Definitions
- the invention relates to an agitator mill for treatment, in particular grinding and Dispersion of flowable regrind.
- EP 0 111 703 B1 shows a generic agitator mill for the ground material and Grinding balls in a grinding chamber limited in cross section by two conical surfaces a wedge-shaped displacement ring of the rotor are held in circulation.
- the good outlet and the good inlet are relatively close to the mill axis arranged so that the separated by the separating grinding balls by a Return channel can be added to the incoming regrind. Due to the special geometric shape of the grinding gap formed by the rotor and housing this results in high pressures of grinding balls and in particular the start-up of the mill is difficult because the grinding gap there has a geometry that is very long parallel to gravity, resulting in the above-mentioned high pressures of the grinding balls result.
- EP 0 665 059 B1 deals with the problem of high pressures of grinding balls in an agitator mill. From this prior art the problem is also known that an even circulation of grinding balls in the mill by the influence of the Gravity is hindered when the bed of grinding balls is in the bottom Areas of the mill can accumulate. Especially in mills with cylindrical This effect is particularly pronounced in the agitator and vertical axis of rotation. This leads to, that the grinding ball bed densifies when the mill stops and the mill to Restarting requires a significantly higher engine output than for the grinding operation. Such Mills therefore require a motor drive with an output that is significantly higher lies than would actually be needed for the grinding. This makes the mill unnecessarily expensive.
- EP 0 665 is concerned 059 B1 by proposing a grinding chamber geometry that has the shortest possible parallel paths to gravity.
- an agitator in the form of an annular disk to provide an upper and a lower with the adjacent housing walls Grinding chamber forms a radially inward on the inner areas of the lower grinding chamber Deflection zone connects, in which the ground material with the grinding media from the plane of the upper grinding chamber is deflected and by the connection between the deflection zone and a branch duct for the regrind flow to the separation chamber leads to the upper grinding chamber.
- the agitator is designed in the form of an annular disk and forms two annular disk-shaped grinding chambers.
- the grinding balls due to gravity in the Outer circumferential area of the grinding chambers hurled and compacted, causing it to locally excessive pressing of the grinding media can occur.
- the wear on the outer area of the ring-shaped agitator not only due to the excessive pressings, but also because of the high peripheral speeds very high.
- EP 0 370 022 shows an agitator mill in which the ground material and grinding balls in a grinding gap with a cup-shaped cross section, with a cup-shaped one as well Rotor engages in this grinding gap.
- the disadvantage of this embodiment is the unfavorable Geometry of the arrangement, which in particular the deflection of the ground material with the Grinding balls by almost 180 ° on the underside of the grinding container in a very small space requires. This leads to locally increased wear and also to blockages and thus Failure of the agitator mill.
- a grinding chamber geometry is proposed, which is for very small grinding balls and is suitable for high peripheral speeds of the suspension in the grinding zone.
- This Objective is achieved by an agitator mill, the grinding gap of which is essentially two toroidal boundary surfaces is formed.
- the rotor is preferably a body formed with a toroidal outer surface and the housing surrounds the rotor in such a way that a uniformly narrow grinding gap is created.
- the narrow grinding gap is wide between 5 and 15 mm, preferably a width of 8 to 10 mm.
- a space forms as a grinding gap, which is delimited by toroidal surfaces.
- the way The grinding chamber formed is rotationally symmetrical and has circular cross sections.
- the The suspension of regrind and grinding balls in the grinding gap moves along one Flow path, which with respect to the annular cross section in the outer region of the Grinding gap a downward flow component and in the inner area of the Grinding gap has an upward flow component.
- the rotates Suspension in any circular cross section in addition to the rotation of the suspension about an axis of rotation parallel to the rotor.
- the grinding gap geometry according to the invention allows the grinding and dispersion of suspensions with very high viscosities.
