Title
(DE) VERFAHREN ZUR REGELUNG EINES BRECHERS
(EN) METHOD FOR CONTROLLING A CRUSHER
(FR) PROCÉDÉ POUR RÉGLER UN CONCASSEUR
Abstract
(DE) Es wird ein Verfahren zur Regelung eines Brechers mit einem Brechwerkzeug und einem einen Antrieb (5) aufweisenden Schwingförderer (1), wobei in einem Erfassungsbereich (4) liegendes Schüttgut (2) mit einem Sensor (3) erfasst wird, beschrieben. Damit bei Körnen mit inhomogener Korngrößenverteilung auch große Körner bei gleichbleibendem Brechergebnis gebrochen werden können, ohne dass eine Gefahr der Beschädigung des Brechers besteht, wird vorgeschlagen, dass als Regelgröße ein sich aufgrund des größten Durchmessers dmax und seiner Richtung (9) ergebender effektiver Durchmessers deff quer zur Förderrichtung (8) eines Kornes des Schüttguts (2) im Erfassungsbereich (4) bestimmt wird und dass bei Überschreiten des effektiven Durchmessers deff über einen vorgegebenen Leistungsschwellwert die Leistung des Brechwerkzeugs erhöht und/oder bei Überschreiten des effektiven Durchmessers deff über einen vorgegebenen Abschaltgrenzwert der Antrieb (5) abgeschaltet wird.
(EN) A description is given of a method for controlling a crusher having a crushing tool and a vibratory conveyor (1) having a drive (5), wherein bulk material (2) in a capture region (4) is captured using a sensor (3). So that, in the case of grains with an inhomogeneous grain size distribution, even large grains can be crushed with a constant crushing result without there being a risk of the crusher being damaged, it is proposed that an effective diameter deff, which results from the largest diameter dmax and the direction (9) thereof, transverse to the conveying direction (8) of a grain of the bulk material (2) is determined as the controlled variable in the capture region (4) and that, if the effective diameter deff exceeds a predefined power threshold value, the power of the crushing tool is increased and/or, if the effective diameter deff exceeds a predefined switch-off limit value, the drive (5) is switched off.
(FR) L'invention concerne un procédé pour régler un concasseur comprenant un outil de concassage et un convoyeur vibrant (1) qui présente un entraînement (5), du produit en vrac (2) présent dans une zone de détection (4) étant détecté au moyen d'un capteur (3). L'invention a pour objet de permettre, dans le cas de fragments ayant une répartition de taille de fragments non homogène, le concassage des fragments de grande taille jusqu'à obtention d'un résultat de concassage identique, sans risque d'endommagement du concasseur. À cet effet, en tant que taille de réglage est déterminé un diamètre effectif deff résultant du plus grand diamètre dmax et de sa direction (9), transversalement à la direction d'acheminement (8) d'un fragment du produit en vrac (2) dans la zone de détection (4), et, lorsque le diamètre effectif deff dépasse une valeur seuil de puissance préétablie, la puissance de l'outil de concassage est augmentée, et/ou lorsque le diamètre effectif deff dépasse une valeur seuil d'arrêt préétablie, l'entraînement (5) est arrêté.
