Definitions

  • the invention relates to a mill according to the principle of comminution by means of gas vortexes according to the preamble of claim 1.
  • Such a mill is also known as an eddy current mill or impact mill.
  • the term mill means in the following a working mill on this principle, as for example from the DE 27 36 349 A and the DE 197 00 429 A is known.
  • designs with a cone-shaped stator have a relatively easily adjustable grinding gap compared to those with a circular-cylindrical stator.
  • Location designations refer in the following to a mill whose rotor axis of rotation is vertical and whose inlet is located at the top. In practice, other layers of the mill are possible.
  • additives must be added to the material after milling, such as Borax or boric acid to paper, which is used as an insulating material.
  • Borax or boric acid to paper which is used as an insulating material.
  • additional devices with the corresponding effort are required in the known mills.
  • a known mill air inlets are arranged in the lid of the receiving housing.
  • the object of the invention is to provide a mill in which the quantities of air required for milling and for the transport of air are separately adjustable, which works clog-proof, the simple dosing of additives after the Grinding allowed and with respect to the temperature is gentle on the product or allows easy drying without the disadvantages of DE 22 06 384 A in terms of flow conditions to accept.
  • the object is solved by the characterizing features of claim 1. Characterized in that an opening is arranged in the jacket of the receiving housing in addition to the opening for the outlet, a portion of the required for grinding and transporting the total air flow can be supplied after grinding, without being passed through the grinder. This makes it possible to adjust the air flow required for grinding optimally and independently of the air flow for the clog-free transport, which is usually much larger and thus decisive for the total air flow.
  • relatively cold air can be supplied immediately after grinding through the opening according to the invention. This causes a rapid cooling of the ground material to a harmless temperature.
  • heated air may be supplied if post drying drying is required.
  • Additives can simply be introduced into the opening via a metering line, e.g. be gedüst and are then in the receiving housing of the mill, in which high turbulence prevail, intimately mixed with the ground Good.
  • the variability of the size of the opening allows the optimum adjustment of the air flow, which is supplied after leaving the grinding zone, depending on the good and the throughput.
  • FIG. 1 To FIG. 1 are mounted on a machine frame 1 with feet 2, a mill 3 and a motor 4.
  • the mill 3 is essentially constructed of a receiving housing 5, a stator 6 and a rotor 7.
  • the receiving housing 5, in the FIGS. 2 and 3 is shown as a detail, is rotationally symmetrical in plan and consists of a welded construction. It consists essentially of an outer cylindrical jacket 8, which is arranged vertically and on the internals and at the lower end inside an annular disc 9 are fixed as a bearing surface. As internals, a cylindrical ring 10 with attached annular disc 11, which is arranged vertically within and spaced from the jacket 8, and arranged as a connection, a horizontal bottom 12 with the jacket 8. The attachment between shell 8 and bottom 12 is stabilized with suitable means, not shown. Between bottom 12, casing 8, ring 10, washer 11, a bearing housing 22 and each of the lower edge of the rotor 7 and stator 6, an annular channel 18 is limited. In the jacket 8 are radially spaced two rectangular openings 13, 14 are arranged.
  • the one opening 13 is formed as an outlet with a cuboid outlet tube 15, which is arranged outside of the opening 13.
  • a vertical wall of the outlet tube 15 is attached tangentially to the jacket 8.
  • the other opening 14 is formed as an air inlet, arranged in the direction of rotation of the rotor 7 behind the opening 13 and provided with an externally mounted nozzle 16, to which a device 17 is fixed with a variable opening cross-section.
  • the opening 14 extends from the top edge of the bottom 12 to a height approximately corresponding to the top edge of the ring 10 and is about twice as wide as it is high.
  • device 17 e.g. a slide or a flap suitable.
  • a dosing line 34 for additives (additives) can be arranged on the connection piece 16 or in a pipeline possibly upstream of the flow direction.
  • a partition 19 is vertically arranged in the channel 18 so that it leads tangentially from the ring 10 and parallel to the outlet tube 15 to the side of the outlet tube 15, which is the opening 14 closest.
  • a plate 20 is guided perpendicular to the jacket 8 between the ring 10 and the jacket 8.
  • the plate 20 extends from the partition wall 19 to a length corresponding to about 15 ° behind the opening 14, in which case the extension of End edge through the center of the mill 3 runs.
  • the plate 20 has a slope such that an imaginary extension of the plate 20 in the direction of the slope at the outlet 12 cuts the bottom.
  • a vertical air baffle 21 is arranged between the bottom 12 and the plate 20. It extends over about its half length straight from the end of the plate 20 which faces away from the opening 13 in the direction of the opening 13 and then bent in a circle over about 80 ° to the opening 14.
  • the one end of the air baffle 21 is approximately 1/5 of the width of the bottom 12 away from the jacket 8, the other has approximately the same distance to the next side of the opening 14th
  • the bearing housing 22 is mounted on the disc ring 11.
  • a shaft 23 is rotatably mounted.
  • a pulley 24 is fixed, which is drivable via a plurality of V-belt 25 and the pulley 26 which is fixed to the drive shaft of the motor 4.
  • the rotor 7 is fixed. On the outer circumference of the rotor 7 a plurality of grinding media 27 are mounted in four levels. Above and below the rotor 7 is limited by a respective disk 28, 29. The rotor 7 with the grinding bodies 27 has the contour of a truncated cone. On the discs 28, 29 Vorzerkleinintechnikstechnikmaschinemaschinemaschinee 30 and fan blades 31 are attached.
  • the stator 6 is mounted indirectly on the jacket 8 and connected to e.g. Fastened screws. Between jacket 8 and stator 6, a sleeve is arranged in each case around a screw shaft as a spacer. In the stator 6 a replaceable armor 32 is attached, which is possibly constructed of several individual parts. The armor 32 has a corrugation, which runs approximately perpendicular to the rotation of the stator 6. In the lid region of the stator 6, an inlet opening 33 is arranged centrally.
  • the material is input via, for example, a pipe, not shown, in the inlet opening 33 and ground in a known manner between the grinding media 27 and the armor 32.
  • the milled material together with a respective air flow defined according to the material is discharged through, for example, a fan, not shown, from the mill 3, which is connected to the outlet pipe 15 via piping and a separation device (not shown).
  • the grinding gap is adjustable.
  • different lengths of the sleeves can be used, on which the stator 6 is mounted as a spacer.
  • the residence time of the goods in the milling area for the grinding result prevails, which in turn depends on the air flow, which is pulled through the grinding area.
  • the opening 14 and the device 17 it is possible to adjust this air flow independently of the total air flow, which is conveyed by the fan.
  • the cross section of the device 17 is changed so that adjusts the optimal air flow through the grinding area in dependence on the through the opening 14 in accordance with the flow resistance.
