Definitions
- the invention concerns a method of mixing materials. More specifically, it concerns mixing of materials, such as e.g. granulate (stones, gravel, sand, etc. ) and liquids by means of two or more rotating, substan ⁇ tially functionally uniform sets of stirring means.
- materials such as e.g. granulate (stones, gravel, sand, etc. ) and liquids by means of two or more rotating, substan ⁇ tially functionally uniform sets of stirring means.
- the object of the invention is to provide a method which gives a more uniform mixing effect in the entire mixing container.
- the invention also concerns an apparatus for performing the stated method and of the type defined in the intro- ductory portion of claim 9, and the characteristics of the apparatus of the invention are stated in the characterizing portion of claim 9.
- fig. 1 shows the fundamental structure of the mixer of the invention
- fig. 2 shows a preferred embodiment of the invention.
- Fig. 1 shows how a plurality of rotating stirring means 10, 20 and 30 in a mixing container 1 are mutually secured to a holder 5.
- the rotating stirring means 10, 20 and 30 are constructed uniformly in princi ⁇ . e and comprise e.g. a plurality of fixed blades 11 and 12, 21, 22 and 23 and 31, 32 and 33.
- the stirring means rotate individually with respect to the holder 5.
- the speeds of rotation c l , t 2 and > 3 for the ⁇ tirrjng means 10, 20 and 30 are disuniform so that e.g. ⁇
- e holder 5 may moreover rotate with a speed of rotati n C ⁇ 5 about an axis 6 common to the stirring means. This common rotation may instead be established in that the mixing container 1 rotates with respect tc the stirring means 10, 20 and 30.
- the common speed of rotation t ⁇ 5 will typically be some orders of magni ⁇ tude smaller than ( ⁇ 1, t ⁇ 2 and C ⁇ 3.
- Fig. 2 shows a preferred embodiment of the invention where the function is provided by means of a planet gear.
- a motor wheel M sets a planet wheel carrier PB in rotation with respect to a fixed sun wheel S.
- Stirring means in a mixing container 50 are provided with a planet wheel PI, P2 or P3, said planet wheel being engaged with the first sun wheel S and rotatably jour- nalled in the planet wheel carrier PB.
- the tooth numbers nl, n2 and n3 for the planet wheel PI, P2 and P3 are mutually different, thereby providing asynchronous rotation of the stirring means. Since the position of blades on the stirring means may.
- the position of the axes of rotation of the stirring means can be selected individually, which may be obtained by inserting an idler gear wheel MT between the sun wheel S and the planet wheel P3. This changes the di ⁇ rection of rotation of the stirring means, and if this is not desirably, two idler means are to be used.
- a mixer according to the inve: - tion may also comprise other means for making the mixiri of materials more efficient. This may e.g. be a mixing screew intended for pulverization of the material, said screew rotating with a considerably greater speed of rotation than the stirring means since its function is different.
