Definitions

  • the present invention is concerned with a Ent Scholl fürshiel with adjustable material bed thickness, with a stepped transport surface that works on the principle of the so-called sifter and can be installed both with discrete components in existing systems, as well as put together in modular design.
  • the present invention further relates to a method for deflaking.
  • the DE 10 2007 020 156 A1 discloses a Staurau, which is arranged transversely to the flow direction of the bulk material on a Siebbelag a screening machine.
  • the actual separation process of the material flow takes place essentially under water, wherein the Staurau has no Umnachlz Mann the material.
  • the plant according to this document is used for the separation of organic materials with lower density, such as wood or coal from a mineral mixture with a higher specific gravity.
  • the focus of this document is in the construction of the Stauancen, which are designed as nozzles, integrated into plug-in polyurethane screen documents.
  • a cascade-like chute which is divided into a plurality of stepwise arranged part levels over which the bulk material falls due to the gravity of the steeply inclined part levels of the chute down.
  • the bulk material is penetrated at a certain point by a gas stream, so that particulates dissolve from the bulk material and fed to a suction cup arranged above the principle of a cascade classifier an exhaust pipe.
  • the particles not captured by the gas flow pass through an extended chute into a collecting silo, where they are stored until further processing.
  • a device for the selection of rubble which discloses a substantially horizontal vibratory trough and a downstream air classifier for separating lightweight materials for separating the material.
  • This invention is characterized in that the bulk material falling from the vibrating trough is detected by the air flow of a vertical air classifier, whereby a large part of the dust content of the bulk material is separated, which is taken up by a vacuum conveyor and transported away.
  • a disadvantage of this device it is felt that the structure is technically relatively complicated and the degree of cleaning of the bulk material due to the relatively short residence time, the bulk material is exposed to the air flow is relatively low.
  • the secondary and tertiary primary stages are downstream. These then break the feed material into the classic, above-mentioned grits.
  • Each one Crushing stage downstream screening machines which classify the material in the desired grain sizes.
  • the multiple breaking of the rocks also produces fine dust ⁇ 0.09 mm, which is referred to in the industry as a "filler". These fine particles either adhere to the coarser grains or are contained as free fine material in the grain size 0-5 mm. For many applications, the amount of filler in these grains may not be greater than 5% of the total, since the fines are negative, eg. As in concrete, affects the strength.
  • the feedstock is introduced into a gas stream (usually air) in which the particulates fall or rise due to their specific gravity or specific surface area. That is, the heavy and thus coarse parts sink and the fine rise.
  • the rising, carried by the gas fines are usually eliminated by filter systems.
  • various systems such as countercurrent sifter, cascade classifier, cross-flow classifier and many more. All of these classifiers are based on the same principle of action. Due to the process, the classifiers require a high installation height and are very sensitive to high temperatures and high humidity. Therefore, they often need to be well insulated, which means additional investment needs.

  • the suction tubes 9 ' are arranged and adjusted in the region of the individual stages 8, 8' at a predetermined distance.
  • the amounts of gas in the ducts 4 and in the suction pipes 9 ' can be adjusted individually by throttle valves 29, 29' or valves at each stage of the machine, thus influencing the grain boundary in the finished material.
  • the polluted with particles and contaminated gas in the suction pipes 9 ' is then fed to a filter unit 15 in the upper part by an insertion nozzle 26, which cleans the gas loaded to clean gas according to the legal regulations.
  • the filtered-out particles 21 are discharged in a collecting container 24 by means of a worm drive 25 and stored at a suitable location.
  • the clean gas from the filter system 15 is fed via a transfer line 18 to a frequency-controlled blower 20, which feeds the clean gas via the line 18 'the gas inlet 19 again, so that in principle the purified gas is not blown into the environment, but is reused.
  • the part-transporting floors 3, 3 ' are mounted on crossbeams 12, which may consist of folded sheet metal, profiled steel or hollow sections.
  • the number of stages 8 is normally at least two. It is variable and depends on the feed material.
