the circuit grinding device such as e.g. Cement clinker blocks placed on top of the cascade sifter
  • the Deagglomeration of the scaly material can be done by grinding media also fresh cascades falling cascading downwards such as. Cement clinker blocks are effectively supported. Your own separately powered disagglomerator such as Impact hammer mill to deagglomerate the press sleeves before entry in the classifier is unnecessary.
  • the compact circuit grinding device according to the invention with integrated High pressure roller press and classifier also opens up the possibility the grinding device in contrast to previous high pressure high pressure roller presses with a not too high one Operate pressure to reduce less hard material material to produce with less sharp-edged particles, which the Wear on the roller press itself as well as on the classifier is reduced.
  • the pressure is not too high the grinding stock reaches a broader grain distribution curve in the grinding product, what with many products such as is desirable for cement. ever less hard coming from the high pressure roller press Schülpen are, the easier they are then immediately downstream classifiers such as Cascade sifter or rod basket sifter deagglomerate.
  • the one with a less high pressure the increasing recycle grinding system circulation rate to be expected of the Schülpen can then by the classifier, especially if the classifier is static Cascade sifter is easily coped with.
  • the inside of the rotating material conveyor ring below the Roller press arranged sifters can also be a dynamic one Be a sifter, its rotating dust basket below the press rolls is arranged parallel to these, at least in the area one end of the rod basket in the adjacent housing end wall a discharge elbow for the extraction of the fine goods Visible air is arranged.
  • the two are driven in opposite directions and rollers 10 separated from each other by a nip, 11 surrounded or enclosed by a housing, consisting of two fixed, i.e. non-rotating side end walls 12, 13, between which a material conveyor ring rotatably mounted on rollers 14 and 15 16 is arranged for an internal material cycle.
  • the Rotation of the material conveyor ring 16 takes place via its cylindrical Coat e.g. by the driven bearing roller 15.
  • the bearing blocks of the two rollers 10, 11 in one Machine frame 17, 18 mounted, which is part of the fixed Side end walls 12, 13 can be.
  • a static one Cascade classifier arranged with at least one row cascade-like or venetian blind-like one above the other arranged baffles 19, the spaces in the Cross flow of visual air 20 are flowed through from the side through at least one feed housing 21 through at least one of the Side end walls 12, 13 through into the space below the roller press is introduced.
  • This cascade sifter, flowed through by visible air acts as a deagglomerator for the roller press sleeves 22, which together with the fresh regrind 23 the cascade sifter be abandoned.
  • one of the housing end walls 12, 13 can be introduced fresh material 23 but also via line 23a directly from above the nip of the Roller press 10, 11 fed through a higher side opening become.
  • the classifying air 20 sifting through the classifying material Fine material fraction, and the visual air loaded with fine material 24 becomes withdrawn via line 25 from the circuit grinding device, while the coarse grain fraction separated from the classifier by the classifier 26 on the inner track of the rotating one, which may be provided with lifting elements
  • Material conveyor ring 16 arrives, the coarse grain fraction 26th takes up to before the top vertex of the ring 16 and this good material 27 in the nip of the roller press 10, 11 drops. That means that the material bed shredding in the high pressure roller press 10, 11 is relieved of the fines 24.
  • the wet material could glue the inner wall of the material conveyor ring 16 a hot gas stream is used as viewing air 20, which contains the moist good material effective in its disagglomeration in the cascade sifter can dry, so that the energy-saving circular grinding plant, the due to an extremely low specific energy requirement (kWh / t) is also used for grinding moist goods can be.
  • FIG. 2 shows that below the roller press 10, 11 within the rotating material conveyor ring 16 instead of the static cascade sifter 19 or even a dynamic one in addition to this Classifiers with rotatably mounted rod basket 28 can be arranged, e.g. via a speed-adjustable electric motor via a shaft 29 is driven.
  • the housing walls 12, 13 of the grinding device are the classifier housing at the same time.
  • In the area of the ends of the rod basket 28 are in the adjacent housing end walls 12, 13 discharge elbows 30, 30a for the extraction of the fines 24 loaded Visible air arranged.
  • roller presses also roller crushers or roller mills can be used, usually with a lower roller pressure work as roller presses.
