Description

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 tel broyeur ou concasseur à marteaux, ou analogues, pourvu d'un rotor en deux parties.The present invention relates to the field of the treatment of materials of all origins, in particular by shredding using crushers or hammer mills, or the like, and relates to such a hammer crusher or crusher, or the like, provided with a rotor in two parts.

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.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.

Cependant, dans le cas du traitement de déchets de longueur importante, il se présente, avec ces broyeurs, même s'ils sont de très fortes capacité et puissance, un risque de bourrage dû à l'effet d'entraînement qui leur est propre et au fait que lesdits produits sont monolithiques, comme, par exemple, des barres ou des plaques de grandes dimensions.However, in the case of the treatment of long-length waste, it presents itself, with these mills, even if they are very high capacity and power, a risk of jamming due to the drive effect of their own and that said products are monolithic, such as, for example, large bars or plates.

Il est donc nécessaire de réaliser un traitement préalable de tels produits, afin de rendre possible une alimentation plus régulière et sans risque de bourrage des broyeurs. Un tel traitement préalable est généralement effectué dans des installations en aval du site de broyage, les produits étant d'abord prédécoupés et ensuite transportés vers ledit site de broyage.It is therefore necessary to perform a prior treatment of such products, in order to make possible a more regular supply and without risk of jamming mills. Such pre-treatment is generally carried out in plants downstream of the grinding site, the products being first precut and then transported to said grinding site.

Il en résulte la mise en oeuvre de moyens complexes et onéreux, ainsi qu'un encombrement important de l'installation, pouvant être incompatible avec un traitement décentralisé de plus faible volume.This results in the implementation of complex and expensive means, as well as a large size of the installation, which may be incompatible with decentralized processing of smaller volume.

Un broyeur selon le préambule de la revendication 1 est connu du document FR-A-2 242 150 .A grinder according to the preamble of claim 1 is known from the document FR-A-2 242 150 .

La présente invention a pour but de proposer un broyeur selon le préambule de la revendication 1 permettant de réaliser le traitement complet de produits à broyer en une seule opération, avec une machine unique, dans un encombrement réduit et à moindre frais.The present invention aims to provide a grinder according to the preamble of claim 1 for performing the complete treatment of products to grind in a single operation, with a single machine, in a small footprint and cheaply.

Ce but est atteint grâce aux caractéristiques de la partie caractérisante de la revendication 1.This object is achieved thanks to the characteristics of the characterizing part of claim 1.

L'invention sera mieux comprise, grâce à la description ci-après, qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif et expliqué avec référence au dessin schématique annexé, dont la figure unique est une vue en élévation latérale et en coupe d'un broyeur ou concasseur conforme à l'invention.The invention will be better understood, thanks to the following description, which relates to a preferred embodiment, given by way of non-limiting example and explained with reference to the attached schematic drawing, the single figure of which is a view of side elevation and in section of a crusher or crusher according to the invention.

La figure unique du dessin annexé représente un rotor 1 d'un broyeur ou concasseur, qui est muni de marteaux de broyage 2, éclipsables ou fixes et/ou d'outils coupants 3. De manière connue, ce rotor 1 est monté dans une enceinte de broyage pouvant être pourvue de grilles criblantes, d'enclumes, de contre-outils, d'écrans de chocs et de clapets d'éjection. Pour une représentation plus claire de l'invention, seul le rotor 1, qui est monté dans l'enceinte de broyage, est représenté au dessin annexé.The single figure of the accompanying drawing shows a rotor 1 of a crusher or crusher, which is provided with grinding hammers 2, eclipsable or fixed and / or cutting tools 3. In known manner, this rotor 1 is mounted in a chamber grinding system which can be provided with screening grids, anvils, counter-tools, impact shields and ejection valves. For a clearer representation of the invention, only the rotor 1, which is mounted in the grinding chamber, is shown in the accompanying drawing.

Conformément à l'invention, le rotor 1 est constitué en deux parties 4 et 5 entraînées indépendamment l'une de l'autre.According to the invention, the rotor 1 is constituted in two parts 4 and 5 driven independently of one another.

