Further details, meriaaale and "advantages of the invention." result from the following description of an exemplary embodiment with reference to the drawing, in particular in Connection with the additional claims. Show it:

1 shows a vertical cross section through a vibration mixer according to the invention and

FIG. 2 is a plan view of the machine according to FIG. 1, with the top cover removed.

The device has a base frame 5 of essentially cylindrical shape, which has a radially outwardly directed flange 6 at its upper end which a number of vertical coil springs 7 circular is arranged. The upper ends of the springs 7 are connected to a horizontal ring plate 8, on which one middle cylindrical sleeve 9 is attached. On upper and lower bearing brackets or bearing rings Io and 11, which are in Inside the sleeve 9 are mounted, an electric motor 12 is supported with a .Welle 13, which is vertically aligned with the Central axis of the machine is arranged. The shaft 13 carries upper and lower eccentric weights 14 and 15 which are independently adjustable in angle so that they are in their The equilibrium position can be changed in such a way that the resulting imbalance causes a vibration on the ring plate 8 and its structure is achieved or changed. The rotation of the masses resulting in an imbalance in the form of the eccentric weights produces a rotating vibration with upward and downward motion components, the vibration of high Frequency and low amplitude.

A treatment chamber ΐβ is mounted on the ring plate 8 and has an upper section ΙβΑ and a lower one Section Ιβ3 on. These sections are detachable from one another fixed by bolts 17, which by flanges 18a and IBB on the corresponding parts of the treatment chamber to grab. Similarly, a cover plate I9 is with screwed to the upper section ΙβΑ and is the lower Section ΐβΒ screwed to the flange-shaped ring plate 8.

Each section of the treatment chamber has a spiral shape Treatment path, which is limited by a baffle 2o in the best shown in Fig. 2 Vieise. Everyone Section has a conical bottom which is raised towards the central area and radially outwards downwards falls off. With this configuration, one to be mixed is introduced into the center of each of the sections of the treatment chamber Charge of materials is forced into a movement path along the spiral treatment path and thereby the Exposed to movement from the vibration of the machine. Each section of the treatment chamber is peripheral with one Provided outlet opening, the outlet of the upper section ΙβΑ an opening 21 (see. Fig. 2) in the bottom of the section has, from which the material on a conical Satnmeltisch 22 with a central opening 2j5 arrives, polygamy that Feeds material to the center of the lower portion of the treatment chamber. The peripheral outlet of the lower section The treatment chamber has a discharge chute through which the mixed material is removed from the machine is carried out.

The materials to be mixed are in the central area of the upper section of the treatment chamber by means of, for example abandoned funnel-shaped inlet 25, which is mounted on the cover plate I9.

Due to the spiral-shaped design of the upper and lower sections of the treatment chamber together with the vibratory movement by the motor and the eccentric weights and the resilient mounting of the treatment chamber on the fixed base frame of the machine, the material charge to be mixed in each of the sections of the treatment chamber moves in a circle along the spiral paths and is also subject to orbital or circular movements in vertical planes which are essentially at right angles to the direction of movement around the chamber circumference. Through these superimposed .Bewegungen a particularly intimate mixing of the materials is achieved, with consideration of the long treatment path, continuous mixing can be achieved by continuously applying the materials to be mixed at the inlet 25 of the upper section of the treatment chamber and the mixed material continuously the discharge chute 2h of the lower section is discharged.

The frequency and the amplitude of the vibratory movement can vary according to the requirements of the individual case be chosen, but frequencies in the order of magnitude from 9 ° o to ^ jooo rpm and amplitudes of about 0.4 mm up to 9i5 mm (1/64 to 5/8 in.) for most mixing operations are suitable. Different frequencies and / or amplitudes may be required, xsrenn the machine for grinding, Polishing, deburring or other surface finishing is used.

The type of vlbration can be changed to make an adjustment to achieve different materials, including the relative angular positions of the upper and lower eccentric weights 14 and 15 can be set, the speed of rotation of the

Motor or the vertical position of the motor relative to the treatment chamber can be changed. At the exemplary In the illustrated embodiment, the motor is fixedly mounted on the treatment chamber, but can easily a vertical adjustment movement of the motor in the interior of the sleeve 9 can also be made possible, if this is necessary.

Many other modifications and variations of the invention are possible without departing from the scope of the invention. For example, only one spiral treatment chamber can be provided or, conversely, more than two such chambers can be provided if necessary. The sole of the spiral treatment track can instead of the illustrated curved or circular arc shape can also be flat. Since the treatment chamber by means of an upper cover plate is completed, the temperature can be adjusted to different requirements, the pressure or moisture content of the air in the chamber being controlled. In addition, the example explained Use of an electric motor with eccentric weights not a mandatory requirement for the vibration to be generated, rather, the required vibratory movements can also be achieved in other ways, for example by means of electromagnetic or piezoelectric vibrators or by means of air or hydraulic fluid driven Motors with appropriate weights. The angular positions of the weights can be adjusted remotely during operation in order to be able to change or adapt the type of vibration at different treatment stages of the procedure. Instead of helical springs, the treatment chamber can also be resiliently supported by air springs or in some other way be"
