Description

Broyeur de faible encombrement muni d'un rotor incliné par rapport à l'axe de la goulotte d'alimentation Small-sized crusher with a rotor inclined to the axis of the feed chute
La présente invention concerne le domaine du traitement de matériaux de toutes origines, en particulier par déchiquetage au moyen de concasseurs ou de broyeurs à marteaux, ou analogues et a pour objet un broyeur de faible encombrement muni d'un rotor incliné par rapport à l'axe de la goulotte d'alimentation.The present invention relates to the field of the treatment of materials of all origins, in particular by shredding by means of crushers or hammer mills, or the like, and relates to a compact crusher having a rotor inclined with respect to the axis of the feed chute.
La récupération de produits métalliques à partir d'objets hors d'usage, en particulier de véhicules automobiles, au moyen de concasseurs ou de broyeurs, s'effectue généralement par introduction des objets dans un broyeur à marteaux, par l'intermédiaire d'une rampe d'introduction équipée d'un tambour écraseur ; ledit broyeur à marteaux arrache et déchiquette la matière y entrant, par interaction avec une ou plusieurs enclumes, qui éjecte et/ou évacue à travers des parois criblantes les déchets mécaniques obtenus présentant un calibre déterminé. Ces déchets sont ensuite traités en vue d'une élimination des matières impropres à la réutilisation et d'un tri des matières restantes en fonction de leurs caractéristiques métallurgiques.The recovery of metal products from spent objects, especially motor vehicles, by crushers or grinders, is generally carried out by introducing the objects into a hammer mill, via a introduction ramp equipped with a crushing drum; said hammer mill tears and shreds the material entering, by interaction with one or more anvils, ejects and / or discharges through screen walls mechanical waste obtained having a given size. This waste is then treated for disposal of unsuitable materials for reuse and sorting of the remaining materials according to their metallurgical characteristics.
Les broyeurs à marteaux connus à ce jour, dont les marteaux sont généralement montés sur un rotor constitué par un assemblage de disques et sont éclipsables dans le rotor permettent, généralement, un broyage correct des produits suivant une densité prédéterminée. Cependant, ces broyeurs connus sont généralement sous forme d'unité de grandes dimensions, capables de réaliser un rendement journalier très important et ne sont adaptés qu'à des centres de traitement dimensionnés en conséquence. Il en résulte que, pour rentabiliser des installations d'une telle taille, celles-ci doivent nécessairement être en nombre réduit pour couvrir une zone d'approvisionnement importante. Toutefois, si la taille même de telles installations de broyage permet une réduction de leur nombre, elle exige forcément des trajets de transport relativement importants pour amener des produits à broyer à ces installations. Or, un transport à grande échelle de déchets, en vue de leur traitement, entraîne forcément une importante pollution correspondante par les moyens de transport et donc une incidence écologique très défavorable.Hammer mills known to date, whose hammers are generally mounted on a rotor constituted by a disk assembly and are eclipsable in the rotor generally allow a correct grinding of the products to a predetermined density. However, these known mills are generally in the form of large units, capable of achieving a very high daily output and are only suitable for treatment centers dimensioned accordingly. As a result, in order to make facilities of this size profitable, these must necessarily be reduced in number to cover a large supply area. However, even if the size of such grinding plants makes it possible to reduce their number, it necessarily requires relatively large transport paths to bring products to grinding at these facilities. However, large-scale transport of waste for treatment necessarily entails significant pollution by means of transport and therefore a very unfavorable ecological impact.
En outre, les installations de broyage existantes sont extrêmement énergivores, du fait que l'entraînement des rotors de broyage nécessite des moteurs de très forte puissance. En effet, du fait que les rotors sont de grande dimension et s'étendent sur toute la largeur des goulottes d'alimentation, ces rotors ont tendance à tirer sur la matière à broyer de sorte qu'il existe un risque de bourrage entraînant une demande importante de puissance instantanée.In addition, the existing grinding plants are extremely energy-intensive, because the grinding rotor drive requires engines of very high power. Indeed, because the rotors are large and extend over the entire width of the feed troughs, these rotors tend to pull the material to be grinded so that there is a risk of jamming causing a demand important instant power.
