Abstract

The metal grinder is constituted from a casing (1) inside which moves a rotor (2) equipped with hammers (3). The rotor rotates in the direction of the arrow and each hammer passes with a minimum of play next to an anvil (5). The parts wedged between the hammer and the anvil are shredded and projected through the upper outlet grille (6) . The casing has a door (7) with a face drilled with square, rectangular or circular openings, each sized as a function of the grille openings.. The openings are conical with the largest dimension directed towards the inside of the grinder. The lower edge of the door is reinforced by a protuberance forming a supplementary nose.

Description

Les broyeurs de métaux principalement les broyeurs d'automobile sont généralement constitués d'une caisse garnie de revêtement d'usure à l'intérieur de laquelle évolue un rotor à la périphérie duquel sont montées des lignes de marteaux. Le rotor est animé d'un mouvement de rotation, il entraine les marteaux qui frappent et déchirent les objets métalliques, principalement les carrosseries d'automobile. Le produit ainsi déchiqueté est projeté à l'extérieur de la caisse au travers d'une grille. Metal shredders, mainly automobile shredders, generally consist of a body lined with wear coating inside which a rotor moves, on the periphery of which are mounted lines of hammers. The rotor is driven in a rotational movement, it drives the hammers which strike and tear metal objects, mainly automobile bodies. The product thus shredded is projected outside the box through a grid.

Une porte disposée latéralement permet d'évacuer les morceaux trop gros que l'on appelle les imbroyables et qui ne peuvent passer au travers de la grille.A door arranged laterally makes it possible to evacuate the too large pieces which one calls unburnable and which cannot pass through the grid.

Cette porte est manoeuvrable par l'opérateur chargé de la conduite de la machine.This door can be operated by the operator responsible for operating the machine.

Pour obtenir un produit plus finement broyé, que l'on appelle du 332, il est nécessaire de le reconditionner par un second passage à l'intérieur de la machine.To obtain a more finely ground product, called 332, it is necessary to recondition it by a second pass inside the machine.

Cette opération conduit à une saturation de la machine à laquelle l'opérateur remédie en entrouvrant légèrement la porte ce qui conduit à obtenir un produit moins bien calibré, d'une granulométrie supérieure, mais aussi conduit à une usure anormale de la porte.This operation leads to saturation of the machine which the operator remedies by slightly opening the door which leads to obtaining a less well calibrated product, with a higher grain size, but also leads to abnormal wear of the door.

La présente invention a pour but de remédier à ces inconvénients
le croquis 1 représente une coupe d'un broyeur
le croquis 2 une porte conformément à l'invention
Le broyeur conformément à l'invention est constitué d'une caisse (1) à l'intérieur de laquelle évolue un rotor (2) équipé de marteaux (3). Le rotor (2) tourne suivant le sens indiqué par la flèche et chacun des marteaux (3) passe avec un jeu minimum en vis à vis d'une enclume (5). Les produits ainsi coincés entre le marteau et l'enclume sont déchiquetés puis projetés au travers de la grille supérieure (6) de sorte que les morceaux trop importants repassent de nouveau à l'intérieur du broyeur. Sur cette caisse, latéralement, est disposée une porte (7) qui ouverte permet l'élimination des imbroyables. Suivant l'invention, cette porte (7) présente une face (8) percée d'ouvertures (9) dont chacune est calibrée en fonction des ouvertures de la grille supérieure (6). De plus, le bord inférieur (10) est renforcé pour constituer un nez de rebondissement supplémentaire. Par ailleurs, pour éviter le coincement du produit à l'évacuation, les ouvertures (9) sont coniques avec la plus grande dimension dirigée vers l'extérieur du broyeur à l'opposé de la face (8). Cette présente invention permet de rebroyer le produit porte fermée sans pour autant saturer la machine et tout en préservant le rendement et la granulométrie. En utilisation courante, la porte joue toujours le même rôle, elle est ouverte pour évacuer les imbroyables, fermée, elle améliore encore le rendement de la machine. The object of the present invention is to remedy these drawbacks
sketch 1 represents a section of a grinder
sketch 2 a door according to the invention
The crusher according to the invention consists of a box (1) inside which a rotor (2) fitted with hammers (3) operates. The rotor (2) rotates in the direction indicated by the arrow and each of the hammers (3) passes with a minimum clearance opposite an anvil (5). The products thus wedged between the hammer and the anvil are shredded and then projected through the upper grid (6) so that the excessively large pieces pass back inside the crusher. On this box, laterally, there is a door (7) which opens allowing the elimination of unburnable. According to the invention, this door (7) has a face (8) pierced with openings (9) each of which is calibrated as a function of the openings of the upper grid (6). In addition, the lower edge (10) is reinforced to form an additional rebound nose. Furthermore, to avoid jamming of the product during evacuation, the openings (9) are conical with the largest dimension directed towards the outside of the mill opposite the face (8). This present invention makes it possible to regrind the product with the door closed without saturating the machine and while preserving the yield and the particle size. In current use, the door always plays the same role, it is open to evacuate the unburnable, closed, it further improves the efficiency of the machine.
