Definitions
- the invention relates to a conditioning apparatus for processing material to be processed, comprising a stationary housing having a feed opening for feeding material to be processed and a rotor rotatably mounted in the stationary housing about a substantially vertically extending rotor axis, wherein a plurality adjacent the outer periphery of a base member of the rotor is mounted by bearing pins on the base member, on each of which a processing element is mounted, and wherein the radially outer ends of the processing elements with an inner peripheral wall of the stationary housing a
- Rotor Impact Mill RPM is suitable for the comminution of low to medium abrasive substances, in particular minerals, and is used in particular for the production of sands for any purpose, for example for the concrete, asphalt and dry mortar industry, as well as for the milling of fertilizers
- Rotor Impact Mill RPMV for example, in the recycling industry because it can be used to crush and separate material composites, while material entangling singles, as well as metals can be glued and cleaned.
- the treatment device according to the invention is intended for these types of material processing.
- Bearing journals are connected to each other via a connecting disc.
- the connecting disc provided according to the invention, the forces occurring during material conditioning can be better absorbed by the entire rotor, i. the base element, which are distributed to this fixed journal and the processing elements mounted on these. This makes it possible to operate the rotor at a higher speed, which in turn results in an improved treatment result.
- the connecting disc is designed as an annular disc.
- This embodiment has proven to be completely sufficient in experiments.
- the forces occurring in the material processing are introduced from the conditioning elements namely mainly in the circumferential direction of the rotor in the bearing journals, so that a mutual support of the bearing pin in the circumferential direction of the rotor is sufficient to achieve the desired effect.
- the inner peripheral wall of the stationary housing may be protected at least partially, preferably at least at the level of the treatment elements, by wall cladding elements which together with the radially outer ends of the treatment elements form the treatment gap.
- the wall cladding elements are immovably connected, for example screwed, to the inner peripheral wall of the stationary housing. In this way, changes in the width of the processing nip, which are caused by movements of the wall cladding elements relative to the inner peripheral wall of the stationary housing, reduced, if not completely excluded. This also contributes to a homogenization and thus improvement of the treatment result.
- At least one wall cladding element has a plurality of substantially vertically extending ribs over at least part of the vertical extent of the treatment elements, preferably over their entire height extent.
- the treatment elements are U-shaped, the free ends of the U-shape forming the radially outer ends of the respective treatment element, and the treatment elements the central portion of the U-shape are held only by the centrifugal forces occurring in operation from the inside radially on the associated bearing journal, so that they can evade radially inward, if necessary, process forces which act on them from the processing gap ago.
- a wedge-shaped projection is provided on the inside of the U-shape of the treatment element, said wedge-shaped projection being formed in a wedge-shaped recess of the bearing element corresponding to the wedge-shaped projection. engages pin or a bearing pin mounted on the adapter element.
- the interaction of the wedge surfaces of the wedge-shaped projection with the wedge surfaces of the corresponding wedge-shaped recess makes it more difficult to tilt the treatment element about a substantially vertical axis, which approximates the radially outer end of the treatment element to the inner peripheral wall of the stationary housing Remove the other radial outer end of the inner peripheral wall and thus would have a change in the width of the processing gap result. This stabilization of the storage of the treatment element contributes to a homogenization and thus improvement of the treatment result.
- the opening angle of the wedge shape may be between about 120 ° and 140 °, preferably about 130 °.
- the above-mentioned tilting of the treatment element about a substantially vertically extending axis can also be made more difficult by the fact that the inner surfaces of the mutually substantially parallel sections abut also to each other substantially parallel side surfaces of the journal.
- the processing element can hereby be guided in a substantially radial direction over a length of at least 35 mm, preferably at least 50 mm.
- a plurality of adapter elements is provided, which differ from each other in terms of the distance between the wedge tips of the wedge shape of the wedge-shaped recess facing the treatment element and the wedge-shaped projection facing the bearing pin. From this set of adapter elements, it is possible to select the adapter element which is suitable for the particular application case in hand. Furthermore, this can compensate for a wear-related change in the length of the treatment element. In cooperation with the substantially parallel course of the sections of the treatment element which are adjacent to the radially outer ends of the treatment element, the treatment conditions in the treatment gap can also be kept at least approximately constant even when the treatment element is worn. The aforementioned distance may vary, for example, in steps of a few millimeters, for example in 4 mm increments.
- At least one processing element is formed symmetrically to a horizontally extending plane.
- all conditioning elements have this symmetry.
- a preferably conically shaped distribution element is arranged, which deflects substantially vertically fed aufrendes material in a respect to the substantially vertically extending rotor axis substantially radially extending direction ,
- the material to be reprocessed is accelerated outwards by centrifugal forces upon impact with the rotor, captured by the processing elements and thrown against the inner circumferential wall of the stationary housing.
- the material rebounding from the inner circumferential wall of the stationary housing is in turn gripped by the treatment elements, thereby being crushed by renewed impact and thrown back against the inner circumferential wall of the stationary housing.
- This process takes place several times and causes intensive, multiple use of the material to be reprocessed.
- the processed material exits the rotor through an exit gap between the rotor and the inner peripheral wall of the stationary housing below the processing nip.
- the essentially vertically supplied material to be processed is fed to the upper surface of the connection disk or to an element connected to it.
- the material to be treated is distributed evenly on this upper surface as it strikes the upper surface of the connecting disk or the element connected thereto by centrifugal forces and accelerated radially outward. There it passes through an entrance gap between the inner peripheral wall of the stationary housing and the connecting disc or the connected thereto element in the processing gap between the treatment elements and the inner peripheral wall of the stationary Housing. As it passes through the processing nip, the material to be processed is subjected to impact, tensile, compressive, and shear stresses, thereby disintegrating composites, crushing brittle components, and ductile components are deformed, especially sphered. It should be mentioned as a particular advantage that in this second alternative development, the entire height of the processing gap can be used for processing the material to be processed.
- At least one wall cladding element has a first portion, which is designed and intended, during operation of the treatment device substantially over the upper edge of the Extending processing elements, and a second portion which is designed and intended to extend beyond a predetermined height in the operation of the processing device beyond the rotor.
- all wall cladding elements are formed in this way.
- At least one substantially vertically extending rib provided in the first section extends into the second section, and preferably over the entire height of the second section.
- the at least one rib extending into the second section serves as an obstacle, which is intended to be worked-up material, which, when accelerating radially outwards, also has a velocity component in the circumferential direction, decelerate to facilitate its entry into the processing nip.
- At least one substantially vertically extending rib provided in the first section terminate at a position which, during operation of the processing device, is arranged at least at the level of the upper edge of the processing elements but at most at the level of the upper surface of the rotor.
- the upper edge of the at least one rib is formed with a closing surface which extends obliquely away from the wall covering element and from the second section towards the first section.
- This termination surface serves as a reference slope for the material to be processed, which facilitates its passage from the further section into the narrower section.
- the wall cladding element may have four substantially vertically extending ribs, of which the two outer ribs extend only over the height of the first section, while the two inner ribs extend into the second section and preferably over the entire height of the wall cladding element.
