Description

  • Agitator ball mill with a mixing vessel surrounding a stirring shaft, which is provided with a product inlet and a product outlet, wherein the Mahlhilfskörper located within the grinding container are activated by the rotation of the stirring shaft and retained by a separating or classifying device in the grinding chamber.
  • An agitator ball mill of this kind goes out of the FIG. 1 of the DE 44 12 408 A1 out. This agitator ball mill has a double-walled grinding container, which is suitable for cooling. Within the grinding container, the coaxial with the grinding container arranged agitator shaft is connected to a gear and a drive. The grinding container has a Mahlguteinlaß in its lid and centrally in its bottom a Mahlgutauslaß. The product passes through the inlet into the grinding chamber and is processed here by the Mahlhilfskörper located in the grinding chamber. For this purpose, located on the stirrer shaft, provided with holes grinding discs, the Mahlhilfskörper in motion, whereby the energy that acts from the engine to the grinding discs, transfers to the Mahlhilfskörper. The available kinetic energy leads to the dispersion or grinding of the introduced into the grinding container product. Depending on how one operates the agitator ball mill, whether in single or multi-pass process, the product then passes either in its desired final fineness or as an intermediate in the range of Vorklassierstufe which retains the Mahlhilfskörper and possibly also products of appropriate size in the grinding chamber. In addition to the pre-classifier, a separating device may also be provided.
  • From the DD 217 434 B1 is a vertically arranged agitator ball mill known. This agitator ball mill works with a stirring shaft to which a screw-shaped grinding element is attached. In the inlet region of the mill, there is a pre-shredding device connected to the stirrer shaft, which consists of a crushing cone and a crushing ring fastened to the grinding container wall. The material to be ground or the material to be fed passes directly to the top side of the conveyor via a screw conveyor Brechkegels and from there into the crushing gap. After pre-shredding the material falls into the grinding container, where it is processed by the stirring shaft and the Mahlkörpern located in the grinding container. The filling level in the grinding container is monitored by a level measuring device. This is not possible with horizontally arranged mills and mills whose grinding space is fully utilized. In these cases, the material to be ground with the Mahlhilfskörpem in the field of Vorzerkleirierungseinrichtung.
  • The patent application WO 2006/11638 A2 discloses a vertical agitating ball mill which is provided in the inlet area, the material feed, with a pre-shredding device. The pre-shredding is realized via two actively connected rings, wherein one of the rings is at least partially adjustable.
  • The European patent applications EP 0 276 811 A2 and EP 0 276 812 A2 disclose vertical agitator ball mills. These agitator ball mills are provided in the region of the outlet for the ground material with separating devices for separating Mahlhilfskörpem and regrind. For separating elements are arranged on annular rotors, with which the Mahlhilfskörper be transported back by the centrifugal force in the grinding container. There are always several individual elements arranged on a rotatable rotor.
  • The aim of the invention is to combine a grinding and dispersing with a pre-crushing, which is largely protected against the wear that can cause the Mahlgut- / Mahlhilfskörpergemisch.
  • The object is achieved with a stirred ball mill having the features specified in claim 1.
  • Due to the pressure prevailing in the grinding container and the percentage high Mahlhilfskörperfüllung in the grinding container, during the operation of the ball mill, Mahlhilfskörper reach the grinding gap of Vorzerkleinerungseinrichtung and here to wear or other
  • Impairments. Because of this, it is provided according to the invention to protect the grinding gap by a dynamic gap protection.
  • Here, the gap protection is arranged as a rotating part after the pre-shredder.
  • The effect of the gap protection is improved according to the invention in that in this case a ring element is used, which is connected to the rotor of the pre-shredder. In this case, the ring element hurls the Mahlhilfskörper radially in the region of the grinding gap and simultaneously generates a negative pressure zone at the end of the gap transition to the grinding chamber whereby the product easily passes from the grinding zone into the grinding chamber.
  • In an inventive embodiment of the invention, the ring element on the grinding chamber-side end of the grinding gap on a neck, which is designed wedge-shaped.
  • This design has the advantage that between the approach and the ring element, a distance can be maintained, which corresponds to 2 to 10 times the width of the grinding gap. This distance can be adapted in case of complicated construction of the attachment of the ring element, the size of the pre-shredded material or Mahlhilfskörpem.
  • According to a further embodiment of the invention, it may be essential for the function of the pre-shredding device that the dynamic ring element overlaps the grinding gap in a ratio of 2 to 10 times the width of the grinding gap.
  • According to a preferred embodiment, the rotating part of the pre-shredding device is connected to the stirrer shaft.
  • The stationary part of the pre-shredding device communicates with the grinding container. This is particularly advantageous when this area of the grinding container is cooled. Even the cooling of one of the parts of the pre-shredding device keeps the product temperature constant during the pre-shredding.
  • In an advantageous development of the invention, the toothed disks are arranged so that their surfaces directed towards the grinding chamber of the rotating and stationary parts of the pre-shredding device simultaneously form the inlet-side grinding chamber boundary.
