Definitions
- the invention relates to an eccentric vibratory mill according to the preamble of claim 1.
- vibratory mills consist of cylindrical, trough-like or trough-shaped Rubber buffers or springs freely movable Containers either through a center of mass circumferential or by several to the center of mass coordinated pathogens in the form of imbalances almost set in circular oscillating movements will.
- the grinding media in the grinding bowl are knocked by the vibrating grinding bowl issued by pulse propagation into the interior the grinding media filling.
- the crushing occurs through shock and friction events between the grinding media themselves and between the grinding media and the container wall.
- the mill filling leads against the working direction of the Pathogen makes a circular motion, causing the transport of the regrind is guaranteed.
- the invention is based, through constructive measures the energy input in To increase vibratory mills so that the proportion of low-energy zones minimized and so far Conditional upper limit of the grinding container or Grinding tube diameter of 650 mm are exceeded can.
- the reference symbol (3) represents mill filling clockwise rotation (arrow 5). This leads the mill filling an upward movement on the exciter side (Arrow 6) and on the opposite side of the pathogen Side a downward movement (arrow 7) out.
- the circular oscillation (4a) on the excitation side determines the direction of rotation (5) of the mill filling (3)
- the linear vibrations (4c) on the side opposite to the exciter (2) granted an additional acceleration, so that the Circulation speed about 4 times higher lies than with conventional, circular vibrating Vibrating mills.
- the distance from the axis of the grinding bowl parallel axis of the pathogen is supposed to do this be greater than the smallest distance from the center of the grinding container to the inside of the grinding container.
- Fig. 2 shows the movement conditions when the outside of the axis of gravity and the center of mass exciters (2) arranged on one side on the left Clockwise rotation is driven. Under these conditions there is no orbital movement (5) of the mill filling (3) instead, because the upward movement (6) of the mill filling (3) falls within the range of the linear vibration (4c). The In this case, the ground material is only subjected to stress by push. In contrast, conventional, circular vibrating mills are always in circulation Mill filling instead of against the working direction of the pathogen, regardless of whether the pathogen is legal or Left-hand rotation is driven.
- Fig. 3 shows schematically the design of an eccentric vibratory mill with a vibrationally supported Grinding container in the form of a grinding tube (1) of 600 mm Diameter that is unilaterally outside the gravity axis and the center of mass rigid with an unbalance motor is connected as an exciter (2).
- the pathogen mass is balanced by a axially parallel on the opposite side of the Compensating mass (8) arranged in the grinding tube.
- a second unbalance motor (9) directly on Grinding tube (1) is located.
- the vibratory mill can be optionally either by the pathogen (2) or by the Exciter (9) are operated, each of the other unbalance motor (9 or 2) as a compensating mass acts. This allows the mill to operate with different excitation parameters such as speed and Resonant circuit diameter.
- FIG. 5 Another example of the invention is shown in FIG. 5 shown.
- the grinding tube (1) has in this case a diameter of 1000 mm and is with two one above the other, one-sided outside the gravity axis and the center of mass, synchronous unbalance motors as exciters (2a, 2b).
- the compensation of the pathogen mass takes place again by means of a balancing mass (8) corresponding to FIG. 3.
- FIG. 5 The coupling of structural units according to FIG. 5 is shown in Fig. 6.
- Fig. 6 To adapt to different grinding problems are e.g. two Units (A) and (B) put together to form a mill.
- Eccentric vibratory mill is a grinding vessel in shape a grinding tube (1) by means of vibrating elements (14) vibratable on a base frame (15) supported.
- a crossbar (12) On the grinding tube (1) is on the right a crossbar (12) an excitation unit in the form an unbalance motor (2) rigidly attached, the Spring axis of the drive-side vibrating element (14) between the axes of gravity of the grinding container 1 on the one hand and the excitation unit 2 on the other.
- the unbalance motor (2) On the crossbeam (12) is the unbalance motor (2) the equalizing mass (8) also rigidly attached. Inside the grinding tube (1) are grinding media (13) in the usual way; the movements in clockwise rotation are shown. In Fig. 7 are the end wall (17) of the grinding container as well as the regrind inlet (18) and the regrind outlet (19).
- Vibratory mill according to the invention additionally has still a so-called chamber wheel (20) to the Vibratory mill based on the so-called rotating chamber principle to let work.
- the pathogen (2) is on the left; the movement processes are shown with counterclockwise rotation.

Description
In der nicht vorveröffentlichten DE 42 42 654 A1 wird ein Verfahren zur Naßfeinst- und Trockenfeinmahlung unter Einsatz einer Lineartrogschwingmühle beschrieben, wobei diese Schwingmühle aus zwei übereinander befindlichen, auf Schwingelementen gelagerten Mahlbehältern besteht und deren zwei Erregereinheiten gemäß den Figuren 1 und 2 exzentrisch einseitig außerhalb der Schwerkraftachse und des Massenmittelpunktes der beiden Mahlbehälter angeordnet sind. Erregereinheit und Mahlbehälter liegen aber zwischen den antriebsseitigen und den dem Antrieb gegenüberliegenden Federnachsen. Bei einer derartigen Anordnung gemäß den Figuren 1 und 2 wird entweder eine Kreisschwingung (Fig.2) oder eine Linearschwingung (Fig.1) erzeugt.
- Erhöhung des Auflockerungsgrades der Mühlenfüllung, so daß die bisherige maximale Aufgabekörnung mindestens um den Faktor 2 erhöht werden kann.
- Verbesserung der Transportvorgänge durch hohe Umlaufgeschwindigkeiten der Mühlenfüllung und Homogenisierung der Mahlgutverteilung durch Aufhebung von Entmischungen.
- Erhöhung des spezifischen Durchsatzes.
- Verminderung des Energiebedarfs.
- Aufhebung der energetisch bedingten oberen Grenze des Mahlrohrdurchmessers, der bisher bei 650 mm liegt.
- Verringerung der Stillstandzeiten bei Reparaturen durch Wegfall von Übertragungselementen wie Wellen, Kupplungen u.a.
- Ermöglichung der Modulbauweise durch Kopplung von Baueinheiten mit gleichem Mahlrohrdurchmesser zu Mühlen unterschiedlicher Länge für unterschiedliche Zerkleinerungsaufgaben und Verweilzeiten.
