Title (EN) METHOD AND DEVICE FOR THE AUTOMATIC CONTROL OF A CYLINDER MILL PROVIDED WITH A PRODUCT SUPPLY REGULATOR
(FR) PROCEDE ET DISPOSITIF DE COMMANDE AUTOMATIQUE D"UN MOULIN A CYLINDRE MUNI D"UN REGULATEUR D"ALIMENTATION DU PRODUIT
Abstract: front page image
(EN)According to the method, a mechanical control signal is generated according to the product supply for the control of a metering valve (9). To obtain powerful control operation with a high precision and reliability and of a simple and compact construction, the mechanical control signal is first transformed into a pneumatic signal which is transmitted as an input signal to a servocontrol (41) for regulating the product supply and/or to a servocontrol (18) for the start up or shut down of the milling cylinder. A device specially adapted to this method is a cylinder mill which comprises a mechanical signal transmitter (13, 15) operating a pneumatic regulating valve (17) of which the output is connected to the input of a servocontrol (18) actuating the metering valve (9) and/or the start up and shut down of milling cylinders (1, l", 2, 2").
(FR)Selon le procede, on cree un signal de commande mecanique en fonction de l"alimentation du produit pour la commande de la valve de dosage (9). Pour obtenir des operations de commande puissantes de grande precision et de haute fiabilite avec une construction simple et compacte, on transforme d"abord le signal de commande mecanique en un signal pneumatique qui est transmis comme signal d"entree a une servocommande (41) pour le reglage de l"alimentation du produit et/ou a une servocommande (18) pour l"enclenchement et le declenchement du cylindre de broyage. Un dispositif specialement adapte a ce procede est un moulin a cylindre qui comprend un transmetteur de signaux mecaniques (13, 15) actionnant une valve de reglage pneumatique (17), dont la sortie est reliee a une entree d"une servocommande (18) actionnant la valve de dosage (9) et/ou l"enclenchement et le declenchement des cylindres de broyage (1, 1", 2, 2").