Il a également été proposé, dans un souci de réduction de l'encombrement, de réaliser des broyeurs verticaux, dans lesquels le rotor est disposé verticalement dans une enceinte de broyage, qui est alimentée par le haut. Cependant, dans de tels broyeurs, les inconvénients cités plus haut subsistent, du fait que la maîtrise de l'alimentation ne peut pas être assurée, de sorte que les pics de puissance instantanée très élevés subsistent. Par ailleurs, ce type de broyeur ne peut recevoir que des produits de taille réduite, prédécoupés ou prébroyés.It has also been proposed, in order to reduce the bulk, to produce vertical mills, in which the rotor is disposed vertically in a grinding chamber, which is fed from above. However, in such grinders, the disadvantages mentioned above remain, because the control of the power supply can not be ensured, so that very high instantaneous power peaks remain. Moreover, this type of crusher can receive only products of reduced size, pre-cut or pre-milled.
La présente invention a pour but de pallier ces inconvénients en proposant un broyeur de faible encombrement permettant, de traiter ces matériaux directement sur leur lieu de collecte, sans nécessiter de transport supplémentaire et avec une dépense d'énergie réduite.The present invention aims to overcome these disadvantages by providing a compact crusher for processing these materials directly to their place of collection, without requiring additional transportation and with a reduced energy expenditure.
A cet effet, le broyeur de faible encombrement, qui est essentiellement constitué par une goulotte d'alimentation débouchant sur un rotor muni de marteaux de broyage et/ou de découpe coopérant avec une enceinte de broyage munie de parois criblantes, un élément écraseur pouvant être prévu en amont du rotor, au-dessus de la goulotte d'alimentation et à distance de celle-ci, caractérisé en ce que l'axe du rotor est incliné par rapport à l'axe de la goulotte d'alimentation en formant avec cette dernière un angle aigu.For this purpose, the compact crusher, which is essentially constituted by a feed chute opening on a rotor provided with grinding hammers and / or cutting cooperating with a grinding chamber provided with screening walls, a crushing element can be provided upstream of the rotor, above and at a distance from the feed chute, characterized in that the axis of the rotor is inclined with respect to the axis of the feed chute forming with this last an acute angle.
L'invention sera mieux comprise, grâce à la description ci- après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs, et expliqués avec référence aux dessins schématiques annexés, dans lesquels : la figure 1 est une vue en élévation latérale et partiellement en coupe d'un broyeur conforme à l'invention ; la figure 2 est une vue analogue à celle de la figure 1 , d'une variante de réalisation de l'invention, et les figures 3 et 4 sont des vues analogues à celle de la figure 1 d'autres variantes de réalisation de l'invention.The invention will be better understood, thanks to the following description, which refers to preferred embodiments, given by way of non-limiting examples, and explained with reference to the appended diagrammatic drawings, in which: FIG. a side elevational view and partially in section of a grinder according to the invention; FIG. 2 is a view similar to that of FIG. 1, of an alternative embodiment of the invention, and FIGS. 3 and 4 are views similar to that of FIG. 1 of other embodiments of FIG. invention.
La figure 1 des dessins annexés représente, à titre d'exemple, un broyeur de faible encombrement, qui est essentiellement constitué par une goulotte d'alimentation 1 débouchant sur un rotor 2 muni de marteaux de broyage et/ou de découpe 3 coopérant avec une enceinte de broyage 4 munie de parois criblantes 5. Ce broyeur peut éventuellement être muni, en amont du rotor 2, d'un élément écraseur 6 s'étendant au-dessus de la goulotte d'alimentation 1 et à distance de celle-ci.FIG. 1 of the accompanying drawings shows, by way of example, a compact crusher, which consists essentially of a feeding chute 1 opening on a rotor 2 provided with grinding and / or cutting hammers 3 cooperating with a crushing chamber 4 provided with screen walls 5. This mill may optionally be provided, upstream of the rotor 2, with a crushing element 6 extending above the feed chute 1 and at a distance therefrom.
