Description

La présente invention concerne les broyeurs dans lesquels la matière est broyée entre un cône et une cuve tronconique sans fond entourant le cône, les surfaces de travail du cône et de la cuve étant garnies d'un revêtement anti-usure, et dans lesquels la cuve est montée sur un châssis mobile par rapport au bâti et équipé de moyens aptes à communiquer à la cuve des vibrations ou oscillations circulaires et approximativement horizontales qui provoquent, successivement dans tous les plans radiaux, le rapprochement puis l'éloignement du cône et de la cuve. Les moyens utilisés pour faire vibrer ou osciller la cuve peuvent être des vibrateurs à balourd, des vibrateurs électro-magnétiques, etc... Un broyeur de ce type est connu du document FR-A-2 687 080.The present invention relates to mills in which the material is ground between a cone and a bottomless frusto-conical tank surrounding the cone, the cone's working surfaces and the tank being lined with an anti-wear coating, and in which the tank is mounted on a chassis movable relative to the frame and equipped with means capable of communicating with the tank of circular and approximately horizontal vibrations or oscillations which cause, successively in all the radial planes, the approximation then the distance of the cone and of the tank. The means used to vibrate or oscillate the tank can be vibrators with unbalance, electro-magnetic vibrators, etc. A grinder of this type is known from document FR-A-2 687 080.

Dans leur principe, ces appareils sont connus depuis longtemps, mais en pratique ils ont été peu utilisés. Dans les appareils connus de ce type, le cône est fixé rigidement sur son support. Or, les mouvements de rapprochement et d'éloignement du cône et de la cuve, qui provoquent l'écrasement de la matière à broyer, s'accompagnent, du fait des mouvements circulaires de la cuve, de déplacements relatifs parallèles aux plans tangentiels qui entraínent une instabilité de la machine et une usure rapide des surfaces de travail du cône et de la cuve. Par ailleurs, les appareils connus se prêtent mal à une conduite automatisée permettant d'obtenir des produits de granulométrie donnée.In principle, these devices have been known for a long time, but in practice they have been little used. In known devices of this type, the cone is rigidly fixed on its support. However, the movements of approach and away from the cone and the tank, which cause crushing of the material to be ground, accompany each other, due to movements circular of the tank, relative displacements parallel to the tangential planes which entail machine instability and rapid wear of the cone and tank work surfaces. Furthermore, the known devices do not lend themselves to automated driving allowing to obtain products with a given particle size.

Le but de la présente invention est de permettre un contrôle de la marche du broyeur et une meilleure surveillance de son état, tout en augmentant la durée de vie des surfaces de travail.The object of the present invention is to allow a control of the operation of the mill and better monitoring of its condition, while increasing the life of the surfaces of job.

Le broyeur objet de la présente invention est caractérisé en ce que le cône est monté sur le bâti de façon à pouvoir tourner librement autour de son axe et est équipé de moyens de mesure de sa vitesse de rotation autour de son axe, lié fonctionnellement à un système de réglage des paramètres fréquence et/ou amplitude des vibrations ou oscillations de la cuve.The mill object of the present invention is characterized in that the cone is mounted on the frame so that it can rotate freely around its axis and is equipped with means for measuring its speed of rotation about its axis, functionally linked to a system for adjusting the frequency and / or amplitude of the vibrations or oscillations of the tank.