- the agitator mill For use in the paint and coatings industry for the production of high quality
- the agitator mill must be designed in such a way that paint systems and pigment dispersions frequently changing product batches can be produced in a simple manner. To do this the agitator mill should be designed so that it can be easily cleaned. Therefore preferably smooth-walled surfaces of the rotor and housing are used.
- the very narrow one Grinding gap favors cleaning by using the smallest amounts of solution or Detergent the agitator mill can be cleaned. Because of the narrow The loss of regrind is also small, since only small amounts remain in the grinding gap Agitator mill remain.
- the toroidal shape of the grinding gap is for easy emptying of the agitator mill advantageous because there are no dead spaces and the agitator mill solely due to the Gravity can be almost completely emptied. This is at one of the lowest Instead of the grinding gap, an opening is provided which can be closed by a drain screw is. With the elimination of the dead spaces, no deposits can form during the Make the agitator mill stand still.
- a Separating device such as: a sieve surface holds the grinding balls back in the grinding gap, where on the other hand, the finished ground material is separated and discharged.
- the Backflow channels in the vicinity of the separating device allow grinding ball circulation underneath Centrifugal influence and thereby prevent blocking of the separating device in particular at high viscosities of the suspensions.
- the separating device is e.g. a sieve that connects to the rotor is connected and thus rotates.
- the backflow channels are formed between two spokes, which form the toroidal Connect the rotor to the drive shaft.
- This connection between rotor and drive shaft preferably takes place in an area that is approximately at an angle of 45 ° in the interior, upper segment of the rotor.
- This arrangement has the advantage that the Spokes at a standstill with the suspension surface aligned horizontally due to the Do not immerse gravity in the grinding ball bed.
- Rotational speed of the rotor depends on the grinding ball bed due to the high Centrifugal forces almost with a vertical suspension surface, so that at at the highest speeds of the rotor, the spokes do not enter the grinding ball bed plunge.
- the grinding ball bed can be freely aligned in any operating state and flows unhindered and without the influence of disruptive components, e.g. the spokes, in Grinding gap.
- Another advantage is the fact that due to the low contact of spokes and Grinding ball fill, the wear on the spokes is reduced.
- the agitator mill is to be kept low overall, particularly in the area of the grinding gap free of any internals, e.g. Grinding pins.
- a wear behavior wear-reducing coating such as a coating Tungsten carbide or other suitable wear protection agents.
- the rotor and / or the housing can be designed to be coolable.
- the rotor or the housing with internal cooling in the form of cavities equipped with a coolant such as e.g. Water.
- Fig. 1 shows a sectional view of an embodiment of the invention Agitator mill, in particular the separating device according to claim 6 and 7, and the Internal cooling of the rotor according to claim 10.
- Fig. 2 shows a cross section through the embodiment of Fig. 1, in particular the Spokes according to claim 3, the flow pattern according to claim 4, and the Housing cooling according to claim 11.
- FIG. 3 shows a perspective view of the sectional view according to FIG. 2, in particular illustrates the backflow of the grinding balls according to claim 5.
- FIG 4 shows a cross section through a further embodiment, in which in particular the Return flow channels are arranged differently.
- the variant of an agitator mill according to the invention shown in FIG. 1 consists of a two-part grinding container with an upper housing half 1 and a lower housing half 2, which enclose the rotor 3 with a toroidal outer surface. Between the housing halves 1 , 2 and the rotor 3 , the grinding gap 4 defined by two spaced-apart toroidal surfaces is formed.
- the rotor 3 is connected to the drive shaft 6 via spokes 5 .
- the drive shaft 6 is rotatably mounted in a housing flange 7 . The drive takes place via a motor (not shown) coupled to the upper stub shaft of the drive shaft 6 .
- the rotor 3 is designed to be coolable and therefore has a cavity 15 which can be charged with a coolant.
- the coolant is supplied to the cavity via a coolant inlet 16 in the hollow drive shaft 6 and via the bores 17 in a number of spokes 5 .
