Definitions

  • the invention relates to a grinding plant and a method for grinding regrind with at least one coarse grinding circle and at least one fine grinding circle.
  • a crusherumlauf of at least 1.8 to 2.0 strive to achieve sufficiently low residue levels in the finished product.
  • the diameter of the mill can not be increased arbitrarily, since the number of spherical layers in fine-grained Combi mills becomes too large. So there is a slip between each layer, so that hardly any relative movement of the balls takes place in the inner core of the ball bed. In this area, therefore, no grinding takes place.
  • the ball mill is used for the effective deagglomeration of the goods of a good bed roller mill.
  • the invention is an object of the invention to provide a grinding plant, which is characterized by very high throughput. According to the invention this object is solved by the features of claims 1 and 9.
  • the grinding plant according to the invention consists essentially of a Grobmahl Vietnamese and at least one Feinmahl Vietnamese, the Grobmahl Vietnamese has a classifier and a Goodbettwalzenmühle and passes the pre-shredded Good the good bed roller mill in the classifier, the coarse material in turn the
  • the fine grinding circuit has a tube mill with at least two grinding chambers and a center discharge and a divider, wherein at least part of the ground material of the coarse grinding cycle is divided in the divider and fed to the two grinding chambers and the ground material is discharged from the two grinding chambers together via the center discharge.
  • a classifier is also provided in the fine grinding circuit, the classifier being supplied with the material coming from the roughing cycle and / or the material discharged from the tube mill, the
  • Coarse grinding material of the classifier passes to the divider and the fines are removed.
  • grinding balls with a diameter of ⁇ 25 mm are provided in the grinding chambers of the tube mill. Balls of this size show greater efficiency than larger balls. The use of these balls is only possible through the sighting in the rough grinding circle.
  • Gutbettwalzenmühle arrives in the classifier, whose coarse material turn the Good bed roller mill and its fine material is fed to the fine grinding circuit. Furthermore, a tube mill with at least two grinding chambers and a center discharge and a divider are used for the Feinrnahlnik, wherein at least part of the ground material of Grobmahlnikes divided in the divider and fed to the two grinding chambers and the ground material is discharged from the two grinding chambers together on the Mittenaustrag.
  • Fig. 1 is a schematic representation of the grinding plant with Grobmahlnik and
  • Fig. 2 is a schematic representation of the Feinmahlnikes according to a second embodiment
  • Fig. 3 is a schematic representation of the Feinmahlnikes according to a third exemplary embodiment.
  • the grinding installation shown in FIG. 1 essentially consists of a rough grinding circle 1 and a fine grinding circle 2.
  • the rough grinding circle 1 has a classifier 10 and a good bed roll mill 11.
  • Frischgut 3 or 3 ' is abandoned either on the classifier 10 or directly the Goodbettwalzenmühle 11.
  • the pre-shredded material 4 passes, possibly together with fresh material 3, into the classifier 10, the coarse good 5 of which in turn is fed to the fine-bed roller mill 11.
  • the fine material 6 of the classifier 10 enters the fine grinding circuit 2.
  • the fine grinding circuit 2 has a tube mill 20 with two grinding chambers 20a, 20b and a center discharge 20c and a divider 21. Furthermore, a classifier 22 and a further divider 23 are provided.
  • the product stream 6 coming from the roughing cycle is divided in the divider 21 into two equal partial streams 6a, 6b, which are fed to the two grinding chambers 20a, 20b.
  • the millbase 7 discharged from the tube mill 20 is classified in the classifier 22 into coarse material 8 and fine material 9. While the fines 9 is removed, the coarse material 8 of the classifier 22 passes into the further divider 23, which divides the coarse material into two equal partial streams 8a, 8b, which are supplied with the partial streams 6a and 6b of the splitter 21 to the grinding chambers 20a and 20b become.
  • the two grinding chambers 20a and 20b are formed identically, so that the dividers 21 and 23 are adjusted so that the grinding material 6, 8 supplied to the dividers is fed in equal parts to the two grinding chambers.
  • FIG. 3 shows a variant of the fine grinding circuit in which the divider 21 according to FIG. 1 has been dispensed with.
  • the grinding stock 6 coming from the rough grinding cycle is given to the classifier 22 and / or together with the coarse material 8 of the classifier to the divider 23, either together with the grinding stock 7 discharged from the tube mill.
  • the divider 23 can be adjusted again so that it generates two equal large subsets, which are fed to the two grinding chambers 20a, 20b of the tube mill.
  • the grinding chambers of the tube mill 20 are provided with grinding balls having a diameter of ⁇ 25 mm.
  • the ratio of length to diameter of each individual grinding chamber 20a, 20b is preferably less than 2.2. In the experiments on which the invention is based, it has been found that a ratio of length to diameter of ⁇ 2.0 or even ⁇ 1.7 is particularly efficient.
  • the tube mill 20 described above enables a high throughput and is compared to two separate mills to operate much cheaper and more energy efficient.
