Definitions

  • the invention relates to a device (according to the preamble of claim 1) for feeding material of different grain to a plant part, in particular a comminution machine.
  • the material to be comminuted is fed to the grinding chamber via a material feed chamber designed as a chute or shaft, from which the entire material supplied reaches the region of the comminution members.
  • the material crushed in the grinding chamber, together with the fine fractions already contained in the feed material, is then pneumatically fed to a classifier arranged above the mill.
  • the invention is based on the object of designing a device of the type required in the preamble of claim 1 in such a way that a substantial increase in performance of the system part downstream of the material feed device, in particular a comminution machine, is achieved.
  • the fine fractions contained in the feed material are sighted out of the feed material by means of an air stream already in the material feed space, ie even before reaching the downstream plant part (for example a comminution machine), and bypassing the plant part to the finished product guided.
  • the downstream plant part for example a comminution machine
  • the idea of the invention can advantageously be used in system parts operated with negative pressure, in which the air stream used to classify the feed material is sucked into the material feed chamber from the surroundings.
  • the invention can also be used in system parts which are operated with normal pressure or under positive pressure.
  • a fan is used to guide the air flow used to classify the feed material to the material feed chamber.
  • the plant part loaded with the pre-sifted feed material can be a comminution machine, for example a roller mill or a material bed roller mill.
  • a comminution machine for example a roller mill or a material bed roller mill.
  • the material feed space is generally formed by a material feed chute and in the case of a material bed roller mill by a material feed shaft.
  • the plant part loaded with pre-sifted material can also be formed by a sifter, for example.
  • a sifter for example.
  • Vor sighting to a significant relief of the classifier which results in a considerable increase in performance and an improvement in the selectivity.
  • the roller mill schematically illustrated in FIG. 1 with an integrated classifier contains, in a housing 1, a roller mill 2 (only shown schematically) (with an annular grinding path 3 and drive 4) and a static classifier 5 with guide vanes 6, coarse material cone 7 and pendulum flap 8.
  • the material to be shredded is fed to the roller mill 2 via a material feed chute 9 to which two air inlet ducts 10, 11 are connected in the region of the bottom of the sloping lower chute part.
  • the lower inlet openings of these air inlet channels 10 and 11 are provided with slides, as shown in FIGS. 2 and 3 in detail.
  • the air inlet opening 10 a of the upper air inlet duct 10 is limited by means of two laterally (arrows 12) adjustable sliders 13, 14. By adjusting these sliders 13, 14, not only the size but also the spatial position of the effective air inlet opening 10a can be set.
  • the size of the air inlet opening 11a of the lower air inlet duct 11 can be adjusted by means of a slide 15 which extends over the entire width of this air inlet duct 11.
  • a gas stream (arrow 16), preferably furnace gas, is drawn in through a nozzle ring 18 by means of a fan connected to the nozzle 17 of the housing 1 and, together with the one discharged over the edge of the grinding track 3, is sufficiently comminuted Well directed to classifier 5 (arrows 19).
  • the coarse material precipitates in the classifier 5 and is returned to the grinding path 3 via the cone 7 and the pendulum flap 8, while the fine material leaves the classifier through the nozzle 17 (arrow 20).
  • the material feed chute 9 through the feed material passing through the material feed chute 9 (arrow 21), two air flows are sucked through in cross flow, which are fed through the air inlet channels 10 and 11.
  • the fine and ultra-fine fractions contained in the feed material are detected by these sifting air flows (arrows 22, 23) and, together with the material sufficiently comminuted by the roller mill 2, are fed directly to the classifier 5.
  • the fine and ultra-fine fractions already aligned in the material feed chute 9 in this way from the material supplied do not take the detour via the roller mill in this way, but are fed directly to the finished product via the classifier 5.
