Definitions
- the present invention relates to a multi-range twin-shaft cutting system for comminuting material, especially in the form of waste products.
- the material to be crushed is conveyed for example by means of intake elements in the separation region of the waves and processed there.
- EP 0 529 221 B1 describes a twin-shaft shredding system with counter-driven crusher rollers.
- the invention provides a multi-section twin-shaft cutting system for crushing material, comprising: two substantially parallel, counter-rotating shafts, each shaft being surrounded by a roller body; a plurality of support elements, wherein each support member is mounted substantially radially around the roller body, wherein preferably each support member has a radially, wavy, rounded or angular or angular, symmetrical or asymmetrically formed circumferential line; a plurality of separating elements, which are in particular disc-like and / or plate-like, which are each mounted substantially tangentially on the peripheral region of the support elements; wherein the support elements are arranged spaced around the roller body so that in each case a separating element can engage on a support element of a shaft between two immediately adjacent support elements of the other shaft; wherein each shaft has in each case between two immediately adjacent support elements of this shaft on the roller body of the shaft counterparts, which are mounted correspondingly to the separating elements of the other shaft, that the separating elements of the other shaft in opposite directions in
- the two oppositely driven shafts are typically arranged in parallel at a distance, so that the separating elements of a shaft can engage between two directly adjacent support elements of the other shaft. This creates a gap between the two shafts, in which the comminution of the material to be shredded happens. It is understood that the respective separating elements of a shaft do not reach the outer surface of the roller body.
- the roll body can also have a different geometry, such as a polygonal geometry, such as hexagonal or octagonal. It is further understood that the counter-intervention also engage at least the externa ßeren areas each of a separating element of a shaft in the space between two immediately adjacent support members of the other shaft.
- the support elements are typically formed like a disk.
- the opposite direction of drive of the two waves defines, for example, a catchment area of the system approximately above an imaginary plane, which is laid by the two longitudinal axes of the waves and a discharge area below this level, these areas being approximately upwards through the Beginning of the counter-intervention, to be bounded below by the end of the counter-action between the two waves.
- the separating elements of a shaft tangentially arranged on the support elements can be effectively supported, in particular in their function, by counterpart separation elements, which are arranged correspondingly arranged on the roller body of the other shaft.
- a separating element can work against a counterpart separating element.
- work is intended to mean that comminuted material, in particular cut between the separator and the corresponding counterpart separating element.
- corresponding arrangement is intended to mean that the arrangement of said elements, i. Separating elements, counter separating element, supporting elements, it allows that in opposite rotation of the waves, these elements come so close that material is crushed between these elements.
- the counterpart separating element can be made in one piece, but it is also possible for the counterpart separating element to be composed of several pieces. It is understood that a plurality of separating elements can typically be mounted symmetrically on the peripheral region of the support elements.
- the typical disk, circumferentially wave-like shape of the support elements promotes better circulation of the material to be shredded and facilitates or optimizes the collection of the material at the same time.
- the support elements may preferably have a wavy or rosette-shaped circumferential or circumferential region. As a result, the circulation and the collection can be further improved enormously. At the same time, this reduces the energy required for shredding.
- the number of maxima of the waveshape of the support elements can be denoted by n, where n is a natural number.
- the separating elements can be attached to all or at least some of these maxima.
- the separating elements are typically symmetrical, but also unsystematic, mounted around the supporting element. This also applies to support elements that, for example, have no waveform on the circumference.
- the symmetry n will typically be the same for all supporting elements, but may also be chosen differently.
- the partition members of one shaft may each have, at least at their leading edges, a cutting portion which is bevelled, for example, relative to the counterpart members of the other shaft.
- the disc-like and / or plate-like and / or knife-like separating elements may have a rectangular, parallelogram-like or quadrangular shape. It is understood that the separating elements are typically fastened to the supporting elements in such a way that that the separating element is fixed approximately at its center to the support element which is perpendicular thereto.
- the front edge region of the separating elements referred to briefly as the leading edge, which points towards the gap when the waves rotate counter to one another, can exert a higher pressure on a smaller area by means of a cutting region, so that the efficiency of the working process, ie the cutting by cutting against the counterpart separating element, is increased can.
- the dividing elements of the shaft may be formed in width so that the width is slightly smaller than the respective distance between the two opposing support elements, so that in opposite engagement of the separating elements of the waves in the opposite support elements, a separating element of a shaft against two immediately adjacent support members of the other wave breaking and / or cutting sideways works.
- the dividing elements of one shaft can be arranged corresponding to the dividing elements of the other shaft such that, when the dividing elements of the shafts engage in opposite directions, a separating element of one shaft fractures against an immediately adjacent separating element of the other shaft.
- the dividing elements are typically fastened to the supporting elements in such a way that the dividing element is fastened approximately at its center to the supporting element which is perpendicular thereto.
- a separator of a shaft is thus tangential, approximately centrally attached to the support member.
- a separator of a shaft for simplicity's sake referred to as the first separator, can engage between two adjacent support members of the other shaft. These adjacent supporting elements of the other shaft in turn carry separating elements which move in the opposite direction to the first separating element.
- material to be shredded can be cut, cracked or broken between the first separating element and an adjacent separating element of the other shaft. This comminution typically takes place in the catchment area.
- the material to be crushed can be broken and / or cut and torn very early.
- the separating elements of one shaft can be arranged corresponding to the separating elements of the other shaft such that, when the separating elements of the shafts engage in opposite directions, a separating element of one shaft works in cutting fashion against a corresponding separating element of the other shaft the leading edge of the separating element of the one shaft working against the edge of the other edge facing away from the edge.
- a partition member of one shaft which is referred to as a first partition member for convenience, can be engaged between two adjacent support members of the other shaft. These adjacent supporting elements of the other shaft in turn carry separating elements which move in the opposite direction to the first separating element.
- the separating elements of the other shaft may be arranged corresponding to the first separating element of a shaft such that the front edge of the first separating element can perform a crushing operation against the edge facing away from the leading edge of the other separating element of the other shaft, ie the rear edge.
- the separating elements of one shaft may be arranged corresponding to the separating elements of the other shaft and the counterpart separating elements of the other shaft, that within a single opposite rotation of both waves in opposite directions of the shafts of the waves first Separating element of a shaft against a directly adjacent pair of support members of the other shaft cutting and / or breaking works, then the separating element of a shaft against the corresponding separating element to this separating elements of the other shaft cutting works and then the separating element of a shaft against the separating element of another shaft which is attached corresponding to this separating element, against which the front edge of the other separating element facing away edge, cutting works.
- the arrangement of the separating elements of a shaft corresponding to the separating elements of the other shaft and corresponding to the counterpart separating elements of the other shaft thus allows four separation processes / comminution processes with respect to the material to be comminuted within a single opposite rotation of the two waves.
- the first separation process consists, for example, in that the material is drawn, broken and torn between a separating element of one shaft, which for reasons of simplicity is referred to as a first separating element, and a separating element of the other shaft, which is referred to as a second separating element for the sake of simplicity.
- the first separation process typically occurs in the catchment area of the two support elements of the other shaft.
- the separating element of one shaft is inserted between the two supporting elements of the other shaft.
- the separating elements only slightly smaller in width than the distance between the support elements of the other shaft, it comes between the separating element and the corrugated side edges of the support element to a second predominantly refractive, but also a cutting and tearing second crushing process.
- This second separation or comminution process typically still takes place in the catchment area of the two support elements.
- the material is comminuted, separated, cut, between the first separating element and a corresponding counterpart separating element of the other shaft.
- This third separation process typically also takes place in a region between the two support elements of the other shaft.
- the material between the first separator of the one shaft and the separator of the other wave again crushed, cut approximately.
- the front edge of the separating element of the one shaft works against the edge facing away from the front edge of the other separating element.

