Definitions

  • the invention relates to a viewing device for viewing a granular material flow.
  • a sifter It is known to divide granular material such as cement, cement-containing substances, slag, limestone or ores into a coarse and a fine grain fraction by means of a sifter.
  • classifiers are connected downstream of a material shredding device, such as a roller mill, for example, the coarse material emerging from the classifier being fed back to the material shredding device.
  • Known sifters are, for example, static sifters in which a coarse material sifting takes place via impact and guiding devices, and dynamic sifters in which a fine material sifting takes place, for example via a rotating rod basket. From the DE 10 2004 027 128 A1 a viewing device is known which has a static sifter and a dynamic sifter, the static sifter forming the first viewing stage and the dynamic sifter forming the second viewing stage.

  • the viewing device comprises a static sifter and a dynamic sifter, the static sifter being arranged in such a way that it at least partially encloses the dynamic sifter.
  • the classifier furthermore has a distributor device which is designed such that it feeds the material flow from the first inlet to the static classifier and feeds the material flow from the second inlet to the dynamic classifier.
  • Such a distributor device offers the advantage that at least two material flows of different grain sizes can be fed to the classifier, the material flow entering through the first inlet flowing through the static classifier and the dynamic classifier and the material flow entering the classifying device through the second inlet exclusively through the dynamic classifier flows through.
  • the viewing device preferably has one or a plurality of first and second inlets through which the material to be viewed enters the viewing device.
  • the material flow entering through the first inlet is, for example, a coarse-grained material relative to the material flow entering the classifying device through the second inlet.
  • This coarse-grained material can come from a roller mill or a material bed roller mill, for example.
  • the material flow entering the classifying device through the second inlet can, for example, be a material comminuted by means of a ball mill.
  • the described viewing device makes it possible to dispense with an additional viewing device for each of the material flows and, on the other hand, enables both material flows to be viewed by means of a single viewing device.
  • the granular material flow can in particular be cement raw material, cement, cement-containing substances, limestone, slag or ores.
  • a static sifter comprises a plurality of flow devices, for example guide vanes, which serve to deagglomerate the material flow flowing through the static sifter.
  • the static sifter is designed in particular in such a way that it forms a cylinder-ring-shaped sifting zone between the flow devices and the dynamic sifter is arranged within the static sifter.
  • the static sifter is fed via a sifting air duct, for example by means of a fan, sifting air, which is guided via the plurality of guide vanes of the flow device against the material flow flowing through the static sifter.
  • the coarser grain fraction of the material stream flowing into the classifier through the first inlet leaves the static classifier through a first outlet, the finer grain fraction of the material stream being conveyed to the dynamic classifier through the classifier air.
  • a dynamic sifter comprises a moving viewing zone, for example a rotatable rod basket, into which a material flow with a small grain size, in particular up to about 10 mm, enters.
  • the dynamic sifter is arranged, for example, coaxially to the static sifter and rotationally symmetrical to the drive axis of the moving viewing zone.
  • the material flow of medium grain size is rejected by the dynamic classifier and exits the classifier through a second outlet.
  • the material flow that passes through the dynamic classifier has a grain size of up to about 300 ⁇ m and emerges from the classifier through a third outlet.
  • the material flow entering the classifier through the second inlet is fed to the dynamic classifier via the distributor device, the material rejected by the dynamic classifier leaving the classifying device through the second outlet and the material that has entered the moving classifying zone of the dynamic classifier exiting the third outlet exits the viewing device.
  • the viewing device according to the invention enables two material flows of different grain sizes to be divided into three grain fractions.
  • the coarse grain fraction sifted in the static sifter can be fed to a first comminution device, such as a roller mill, while the middle grain fraction sifted in the dynamic sifter can be fed to a second comminution device, such as a ball mill. In this way, a particularly compact design of a classifier with a static and a dynamic classifier is achieved.

  • a circular configuration of one of the disks enables the disks to be arranged in parallel, with, for example, the first disk for feeding the material flow to the static classifier being arranged above the second disk so that the material flow entering through the first inlet through the second, upper disk onto the first slice falls.
  • This enables a particularly compact design of the distribution device.
  • first disk and the second disk are connected to one another via connecting means.
  • a connection of the first and the second disk realizes a simple drive of both disks via a drive shaft.
  • At least one of the first disk and the second disk of the distributor device has a plurality of guide elements on the surface of the disc.