De manière connue, la goulotte 1 est, de préférence, inclinée pour faciliter l'alimentation du rotor 2 par gravité. De même, le rotor 2 peut être entraîné par un ou des moteurs hydrauliques, par un moteur thermique ou par un ou des moteurs électriques. En outre, le rotor 2 peut être équipé par un panachage de marteaux ou d'outils 3 fixes et articulés.In known manner, the chute 1 is preferably inclined to facilitate feeding the rotor 2 by gravity. Similarly, the rotor 2 can be driven by one or more hydraulic motors, by a heat engine or by one or more electric motors. In addition, the rotor 2 can be equipped with a mix of hammers or tools 3 fixed and articulated.
L'élément écraseur 6 peut être monté sur bras articulé 6' ou sur des coulisseaux disposés latéralement à la goulotte d'alimentation 1 et être mû par des vérins hydrauliques. L'écraseur 6 peut être constitué, en lui- même, soit sous forme d'un rouleau animé par un mouvement de rotation réversible qui permet d'écraser mais également de réguler et de doser l'alimentation (figures 1 et 2), soit par un élément en forme de plaque ou de barre actionnée par un piston perpendiculairement au plan de la goulotte d'alimentation 1. Par ailleurs, l'enceinte de broyage 4 est judicieusement pourvue, outre les grilles criblantes 5, d'enclumes, de contre-outils, d'écrans de chocs et de clapets d'éjection non représentés en détail et connus en soi.The crushing element 6 can be mounted on an articulated arm 6 'or on sliders arranged laterally to the feed chute 1 and be moved by hydraulic cylinders. The crusher 6 can be constituted, in itself, or in the form of a roller driven by a reversible rotational movement which can crush but also regulate and dose the feed (Figures 1 and 2), or by a plate-shaped member or bar member actuated by a piston perpendicular to the plane of the feed chute 1. Moreover, the grinding chamber 4 is judiciously provided, in addition to the screening screens 5, anvils, against tools, shock screens and ejection valves not shown in detail and known per se.
Conformément à l'invention et comme le montre plus particulièrement la figure 1 des dessins annexés, l'axe du rotor 2 est incliné par rapport à l'axe de la goulotte d'alimentation 1 en formant avec cette dernière un angle aigu. Ainsi, du fait de l'inclinaison de l'axe du rotor 2 en direction de la goulotte d'alimentation 1 , en formant à sa base un angle aigu, les produits à broyer, amenés sur la goulotte d'alimentation 1 et éventuellement préalablement compactés par l'élément écraseur 6, sont traités progressivement, ce qui permet d'éviter les bourrages et les demandes importantes de puissance instantanée. Bien entendu, dans un mode de réalisation particulier, il peut être envisagé de réaliser un broyeur dans lequel l'axe du rotor 2 est vertical. Dans un tel cas, les produits à traiter seront freinés, dans leur progression en direction du rotor, par des aménagements correspondants.According to the invention and as shown more particularly in Figure 1 of the accompanying drawings, the axis of the rotor 2 is inclined relative to the axis of the feed chute 1 forming with the latter an acute angle. Thus, because of the inclination of the axis of the rotor 2 in the direction of the feed chute 1, forming at its base an acute angle, the products to be ground, fed to the feed chute 1 and possibly beforehand compacted by the crushing element 6, are processed progressively, which avoids jams and significant demands for instantaneous power. Of course, in a particular embodiment, it may be envisaged to produce a mill in which the axis of the rotor 2 is vertical. In such a case, the products to be treated will be slowed, in their progress towards the rotor, by corresponding arrangements.
