- the device comprises a trough-like housing 20 in which two shafts 10 are rotatably mounted about its longitudinal axis in the present embodiment, wherein the two shafts rotate in the opposite direction of rotation and therefore the attached to one shaft blade elements / striking arms 11 are mirror images of those to the other wave.
- a motor drive 22 for example an electric motor, is provided, which can be arranged at the discharge end of the device.
- the trough-like housing 20 is formed as a container and has a volume which receives the material to be treated to be fluidized.
- blade elements / beater arms 11 are arranged in the region of the radially outer ends, which in the side view can recognize and which are shown here only schematically and will be explained in more detail later with reference to Figure 2.
- the two shafts 10 rotate in the opposite direction of rotation.
- the motor drive 22 may also be arranged at the other end of the shafts 10, where the supply of fresh material to be treated takes place.
- the material to be treated is conveyed from left to right, so that the discharge of the granulate takes place via a discharge connection 21 on the right side downwards.
- the supply of new material to be treated takes place on the left side (in FIG. 1) from above via a feed device, which is indicated by the arrow 23.

- a plan view of the hole distribution plate 26 is shown as a detail in Figure 1 a.
- the perforation seen therein represents only one possible variant. Thus, a very wide variety of types of perforation patterns are possible, for example slots, perforations, other geometries or combinations thereof.
- the granulation device according to the invention can have a further feed device 28, by means of which additives can be introduced into the trogloidal housing 20, for example from above, and applied to the material to be treated.
- an additional feeder 29 may be provided for the supply of steam and / or ammonia (water) from above to the treated. It is also possible to provide an additional supply device 30 for the supply of steam and / or ammonia (water) in the lower region of the device, so that it is also possible to supply such substances from below to the material to be treated.

- one or more baffles 32 may be arranged in the trough-like housing 20, which influence the gas flow in the granulator.
- FIG. 3 shows the two counter-rotating shafts 10 seen in the axial direction.
- each shaft 10 radially extending outwardly striking arms 27 may be provided, at the respective radially outer ends then each blade elements 11 are arranged.
- the blade elements 11 can also each form a single component, that is, the impact arm is shaped and mounted on the shaft, that he also serves as a blade element in the context of the present invention and the blade elements are different than shown in Figure 3 directly to attached to the shafts 10.
- a variant with blade elements 11 formed in this way is shown in FIG.
- FIG. 1 shows a perspective view and schematically simplified a shaft 10 of a granulation device according to the invention, wherein the trough-like housing in which this shaft rotates, not shown here.
- the shaft 10 rotates in the arrow direction of the arrow 9 about its axis, which extends centrally in the longitudinal direction of the shaft 10.
- On the shaft 10 a number of impact arms in the form of blade elements 11, 12, 13, 14, 15, 16, 17 are mounted.
- these vane elements have a flat plate-like shape of airfoils, but may be shaped differently, such as curved, propeller-like, variable width, or the like.
- the exact shape of the vane elements is not critical here, and therefore a simplified flat plate-like shape is shown in the example.
- the arrangement of the blade elements on the shaft influences the behavior of the material to be treated, which is conveyed by the shaft 10 with the blade elements in the trough-like housing of the granulator by the rotation of the shaft in the longitudinal direction of the housing, in Figure 2, this conveying direction denoted by the arrow 8 becomes .
- the shaft 10 has a rear end 18 and a front end 19 as viewed in the direction of conveyance. Near the rear end, a first pair of two vane elements 11 are disposed on the shaft extending radially outwardly from the shaft. The two blade elements 11 of this first pair are arranged offset with respect to the circumference of the shaft 10 by 180 ° to each other, so that they are approximately opposite to the circumference of the shaft.
- the blade element 11 lying in the background in the background can therefore not be seen in the illustration of FIG. 2, while the arrangement of the blade element 11 of the first pair lying in the foreground can be clearly seen. It can be seen that this blade element 11 is set to a plane extending transversely through the axis of rotation of the shaft. The blade element is thus not in this imaginary plane that would cut the cylindrical shape of the shaft 10 in the middle and thus passing through the axis of rotation, but it is inclined to this plane in such a way that the blade element 11 in the side view and in the conveying direction 8 of the treated material seen inclined upwards. In addition, the offset by 180 ° and not visible blade element is rotated by 90 ° to the apparent blade element positioned.
- the unillustrated blade element is therefore not in an imaginary plane that would cut the cylindrical shape of the shaft 10 in the middle and thus by the axis of rotation, but it is inclined to this plane in such a way that the not visible blade element 11 in the side view and in Viewing direction 8 of the material to be treated is arranged inclined downwards. This has the consequence that the fluidized material, which moves in the housing of the device in the direction of the arrow 8, undergoes a lower flow resistance during its movement along the blade element 11.
- the vane element pairs 11, 13, 15 and 17 form an imaginary helix.
- the blade element pairs 12, 14, 16 form a second imaginary helix, but the blade element pair 16 is additionally oriented counter to the direction of flow.
- this in turn leads to an increase in the residence time of the material to be treated in the trough-like housing of the granulation device according to the invention.
- this is specifically used to vary the residence time of the material to be treated in the granulator by making individual blade elements 16 at an opposite angle compared to the other blade elements.
- the orientation of the vane elements on the shaft 10 can best be described as follows.
- the upstream end of the shaft 10 in the flow direction of the material to be treated is defined herein as the rear end 18 of the shaft 10.
- This rear end 18 is located in the entry part of the granulator, ie. There, the material to be treated enters the granulator.
- the front downstream end of the shaft 10 is designated 19 and is located in the discharge part of the granulator, i. there the material to be treated leaves the granulator.
- the flow direction of the material to be treated along the shaft is denoted by the reference numeral 8, i. E. the material to be treated flows from the rear end 18 of the shaft 10 to its front end 19.
- the direction of rotation of the shaft 10 is indicated by the arrow 9, i.
- blade elements 11, 12, 13, 14, 15, 17 are in the embodiment to an imaginary plane extending transversely through the axis of rotation of the shaft 10, set such that its upstream end seen in the direction of rotation of the shaft precedes downstream end.
- the end of the vane element that is located downstream (and on the right in the drawing) precedes the upstream end as the shaft 10 rotates. This can be clearly seen in the blade element 16 in the foreground (for example compared to the blade element 14).
- the second blade element of this pair 16 lying behind the shaft for the observer is not recognizable in FIG. However, it is employed in the same way against the flow direction of the material to be treated, so that it comes with rotation of the shaft 10 by 180 ° with the drawn in Figure 2 blade element 16 to cover.
- the blade elements are arranged in mirror image to those according to the illustration of Figure 2, but then the second shaft rotates in the opposite direction of rotation as the first shaft, so that in both waves with respect to the flow direction of the material to be treated and the direction of rotation of the respective shaft is the same positioning of the blade elements as described in the preceding paragraph.
- a plurality of vane elements 16 may be employed in the manner shown for the vane element 16 in Figure 2, but preferably not all, more preferably only a minority of vane elements are employed in this form.