- a further number of bores 18 in the spokes 5 are provided in order to convey the heated coolant out of the cavity 15 of the rotor 3 again and to lead it away from the agitator mill via the coolant outlet 19 in the hollow drive shaft 6 .
- the material to be ground or dispersed is introduced into the grinding container from above via a grinding material inlet 8 in the upper housing half 1 and is fed to the grinding gap 4 along the truncated cone-shaped connecting piece 9 between the drive shaft 6 and the rotor 3, which also forms the spokes 5 .
- a separating chamber 10 in which grinding balls 13 present in the grinding gap 4 are retained with the aid of a co-rotating sieve device 11 which is firmly connected to the rotor 3 .
- the ground material can pass through the screening device 11 and is conveyed out of the agitator mill via an outlet channel 12 in the drive shaft 6.
- the retained grinding balls 13 return to the beginning of the grinding gap 4 via return flow channels 14 between the spokes 5 .
- Fig. 2 the grinding stock and grinding ball circulation is shown in detail.
- Grist and grinding beads are accelerated radially outwards by the pumping action of the spokes 5 at the beginning of the grinding gap, flow through the circular cross section following the grinding gap and arrive at the separating device at the end of the grinding gap coming from below.
- the actual flow path results from the superimposition of the flow component mentioned with a flow component due to the rotational flow perpendicular to the image plane, which is forced on by the rotor.
- An expansion of the grinding gap 4 in the area of the screening device 11 forms a separating chamber 10 in which the grinding balls 13 are retained. From there, the grinding balls 13 return via return flow channels in the area E between the spokes 5 into the upper area A of the grinding gap 4 .
- the housing halves 1, 2 are coolable.
- the coolant is supplied via a first coolant inlet 20 in the upper housing half 1 , flows through the upper housing half 1 in a first outer ring channel 22a to the opposite end 22b and enters a first inner ring channel 24b there via a first housing passage 23 .
- the coolant once again flows through the upper housing half 1 in the first inner annular channel 24 up to the opposite end 24a and exits from the upper housing half 1 there via the first coolant outlet 25 .
- the coolant flow takes place in the lower housing half 2 in an equivalent manner to the upper housing half 1.
- the coolant is supplied there via a second coolant inlet 30 in the lower housing half 2 , flows through the lower housing half 2 in a second inner annular channel 34a to the opposite end 34b and there it enters a second outer ring channel 32b via a second housing passage 33 .
- the coolant again flows through the lower housing half 2, however, in the second outer ring channel 32 up to the opposite end 32a and exits from the lower housing half 2 there via the second coolant outlet 35 .
- This figure also shows a drain screw 40 with an opening at the lowest point of the grinding chamber for the complete emptying of a grinding material suspension located in the grinding gap 4 .
- the divisible housing with the upper housing half 1 and the lower housing half 2 is tightly closed by clamping screws 41 .
- An elastic sealing ring 42 is provided between the housing halves 1 and 2 for sealing.
- FIG. 4 essentially corresponds to the embodiment shown in FIGS. 1 to 3 , but has slight structural differences compared to this.
- the reference numbers therefore also correspond to those of the previously described embodiment.
- the arrangement of the return flow channels 14 is chosen differently. While these return flow channels 14 connect the end of the grinding chamber 4 immediately after the transition of the grinding chamber 4 into the separation chamber 10 with the beginning of the grinding chamber 4 in the embodiment described above, these return flow channels lie in the embodiment according to FIG. 4 in the same plane as the screening device 11 . the ground material with the grinding balls 13 therefore first encounters after entry into the deposition chamber 10 due to the flow dynamics on the screen device 11, wherein the finely ground material to be ground, these screening passage 11 and enters the discharge passage 12 and the balls 13 rejected by the screening device 11 to the outside and the return flow channels 14 are supplied.
- the return flow channels 14 are therefore - based on the direction of flow of the ground material and the grinding balls 13 - arranged downstream of the screening device 11 .