Selon une caractéristique de l'invention, l'espace biseauté compris entre le rotor incliné 2 et le fond de la goulotte 1 sert de chambre de broyage et de déchiquetage et est garni d'écrans ou d'éléments de choc (non représentés). - A -According to a characteristic of the invention, the bevelled space between the inclined rotor 2 and the bottom of the chute 1 serves as a grinding chamber and shredded and is lined with screens or shock elements (not shown). - AT -
Sur les représentations des figures 1 et 2, l'extrémité inférieure de la goulotte 1 tangente l'extrémité inférieure de l'espace d'action des outils 3 du rotor 2. Cependant, l'extrémité inférieure de la goulotte 1, du côté du rotor, peut également se situer à n'importe quelle hauteur par rapport à la longueur du rotor. Toutefois, de manière préférentielle, la jonction entre le fond de la goulotte et le rotor est effectuée au point le plus bas de ce dernier ou à proximité immédiate, pour assurer au produit à traiter un broyage progressif.In the representations of FIGS. 1 and 2, the lower end of the chute 1 tangents the lower end of the action space of the tools 3 of the rotor 2. However, the lower end of the chute 1, on the side of the rotor, can also be located at any height relative to the length of the rotor. However, preferably, the junction between the bottom of the chute and the rotor is performed at the lowest point of the latter or in the immediate vicinity, to ensure the product to be processed a gradual grinding.
Selon une caractéristique de l'invention, le rotor présente un diamètre utile de travail, c'est-à-dire correspondant au déploiement des outils, qui est au plus égal à la largeur de la goulotte d'alimentation 1.According to one characteristic of the invention, the rotor has a working diameter, that is to say corresponding to the deployment of the tools, which is at most equal to the width of the feed chute 1.
La goulotte d'alimentation 1 peut présenter une forme angulaire, déterminée par un fond plat et des parois latérales verticales, au moins jusqu'à proximité de l'écraseur 6, cette forme angulaire se prolongeant par un cintrage progressif des parties latérales de jonction entre les parois latérales et le fond, ainsi que desdites parois latérales et du fond pour aboutir à une section et une forme sensiblement correspondantes à celles du rotor 2, près de l'extrémité de jonction entre le fond de la goulotte d'alimentation 2 et ledit rotor 1. Il en résulte que la partie de la matière à traiter, qui est compactée par l'écraseur 6 sur la partie amont de la goulotte d'alimentation 1 et se trouvant près des parois latérales, est progressivement rapprochée de l'espace balayé par les outils 3 du rotor 2 et est ainsi également broyée.The feed chute 1 may have an angular shape, determined by a flat bottom and vertical side walls, at least until close to the crusher 6, this angular shape extending by a progressive bending of the lateral parts of the junction between the side walls and the bottom, as well as said side walls and the bottom to end in a section and shape substantially corresponding to those of the rotor 2, near the junction end between the bottom of the feed chute 2 and said rotor 1. As a result, the portion of the material to be treated, which is compacted by the crusher 6 on the upstream portion of the feed chute 1 and located near the side walls, is progressively brought closer to the swept space by the tools 3 of the rotor 2 and is thus also ground.
Bien entendu, il est également possible de réaliser la goulotte d'alimentation 1 entièrement avec une section transversale cintrée, régulière ou irrégulière, c'est-à-dire dont la section se rapproche progressivement de celle correspondant à l'espace balayé par les outils du rotor 2.Of course, it is also possible to make the feed chute 1 entirely with a curved cross section, regular or irregular, that is to say whose section is gradually approaching that corresponding to the space swept by the tools of the rotor 2.
Dans un tel cas, il conviendra, évidemment, d'assurer un compactage des produits à traiter par l'intermédiaire de dispositifs adaptés tels que, par exemple, une ou plusieurs barres longitudinales appliquées sur le produit suivant l'axe longitudinal médian de la goulotte 1.In such a case, it will obviously be necessary to compact the products to be treated by means of suitable devices such as, for example, one or more longitudinal bars applied to the product along the median longitudinal axis of the chute. 1.
