- the ejection chambers keep their shape axially downwards and are open on the lower face of the rotor.
- the ejection chambers have seen from the lower planar surface upwards, at the rotor outer diameter preferably a smaller depth than the inner cavity diameter of the rotor.
- the ejection chambers of the rotor are connected via the horizontal, planar annular surface of the grinding chamber with the inner annular space, wherein the annular-cylindrical -Mahlraum and partially the flat, annular surface-shaped grinding chamber are filled with grinding beads.
- the grinding material feed space arranged upstream of the grinding space is arranged with the grinding access around the stirring shaft in the upper centric area and is provided with the feed impeller, so that the grinding material flow with support of the tools in the feed space on the conical surface of the rotor conveys into the ring grinding space can be.
- a dispersing disk When used with a dissolver, a dispersing disk can be fastened to the stirrer shaft below the immersion mill in a stirred vessel. The dispersing disk thus sucks in the material to be ground through the separating sieve.
- the size of the rotor, the formation and / or arrangement of the tools, the rotational speed of the shaft and / or the performance of the dispersing disc are coordinated so that the millbase Mahlperlen stream in the ejection chambers of the rotor largely freed by the centrifugal forces of grinding beads occurring is, so that the millbase can flow unhindered through the separation screen of the dip mill in the stirred tank, wherein the rotating dividing screen is equipped in the center of the dip mill at its lower end with a gap seal to prevent leakage of the beads.
- the outer housing of the dip mill is double-walled, so that a cooling in the grinding container is arranged to cool the material to be ground.
- Another part of the invention is a dissolver with a stirrer shaft, at the end of which a dispersing disk is located, with a drive that drives the stirrer shaft, which is intended to extend into a stirred tank, wherein a submersible mill as described above on the stirrer shaft and attached to the housing of the dissolver.
- dip mill is a corresponding part of the invention.
- the invention has a good product introduction into the grinding chamber. Furthermore, the invention prevents the leaving of grinding beads through the open Mahlgutzugang.
- the invention has a high, uniform energy density in the entire annular grinding chamber.
- a further advantage regardless of the size of the mill, is a comparable cooling capacity corresponding to the size, the grinding capacity being linear with respect to the size of the machine.
- the sieve allows for very small grinding beads and protects itself by its rotary motion.
- the seal (grinding bead retention) is designed so that it can absorb dimensional tolerances, thermal expansion, radial shocks and wear.
- the invention manages with less than 50% of the grinding beads of a conventional full-space immersion mill and achieves a higher grinding performance than these.
- Fig. 1 shows a section through the present invention with a submersible mill 5, which is driven by a rotating stirrer shaft 3.
- the shaft in turn is driven by a drive 1, usually an electric motor with or without gear.
- This dip mill 5 is guided in a stirred container 29 and thus is located in a ground material 2.
- the ground material 2 flows from above into the dip mill 5, being accelerated at an inlet / Mahlgutzugang 9 by an impeller 27, of blade-shaped tools 13, preferably pins 13, detected on the conical surface of a rotor 12 and guided into a grinding chamber 7. Wherein it is sucked by a dispersing / pumping disk 4 below the dip mill 5 through a separating wire 10 and thereby obtains its strongest orientation.
- the complete mill (immersion mill) 5 submerged in the material to be mixed / ground material 2 is achieved in comparison to the known, closed full-space and annular space agitator mills (see US Pat DE 3844380 C1 . DE 3716587 C1 . DE 4240779 C1 ) an open, non-pressurized system, such as the submersible mill 5 in the mixing vessel 29 itself.
- the agitator mills with an external pump the ground material in The grinding room pressed, from which it can then flow out after grinding in the non-pressurized (atmosphere) space. So it is in the dip mill a completely different flow behavior of the ground material and grinding beads - Mahlgutmasse compared to the known Rlickwerksmühlen given.
- Fig.2 how out Fig.2 can be seen, is by the annular cylindrical configuration of the grinding chamber 7 with a relatively small volume of the invention submersible mill over the entire mills - interior or comparatively full room mill (see submersible mills DE 10 2009 013 214 B3 ) in a significant advantage, since only a small amount of grinding beads 8 are needed.
