Definitions
- the invention relates to a stirred ball mill with a cylindrical grinding container having at least one Mahlguteinlraw and at least one Mahlgutauslenfin, wherein in the Mahlgut actuallyer a connected to a drive agitator shaft is arranged, which transfers a portion of the drive energy to Mahltos stresses that are loosely arranged in the grinding container and a before the Mahlgutauslledge arranged separation device.
- This separating device has a plurality of arcuate conveying or wing elements, which are arranged between two discs on.
- the wing members extend from the outer edge of the discs toward the center thereof, the members terminating in part at different distances from the Mahlgutauslenfin.
- the object of the invention is therefore to improve a separator even for KleinstmahlMech to the effect that even during the start-up and shut-down phase of the agitator ball mill penetration of Mahlos phenomena is prevented in the Mahlgutauslenfin.
- the invention thus provides a stirred ball mill, comprising a cylindrical grinding container having at least one grinding stock inlet and a grinding stock outlet, wherein the grinding container horizontally arranged as shown in the embodiment has a stirring shaft connected to a drive, which transmits a part of the drive energy to the grinding auxiliary body.
- a separator is used which has at least one spiral.
- the separation alignment consists of two spirals.
- a further preferred embodiment provides that the spirals are arranged at a constant distance from each other.
- Another preferred embodiment of the invention is provided to achieve a self-locking of Mahltos emotions each other when the separator is stopped.
- the spiral extends with its radially inner end directly to Mahlgutauslescu.
- the Mahlgutauslenfin may extend on both sides of the longitudinal center of the spiral.
- the width of the spiral (s) is at least one third of its diameter.
- the spiral sits between the agitator shaft surface and the longitudinal axis of the agitator shaft.
- the stirring shaft which has radial openings in this area.
- the slot-shaped openings are inclined counter to the direction of rotation of the stirring shaft.
- the openings of the agitator shaft may be advantageous to make the openings of the agitator shaft tangential or asymmetrical to its longitudinal axis.
- the stirring shaft in the spiral / n with stirring elements consisting of Rhakstäben or cams and which are offset by at least 45 ° to each other.
- the spiral / n contrary to the normal design, in which they consist of sheet metal, consist of individual spaced-apart rods and webs. These rods and webs can, but need not be touching, connected to each other.
- the diameter of the spiral (s) is at least 30% of the grinding chamber diameter.
- the diameter of the spiral (s) is at least 30% of the diameter of the cavity in the agitator shaft.
- the separating device is used with a drive arranged independently of the stirring shaft, it may be advantageous if the spirals are inserted between two full-surface sealing surfaces.
- the side faces located on the spirals end surfaces have openings through which Mahlos stresses can flow back into the grinding chamber.
- the radially outer ends of the spirals are offset by at least 90 ° to each other.
- the agitator ball mill consists of a housing 10 in which a drive 12 is seated in the form of an electric motor.
- the drive is connected by means of a drive belt 14 with a drive shaft 16 in connection.
- This drive shaft passes into the bearing shaft 18, which in turn is connected to the agitator shaft 20.
- the grinding chamber 48 is bounded by the grinding container 26 which surrounds the stirring shaft 20 and the grinding container bottom 28.
- the separating device 30, with which the Mahltosharm 54 are separated from the ground material, sitting within the Stirring shaft 20. For cooling or heating of the grinding container this is double-walled with a coolable or heatable jacket 32 surrounded.
- FIG. 2 shows the arrangement of a spiral 36, within the agitator shaft 20, in the surface of stirring rods 38 are used.
- the millbase flows here centrally from the grinding container 26 via a line 40, which merges into a pipeline 42.
- the FIG. 3 discloses the design of a spiral used, for example, for separating the auxiliary grinding bodies from the material to be ground.
- This spiral 36 extends here over 720 °.
- the grinding material flowing into the spiral passes through the pipeline 40 to the grinding stock outlet.
- the grinding auxiliary bodies are conveyed back into the grinding chamber 48 via passages 46 in the agitating shaft before they enter the worm gear 44.
- FIGS. 4 and 5 Examples of the arrangement of the spiral can be seen, in which the spirals 36 each extend through 360 °.
- the spiral consists of rods, in FIG. 6 from triangular-shaped profiles. Through this in the In the widest sense, rough surfaces of the spirals are said to support the self-locking effect that occurs during stoppage of the stirrer shaft. To increase this self-locking effect, the design of the spiral in FIGS. 4 and 6 be increased by extending the spiral.