Il est également possible, selon un autre mode de réalisation de l'invention non représenté aux dessins annexés, de munir le fond de la goulotte 1 de profils ou de protubérances fixes, amovibles ou escamotables, délimitant par leur génératrice, une section cintrée progressive. Ainsi, il peut être obtenu un effet analogue à celui décrit précédemment. Selon une autre variante de réalisation de l'invention, non représentée aux dessins annexés, la partie inférieure de la goulotte 1 proche du rotor 2 peut être équipée d'un coulisseau déplaçable au moyen d'un vérin et présentant une forme cintrée ou des saillies sur ses bords et à la jonction de ses bords et de la partie de fond. Ainsi, lors d'un déplacement du coulisseau, en direction du rotor 2, les parties de produits n'entrant normalement pas dans le champ d'action des outils 3 du rotor 2, sont déplacées dans ce champ d'action et broyées. Bien entendu, un tel coulisseau doit être affecté d'un mouvement alternatif relativement rapide pour permettre une poursuite du mouvement du produit à traiter en direction du rotor 2.It is also possible, according to another embodiment of the invention not shown in the accompanying drawings, to provide the bottom of the chute 1 of fixed profiles or protuberances, removable or retractable, delimiting by their generatrix, a progressive arched section. Thus, an effect similar to that described above can be obtained. According to another alternative embodiment of the invention, not shown in the accompanying drawings, the lower part of the chute 1 close to the rotor 2 may be equipped with a slide movable by means of a jack and having a curved shape or projections on its edges and at the junction of its edges and the bottom part. Thus, during a displacement of the slide, in the direction of the rotor 2, the parts of products not normally entering the field of action of the tools 3 of the rotor 2, are displaced in this field of action and crushed. Of course, such a slider must be assigned a relatively fast reciprocating movement to allow the movement of the product to be processed in the direction of the rotor 2 to continue.
Selon une autre caractéristique de l'invention, non représentée aux dessins annexés, la goulotte d'alimentation 1 ou le rotor 2 peut être monté sur une articulation de manière à permettre leur basculement mutuel l'un en direction de l'autre, afin de réaliser une variation de l'angle aigu d'inclinaison entre l'axe du rotor 2 et la goulotte d'alimentation 1. Il en résulte la possibilité, lors d'une réduction de l'angle aigu entre la goulotte 1 et l'axe du rotor 2, de réaliser une attaque plus progressive des produits à traiter par les outils du rotor 2, de sorte que la puissance nécessaire au traitement peut encore être réduite.According to another characteristic of the invention, not shown in the accompanying drawings, the feed chute 1 or the rotor 2 can be mounted on a hinge so as to allow their mutual tilting towards one another, in order to make a variation of the acute angle of inclination between the axis of the rotor 2 and the feed chute 1. This results in the possibility, during a reduction of the acute angle between the chute 1 and the axis rotor 2, to achieve a more progressive attack of the products to be treated by the tools of the rotor 2, so that the power required for treatment can be further reduced.