- annular grinding chamber 7 which, of course, presupposes that a regrind positive guidance is provided in this annular grinding chamber 7 and can not get from the access to the exit as in the case of conventional dip mills by the shortest route.
- a feeding of the ground material is carried out by a Mahlgut feed space 26.
- the annular cylindrical design of the grinding chamber 7 is achieved in particular that the grinding beads 8 only small radial paths in the grinding chamber, since they held by exploiting the centrifugal forces occurring in this outer, cylindrical grinding chamber 7 or gather after a machine start-up in this area.
- the rotor 12 In order to better bring in this motion beads compressed ring grinding chamber 7, the kinetic energy of the rotor 12 in a Mahlgut MahlSystemmasse or Mahlperlenmasse 24, the rotor 12 is also provided on its outer cylindrical surface with stirring tools, preferably with pins 13, the grinding beads put into a strong turbulence, so that between these grinding beads and between grinding beads and Mahlraumbegrenzung and the grinding beads and the tools 13, the grinding or dispersion of the ground material takes place.
- tools preferably pins 13, are attached to the resting cylindrical inner wall 14 of the grinding chamber, which brakes the rotating grinding material mass 24 and causes additional turbulence, ie kinetic energy ,
- Fig. 2 is good to see that the cylindrical inner wall 14 is designed double-walled to the outside to dissipate, if necessary, with a suitable cooling medium 16, preferably water, heat energy.
- a suitable cooling medium preferably water, heat energy.
- This outer annulus / grinding chamber 7 (see Fig. 2 ) is turned inwardly by the cylindrical rotor 12 (see Fig. 2-5 ) formed on the vertical stirrer shaft 3 is formed. At its lower boundary, the rotor 12 has a flat annular surface 17, which in turn delimits this downstream grinding chamber 23 upwards. This ring surface of the rotor is also equipped with stirring tools ( Fig. 2 . 3 .
- the ejection chambers 18 have such a strong widening toward the rotor center that the few grinding beads in the inner annular space 19 (dimension B) around the separating screen 10, during the rotational movement or centrifugation in the interior of the rotor 12 find no support and again in the outer Ring - grinding chamber 7 flow back.
- the ejection chambers 18 are recesses in the body of the rotor 12.
- the dividing screen 10 is spaced around the agitator shaft 3 and the hub of the rotor 12 is disposed, and is easily releasably secured to the inner, upper planar surface and rotates with the rotor 12 about the common axis.
- the dividing screen is usually a slotted screen, in which a profile wire is wound spirally with a defined distance as a cylinder. The individual spiral turns are fastened to rods in the interior, which are arranged axially (see DE 3844380 C1 . DE 3716587 C1 . DE 4240779 C1 ). Since also act on the Siebmantelification by the rotational movement centrifugal forces, this separator 10 is largely free of grinding beads 8 or cleans itself largely.
- a seal according to Fig.2 is referred to as a gap seal 11 in a preferred embodiment and is arranged in the lower region of the rotating separation screen 10. It is from the construction largely a classic mechanical seal. In one possible embodiment, this serves only as retention of the grinding beads 8 and does not have to be dense. Therefore, the term gap seal 11, as it allows a small separation gap (opening gap). As a special feature, the gap seal 11 is able to absorb axial dimensional inaccuracies and the different thermal expansion of the stirrer shaft 3 and of the support rods 20 of the submersible mill 5. It is also able to keep their separation gap dimension easily in the radial shocks of the agitator shaft 3.
- the sliding ring is also able to compensate for the resulting wear.
- a hard material such as carbide in the mating ring 22 in the bottom area against the rotating, spring-loaded sliding ring 21 made of ceramic or preferably made of wear-resistant plastic.
- plastic it could be the material as it is already used today in lip seals. Again, it will open DE 10 2009 013 214 B3 directed.
- the plastics can be used in 20 2013 101 084.7 were called, which have a high inventory force during rotation, in particular suitable PE and PU, PTFE compound material, see above.
