Definitions
- the invention relates to a stirred mill according to the preamble of claim 1.
- both the inner grinding chamber and the outer grinding chamber are smooth-walled without perforations and are free of stirring tools.
- the gap width, ie the radial extent of the outer grinding chamber is significantly greater than that of the inner grinding chamber. This is intended to achieve that the grinding and dispersion of the flowable, slurried grind takes place predominantly by shear effects in such a way that the local stress intensity of the grind over the entire Mahlweg is substantially constant. Due to the smooth-walled configuration of the cylindrical boundary walls of the outer grinding chamber and the inner grinding chamber, a flow is generated in which the auxiliary grinding bodies are moved in layers relative to one another.
- the shear gradient and thus the local stress intensity is constant in the outer grinding chamber on the one hand and in the inner grinding chamber on the other hand above the respective Mahlraumiere. Since the gap width of the inner grinding chamber is smaller than the gap width of the outer grinding chamber, the shear gradient in the outer grinding chamber and in the inner grinding chamber can be made the same size; it is then constant over virtually the entire grinding space. It has turned out to be problematical that, with a high grinding auxiliary body filling level, it is difficult to start up the agitator mill. Because of the problems with starting up the agitator mill, it is operated with a reduced grinding aid filling, which in turn leads to an unfavorably wide grinding stock particle size distribution.
- the invention has for its object to design a stirred mill of the generic type so that the startup of the stirred mill easier and during operation a narrow grinding material particle size distribution is achieved.
- the agitator mill can be operated with a high Mahltostage filling level, ie the Mahltostage filling need not be reduced. This in turn leads to a particularly intensive grinding while avoiding a grinding stock pass, since Mahlosterrorism be transported back in sufficient amount by the Mahlos stresses-return channels.
- inventively desired effects are still particularly favorably influenced by the development according to claim 2, wherein the development according to claim 3 continues to be supportive.
- the inner stator is provided in the region of the outflow channel according to claim 12 with a wear protection, which is particularly advantageous if the gap width of the outflow channel to the separating device, ie radially inwardly, not enlarged, so if the flow area is reduced with a corresponding acceleration of the Mahlgut Mahlosêt flow.
- the agitator mill shown in Fig. 1 has in the usual way a stand 1, to which a cylindrical grinding container 2 can be attached.
- an electric drive motor 3 is housed, which is provided with a V-belt pulley 4, of which via V-belt 5 with a drive shaft 6 rotatably connected V-belt pulley 7 is rotationally driven.
- the grinding container 2 consists of a cylindrical inner wall 9 surrounding a grinding chamber 8, which is surrounded by a substantially cylindrical outer jacket 10.
- the lower wall of the grinding chamber 8 is formed by an annular bottom plate 12, which is fastened to the grinding container 2 by means of screws 13.
- the grinding container 2 has an upper annular flange 14, by means of which it is attached to the underside of a support housing 15 by means of screws 16 which is mounted on the stator 1 of the agitator mill.
- the grinding chamber 8 is closed by means of a lid 17.
- the support housing 15 has a central bearing and seal housing 18 which is arranged coaxially to the central longitudinal axis 19 of the grinding container 2. This bearing and seal housing 18 is penetrated by the likewise coaxial to the axis 19 extending drive shaft 6, to which a stirrer 20 is mounted. In the grinding chamber 8 adjacent region of the bearing and seal housing 18 opens a regrind supply line 21 a.
- annular bottom plate 12 a projecting into the grinding chamber 8 approximately cup-shaped, cylindrical inner stator 22 is attached, consisting of a grinding chamber 8 bounding, coaxial to the axis 19, cylindrical outer shell 23 and a likewise coaxial to the axis 19, cylindrical inner shell 24 exists. They limit between a cooling space 25.
- the cooling space 25 is connected to a cooling space 26 in the bottom plate 12, the cooling water via a cooling water supply port 27 is supplied, which is discharged via a cooling water discharge port 28.
- the cooling space 11 of the grinding container 2 is supplied with cooling water via a cooling water supply pipe 29, which is discharged via a cooling water discharge pipe 30.
- a Mahlgut Mahltosève-separating device 32 is arranged, which is connected to a regrind discharge line 33. Between the separator 32 and the drain line 33, a grinding stock hopper 34 is provided.
- the drain line 33 is provided in the region of the bottom plate 12 with a mounting bracket 35, which is releasably connected by means of screws 36 with the bottom plate 12 and the fixedly connected to this inner stator 22.
- the separating device 32 is sealed relative to the annular end portion 31 of the inner stator 22 by means of a seal 37 and can be pulled out after loosening the screws 36 together with the drain line 33 and the collecting hopper 34 from the inner stator 22 down.
- the separating device 32 can thus be pulled out of the grinding chamber 8, without the Mahlospian located in this 38 must be removed from the grinding chamber 8, since the filling of the grinding chamber 8 with these Mahlos stressesn 38 with non-driven agitator 20 does not reach to the front part 31.
- the agitator 20 is cup-shaped in its basic structure, ie it has a substantially annular cylindrical rotor 39.
- the rotor 39 has a cylindrical inner wall 41, which has a cylindrical outer wall 40 and a coaxial with it and coaxial with the axis 19.
- the outer wall 40 and the inner wall 41 are smooth-walled and as closed surfaces trained, so have no openings.
- a cooling space 42 is formed between the outer wall 40 and the inner wall 41 of the rotor 39.
- the agitator 20 is provided with a cover-like termination part 43, to whose bottom side facing the rotor 39, a closure plate 44 is attached.
- the termination part 43 and the end plate 44 are attached to the drive shaft 6.
- a Mahlospian-return module 45 is arranged between the rotor 39 and the end plate 44 of the agitator 20, a Mahlospian-return module 45 is arranged.