Conformément à une autre caractéristique de l'invention et comme le montrent les figures 3 et 4 des dessins annexés, la goulotte 1 peut également être équipée, à sa partie supérieure, perpendiculairement (figure 3) ou parallèlement (figure 4) à son axe longitudinal, d'au moins deux arbres de déchiquetage 8 en vue de la réduction de la taille des éléments à traiter. Un tel déchiquetage, préalablement au broyage, permet une réduction de la puissance nécessaire pour le broyage, ainsi qu'une amélioration du rendement dudit broyage, une réduction préalable de la taille des déchets étant déjà effectuée. Selon un autre mode réalisation de l'invention, représentée à la figure 2 des dessins annexés, le broyeur peut être muni, en outre, en amont du rotor 2 et, le cas échéant, en amont ou en aval de l'écraseur 6, d'un dispositif 7 de densification et de cisaillage, ou uniquement d'un dispositif de cisaillage, sous forme d'une cisaille guillotine pour la réduction de la longueur des matières à traiter, ce dispositif débouchant dans la goulotte d'alimentation 1 , latéralement, par le dessus ou par son fond à travers une ouverture munie ou non d'un volet de fermeture amovible ou éclipsable (non représenté). Un tel dispositif permet, notamment, d'éviter la pénétration de produits de trop grande longueur dans le champ d'action des outils 3 du rotor 2 et, ainsi, un éventuel bourrage par entraînement de ces produits. Par ailleurs, il est également possible d'équiper la goulotte d'alimentation 1, en amont de l'élément écraseur 6, latéralement, soit d'un côté, soit des deux côtés, de poussoirs débouchant à travers les parois latérales, pour réduire les dimensions des matières à traiter par compactage. Dans un tel cas, il est possible de mettre en œuvre un rotor 2 d'un diamètre réduit par rapport à la largeur de la goulotte d'alimentation 1.According to another characteristic of the invention and as shown in Figures 3 and 4 of the accompanying drawings, the chute 1 may also be equipped, at its upper part, perpendicularly (Figure 3) or parallel (Figure 4) to its longitudinal axis. at least two shredding shafts 8 for the purpose of reducing the size of the elements to be treated. Such shredding, prior to grinding, allows a reduction in the power required for grinding, as well as an improvement in the yield of said grinding, a prior reduction of the size of the waste being already performed. According to another embodiment of the invention, shown in FIG. 2 of the accompanying drawings, the mill may be further provided upstream of the rotor 2 and, if appropriate, upstream or downstream of the crusher 6, of a device 7 for densification and shearing, or only of a shearing device, in the form of a guillotine shear for reducing the length of the materials to be treated, this device opening into the feed chute 1, laterally , from above or from its bottom through an opening provided or not with a removable or retractable closure flap (not shown) Such a device makes it possible, in particular, to avoid the penetration of products of too great length in the field of action of the tools 3 of the rotor 2 and, thus, a possible stuffing by driving of these products. Furthermore, it is also possible to equip the feed chute 1, upstream of the crushing element 6, laterally, either on one side or on both sides, pushers opening through the side walls, to reduce the dimensions of the materials to be treated by compaction. In such a case, it is possible to implement a rotor 2 of reduced diameter with respect to the width of the feed chute 1.
De tels poussoirs peuvent avantageusement se présenter sous forme de coulisseaux actionnés individuellement pas des vérins et affectés d'un mouvement de va-et-vient. Il serait également possible de réaliser les poussoirs sous forme d'éléments de parois latérales articulées. La mise en œuvre de tels poussoirs permet d'assurer un flux continu de matières et le rapprochement de la matière se trouvant dans les parties de coins vers le champ d'action des outils 3 du rotor 2.Such pushers may advantageously be in the form of sliders individually actuated not cylinders and affected by a movement back and forth. It would also be possible to realize the pushers in the form of articulated side wall elements. The implementation of such pushers ensures a continuous flow of materials and the approximation of the material in the corner portions to the field of action of the tools 3 of the rotor 2.
Selon une autre caractéristique de l'invention, la goulotte d'alimentation 1 peut être pourvue, dans sa partie inférieure à proximité immédiate de l'entrée de l'enceinte de broyage 4 et avant les enclumes de cette dernière, de portes d'accès pouvant également servir de clapets d'éjection des produits non broyables et étant garnies ou non intérieurement des éléments de grilles de calibrage.According to another characteristic of the invention, the feed chute 1 may be provided, in its lower part in the immediate vicinity of the inlet of the grinding chamber 4 and before the anvils of the latter, with access doors. can also serve as ejection valves non-grindable products and being internally lined or not calibration grid elements.
