Definitions

  • the invention is directed to a two-roll machine, in particular a high-pressure roll press for pressure treatment of granular goods, with two rolls driven in opposite directions and separated from one another by a roll nip, a feed chute being arranged above the roll nip.
  • the invention further relates to a method for operating such a two-roll machine.
  • the bulk material fed to the nip is gripped by the oppositely driven rollers and drawn into the nip by friction (friction within the bulk material and friction between bulk material and the roller surface).
  • the individual particles of the drawn bulk material are mutually crushed in a material bed, ie in a material bed compressed between the two roller surfaces when using extremely high pressure, so that one speaks of the so-called material bed comminution (DE-PS 27 08 053).
  • the product of this pressure treatment are agglomerates made from shredded bulk material, which can then be broken down with little mechanical effort.
  • the air that was originally present in the bulk material is pressed out of the bed. It escapes through the material column formed from the bulk material against the direction of the material flow, as a result of which the bulk material is loosened up considerably in the feed area of the rollers then, when fine-grained bulk goods are pressed, with the result that the material feed deteriorates and the throughput and the degree of comminution are reduced.
  • DE-OS 38 06 398 proposes to subdivide the feed hopper and to feed the coarse and fine material separately to the roll gap, the bulk material bed being kept so low that the air pressed out by it low and large pore fill can easily escape.
  • a disadvantage of this known method is that it can only be used if the coarse material and the fine material are present separately from one another before the pressure treatment and furthermore that the possibility of forming an inhomogeneous material bed cannot be ruled out by the separate feeding of coarse and fine material can.
  • the invention is therefore based on the object, a two-roll machine, such as. B. high-pressure roller press, with an improved feed behavior while avoiding the disadvantages of known device.
  • the bulk material in this widened part can form an embankment in the free flow according to its angle of embankment, as a result of which a free space is formed between this embankment and the walls of the feed chute.
  • the air emerging from the bulk material embankments can be supplied to a dedusting device via a suction line. Due to the negative pressure that forms in the free space above the bulk material slope, the air outlet from the bulk material is additionally favored at this point.
  • FIG. 1 there is a feed chute (12) above the rolls (10, 11) of a two-roll machine.
  • the side wall (13) arranged in the axial direction of the roller is offset parallel to the upper side wall (14), as a result of which the lower part of the feed chute (12) is widened.
  • the lower part of the feed hopper (12) is arranged centrally above the nip (15) formed by the two rollers (10, 11).
  • the bulk material forms an embankment (16) in the lower part of the material feed shaft, through which the air (17) escapes into the space formed by the bulk material and the walls of the material feed shaft (12), from where it does not lead to a suction line (18) shown dedusting device is suctioned off.
  • the height of the embankment can be changed by means of an adjustable slide (19) and thus the different feeding behavior of the bulk material can be adapted.
  • flaps (20, 20 ') in the lower widened part of the feed hopper (12), as shown in FIG. 3, allows the free inflow of bulk material which is caused by the formation of the embankment (16) to be braked again in a controlled manner are, so that here a finely tuned control unit for optimal coordination of the intake behavior of the bulk material is available.
  • the flaps (20, 20 ') create new slopes (21, 21') through which additional air can escape from the bulk material.
  • the feed hopper (12) according to FIG. 2 can also be provided with flaps (20, 20 ') according to FIG. 3.
  • the two-roll machine according to the invention can not only be used as a high-pressure roller press for pressure comminution of granular material, but it can also be used for pressure treatment, such as e.g. B. for the compaction of potash and / or rock salts or the like.