- FIG. 5 illustrates the design of the passages 46, the lateral surfaces 50 are directed tangentially to the central axis of the agitator shaft.
- FIG. 7 is a separator 30 can be seen, which has one or more spirals 36. Depending on how long the path of the individual Mahlos stresses in the spiral, the fewer turns must make the separate drive 52 to accomplish a penetration of Mahlos stresses in the Mahlgutauslescu.
- FIGS. 9 and 10 let recognize that the separator operates with a right- and left-handed spiral. It does not matter in the end that the spiral rotates in the opposite direction of rotation as the agitator shaft. The function of the spiral is independent of the direction of rotation of the stirrer shaft.
- FIG. 11 agitator ball mill rotates the separator 30 synchronously with the agitator shaft 20.
- the spiral 36 of the separator abuts with its left side on the agitator shaft and is clamped to the right side by a clamping element 56 with the agitator shaft.
- Centrally in the longitudinal center of the spiral is located in the region of the longitudinal axis of the agitator shaft 20 of the inlet 58 of the Mahlgutauslasses 34th Die
- FIG. 12 illustrates in this case, the length of the spiral 36, which here covers a range of 630 °.
- the design of the separator according to the FIGS. 13, 14 and 15 is especially designed for high-viscosity substances. Since in high-viscosity materials, the forces of resistance between the product and the Mahlos stressesn are very high, you need a longer way to separate the Mahlos redesign, why in FIG. 13 two spirals 36 are provided.
- the outer surfaces of the spirals act as deflectors until the beginning of the other screw. This means that these surfaces 60 produce a pulsating effect in the direction of the grinding chamber and thus already cause a deflection of the auxiliary grinding bodies in the direction of the grinding chamber at the periphery of the separating device.
- the auxiliary grinding bodies are constantly forced to return to the grinding chamber by the frictional forces on the spiral walls and the reverse conveying direction.
- FIG. 14 will be the use of in the FIG. 13 described spirals 36 shown.
- the separator is located here directly on the front side of the overhung agitator shaft 20.
- the product flows centrally via the agitator shaft 20 and bearing shaft 18 from.
- the grinding container bottom 28 has a projection 60.
- the spiral 36 is open in the direction of projection so that Mahlospian can flow back into the grinding chamber 48 on a short path.
- the outer region of the spiral 36 is bounded by a ring 62.
- FIGS. 16 and 17 show separation devices with two spirals, each extending over a range of 500 ° and 560 °.
- the two spirals have screw threads with always constant wall distance A.
- the separating device 30 rotates together with the agitator shaft 20, the product outlet being effected by the agitator shaft 20 and the bearing shaft 18.
- the separator is a projection 60 designed, which is used for flow formation.
- the agitator shaft has in this embodiment, no grinding pins 31, but cam 62.
- FIGS. 18, 19, 20 and 21 demonstrate the location and design of separators with spirals whose spacing is as in FIG. 18 constant, in FIG. 19 reducing and in FIG. 20 are executed widening.
- the FIG. 18 corresponds to the here FIG. 16 in which the distance A remains constant over the entire arrangement of the two spirals 36.
- the spirals 36 are arranged so that the distance B is reduced from the grinding chamber to the outlet.
- This variant is used in particular when low-viscosity material is used and thus it must be expected that the agitator ball mill will be put out of operation for a short time. Due to the reducing distance between the two spirals, the self-inhibiting effect between the spiral walls and the auxiliary grinding bodies is enhanced. Due to the arrangement of the two spirals according to FIG. 20 you can achieve a faster flow of the product after separation from the Mahlos stressesn.
- the illustrated geometry of the two spirals 36 shows that the distance C increases in the direction from the grinding chamber to the Mahlgutauslenfin.
- FIG. 23 Another possibility for conveying auxiliary grinding bodies from the area of the separating device laterally out of the spiral passages back into the grinding chamber is in FIG. 23 shown.
- the separating device 30 is seated within a cavity 64 which is open on one side within the agitator shaft.
- the spiral 36 is held by the agitator shaft 20.
- the ring has a slot 68 through which the Mahlos emotions can flow via the cavity 64 back into the grinding chamber.
- the processed ground material leaves the grinding chamber from the central region within the spiral / s 36 via a dip tube 70. As out FIG. 22 shows, this separator has only one spiral 36.