L'enceinte de broyage 4 peut, en outre, être équipée, dans sa partie opposée à la goulotte d'alimentation 1 d'un capot, pouvant ou non être garni d'éléments de grilles de calibrage, articulé dans sa partie supérieure et pouvant s'ouvrir à sa partie inférieure par l'intermédiaire de vérins hydrauliques, permettant ainsi d'assurer la maintenance du rotor 2 ou encore de former un clapet d'éjection des éléments non broyables. II est également possible de monter le capot, équipant l'enceinte de broyage 4, dans sa partie opposée à la goulotte d'alimentation 1, sur ladite enceinte de broyage 4, de manière pivotable, indifféremment autour d'un axe de rotation supérieur ou autour d'un axe de rotation inférieur, par prévision de moyens d'articulation et de verrouillage escamotables. En effet, il suffit, dans un tel cas, de prévoir le montage d'un capot de manière pivotante successivement mais non simultanément autour de deux axes, c'est-à-dire de réaliser la jonction de la partie haute et de la partie basse du capot à l'enceinte du broyage, au moyen de broches démontables, le démontage de la broche correspondant à la partie inférieure permettant un basculement du capot vers le haut et, inversement, le démontage de la broche correspondant à la partie supérieure, permettant un basculement du capot vers le bas. Dans le premier cas, le capot sert de clapet d'éjection et, dans l'autre cas, le basculement du capot peut être réalisé pour des besoins de maintenance.The grinding chamber 4 may, in addition, be equipped, in its opposite portion to the feed chute 1 of a hood, which may or may not be lined with elements of sizing grids, hinged in its upper part and being able to open at its lower part by means of hydraulic cylinders, thus ensuring the maintenance of the rotor 2 or to form a non-grinding elements ejection valve. It is also possible to mount the hood, fitted to the grinding chamber 4, in its opposite portion to the feed chute 1, on said grinding chamber 4, in a pivotable manner, indifferently around an upper axis of rotation or around a lower axis of rotation, by providing hinge and locking means retractable. Indeed, it is sufficient, in such a case, to provide for the mounting of a cover pivotally successively but not simultaneously around two axes, that is to say to achieve the junction of the upper part and the part low of hood to the grinding chamber, by means of removable pins, the disassembly of the pin corresponding to the lower part allowing a tilting of the cover upwards and, conversely, the disassembly of the pin corresponding to the upper part, allowing a tilting from the hood down. In the first case, the cover serves as an ejection valve and, in the other case, the cover can be tilted for maintenance purposes.
Selon une autre caractéristique de l'invention, les grilles criblantes 5 de l'enceinte de broyage 4 peuvent, soit être disposées à équidistance des outils 3 du rotor 2 sur toute la hauteur du rotor 2, soit à une distance diminuant progressivement à partir du haut du rotor. Dans ce dernier cas, il est obtenu un espace de broyage et de densification progressif.According to another characteristic of the invention, the screening grids 5 of the grinding chamber 4 may either be arranged equidistant from the tools 3 of the rotor 2 over the entire height of the rotor 2, or at a progressively decreasing distance from the top of the rotor. In the latter case, a grinding and progressive densification space is obtained.
Selon une autre variante de réalisation de l'invention, non représentée aux dessins annexés, l'axe du rotor 2 peut également être disposé obliquement par rapport au plan vertical passant par l'axe du fond de la goulotte et de manière inclinée par rapport à l'axe de la goulotte d'alimentation 1 en formant avec cette dernière un angle aigu. Une telle disposition permet de balayer avec les outils 3 du rotor 2 toute la largeur de la goulotte 1, ce avec un rotor de diamètre inférieur à la largeur de la goulotte 1, le cercle de battement des outils 3 étant utilisé plus judicieusement.According to another embodiment of the invention, not shown in the accompanying drawings, the axis of the rotor 2 can also be arranged obliquely with respect to the vertical plane passing through the axis of the bottom of the chute and inclined with respect to the axis of the feed chute 1 forming with the latter an acute angle. Such an arrangement allows to sweep with the tools 3 of the rotor 2 the entire width of the chute 1, with a rotor diameter less than the width of the chute 1, the beat circle of the tools 3 being used more wisely.