Connaissant la vitesse de rotation du cône, on peut déterminer, pour un réglage donné du broyeur (largeur de la fente annulaire dans le plan de sortie des matières broyées), l'épaisseur de la couche de matières dans le plan de sortie des matières broyées et, si nécessaire, la modifier par réglage de la fréquence et/ou de l'amplitude des moyens de mise en vibrations de la cuve et/ou de la position en hauteur du cône, pour obtenir un produit broyé ayant la granulométrie voulue ; ces moyens permettent d'automatiser la marche du broyeur. Par ailleurs, pour des réglages donnés de la fréquence et de l'amplitude des moyens de mise en vibrations de la cuve et de la largeur de la fente de sortie, l'évolution de la vitesse de rotation du cône permet de détecter l'usure des surfaces de travail du cône et de la cuve.Knowing the speed of rotation of the cone, we can determine, for a given adjustment of the grinder (width of the annular slot in the outlet plane of the comminuted material), the thickness of the layer of material in the outlet plane of the comminuted material and, if necessary, modify it by adjusting the frequency and / or the amplitude of the setting means in vibrations of the tank and / or of the height position of the cone, to obtain a product ground with the desired particle size; these means automate the operation of the grinder. Furthermore, for given adjustments of the frequency and amplitude of the means of vibration of the tank and the width of the outlet slot, the evolution of the speed of cone rotation makes it possible to detect the wear of the working surfaces of the cone and of the tank.

L'invention a également pour objet un procédé de réglage d'un broyeur du type défini ci-dessus consistant à mesurer la vitesse de rotation du cône autour de son axe, à déterminer l'épaisseur minimale de la couche de matières dans le plan de sortie des matières broyées à partir de la valeur mesurée de la vitesse de rotation du cône et de la largeur de la fente annulaire existant dans ce plan entre le cône et la cuve quand le broyeur est au repos, et à régler la fréquence et/ou l'amplitude des vibrations ou oscillations de la cuve pour maintenir l'épaisseur minimale de la couche de matières égale à une valeur de consigne.The invention also relates to a method for adjusting a grinder of the defined type. above consisting in measuring the speed of rotation of the cone around its axis, to be determined the minimum thickness of the material layer in the outlet plane of the comminuted material at from the measured value of the speed of rotation of the cone and the width of the slot annular existing in this plane between the cone and the tank when the mill is at rest, and at adjust the frequency and / or amplitude of the vibrations or oscillations of the tank to maintain the minimum thickness of the material layer equal to a set value.

La description qui suit se réfère au dessin qui l'accompagne et montre, à titre d'exemple non-limitatif, une forme de réalisation de l'invention. Sur ce dessin :

  • La figure 1 est une vue de dessus d'un broyeur à cône vibrant réalisé conformément à l'invention ; et
  • La figure 2 est une vue en coupe verticale, suivant A-A, du broyeur de la figure 1;
    • The following description refers to the accompanying drawing and shows, by way of non-limiting example, an embodiment of the invention. On this drawing :
  • Figure 1 is a top view of a vibrating cone crusher produced in accordance with the invention; and
  • Figure 2 is a vertical sectional view along AA of the crusher of Figure 1;

    • Dans le broyeur des figures 1 et 2, le cône 10 est monté, par l'intermédiaire de roulements 14, sur un bout d'arbre 12 qui est supporté par un bâti 16 ; ce montage permet une libre rotation du cône autour de son axe. Le bâti 16 est monté sur un système élastique 30 réduisant la transmission au sol des efforts et des vibrations. Pour réduire l'amplitude des vibrations du bâti, celui-ci pourrait être équipé de moyens de mise en vibrations le soumettant à des efforts en opposition de phase avec ceux provenant de la cuve 18 pendant le broyage. Le bâti 16 pourrait être monté directement sur un massif correctement dimensionné.In the crusher of Figures 1 and 2, the cone 10 is mounted, by means of bearings 14, on a shaft end 12 which is supported by a frame 16; this assembly allows free rotation of the cone around its axis. The frame 16 is mounted on an elastic system 30 reducing the transmission to the ground of stresses and vibrations. To reduce the amplitude of vibrations of the frame, it could be equipped with means of vibration subjecting it to efforts in phase opposition with those from the tank 18 during grinding. The frame 16 could be mounted directly on a properly dimensioned solid.

    La cuve 18 est fixée sur un châssis 20 supporté par une série de bielles 22 dont les extrémités sont articulées sur le châssis et le bâti.The tank 18 is fixed to a frame 20 supported by a series of connecting rods 22, the ends are articulated on the frame and the frame.