A cet effet, l'une des parties 4 du rotor 1 est équipée d'outils coupants fixes 3, alors que la deuxième partie 5 du rotor 1 est équipée de marteaux 2 fixes ou éclipsables et le rotor 1 présente une inclinaison de son axe longitudinal par rapport à l'horizontale, la première partie 4 du rotor 1, équipée d'outils coupants 3 fixes se présentant à l'extrémité supérieure du rotor 1.For this purpose, one of the parts 4 of the rotor 1 is equipped with fixed cutting tools 3, while the second part 5 of the rotor 1 is equipped with fixed or retractable hammers 2 and the rotor 1 has an inclination of its longitudinal axis relative to the horizontal, the first part 4 of the rotor 1, equipped with fixed cutting tools 3 at the upper end of the rotor 1.

Il est également possible, suivant une variante de réalisation de l'invention, de mettre en oeuvre un rotor vertical à alimentation par le haut ou latéralement, la première partie 4 du rotor 1, équipée d'outils coupants 3 fixes se présentant à l'extrémité supérieure du rotor 1.It is also possible, according to an alternative embodiment of the invention, to implement a vertical rotor fed from above or laterally, the first part 4 of the rotor 1, equipped with fixed cutting tools 3 presenting itself to the upper end of the rotor 1.

Ainsi, la partie supérieure du rotor 1, équipée d'outils coupants 3 fixes, permet de réaliser un grignotage des produits entrant dans le broyeur, les éléments réduits ainsi obtenus étant ensuite traités dans la deuxième partie, inférieure, du broyeur par les marteaux 2 fixes ou éclipsables de la deuxième partie 5 du rotor 1.Thus, the upper part of the rotor 1, equipped with fixed cutting tools 3, makes it possible to nibble the products entering the mill, the reduced elements thus obtained being then processed in the second, lower part of the mill by the hammers 2 fixed or retractable of the second part 5 of the rotor 1.

Le rotor 1 comporte une première partie 4 entraînée par un ou plusieurs premier moteur 4' et formant, du côté opposé à son entraînement par le moteur 4' un palier 41 de logement d'un arbre d'extrémité 51 de la deuxième partie 5 du rotor 1 entraînée par un ou plusieurs deuxième moteur 5', le guidage de l'arbre 51 dans le logement 41 étant assuré par l'intermédiaire de roulements 6 à billes et/ou à rouleaux. Ainsi, chaque partie 4 et 5 du rotor 1 peut être entraînée, du côté opposé à sa liaison par guidage cylindrique à l'autre partie, par son propre moteur 4' ou 5'.The rotor 1 comprises a first part 4 driven by one or more first motor 4 'and forming, on the side opposite to its driving by the motor 4', a bearing 41 for receiving an end shaft 51 of the second part 5 of the rotor 1 driven by one or more second motor 5 ', the guide shaft 51 in the housing 41 being provided by means of ball bearings 6 and / or rollers. Thus, each part 4 and 5 of the rotor 1 can be driven, on the opposite side to its connection by cylindrical guidance to the other part, by its own motor 4 'or 5'.

Conformément à une variante de réalisation de l'invention, non représenté au dessin annexé, l'une des parties 4 ou 5 du rotor 1 peut être entraînée en rotation par l'intermédiaire d'un arbre d'entraînement traversant l'arbre d'entraînement de l'autre partie 5 ou 4 dudit rotor 1. Ainsi, il est possible d'effectuer l'entraînement des deux parties d'un même côté du rotor.According to an alternative embodiment of the invention, not shown in the accompanying drawing, one of the parts 4 or 5 of the rotor 1 can be rotated by means of a drive shaft passing through the shaft of driving the other part 5 or 4 of said rotor 1. Thus, it is possible to drive the two parts of the same side of the rotor.

Selon une autre caractéristique de l'invention, chaque partie de rotor 4' et 5' est entraînée à une vitesse différente de celle de l'autre partie.According to another characteristic of the invention, each rotor part 4 'and 5' is driven at a speed different from that of the other part.

Par ailleurs, l'une des parties 4 du rotor 1 peut avantageusement être équipée d'outils coupants fixes 3, alors que la deuxième partie 5 du rotor 1 peut être équipée de marteaux 2 fixes ou éclipsables.Moreover, one of the parts 4 of the rotor 1 may advantageously be equipped with fixed cutting tools 3, while the second part 5 of the rotor 1 may be equipped with fixed or retractable hammers 2.

