Abstract

Dispositif pour la mesure en continu de la quantité de charbon à l'intérieur d'un broyeur à boulets, caractérisé en ce qu'il comprend un émetteur (35) d'une onde, choisie parmi les ondes ultrasonores et électromagnétiques, un récepteur (36) de l'onde, l'émetteur et le récepteur étant disposés de manière que l'onde traverse au moins en partie l'intérieur du broyeur, le récepteur (35) étant associé à un circuit électronique déduisant la quantité de charbon de la comparaison du signal reçu avec des données issues de mesures préalables d'étalonnage.
