Definitions

the invention relates to a classifier, in particular a cascade classifier, that is a device for separating particle streams with different Particle size, with an additional airflow to classify these two Materials is used.
FIG. 1 Facilities of this type, generally called wind sifters, consist of levels or annular cylindrical gap surfaces through which the product that is made Composes particles of different sizes, directed from above and air flows through from below at the same time.
the visual effect is now based on that the air flow is adjusted so that the product, which is the lesser Hovering speed by which air flow is carried upwards. It then exits the air classifier together with the air at the air outlet.
the Product that has the higher hover speed falls through the wind sifter through and out of it below.
the invention is therefore based on the object of a classifier, in particular a To create air classifier that avoids the disadvantages mentioned and in simpler constructive an optimal and dead space-free separation of the product guaranteed.
the main advantage of the classifier is that the cascade guide with zigzag shaped outer part and parallel inner part one Forms product path in which the surfaces clean themselves through the product.
Another embodiment of the invention provides for an orifice in the product inlet to arrange. This aperture concentrates the product flow towards the paragraph so that Even there, an equalization of the product flow is guaranteed.
an ion beam dispenser has proven itself this is according to a further embodiment of the invention above the Air classifier or mounted in the air classifier.
a magnetic separator to provide. This magnetic separator catches metallic particles, wherein it is arranged in an area that tears off the attached prevents magnetic particles due to the product flow. This will be so made that the magnetic separator is installed above the air classifier, where the annular inlet is reduced to a flat gap surface. For support of the separation effect, the magnetic separator is at an oblique angle to the Mounted vertically with the magnets attached to the side that are not be touched by the product.
the product stream is according to arrow 17 via the feed pipe 3 to the device fed.
the aperture 4 limits the total current so that a defined Product stream flows through the cascade air classifier. It divides after aperture 4 ring-shaped over the first cone of the inner container 2, according to arrow 18, 19 and falls from level to level through the cascade air classifier, being noticed when falling detach the next stage from each other.
a sight glass is located in the upper part of the air classifier to assess the visual effect 10 attached.
Ion beam dispenser 11 For products that are statically charged, one can according to FIG Ion beam dispenser 11 are installed, which discharges the product electrically, so that no electrostatic product build-up occurs in the air classifier can.
a so-called Magnetic separator 12 can be installed.
the round cross-section of the feed pipe changed so that the product through flows through a flat gap.
the magnets of the magnetic separator 12 are attached to one side of the gap and pull out magnetizable parts the product flow to the pipe wall, the parts remain there until they are in one Cleaning cycle manually or mechanically with appropriate tools will be cleaned. So that the product does not over the metal particles attached to the Adhering pipe wall, the flat, as shown in Figure 2, slides away Slit surface inclined from the vertical so that the product on the magnet flowing away from the gap surface.
