Definitions

  • the invention relates to a method according to the preamble of claim 1, furthermore a system for performing this method.
  • a method of the type required in the preamble of claim 1 is known from European patent application 00 84 383.
  • the amount of the semolina returned from the classifier to the grinding system is subject to certain fluctuations.
  • the invention is based on a method in which the rollers of the roller mill rotate at a constant speed, so that simple, uncontrolled drives can be used.
  • the invention is based on the object of designing a method of the type required in the preamble of claim 1 in such a way that optimal comminution ratios in the roller mill and in the downstream mill are ensured with a comparatively low system outlay.
  • the system contains a roller mill 1, a downstream second mill 2, which is designed, for example, as a ball mill, and a classifier 3.
  • the regrind is fed from a storage hopper 4 via a dosing belt scale 5 to the feed shaft 6 of the roller mill 1, which contains two driven rollers 7, 8, which form a roller gap 9 between them.
  • the ground material comminuted in the roller mill 1 passes via a conveying element 10 to the second mill 2, where the agglomerates formed in the roller mill 1 are dissolved and possibly further comminuted.
  • the material discharged from the mill 2 is fed to the sifter 3 via a bucket elevator 11, from which the finished product (arrow 12) and semolina (arrow 13) are drawn off.
  • the semolina (arrow 13) arrive at a distributor device 14 and from here partly back to the feed side of the mill 2 (arrow 15) and partly (arrow 16) to the feed shaft 6 of the roller mill 1.
  • a second control loop is used to keep the fill level in the feed shaft 6 of the roller mill 1 constant, regardless of fluctuations in the quantity of fresh material (arrow 20).
  • This control circuit contains a controller 21 which receives a signal corresponding to the respective fill level in the feed chute 6 via a fill level measuring device 22 (for example operating on an ultrasound basis) and an element 23 and which delivers a corresponding control signal via an element 24 to the distribution device 14.
  • the controller 21 in this case increases the portion of the semolina via the distributor device 14, which portion is returned to the feed chute 6 (arrow 16).
  • control processes run in the opposite direction.
  • the two rollers 7 and 8 of the roller mill 1 are driven by uncontrolled simple drives 25, 26 at a constant speed.
  • rollers 7, 8 are driven in the illustrated and described exemplary embodiment, it is also possible within the scope of the invention to drive only one of these rollers, preferably the fixed roller.