- each separator of one shaft may correspond to two counterparts of two immediately adjacent support members of the other shaft, the two counterparts being spaced axially between the two support members.
- the counterpart dividing members may be provided directly on the support members on the roll body.
- the countertraction elements can be formed virtually directly on the support elements or be suitably fastened or welded to the support elements. It is understood that the radial height of the counterparts is typically less than the radial height of the support members.
- the counterpart dividing elements can be cuboidal or rectangular in shape and, in particular, can be provided perpendicular to the support elements in the axial direction.
- the counterpart dividers may each have, at their leading edges facing the other shaft, a cutting area which is bevelled, for example.
- the counterparts may be formed cuboid or like a block, whereby an anvil-like action against the corresponding separating elements can be achieved.
- the counterpart separating elements in turn may have, at their leading edges facing the other shaft, a cutting area which is bevelled, for example, so that in each case the cutting area of the counterpart separating element and of the corresponding separating element can achieve a cutting action.
- the leading edges of the divider elements may be disposed substantially in the axial direction parallel to the longitudinal axis of the shaft or the leading edges of the divider elements may be inclined at an angle ⁇ to the longitudinal axis of the shaft, where 0 ° ⁇ ⁇ 90 ° °, preferably 0 ° ⁇ ⁇ 45 °.
- the separating elements Due to the slope of the leading edges of the separating elements, the separating elements can be adapted to specific comminution tasks.
- the divisional elements of the other shaft corresponding to the partition members of one shaft may be arranged in accordance with the slope of the corresponding partition members.
- the counterpart dividing elements are typically arranged according to the slope of the separating elements in order to produce the highest possible efficiency. If the slope is 0 °, i. the leading edges of the separating elements are substantially parallel to the longitudinal axis of the shaft in the axial direction, for example, the slope of the separating elements is also 0 °.

