Abstract

The grinder comprises a frame (1) forming the bedplate, with a gyratory mechanism (4) in its central lower part supporting a grinding cone (3). A cupola (5) is fixed on the top of the frame. A set of oleopneumatic safety actuators (6), whose stroke is adjusted by a pump (8), act as springs. An adjusting actuator assembly (7) is connected to another pump (9). A sliding assembly (2) adjusts and grades the products, acting as a safety valve in the case of the passage of non-grindable bodies into a grinding chamber (0). The sliding assembly is driven by the oleopneumatic arrangement. A system of conical annular segments (10) connects the frame and the cupola under the action of the oleopneumatic system. This, automatically stabilises the sliding assembly in its operating position.

Description

La présente invention concerne un dispositif de broyage de matériaux, à réglage de calibrage et sécurité télescopique asservie par des moyens oléopneumatiques.The present invention relates to a material grinding device, with calibration adjustment and telescopic safety controlled by oleopneumatic means.

Sur les broyeurs les plus évolués, le réglage de calibrage des produits à obtenir s'effectue par des moyens mécaniques (vis et écrous). La sécurité, en cas de passage de corps imbroyables dans l'apparil, étant assurée par un système de ressorts.On the most advanced grinders, the calibration adjustment of the products to be obtained is carried out by mechanical means (screws and nuts). Safety, in the event of passage of unburnable bodies in the apparatus, being ensured by a system of springs.

Ces appareils, de par leur conception, nécessitent, lors de réglages, des interventions relativement longues.These devices, by design, require relatively long interventions during adjustments.

Ils existent cependant des appareils à pivot central coulissant avec réglage hydraulique, mais leur conception en fait des appareils fragiles.However, there are sliding central pivot devices with hydraulic adjustment, but their design makes them fragile devices.

Le dispositif, objet de l'invention, permet d'avoir une machine robuste, performante, dont la particularité reside essentiellement dans son système télescopique oléopneumatique muni d'un mécanisme d'auto-serrage assurant sa stabilisation en position de travail. The device, object of the invention, makes it possible to have a robust, efficient machine, the particularity of which resides essentially in its telescopic oleopneumatic system provided with a self-tightening mechanism ensuring its stabilization in the working position.

L'appareil objet de l'invention se compose:
D'un bâti (1) constituant l'assise de l'appareil et renfermant en sa partie centrale basse le mécanisme giratoire excentré (4) supportant le cône de broyage (3).The device which is the subject of the invention consists of:
A frame (1) constituting the seat of the device and enclosing in its lower central part the eccentric gyratory mechanism (4) supporting the grinding cone (3).

D'une coupole (5) emboîtée sur le dit bâti (1) et fixée sur ce dernier.A dome (5) fitted on said frame (1) and fixed on the latter.

D'un ensemble de vérins de sécurité oléopneumatiques (6) à course réglable grâce à la pompe (8), ces vérins faisant office de ressorts.A set of oleopneumatic safety cylinders (6) with adjustable stroke thanks to the pump (8), these cylinders acting as springs.

D'un ensemble de vérins de réglage (7) reliés entre eux et à la pompe (9).A set of adjustment cylinders (7) connected to each other and to the pump (9).

D'un ensemble mobile coulissant (2) constituant le dispositif de réglage et calibrage des produits à obtenir et assurant en outre la fonction de soupape de sécurité en cas de passage de corps imbroyables dans la chambre de concassage (O). Cet ensemble mobile (2) peut être mû par un agencement de moyens oléopneumatiques (6.7.8.9).A sliding mobile assembly (2) constituting the device for adjusting and calibrating the products to be obtained and also ensuring the function of safety valve in the event of passage of unburnable bodies in the crushing chamber (O). This mobile assembly (2) can be moved by an arrangement of oleopneumatic means (6.7.8.9).

D'un système de segments annulaires coniques (10) assurant la liaison entre le bâti (1) et la coupole (5) sous l'action conjugée des moyens oléopneumatiques (6.7.8.9), permettant ainsi lautostabilisation de l'ensemble mobile (2) en position de travail.A system of conical annular segments (10) ensuring the connection between the frame (1) and the dome (5) under the combined action of oleopneumatic means (6.7.8.9), thus allowing the self-stabilization of the mobile assembly (2 ) in working position.

Le dispositif selon l'invention est destiné au broyage des matériaux. The device according to the invention is intended for grinding materials.
