Definitions

  • the invention relates to a stirred ball mill with a Separator for separation of KleinstmahlMechn with a Diameter D ⁇ 0,1mm from the product.
  • Agitator ball mills for example, for crushing and dispersing solids in a liquid phase or used for the digestion of microorganisms.
  • agitator ball mills have a cylindrical, horizontal or vertical axis grinding chamber with various types Separators for separating the grinding media from Product in the product outlet area.
  • the housing of the grinding chamber of a stirred ball mill consists from one longitudinal wall and two at the two ends of the Longitudinal wall arranged end walls. It has a Feeding the ground good serving inlet and a for Discharge of the good serving good outlet.
  • In the Milling chamber is also a rotatable about the chamber axis Agitator arranged to be located in the mill To convey grinding media radially to the stirring shaft and thereby the continuously passed through the grinding chamber Good crushed by impact and shear forces or zu disperse.
  • a blockage of the outlet possibly caused Due to the tight tolerances at the good outlet, can be a striking Increase in pressure and the actual grinding and Prevent dispersing process.
  • grinding media will come out of the mill and the grinding agent Dispersion process increasingly deteriorates. moreover In this case, the millbase is contaminated with grinding media.
  • the invention is based on the object, a horizontal axis Agitator ball mill with a novel Separating member to create, not the aforementioned disadvantages and with which a good gently and evenly can be ground with KleinstmahlMechn, the one Have diameter D ⁇ 0.1 mm, without this the grinding chamber leave.
  • FIG. 1 shows a longitudinal section through a part of a horizontal grinding chamber with a separating element of the inventive type
  • FIG. 2 a shows a cross section through the separating element shown in FIG. 1
  • FIG. 2b shows a section along the line IIb of FIG. 2a
  • 3 shows a longitudinal section through a second embodiment of the invention
  • Figure 4 is a plan view of an alternative embodiment of a separating member of the inventive type.
  • the only partially shown in Figure 1 and as a whole designated 50 grinding chamber of a stirred ball mill has a housing 40 with a horizontal axis 60.
  • the Housing 40 has an elongated, substantially cylindrical Longitudinal wall 30 and two at both ends of the longitudinal wall 30 arranged end walls 35 and 36, of which the End wall 36 serving for feeding the ground material Good inlet 37 and the end wall 35 a for discharging the good serving outlet 38 has.
  • a stirrer 1 is arranged, the several, for example two, distributed along the axis 60, Paddle wheel-like impellers 2 has.
  • the axis 60th Coaxial shaft 4 of the agitator 1 is with her the end wall 36 piercing end to one in the drawing not shown drive device connected.
  • separating member 80 In the end wall 35 of the grinding chamber 50 is located a coaxial with the axis 60 arranged separating member 80, which with an external drive 18 is connected. This external Drive 18 displaces the separating member 80 in one of the agitator. 1 independent rotary motion.
  • the regrind outlet 38 leads coaxial with the axis 60 from the separator 80 for rotary feedthrough 17th
  • a seal 45 is provided in the end wall 35, which ensures that no regrind with grinding media the annular gap between separating device 80 and End wall 35 penetrates through to the outside. This seal 45 complies with the requirements for grinding media size ⁇ 0.1mm.
  • the two disks 5 arranged parallel to one another and 7 of the separating member 80 are at a predetermined distance from each other. This is done by several, around the disk center symmetrically distributed, from the disk edge inwards leading, in plan view arcuate conveyor or Wing elements 12 determined.
  • the circular disc 7 sits on the wing elements 12 and is about this with the disc. 5 detachably or permanently connected.
  • a circular cavity 8 between the discs. 5 and Figure 7 may further include a ring cage 10 with one at its end Be located outer surface mesh screen ring 6 inserted.
  • the Ring cage 10 is preferably with O-rings 11th pressed and sealed and can be either with or without Screen plate ring 6 to be mounted. The choice of the use of the Siebblechringes 6 can on the respective Product properties are adjusted.
  • This can be for example primarily products from nanotechnology, but also um Dye suspension, enamel paints, printing inks, Agrochemicals, filler suspension, video tape Coating, cosmetics, food, pharmaceutical or Act microorganisms.
  • the use of Smaller grinding media D ⁇ 0.1 mm is mainly used to Break up agglomerates and aggregates without the Primary particles are destroyed.
  • rotating separator 80 is now formed and measure that from the grinding media and the ground and / or dispersed Good formed mixture in the interspace between the two disks 5 and 7 flows, whereupon due to the centrifugal force and the different specific Density the grinding media serving for grinding the conveying elements 12 separated from the material to be ground and back into the Interior 3 of the grinding chamber 50 are conveyed.
  • the regrind itself passes through the circular cavity 8 of the Separator 80 through the Gutauslauf 38 where it Grinding chamber 50 leaves. By the rotation of the separating member 80th the product must pass through this separator overcome relative to the centrifugal force a relative pressure.
  • the peripheral speed of the separating member 80th and the radial flow velocity in the Flow channels are the determining Operating variables, the peripheral speed of the separating member 80th and the radial flow velocity in the Flow channels.
  • the peripheral speed is determined by the Speed determined.
  • the radial flow velocity results from the free cross section and the volume flow of the product through the pump.
  • the grinding chamber 51 shown in FIG. 3 corresponds essentially the grinding chamber according to FIG. 1. That is,
  • the separating element designated here by 82 is located opposite the agitator 22 on a separate drive shaft and it carries the regrind outlet 39 coaxial with the axis 61 of Separator 82 for rotary feedthrough 17.
  • the drive 28 is in arranged in this case parallel to the axis 61 and offset the the separating member 83 bearing shaft via a sub / translation in a direction independent of the agitator 22 rotational movement.
  • a sieve scraper 65 which serves, if necessary, stuck on the sieve 6 Strip off grinding media, so that no adverse Pressure increase takes place and all grinding media through the Rotational movement of the separating member 82 of the grinding chamber returned can be.
  • FIG. 4 in the form of a paddle wheel-like Separator 85 differs from the above described separating members 80 and 82 in that between the arcuate wing elements 12 additionally straight or slightly curved conveying elements 86 are provided, the extend inwards from the edge of the disc. This forms inside a secondary flow.
  • the separating members 80 and 82 optionally provided with or without straight conveying elements 86 be the conveying elements 12 and 86 either to the Slices 5 or 7 may be attached and it may be the parting organs optionally equipped with or without screen plate ring 6 his.
  • stirring elements described above numerically arbitrary with each other and / or with others Known stirrers are combined and it can the grinding chamber additionally with pressure relief valves or the like be designed to withstand any pressure fluctuations, especially to compensate for pressure increases.
  • longitudinal wall of the grinding chamber in addition of a cylindrical Sheath be wrapped, which together with her in the Cross-section circular, space bounded in the to Cooling or heating of the existing in the interior of a good Cooling or heating fluid can be introduced.
