Definitions
- the invention relates to a stirred mill according to the preamble of claim 1.
- Such a stirring mill is known from EP 0 751 830 Bl.
- the distance between the last cage-carrying stirring disk and the adjacent stirring disk is significantly smaller than the distance of the other stirring disks from each other.
- the distance is in each case so large that set so-called Zopfströmonne, that is, adjacent to the stirring discs, the material to be ground flows with the Mahlos emotionsn due to the applied by the stirring discs tangential pulses to the outside.
- Zopfströmonne the distance between adjacent stirring discs must be sufficiently large.
- This distance is also defined by a so-called separation angle, which is enclosed by two lines.
- a line extends between a radially inner end of a stirring disc on the stirrer shaft. The other line is parallel to the axis of the stirrer shaft.
- the angle of separation should be between 30 ° and 60 °.
- the distance between the last stirring disk and the adjacent stirring disk is significantly reduced, so that there takes place a pre-classification before the separator.
- the invention has for its object to design a stirred mill of the generic type so that without increasing the length of a more intensive grinding and dispersing process with good separation of the grinding aid and coarse not sufficiently ground Mahlgutp personality done.

- a drive motor 3 is arranged, which drives a stirrer shaft 5 of a stirrer 6 via a belt drive 4.
- the agitator shaft 5 is rotatably supported in the machine stand 1 in bearings 7.
- the agitator shaft 5 is not stored, d. H. she is in the machine stand
- the grinding container 2 is closed relative to the machine stand 1 by means of a cover 8, which is penetrated by the stirring shaft 5, wherein a seal by means of a shaft seal 9 is effected.
- a grinding material feed 11 opens into the grinding chamber 10 enclosed by the grinding container 2. From the regrind feeder
- I 1 opposite end of the grinding container 2 opens from the grinding chamber 10 final floor 12 a Mahlgut- discharge 13 from.
- the stirring discs 14 On the agitator shaft 5 are - as part of the agitator 6 - mounted as agitating 14 stirring tools, the stirring discs 14 have openings 15 in its outer peripheral region. The distances a adjacent stirring discs 14 in the direction of the axis 16 of the stirring shaft 5 are the same. Only the distance of the lid 8 immediately adjacent stirrer disc 14 from the lid 8 is smaller than the distance a. As can be seen in FIG. 2, the last stirring disk 17 of the agitator 6 adjacent to the bottom 12 is fastened to the agitator shaft 5 by means of a fastening screw 18. The axial distance a 'of this stirring disc 17 from the adjacent penultimate stirring disc 14 of the agitator 6 is identical to the aforementioned respective axial distances a adjacent stirring discs 14. The diameter b of all stirring discs 14 and the diameter b' of the stirring disc 17 are identical.
- a cylindrical cage 19 is formed, which may be formed integrally with the last stirring disk 17. He has distributed over its circumference numerous openings 20.
- passages 22 formed in the last stirring disk 17 open adjacent to the stirring shaft 5.
- a sieve device 23 is arranged concentrically to the axis 16 at the bottom 12. It is mounted on the floor 12, in such a way that the sieve means 23 can be pulled out after loosening from the bottom 12 to the outside. So it is non-rotatably connected to the grinding container 2. From the inner space 24 of the strainer 23 opens the Mahlgut- discharge 13.
- the screen device 23 may be formed by arranged on its cylindrical circumference in a known manner at a small distance from each other annular discs. The inside of the stirrer disk 17, the cage 19 and the screen device 23 thus form a separating device 25.
- the screen device 23 has a closed end plate 26 adjacent to the stirrer disk 17.
- the inner space 24 of the sieve device 23 is thus connected to the separation chamber 21 only via the sieve device 23.
- depressions 27 are formed, which have the same cross-section as the openings 15, but do not lead into the separation chamber 21.
- the depressions are located radially outside the passages 22.
- Mahltosenian 28 filled.
- Mahlgut-feed 11 fi fi easily- able ground material is pumped continuously by means of a pump, not shown, through the grinding chamber 10.