  • The gap formed by the stationary and the rotating part of the pre-shredding device is advantageously kept smaller than the diameter of the grinding auxiliary body located in the grinding chamber. In this case, a gap width of 0.2 - 2 mm is selected. The arrangement of additional wings or the like on the grinding chamber facing side of the rotating part, the inflow of pre-shredded product parts can be improved and a Mahlhilfskörperstau avoided or reduced in the shear gap.
  • In a particular embodiment of the invention, either the rotating or the stationary part of the pre-shredding device can be axially adjustable, whereby the gap width can be changed during, before or after the production process. In a purely mechanical embodiment of the invention, both the rotating and the stationary part of the pre-shredding device are axially adjustable via threads on the agitator shaft or on the grinding container. Lock nuts fix the corrected working position.
  • In a development of the aforementioned inventive design, the rotating and / or the stationary part of the pre-shredding device can be corrected by electrical or hydraulic actuators in their position. The initiatable via external command elements piston or electric drives thus allow a direct intervention on the pre-crushing and thus also an intervention on the fineness of the grinding process supplied product.
  • Exemplary embodiments of the pre-shredding device and the agitator ball mill will become apparent from the illustrations described below. Show it:
  • FIG. 1
    a stirred ball mill with pre-crushing according to the invention;
    FIG. 2
    Sectional view of the rotating and stationary part of the pre-shredder FIG. 1 ;
    FIG. 3
    Partial view of the rotating part, which is not part of the invention;
    FIG. 4
    Cutout with crushing gap of execution FIG. 1 ;
    FIG. 5
    Cutout with crushing gap of execution FIG. 1 ,
  • The FIG. 1 shows an agitator ball mill 10 with a grinding container 12 which is surrounded by a cooling jacket 14. In grinding chamber 16 are Mahlhilfskörper 18, which are shown purely for demonstration only in a certain area of the grinding chamber. In the grinding chamber itself is the stirring shaft 20, are placed on the grinding discs 22, with holes 24. The stirring shaft is rotated by a drive, not shown in rotation. To separate the Mahlhilfskörper 18 from the product, which is introduced into the grinding chamber, sitting at the free end of the stirring shaft 20, a preclassifier 26, which consists of a cage-like structure with a plurality of rods 28 and at least one closely spaced to the cage, provided with holes disc 30th can exist. In the embodiment of FIG. 1 In addition, a separator in the form of a sieve 32 downstream of the preclassifier.
  • The product leaves the grinding chamber through the product outlet 34, which is arranged centrally in the grinding container bottom 36. The grinding vessel bottom itself is connected by screws 38 to a grinding vessel flange 40. Through the product inlet 42, the product passes into the inlet chamber 44, to which the seal 46 abuts, which in turn sits on the drive shaft 48. From the inlet chamber, the product passes to the pre-shredding device 50, which is composed of a stationary part 52 and a rotating part 54. The standing part 52 overlaps both the coolant channel 56 and the Mahlbehälterdeckel 58. In a modified embodiment of the invention, the standing and thus the rotating part of the pre-crushing device may be moved towards the grinding chamber, so that the standing ring can be tempered more intensively by the coolant flowing in the coolant channel. The grinding chamber facing surface 60 of the stationary part and the surface 62 of the rotating part form the inlet side grinding chamber boundary. The annular grinding gap has a width of 0.2 - 2 mm.
  • Out FIG. 2 shows the arrangement of a dynamic gap protection 68, which is designed as a ring element 80. The gap protection 68, that is to say the ring element 80, is connected via screws 38 both to the rotating toothed disk 70 and to the rotating part 54 of a hub. The hub has central bores 72, by means of which the attachment to the agitator shaft 20 takes place.
  • FIG. 3 shows a not covered by the invention arrangement of a gap protection 68, which is adjacent only to the grinding gap. Its ring member 80 is made of wear-resistant material such as ceramic, high-alloy steel or the like. The ring member 80 does not overlap the gap in this embodiment. In this case, the proximity of the rotating part 70 to the grinding gap and possibly the generated radial flow is sufficient to keep the grinding gap 64 at its mouth to the grinding chamber 16 free of auxiliary grinding bodies.
  • According to the FIG. 4 and FIG. 5 Embodiments are explained, from which the preferred distances of the projection 74 both radially and axially to the grinding gap 64 and its width a emerge. Thus, the ratio of the width a of the refining gap 64 to the radial overlap c through the shoulder is 1: 3. The axial distance b of the projection 74 to the end of the grinding gap 64 is compared to the width a of the grinding gap 64 in a ratio of 1: 4. This distance ratio allows a resistance-free entry of the pre-shredded product in the grinding chamber 16, since the approach 74 or its, the grinding gap 64 opposite surface does not inhibit the inflow.
  • The projection 74 of the gap protection 68 is in this embodiment as a wedge-shaped or nose-shaped approach. The bevel reduces the wear on the circumference of the ring member 80 and minimizes turbulence.
  • FIGS. 6 and 7 show a variant embodiment in which the gap protection 68 does not work dynamically but statically. For this lies the ring element