    Des vibrateurs à balourd 24 sont montés sur le châssis 20. Ils sont entraínés en synchronisme de façon à provoquer des mouvements circulaires horizontaux de faible amplitude de l'ensemble châssis-cuve. L'entraínement se fait par le biais d'un mécanisme comportant des courroies 36, des galets tendeurs 38, des poulies motrices 40, des cardans 42, un moteur 46 et un dispositif de déphasage 44 du type décrit dans le brevet français n° 92 01642 (n° de publication 2 687 080) et permettant de régler l'amplitude des vibrations. Le moteur 46 est équipé d'un variateur de vitesse permettant de régler la fréquence des vibrations. Unbalance vibrators 24 are mounted on the chassis 20. They are driven in synchronism so as to cause low horizontal circular movements amplitude of the chassis-tank assembly. The training is done through a mechanism comprising belts 36, tension rollers 38, drive pulleys 40, cardan joints 42, a motor 46 and a phase shift device 44 of the type described in French patent n ° 92 01642 (publication number 2 687 080) and used to adjust the amplitude vibrations. The motor 46 is fitted with a variable speed drive which makes it possible to adjust the frequency of vibrations.

    Les mouvements vibratoires de l'ensemble châssis-cuve provoquent le rapprochement périodique de la cuve et du cône dans chaque plan radial et, par conséquent, l'écrasement de la matière entre la cuve et le cône. Il se forme sur la surface intérieure de la cuve une couche de matière dont l'épaisseur dépend du débit et de la fréquence et de l'amplitude des vibrations. Cette couche se déplace vers le bas de la cuve et les produits broyés sont évacués a travers la fente de sortie et tombent dans une trémie collectrice placée sous le broyeur, a travers un passage annulaire ménagé dans le bâti.The vibratory movements of the chassis-tank assembly cause the approximation periodic of the tank and the cone in each radial plane and, consequently, the crushing of the material between the tank and the cone. A layer is formed on the inner surface of the tank of material whose thickness depends on the flow rate and the frequency and amplitude of the vibrations. This layer moves to the bottom of the tank and the crushed products are discharged through the outlet slot and fall into a collecting hopper placed under the mill, a through an annular passage formed in the frame.

    Les mouvements de la cuve s'accompagnent d'une rotation du cône 10 autour de son axe sous l'action des efforts tangentiels exercés par la cuve, par l'intermédiaire de la matière à broyer. Cette rotation permet d'obtenir un procédé de fragmentation stable et de réduire fortement l'usure des blindages du cône et de la cuve.The movements of the tank are accompanied by a rotation of the cone 10 around its axis under the action of tangential forces exerted by the tank, through the medium to grind. This rotation provides a stable fragmentation process and reduces heavy wear on the cone and tank shields.

    Le broyeur est équipé d'un système 26 de réglage en hauteur du cône par rapport à la cuve 18, par exemple un système à vis et écrou ou un vérin hydraulique. Ce système permet de régler la largeur de la fente annulaire existant entre le cône et la cuve dans le plan de sortie 34 des matières broyées ; lorsque le broyeur est au repos, cette fente a une largeur constante sur toute sa périphérie et égale à la différence des rayons du cône et de la cuve dans le plan de sortie 34.The mill is equipped with a system 26 for adjusting the height of the cone relative to the tank 18, for example a screw and nut system or a hydraulic cylinder. This system allows to adjust the width of the annular gap existing between the cone and the tank in the plane outlet 34 of the ground material; when the mill is at rest, this slot has a width constant over its entire periphery and equal to the difference of the radii of the cone and of the vessel in the exit plan 34.