- the agitator 6 is driven in rotation by the drive motor 3.
- the ground material flows through the grinding chamber 10 in the direction of the Mahlgut- outlet formed by the Mahlgut- discharge 13.
- This passage it is subjected to strong shearing stresses by the auxiliary grinding bodies 28 and as a result comminution particles are comminuted and, moreover, the material to be ground is homogenized. This process is carried out in such a way that in each case between adjacent stirrer discs 14 and 14 and 17, shown in Figs. 1 and 2 plait flows 29 set.
- the embodiment according to FIG. 3 differs from the previously described embodiment in that the end plate 26 'extends radially beyond the sieve device 23 into the vicinity of the cage 19, so that the gap space 30' extends. comes closer to the cage 19.
- the embodiment according to FIG. 4 differs from that according to FIG. 2 in that the sieve device 23 'has a smaller axial extent than in the previously described embodiments, so that the gap space 30 "has a greater axial width As a result of this, the grinding stock with grinding aid bodies 28 already has a longer time in the centrifugal field formed within the gap space 30 ", so that the grinding stock and auxiliary grinding body 28 already have a pronounced radial velocity.
- the end plate 26 is arranged as in the embodiment of FIG. 4;
- an intermediate wall 31 is mounted on the agitator 6 between the stirring disc 17 'and the end plate 26, which rotates with the agitator 6 and which defines a gap space 30 ", in which the mixture of ground material and grinding auxiliary bodies 28 stronger is accelerated radially outward, as is the case in the previously described embodiments.
- this intermediate wall 31 is fastened to the agitator shaft 5 with the fastening screw 18, in the exemplary embodiment according to FIG. 6 the intermediate wall 31 'is direct by means of wing-like spacers 32 distributed over the circumference at the stirring disc 17 attached.
- the intermediate walls 31 and 31 'each extend radially at least over the end plate 26; it is therefore: c> d, where c is the diameter of the intermediate wall 31 or 31 'and d is the diameter of the end plate 26.
- c> d wherein the corresponding intermediate wall 27 'extends close to the cage 19. Since the intermediate wall 31 or 31 'rotates with the agitating disk 17, 17', a particularly high acceleration of the ground material and the auxiliary grinding body 28 takes place here.
- a so-called separation angle ⁇ or ⁇ is used.
- the separation angle ⁇ or ß is formed between two lines 33 and 34, respectively.
- the line 33 extends from the inner end 35 of a stirring disc 14 on the stirring shaft 5 to the outer edge 36 of an adjacent stirring disc 14.
- the other line 34 is a line parallel to the axis 16.
- the separation angle ⁇ is that between the last stirring disk 17 or 17 'and the next adjacent stirring disk 14.
- the angle of separation should be 30 ° ⁇ ⁇ 60 ° or 30 ° ⁇ ⁇ 60 °. In other words, this also means that the separation angle ⁇ between the last stirrer disk 17 or 17 'and the next adjacent stirrer disk 14 is such that the above-mentioned Set flows 29, even if the distances a and a 'should not be identical.
- the openings 15 in the stirring discs 14 can - as Fig. 7 can be removed - have a circular cross-section.
- the depressions 27 in the stirring disk 17 according to FIG. 8 are of circular design.
- the openings 15 'in the stirrer disks 14 may have approximately the cross section of outwardly widening trapezoids. The same applies to the recesses 27 'in the corresponding stirring disk 17, as shown in FIG. 10 can be removed.
- the passages 22 in the stirrer discs 17, 17 ' as shown only in Fig. 11, be designed to be actively conveying.
- Their walls 37 do not run parallel to the axis 16 in this case, but are opposite to the direction of rotation 38 and in the flow direction 39 - ie in the direction of the end plate 26 or 26 'or to the intermediate wall 31 out - trailing by an angle ⁇ a parallel to the axis 16 employed.
- the ground material and the auxiliary grinding bodies 28 are drawn into the passages 22 particularly intensively and pressed into the gap space 30 by them.
