Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides for the crushing (op. ), relating to equipment for grinding and/or mixing. The device has a rotatably supported and driven shaft and at least one knife-like tool, said knife-like means being moved relative to the device.

A number of variants of this type of device are known and are called cutter heads (auttor-M&+1).

Such devices are designed to prevent caking and agglomeration in the mixed materials and to prevent streaks or layers of liquid and paste components from forming with the mixed materials. ...) mounted on the inner wall of the cylindrical vessel of the mixer between the mixing means which rotate within the mixer to achieve mixing. When processing certain extremely fine ingredients, and also when adding liquid and flexibly deformable additives (such as plastic additives, lecithin, molasses, etc.) to the mixed materials, leak-free mixing is very important. It is known to be ineffective or not possible at all. Furthermore, the known cutter heads are not able to provide substantial comminution.

Furthermore, instead of a cutter head, a disc-type abrasive mill (
It is also known to use the lisk attrltion milmg). The mill consists of two disks, each having a number of vertically projecting bins, rotated relative to each other. However, those disk-type attrition mills are
Due to the closed-cage design of the parts related to r), it can only be used for crushing and grinding, and only under certain conditions. This mill is suitable for processing solid mixtures with high fluidity. Or, especially good results can be obtained in the case of liquids.

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus capable of mixing very fine components, liquids, and plastic additives in a bulk material in a 1J-tally and further performing a crushing action. .

The device of the present invention that achieves this object has at least one knife-like tool (a cocooned layer) and is rotatably supported and driven, and has fine particles that are constantly forcibly replenished from the side. Apparatus for crushing, crushing and/or mixing bulk material in the form of solids, granules and/or lumps, wherein each knife-like tool comprises at least one
a plurality of vertically projecting bins arranged along one line, the knife-like tool being associated with a stator, the stator being in physical correspondence with the bins; The device of the present invention is characterized in that it supports bins arranged in a line and protrudes between the bins of a knife-like tool that rotates in combination. Although it has a cutter head type shape, it also has the advantages of a disc lid abrasion mill.

Simply set 1 so that the bins interact with each other at intervals of time.
Being arranged in columns is a huge advantage.

Such an arrangement is particularly useful for plow blades (plows ha).
For forced circulation Ill mixers such as re) mixers, this is extremely advantageous than having the bins dispersed over a large area in constant intertwining. This is because, with the arrangement according to the invention, the new bulk material that is constantly being replenished into the apparatus remains in the apparatus according to the invention only for a relatively short time. Even during such a short residence time in the apparatus, even components that are difficult to handle can be thoroughly mixed in streaks using the apparatus of the present invention.

Furthermore, according to the present invention, forced circulation of the known disc-type attrition mills, where some parts of the bulk material are processed for a very long time and other parts are not properly processed!
- The device of the present invention is particularly effective when processing microcrystals, hard or coarse granular components, and flexibly deformed components. . However, the knife shapes that are combined with each other? - The shape and gap of the bins of the stator and the stator can be selected, for example, so that the fiber agglomerates are broken up without substantially crushing the fibers.

In a preferred embodiment of the invention, both the rotatably supported knife-shaped tool and the associated stator are each designed as horizontally extending flat pars. Two flat pars are located opposite each other, each with intertwining bins.The bins intertwine twice for each revolution of the shirt, and while unentangled they are free of each other. be. In that case, one of the knife-like tools has the effect of cutting the cutter head. In addition, the knife-like tool 141 m with the stator crushes the newly replenished mixture conveyed into the crushing device and has a particularly good crushing and mixing effect. Further, the knife-like tool and the stator may be formed into curved shapes. In either case, the apparatus of the present invention has the advantages of a cutter head and a disk abrasion mill, without the disadvantages of those apparatuses.

Another feature of the invention is that no extreme energy consumption peaks occur during the interlocking of the rotating knife tool bins and the stator bins. That is, the knife-tool bins are arranged offset relative to the stator bins, so that the rotating knife-tool bins pass through the stator bins successively, but not simultaneously. This places the bins of each stator preferably on a radial plane passing through the axis of the shaft, and the bins of the associated knife-like tools preferably lie on a radial plane passing through the axis of the shaft. This is achieved by arranging them along a line. By doing so, it is possible, for example, for the bins located at the leading edge of the knife-like tool to intertwine first, in which case the bins located at the extreme end pass first through the row of bins of the stator; On the other hand, the inner knife-like tool bin continues to pass therethrough. Of course, the opposite arrangement is also possible; the bins can have different cross-sectional shapes, mutual spacing and lengths, but the arrangement of adjacent bins of the stator and the j-shaped tool is as follows: Their mutual spacing is 5
~50 mm, preferably about 20 m1m and a diameter of about 8
III11 is particularly preferred, the gap between the combined bins of the stator and knife-like tool is about 1 to 1.
16++ua is suitable. The IRE stator and knife tool bins are preferably circular in cross-sectional shape, but may have square, triangular, or egg-shaped cross-sectional shapes (with lengths of about 5 to Mowm). preferable.

In another embodiment of the device of the invention, the knife-like tool has bins on its top and bottom surfaces, and a stator with bins is provided to be associated with the top and bottom of the knife-like tool. There is. The bottle of the knife-like tool may be formed by a single bottle passing through the knife-like tool from one side to the other.

It is also possible to arrange a plurality of knife-like tools one on top of the other on the shaft, and to arrange one stator between adjacent knife-like tools.

Each stator consists of flat pars intersecting each other with a 90"% offset. In each case, the essential design for efficient and rapid flow of bulk materials processed in the apparatus of the present invention. is secured.

The device of the invention is designed so that it is always located between the rotating surfaces of the mixing tool, which is arranged at the outer end of the arm, which is arranged radially on the drive shirt of a mixer with a cylindrical container, for example. Next, one embodiment of the apparatus of the present invention will be explained based on the drawings.
