Definitions

  • the invention relates to a Um dvslzmahlstrom, comprising: at least two roller presses for crushing the ground material, at least two first classifiers for prospecting a coarse grain fraction, at least one second classifier for prospecting a fine grain and a medium grain fraction of the selected in the at least two first classifiers fractions, wherein a in the Umisselzmahlstrom abandoned feed material which passes at least two roller presses and the at least two first classifier and then the at least one second classifier and the middle grain fraction and the coarse fraction of at least two first classifier is again given to the roller presses, and wherein the at least two first classifier below the at least two roller presses are arranged.
  • Such Umisselzmahlstrom is off DE 102006004282 known.
  • the object of the invention is therefore to provide a Um dvslzmahlstrom available, which has low space requirements and yet easy to maintain.
  • the invention is achieved in that a transport of the fractions located in the at least two first classifiers is provided by at least two risers, wherein the at least two roller presses are arranged between the at least two risers.
  • riser pipes for the circulation of the ground material so that the roller presses are arranged within the arrangement of the riser pipes, ie between them.
  • the inevitable external arrangement of the risers allows a common use of a single lifting crane for the maintenance of roller presses, For example, to exchange the individual rollers of the roller press.
  • this arrangement allows the simultaneous use of risers as supports for a hall assembly for weather protection of the system.
  • the outer risers are mainly due to their placement at statically favorable locations, for example on the roller press platform, to take over a supporting function for a roofing element, so that specially constructed supporting elements for a system hall dispensable, but at least smaller dimensioned.
  • roller presses 14a and 14b are loaded with a mixture of fresh, medium and coarse material and in turn have items which are described by the roller press 14a.
  • the inventive arrangement of the various roller presses 14a and 14b a number of different advantages are achieved, which will be discussed in more detail in the text.
  • the component parts of the roller press 14a are the machine frame 141, the roller bearings 15a and 16a, and the grinding rollers 17a and 18a.
  • roller press 14a After the mixture of fresh, medium and coarse material the nip between the Grinding rollers 17a and 18a has happened, being shown in the drawing roller press 14a in the maintenance state, roller press 14b in the working state, the comminuted grinding material is excreted down from the roller press 14a again.
  • pressing slugs are formed from shredded regrind, which are disagglomerated in the next unit of the plant.
  • the static V-classifier 40a separates by means of classifying air 19a the grinding material flow 21a emerging from the roller press 14a, the coarse material discharge 20a being recirculated back into the roller press.
  • the fine fraction separated in this classifier 40a is pneumatically transported by the classifying air stream 19a, as indicated by the dashed arrows, up through the riser pipe 30a to a level above the roller press 14a. There, this fine material enters the rod basket classifier 11 mentioned above, where the fines from the V classifier 40a are separated into a middle fraction and into a fine fraction.
  • the fine material stream 22 then leaves the rod basket sifter by an unspecified arrangement, which is indicated by an arrow to the top right.
  • the separated in this rod basket separator 11 Mittelgutstrom is divided into different Mittelgutströme 13a and 13b and fed back to the various roller presses 14a and 14b.
  • roller presses 14a and 14b are arranged between at least two riser pipes 30a and 30b. As a result, a structure of the entire system is achieved, which allows items to move due to wear requiring maintenance roller presses 14a and 14b using only a single, centrally located lifting crane 20.
  • the roller presses 14a and 14b are arranged on a platform 35 in the rotary grinding plant 10, which allows the roller presses 14a and 14b from their working position in which they deliver the ground material leaving them down to the respective existing V-classifier , Can be moved to the maintenance position in which the grinding rollers 17a and 18a can be lowered by means of one and the same lifting crane from this stage.
  • the circulating grinding plant 10 in FIG. 1 is in FIG. 2 in the plane passing through the line AA in FIG. 1 is indicated and perpendicular to the paper plane, shown.
  • the Umisselzmahlstrom described here 10 has four roller presses, which are each arranged below the rod basket sifter 11.
  • the riser pipes are arranged at the corners of a rectangle. But it is also possible to choose a different polygonal arrangement of different roller presses. When using two roller presses they are in line, with the use of three or more roller presses, these are advantageously arranged at the corners of each corresponding to the number of roller presses polygon, each roller press has its own riser.
  • FIG. 3 Finally, a Umnachlzmahlstrom from the prior art is shown, in which a central riser is used to transport the originating from different roller presses and pre-sighted ground for the circulation up. Due to the central arrangement, this construction is not suitable for attaching a roof for weather protection directly to the riser construction, which is why it is necessary to construct a roof around this plant. Furthermore, a hoisting crane has to approach from different sides for the maintenance of the roller presses. For this purpose, it is necessary to provide suitable traffic routes for a mobile crane or more than one crane must be kept for maintenance of the system, which leads to an increase in the cost of the entire system.
  • FIG. 3 shows a broken-away view from above of a rod cage sifter 45 in a special embodiment of the invention which the Umisselzmahlstrom invention 10 offers particular advantages.
  • the invention proposes to grind the different materials in at least close to closed circuits within the Umicalzmahlstrom.
  • the different components on different roller presser-Sichterfinde give up, these roller presses and classifiers are matched to the grinding of the individual regrind by nip pressure, gap size, intensity and temperature of the classifying air, size of roller presses and / or classifier in addition to other specific parameters.
  • the different millbase passes through the Ummélzmahlstrom with a common second classifier in which the separated fines of both roller presses is mixed and withdrawn, while the Mittelgutfr hopeen the different components remain in separate circuits.
  • the two fine fractions 62 and 72 are mixed within the bar basket and in the following gas path during the discharge.
  • separate circuits for each roller press 14 a and 14 b, the corresponding corresponding first classifiers 40 a and 40 b, the various risers 30 a and 30 b and within the common Stabkorbsichters form.
  • An advantage of this configuration is that in the different closed circuits different grindable components can be ground individually, each roller press can be adjusted to the grindability of the material passing them.
  • the corresponding to the roller presses first classifier can be adjusted so that an optimally adapted sighting takes place. Only the fine fractions 62 and 72 are intimately mixed with each other after separate grinding by suspension in the classifying air, so that a high-quality mixed product is formed.