Ainsi, la partie 4 du rotor 1 pourra réaliser, par exemple, un travail de pré-déchiquetage, et sera animée d'une vitesse de rotation relativement lente, les outils coupants 3 étant sensibles aux chocs et risquant d'entraîner un blocage de la partie 4 du rotor, ce qui pourrait engendrer des dégâts considérables à une vitesse plus élevée. Par contre, cette première partie de rotor 4 peut assurer une réduction dimensionnelle importante des produits.Thus, the part 4 of the rotor 1 can perform, for example, a pre-shredding work, and will be driven by a relatively slow rotation speed, the cutting tools 3 being sensitive to shocks and may cause a blockage of the part 4 of the rotor, which could cause considerable damage at a higher speed. On the other hand, this first rotor part 4 can ensure a significant dimensional reduction of the products.

La deuxième partie 5 du rotor 1 pourra, dans un tel cas, effectuer le travail d'un rotor de finition en effectuant un broyage des matériaux permettant l'obtention de la réduction dimensionnelle et de la densité souhaitée.The second part 5 of the rotor 1 may, in such a case, perform the work of a finishing rotor by grinding the materials to obtain the dimensional reduction and the desired density.

Cette deuxième partie de rotor 5, qui est avantageusement équipée de marteaux éclipsables tournera préférentiellement à une vitesse plus élevée que la première partie 4.This second rotor part 5, which is advantageously equipped with eclipsable hammers, will preferably rotate at a higher speed than the first part 4.

De préférence, le rotor 1 présentera une inclinaison de son axe longitudinal par rapport à l'horizontale, la première partie 4 du rotor 1, équipée d'outils coupants 3 fixes se présentant à l'extrémité supérieure du rotor 1. Ainsi, les matériaux à broyer pourront être amenés au rotor 1, au niveau de sa première partie 4, pour y être déchiquetés, les éléments déchiquetés étant ensuite acheminés par gravité à l'intérieur de l'enceinte de broyage à la deuxième partie 5 du rotor 1 pour le broyage de finition.Preferably, the rotor 1 will have an inclination of its longitudinal axis relative to the horizontal, the first part 4 of the rotor 1, equipped with fixed cutting tools 3 at the upper end of the rotor 1. Thus, the materials to grind may be brought to the rotor 1, at its first portion 4, to be shredded, the shredded elements then being conveyed by gravity inside the grinding chamber to the second portion 5 of the rotor 1 for the finishing grinding.

Il est également possible de mettre en oeuvre un rotor vertical à alimentation par le haut ou latéralement. Dans un tel cas, on aboutit au même effet que dans le cas d'un rotor à axe longitudinal incliné par rapport à l'horizontale.It is also possible to implement a vertical rotor fed from above or laterally. In such a case, one achieves the same effect as in the case of a rotor with longitudinal axis inclined relative to the horizontal.

L'invention permet de réaliser une machine polyvalente effectuant, en un seul cycle de travail un pré-broyage des matériaux qui peuvent être de grande dimension, suivi d'un broyage de finition pour aboutir à la réduction de taille et à la densité souhaitées. La machine conforme à l'invention permet donc d'effectuer deux opérations distinctes de traitement de matériaux en un seul cycle de travail, alors que dans une installation classique de traitement de matériaux, il est nécessaire de mettre en oeuvre deux machines distinctes. Or, ces machines nécessitent chacune un dispositif d'alimentation propre et, pour garantir la continuité des opérations, un moyen de transfert des produits pré-déchiquetés vers l'installation de finition. Tout ces installations connues nécessitent donc un équipement électrique complexe.The invention makes it possible to produce a multi-purpose machine performing, in a single work cycle, pre-grinding of the materials which may be of large size, followed by finishing grinding to achieve the desired size reduction and density. The machine according to the invention thus makes it possible to perform two separate operations of material processing in a single work cycle, whereas in a conventional material processing installation, it is necessary to implement two separate machines. However, these machines each require a clean feed device and, to ensure continuity of operations, a means of transferring the pre-shredded products to the finishing installation. All these known installations therefore require complex electrical equipment.

Grâce à l'invention, il est possible de réaliser une machine polyvalente unique remplaçant une installation complexe de pré-déchiquetage et de broyage, de sorte qu'un chantier de récupération de ferrailles par broyage de matériaux peut être simplifié de manière importante et donc être réalisé à un coût nettement moins élevé. En outre, une telle installation peut aisément être rendue mobile.Thanks to the invention, it is possible to produce a single multipurpose machine replacing a complex pre-shredding and grinding plant, so that a scrap recovery site by grinding materials can be significantly simplified and thus be achieved at a significantly lower cost. In addition, such an installation can easily be made mobile.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. 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.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawing. 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 the invention.