- the catch elements can be provided, for example, on every second or third support element. It may be provided on all or at least some of the separating elements for a support element with catch elements, the catch elements. In this case, the catching elements may be present approximately at the position of the separating elements in the middle of the separating elements. It is understood that the catch elements are formed so that they do not touch the surface of the roller body of the other shaft upon rotation of the waves. The catch elements improve the feeding of uncut material into the catchment area of the two shafts.
- the support elements may each have a protective element or other suitable wear protection at their smallest distance to the shaft center point, which point in each case to the other shaft.
- the protective element, wear protection or special wear element on the support elements is typically attached to the mid-point closest to the wavy narrow side of the support elements and serves, for example, to protect this point, since this point is most heavily stressed by the comminution process .
- the two shafts can be driven synchronously or asynchronously, with each of the shafts being interchangeable.
- each of the two shafts can be driven via a transmission hydraulically or mechanically or by a direct drive.
- a gearbox or a direct drive can ensure the corresponding power transmission hydraulically or mechanically.

In the axial direction, the catch elements 13 and 15 are provided only on some of the support elements 9, 1 1 in Figure 1. It is understood, however, that catch elements 13, 15 can be provided both on some and on all support elements 9, 11. Purely by way of example, the catch elements 13, 15 are provided in FIG. 1 only on every third support element 9, 11.

- the counterpart separation elements 21 and 23 can be designed both continuously and also interrupted between two support elements 9, 11.
- a separate separating element 21, 23 can therefore be interrupted within the intermediate space in the axial direction. You can also call such a separating element as two or more parts. It is important, however, that the separate separating element 21, 23, in one-part or multi-part form corresponds in each case to the corresponding separating element 17, 19 of the respective other shaft.
- the dividing elements 17 and 19 may bevelled at their leading edge, ie the edge which, with respect to the direction of rotation, is substantially first in contact with the material to be comminuted, as shown in the following FIGS. 3A-3C. Likewise, the front edge of the respective separating elements 17, 19 have an angle against the longitudinal direction of the shaft 1, 3.
- This angle can be between 0 ° and 90 °, preferably between 0 ° and 45 °.
- the support elements 9 respectively 1 1 of the left and the right shaft 1, 3 are each offset by a few degrees against each other. This arrangement is also clear in the following figures. As a result, the intake and crushing movement of the shaft 1, 3 is further supported.

It is understood that the support member 9 engages directly between the support member 1 1 and immediately behind the support member 1 1 lying further support member of the right shaft.
- the opposite movement of the two shafts 1, 3 causes the material to be shredded between the separating element 19R of the right shaft 3 and the separating element 17L of the left shaft 1 retracted, cracked and / or broken.
- This comminution thus takes place in the sectional view substantially in the axial direction.
- the wave-shaped circumferential line of the support elements 9, 1 1 supports this crushing process.
- the left shaft 1 continues to rotate in the clockwise direction and the right shaft 3 counterclockwise. As a result, the left support member 9 and the right support member 1 1 are also rotated further.
- the area II indicates the right dividing element 19R and the corresponding left dividing separating element 21. These come so close within the revolution that the material to be shredded is separated and / or cut between the separating element 19R of the right shaft 3 and the separating element 21 of the left shaft 1.
- the counterpart separating element 21 is shown as anodic in the form shown here.
- an anvil shape may also be a cutting-like shape be chosen to ensure the separation in a cutting form of the material.
- the correspondence between the separating element 19, 17 and the counterpart separating element 21, 23 is shown here only as an example for a separating element 19R of the right shaft 3 and corresponding counterpart separating element 21 of the left shaft 1.
- FIG. 3C shows within the same revolution corresponding to the arrangement of the separating elements 19R and 17L, a further crushing operation in sequence to the second and connects the third crushing operation.
- the separating element 19R is the same separating element as shown in FIG. 3B.
- the separating element 19R of the support element 11 of the right shaft can here work against the rear side of the separating element of the left shaft 17L, so that the material to be comminuted is again comminuted and / or cut. This repeated crushing happens in the outlet area III of the cutting system.
- a very uniform and almost overgrained final product is produced.
- the cutting system 100 according to FIG. 1, which was explained in more detail with reference to FIGS. 2A, 2B, 2C, 3A, 3B3C, can be provided inside a crusher (not shown here).
- a crusher may have a funnel-like attachment, funnel, into which the material to be shredded is added.
- This funnel-like attachment may typically be provided above the catchment area of the cutting system 100.
- the fangs 13 and 15 act supportive. It is possible to provide push-pull systems which press the material to be comminuted into the hopper and thus into the comminution unit.
- a system may be provided below the cutting system 100 (not shown), a system may be provided to retain the oversized grain contained in the shredded material and to discharge it accordingly and move it away from the cutting system 100 via a conveyor belt for further use, for example.
- the cutting system 100 can be provided in a mobile, semi-mobile or stationary crusher.