Cette disposition du rotor 2 permet, en outre, une pénétration progressive des matières entre l'espace formé par le rotor 2 et le fond de la goulotte 1 , du fait d'un diamètre de rotor moins important que la largeur de la goulotte.This arrangement of the rotor 2 further allows a gradual penetration of the materials between the space formed by the rotor 2 and the bottom of the chute 1, due to a smaller rotor diameter than the width of the chute.
La disposition des outils de découpe 3 du rotor 2 sur ce dernier peut être effectué avec prévision d'outils 3 mobiles aux deux extrémités du rotor et d'outils fixes dans la partie médiane du rotor, les outils prévus partie en basse étant fixés sur la face extérieure du rotor 2, ou encore, par une disposition en quinconce d'outils fixes et d'outils mobiles. Une prévision d'outils mobiles aux extrémités permet d'optimiser le déchiquetage et l'entraînement des produits vers les enclumes et vers les grilles de calibrage 5, alors que la prévision d'outils analogues à la partie basse permet de racler les produits situés tout en bas du rotor 2.The arrangement of the cutting tools 3 of the rotor 2 on the latter can be carried out with the provision of tools 3 movable at both ends of the rotor and fixed tools in the middle part of the rotor, the tools provided in the lower part being fixed on the outer face of the rotor 2, or alternatively by a staggered arrangement of stationary tools and moving tools. A prediction of mobile tools at the ends makes it possible to optimize the shredding and the drive of the products towards the anvils and towards the calibration grids 5, whereas the prediction of tools similar to the lower part makes it possible to scrape the products located while at the bottom of the rotor 2.
Enfin, conformément à une autre caractéristique de l'invention, la paroi inférieure de l'enceinte de broyage 4, correspondant à l'extrémité inférieure du rotor 2, est avantageusement munie d'ouvertures d'évacuation des produits permettant d'éviter un blocage du rotor ou une usure prématurée par friction.Finally, according to another characteristic of the invention, the lower wall of the grinding chamber 4, corresponding to the end lower rotor 2, is advantageously provided with product discharge openings to prevent rotor jamming or premature wear by friction.
Il est également possible, suivant une autre variante de réalisation de l'invention non représentée aux dessins annexés, de disposer le rotor 2 de telle manière que sa partie inférieure s'étend sous le niveau de la goulotte d'alimentation 1 et de pourvoir ledit rotor 2, sur sa face supérieure, d'outils de coupe et/ou de déchiquetage. Ainsi, la matière compactée arrivant sur la goulotte d'alimentation 1 peut subir, à sa partie supérieure, une action de fraisage par les outils disposés sur la face supérieure du rotor 2 et être entraînés dans l'enceinte de broyage 4, alors que la partie inférieure du rotor 2, située sous le niveau de la goulotte d'alimentation 1, formera, avec l'enceinte de broyage 4, une zone de densification. Grâce à l'invention, il est possible de réaliser un broyeur de faible encombrement permettant une alimentation progressive de l'enceinte de broyage, de sorte que la puissance nécessaire pour le moteur d'entraînement du rotor peut être sensiblement réduite, les à-coups de charge résultant d'un engorgement ou bourrage étant évités. Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention. It is also possible, according to another embodiment of the invention not shown in the accompanying drawings, to arrange the rotor 2 so that its lower part extends below the level of the feed chute 1 and to provide said rotor 2, on its upper face, cutting tools and / or shredding. Thus, the compacted material arriving on the feed chute 1 may undergo, at its upper part, a milling action by the tools disposed on the upper face of the rotor 2 and be driven into the grinding chamber 4, while the lower part of the rotor 2, located below the level of the feed chute 1, will form, with the grinding chamber 4, a densification zone. Thanks to the invention, it is possible to realize a compact crusher for a progressive supply of the grinding chamber, so that the power required for the rotor drive motor can be substantially reduced, the jolts load resulting from clogging or jamming being avoided. Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