    En cours de broyage, il se forme entre le cône et la cuve une couche de matière dont l'épaisseur minimale, définie par l'écart minimal entre cône et cuve dans le plan de sortie, est fonction du réglage initial de la position en hauteur du cône par rapport à la cuve et de l'amplitude et de la fréquence des vibrations. La granulométrie des produits broyés dépend de l'épaisseur minimale de la couche de matières et il est donc possible de contrôler la qualité des produits broyés en réglant l'amplitude ou la fréquence des vibrateurs, et dans une certaine mesure la position en hauteur du cône, au moyen du système 26.During grinding, a layer of material is formed between the cone and the tank. the minimum thickness, defined by the minimum distance between cone and tank in the outlet plane, is function of the initial adjustment of the height position of the cone relative to the tank and of the amplitude and frequency of the vibrations. The grain size of the ground products depends the minimum thickness of the material layer and it is therefore possible to control the quality crushed products by adjusting the amplitude or frequency of the vibrators, and within a certain measures the height position of the cone, using system 26.

    Un dispositif 28 de mesure de la vitesse de rotation du cône, tel qu'un capteur à induction magnétique (marque IFM - type IFK3004 BP0G par exemple), permet de connaítre en permanence cette grandeur et, connaissant la valeur de réglage de la largeur de la fente annulaire de sortie, d'en déduire l'épaisseur de la couche de matières.A device 28 for measuring the speed of rotation of the cone, such as a sensor with magnetic induction (brand IFM - type IFK3004 BP0G for example), allows to know permanently this quantity and, knowing the setting value of the width of the slit annular outlet, to deduce the thickness of the layer of materials.

    La vitesse de rotation du cône est donnée par la formule : N = Kn.(f-e)D.cos α avec

    K =
    constante
    n =
    fréquence des vibrations (vitesse de rotation des vibrateurs)
    f =
    valeur de réglage de la fente annulaire de sortie
    e =
    épaisseur de la couche
    α =
    ½ angle au sommet du cône
    The speed of rotation of the cone is given by the formula: N = K n. (fe) D.cos α with
    K =
    constant
    n =
    frequency of vibrations (speed of rotation of vibrators)
    f =
    setting value of the output annular slot
    e =
    layer thickness
    α =
    ½ angle at the top of the cone

    Cette formule permet de calculer e, de comparer la valeur obtenue à une valeur de consigne et, si nécessaire, de régler l'amplitude et/ou la fréquence des vibrations ou la largeur f de la fente.This formula makes it possible to calculate e, to compare the value obtained with a value of setpoint and, if necessary, adjust the amplitude and / or frequency of the vibrations or the width f of the slot.

    On peut donc automatiser la conduite du broyeur, pour obtenir des produits broyés ayant la granulométrie voulue, au moyen d'un automate ou d'un calculateur 32 qui reçoit les informations du capteur 28 et qui peut envoyer des instructions au dispositif de déphasage 44 et au moteur 46 pour régler l'amplitude et/ou la fréquence des vibrations, et au système 26 pour modifier la position en hauteur du cône.We can therefore automate the operation of the crusher to obtain crushed products having the desired particle size, by means of an automaton or a computer 32 which receives the information from the sensor 28 and which can send instructions to the phase shift device 44 and to the motor 46 for adjusting the amplitude and / or the frequency of the vibrations, and to the system 26 to change the height position of the cone.

    Comme expliqué plus haut, on peut aussi, en observant les variations de la vitesse de rotation du cône dans des conditions de marche données, détecter l'usure des surfaces de travail du cône et de la cuve.As explained above, it is also possible, by observing the variations in the speed of cone rotation under given operating conditions, detect wear on the cone and tank work.

    Il est bien entendu que les modifications qui peuvent être apportées aux formes de réalisation décrites, par l'emploi de moyens techniques équivalents, et relatifs, notamment, au montage rotatif du cône sur le bâti et aux moyens de mise en vibrations de la cuve entrent dans le cadre de l'invention comme définie par les revendications.It is understood that the modifications which can be made to the forms of realization described, by the use of equivalent technical means, and relative, in particular, when the cone is rotatably mounted on the frame and the means for vibrating the tank enter in the context of the invention as defined by the claims.