- the rotor 39, the return module 45 and the end plate 44 are detachably connected together by tie rods 46.
- an outer grinding chamber 8a is formed.
- an inner grinding chamber 8b is limited.
- this inner grinding chamber 8b protrude on the outer surface 23 of the inner stator 22 mounted, designed as a pin-shaped tools 49 surveys in which - as is apparent in particular from Fig. 4 - are arranged helically over the circumference and the length of the outer shell 23.
- adjacent tools 49 in the circumferential direction of the inner stator 22 overlap one another in the direction of the central longitudinal axis 19 arranged so that in one revolution of the rotor 39 whose inner wall 41 is completely swept by the tools 49.
- the grinding chamber 8 is thus divided into a cylindrical outer grinding chamber 8a on the one hand and a cylindrical annular grinding chamber 8b on the other hand, connected by a constantly widening from outside to inside deflection space 50 in the vicinity of the bottom plate 12 are.
- the cylindrical separator 32 consists of a stack of annular disks 51, between each of which a separating gap 52 is left free, the width of which is generally smaller than the diameter of the smallest grinding auxiliary body 38 used; However, the width can also be greater, since the separation of the Mahlos stresses 38 takes place before reaching the separator 32.
- the stack of annular discs 51 is the end side, ie at the end plate 44 facing side, completed by a closure plate 53.
- the separator 32 is disposed within the return module 45.
- the return channels 54 extend in the direction of the axis 19 almost over the full height of the return module 45, wherein its axial height e is greater than the axial height f of the separator 32.
- Die Return channels 54 extend in this embodiment except via the separator 32 in the direction of the axis 19 still obliquely upward from the upper end of the inner grinding chamber 8b and inside to the separator 32 leading, so tapering in the direction of the end plate 44 towards frustoconical Outflow channel 59.
- the return channels 54 are also open to the outflow channel 59, as Fig. 2 reveals.
- the outflow channel 59 is therefore not spatially limited upwards. Rather, it is open in the direction of the central longitudinal axis 19 towards the internal grinding chamber 8b and thus permeable to the exit of the grinding auxiliary bodies 38, while the millbase flows through the outflow channel 59 in the direction of the separating device 32.
- the material to be ground flows through the grinding chamber 8 corresponding to the flow direction arrows 60 coming from the grinding material supply line 21 through a Mahlgut feed chamber 61 between the end portion 43 of the agitator 20 on the one hand and the lid 17 and the adjacent region of the inner wall 9 on the other hand, the grinding material feed Area 57, the outer grinding chamber 8a down, by the steadily widening deflection space 50 radially inwardly and from there through the inner grinding chamber 8b after on the way up to the outflow channel 59 and from there to the separator 32.
- the material to be ground is milled in rotationally driven agitator 20 in cooperation with the auxiliary grinding bodies 38.
- the ground material leaves the interior grinding chamber 8 b through the separating device 32, from where it flows through the grinding stock discharge line 33.
- FIGS. 6 and 7 differs from that of FIGS. 2 to 5 essentially in that between the end plate 44 and the rotor 39 except a Mahltospian feedback module 45 'still a jam device 62 is provided as part of the agitator 20'.
- a jam device 62 is provided as part of the agitator 20'.
- the inner grinding chamber 8b does not open at its upper end directly into the return channels 54 ', but instead feeds the grinding material.
- Mahltosêt mixture is forced by the jam device 62 obliquely upwards and inwards in the direction of the separator 32 '.
- the gap width j of the outflow channel 59 ' is constant.
- the separating device 32 'does not extend over the full area above the end portion 31. Rather, a closed ring portion as wear protection 63 is provided between the end portion 31 and the separator 32', which is formed integrally with the separator 32 '. Before him or on him the outflow channel ends 59 ', so that from the outflow channel 59' exiting and deflected in an axis-parallel motion Mahltosève 38, the separator 32 'do not hit.
- the embodiment according to FIG. 8 differs from that according to FIGS. 6 and 7 only in that the grinding aid return channels 54 "have a minimum required height e" for trouble-free operation at low grinding stock throughputs. Otherwise, the Mahlosterrorism feedback module 45 "includes here to the jam means 62, wherein in this embodiment, as in the two aforementioned embodiments, the return channels 54" are bounded on their upper side by the end plate 44. The axial height k is the same in the return modules 45 'and 45 ".
- FIG. 9 corresponds to that of FIG. 6 with the difference that no wear protection 63 is provided and that on the other hand the outflow channels 59 '' extend towards the grinding aid separator 32, ie the gap width j '' of the outflow channel 59 '' increases inwards to such an extent that the total cross-sectional area of this channel 59 '' In any case, it does not become smaller in the direction of the separating device 32 so that there is no acceleration of the grinding stock auxiliary body flow in the outflow channel 59 '' to the separating device 32. For this reason, the separating device 32 can extend to the front part 31, since the auxiliary grinding bodies 38 do not hit the separator 32.
- FIG. 10 substantially corresponds to that of FIG. 9, wherein the Mahlosève feedback module 45 "" is not brought up to the separator 32.
- the inlet openings 55 “" of the grinding auxiliary body return channels 54 “” thus have a clear radial distance from the separating device 32.
- this annular space 64 a plurality of scrapers 65 are provided, which are attached to the end plate 44 and rotate with the agitator 20 "".
- the exemplary embodiment according to FIGS. 11 to 13 has a grinding aid body return module 45 ""'which bears against an intermediate ring 66 toward the accumulation device 62.
- the module 45 “"' is thus down to the grinding chamber 8, ie to an end face 67, open.
- the axial height e ""' is constant from the respective inlet opening 55 ""' to the outlet opening 56 ""'and is significantly smaller than the height f' of the separating device 32 '.
