Definitions

  • the invention relates to a roller mill with edge elements for comminuting granular material, and to a method for operating a roller mill.
  • Roll mills are usually used for comminution of regrind, such as limestone, clinker or similar rocks.
  • regrind such as limestone, clinker or similar rocks.
  • edge elements For controlled influencing of the lateral outflow of ground material from a grinding gap formed between the grinding rollers of a roller mill, it is known to arrange edge elements on one of the grinding roller.
  • a roller mill with edge elements is known, for example, from DE 20 2014 006 837 U l.
  • On the edge elements acts an increased specific grinding pressure, which leads to a heavy load on the edge elements and thus often to wear or breakage of the edge elements.
  • a roller mill for comminuting granular material comprises a first grinding roller and a second grinding roller, which are arranged opposite one another and can be driven in opposite directions, wherein a grinding gap is formed between the grinding rollers.
  • At least one of the grinding rollers has an edge element at an end region of a grinding roller end, which is designed such that it extends over the grinding gap and at least partially covers the opposite grinding roller at the end.
  • a scraper element for removing material is arranged at the end portion of the grinding roller end provided with a peripheral element.
  • the scraper element is used in particular for the at least partial removal of material attached to the end region of the grinding roller. The material is stripped by the scraper element during operation of the roller mill, with the grinding rollers rotating in opposite directions.
  • the scraper element is preferably arranged at the end region of the grinding roller such that it does not touch the grinding roller.
  • the end region of the grinding roller comprises, for example, the end face of the grinding roller, the grinding roller surface adjoining thereto and a region surrounding the grinding roller surface in which material deposits.
  • a region has a height of more than or equal to 1.5 mm - 3 mm, in particular more than or equal to 2 mm - 5 mm, preferably 4 mm.
  • the edge element comprises in particular a circumferential circular ring, preferably a circular disk.
  • the edge element is attached to the end face of the respective grinding roller, for example screwed or welded.
  • an end-side gap is preferably formed in each case.
  • An end-face gap prevents a collision of the edge element with the end region of the respectively opposite grinding roller in the case of a skew of the grinding rollers, wherein the opposed grinding rollers are not arranged parallel to each other.
  • the grinding rollers comprise in particular a roller base body, wherein the edge element is detachably connected to the roller base body of the respective grinding roller.
  • the grinding roller preferably comprises a drive shaft for driving the grinding roller, on which the roller base body is arranged.
  • a detachable arrangement of the edge elements on the roller body offers the advantage of a quick and easy replacement of the edge elements in case of wear.
  • the edge elements are glued, soldered, welded or screwed, for example, on the roller body and preferably have wear protection.
  • the wear protection is arranged on the pointing in the direction of the grinding gap inner surface of the edge element.
  • Such wear protection includes, for example, a wear-resistant coating, such as build-up welding, wear protection elements or wear protection coatings.
  • the edge elements are formed of steel.
  • a material layer usually forms on the surface of the grinding rollers, which causes an auto-wear protection of the roller surface.
  • this wear protection layer is thicker at the end regions of the roll ends, which are provided with edge elements, than at the remaining regions of the grinding rolls. This leads to an increased grinding pressure, by which the edge elements are more heavily loaded and wear or fail more frequently.
  • the scraper elements of the material structure is reliably prevented at the grinding roller ends on the edge elements. This minimizes the risk of increased wear and failure of the edge elements.
  • the scraper element is arranged such that it removes material attached to the edge element and / or at the end region of the grinding roller during operation of the roller mill.

  • a distance between the scraper element and the edge element and / or the end region of the grinding roller prevents contact of the scraper element with the grinding roller and thus reduces the wear of the scraper element.
  • the scraper element is arranged according to a further embodiment such that the distance between the scraper element and the edge element and / or between the scraper element and the end region of the grinding roller is adjustable.
  • the thickness of the material layer at the end regions of the grinding rollers should not exceed a certain value of, for example, 1 to 30 mm, in particular 2 to 25 mm, preferably 5 to 10 mm.
  • An adjustable distance ensures that the distance between the wiper element and the edge element and / or the end region of the grinding roller is kept constant during wear of the wiper element. In addition, the life of the wiper element is extended and replacement is not necessary in case of wear.
  • the roller mill has a stationary machine frame and the wiper element is attached to the machine frame.
  • machine frame includes a plurality of frame members connected to bearing stones of the grinding rollers so that the grinding force acting on the grinding rollers is transmitted to the machine frame.
