  • Such mixing machines are industrial mixers which are used for mixing, in particular, bulk material, typically powdered bulk material, such as is required for producing plastic granulate mixtures or else in the paint industry. These mixing machines have a comparison with a frame pivotally mounted mixing head, which also serves to seal a container containing the mix, which is connected to the mixing head for the purpose of mixing therein. After the container has been connected to the mixing head, a closed mixing container is formed from the mixing head and the container containing the mix. For the purpose of connecting the container At the mixing head, the mixing head has one or more connection elements, for example a peripheral flange. Due to the fact that in these mixing machines a container containing the mix is connected to the mixing head, these mixers are also addressed as a container mixer.
  • the mixing head itself is pivotally arranged relative to the frame of the mixing machine, so that the mixing with respect to the mixing head in an overhead position, in which the mixing head at the bottom and the container connected thereto are located at the top.
  • Such known container mixers have a device for generating a Mischgutstroms.
  • Mischgutstromerzeugungs adopted used in conventional mixers axially mounted in the mixing head tool, driven by rotation motor.
  • Such a tool has a plurality of radially projecting from the drive shaft wings, so that it is designed in the manner of a propeller.
  • Such a container mixer is off EP 0 225 495 A2 known. Further, it can be provided to arrange a plurality of such tools on the drive shaft. In the prior art mixers, this tool serves as a mixing tool and generates a Mischthrombus during operation of the mixer with the mix contained in the mixing container.
  • a second motor-driven mixing tool is arranged radially engaging in the wall portion of the container.
  • This tool is a significantly higher speed rotating tool compared to the rotational speed of the tool used to create the mixing turret. It can be provided that several such are provided radially arranged mixing tools.
  • the at least one mixing tool is used for further energy input into the mixing thrombus generated by the conveying tool and for improving a particle dispersion and thus for supporting the mixing process.
  • the formation of the high-energy mixed thrombus is imperative for the mixing process.
  • the particles are conveyed in the mixing thrombus depending on the mix at a speed in the range of about 20 m / sec.
  • the aim is to achieve the desired mixing in the shortest possible time. Even if with higher tool speeds basically a thorough mixing in a shorter time is possible, as with slower rotating tools is generally considered that in the material to be mixed not too much heat may be entered. Especially when mixing plastic granules is to pay attention to this, otherwise the individual granules particles baked together and / or can also cake on the tools. For this reason, in the mixing machines described above, the mixing time is limited in order to prevent the mixed material from being too much heated by the drive of the first and second mixing tools as well as the jacket friction of the particles on the inner wall of the container.
  • the invention is therefore the object of an initially mentioned method and a mixing machine mentioned above to improve such that not only by a lower temperature input a gentler mixing is possible, but also that the mixing process is better controlled.
  • This procedural object is achieved according to the invention by an initially mentioned, generic method by means of Mischgutstromer Wegungs founded a low-energy Primärmischgutstrom as a flow for supplying the mixed material contained in the mixing container to the at least one mixing tool is generated by which mixing tool a only a fraction of the mixing container located mixed mixture detecting, but responsible for the actual mixing process SekundärMischgutstrom is generated as a cross-flow to serving as a flow primary Mischgutstrom.
  • the device-related object is achieved by an aforementioned generic mixing machine, wherein the Mischgutstromer Wegungs adopted for generating a low-energy Primärmischgutstroms arranged as a flow for supplying the mixed material contained in the mixing container to the at least one in the mixing head in the primary mixed material flow generated by the Mischgutstromer Wegungs worn intervening Mixing tool is designed and that the at least one mixing tool for generating a comprehensive only a fraction of the mixed material contained in the mixing container secondary stream of secondary material is provided as a cross-flow to the Primärärmischgutstrom.
  • the special feature of this method and a mixing machine designed in this way is that the process of mixing is always carried out on only a fraction of the mixing material contained in the mixing container, wherein the mixed material is successively supplied to the one or more mixing tools by the Mischgutstromer Wegungs adopted for generating the Primärärmischgutstromes as a flow ,
  • the orientation of the secondary mixed material flow is transverse to the flow direction of the primary mixed material flow, wherein the primary mixed material flow is designed, so that successively and repeatedly the mixing material contained in the mixing container is supplied to the mixing tool or tools for carrying out the actual mixing.
  • This concept has the advantage that the intended as a flow Primischischgutstrom can be generated with a minimum of energy input into the mix, since this stream basically serves only the purpose of promoting the mix contained in the container to the mixing tools or. Since the at least one mixing tool is provided for generating a secondary mixed material stream comprising a mass of material comparably small in comparison with the primary mixed material stream, the mixing tool can be designed to be correspondingly small in construction and with a correspondingly smaller dimensioned drive. In addition, this concept allows that several mixing tools can be arranged in the path of the primary mixed material flow, all of which work according to the aforementioned principle. If several such mixing tools are provided, they can be designed differently with regard to their tools.
  • the mixing tool is a dispersing tool with which a higher or higher energy secondary mixed material flow is generated, the energy input into the mixed material flow is relatively low even in such an embodiment of the mixing tool.
  • the particles which form the secondary mixed material stream only stay in the latter for a certain period of time before they, as a consequence of the conveying process, remain in this particle of the primary mix stream are brought out of the secondary mix stream.

  • the blade is guided in the radial direction with respect to the shaft of the conveying tool on the outside of the respective shaft or of the or the tools of the mixing tool.
  • the delivery tool is designed to clear the ground, so that no sediment accumulates on the bottom of the mixing container in the mixing position of the mixing machine, which is not supplied to further mixing.
  • a designed as Bodenschreibr conveyor tool has according to an embodiment of at least one helical segment-like designed conveying arm, which is arranged in the radial direction with respect to the shaft of the tool on the outside of the or the mixing tools mention 2009bar.
  • the at least one blade of the conveying tool preferably has a recess pointing inwards in the radial direction, while the blade itself extends into the extends the region near the shaft of the conveying tool.
