Abstract

Dispositif pour le dosage continu du taux d'humidité dans les assortiments fins de minéraux, notamment dans le charbon fin, directement sur le transporteur à bande, par une méthode à réflexion utilisant le rayonnement électromagnétique du domaine des micro-ondes, pouvant être utilisé dans les centrales électriques et dans les ateliers de traitement des minéraux, dispositif comprenant un convertisseur à micro-ondes 3 qui convertit le rayonnement du domaine des micro-ondes en un signal électrique, connecté à un détecteur de réflexion 2, ces deux éléments étant placés sur une construction pendulaire 1 équipée d'un patin 9 placé directement sur la surface du minéral 10 déplacé sur un transporteur à bande 11. Le convertisseur à micro-ondes 3 est connecté à un ensemble de mesure 4, dont la sortie est connectée par des cables au bloc 5 de détermination de la moyenne et de visualisation du résultat numérique.Device for the continuous determination of the moisture content in fine assortments of minerals, in particular in fine coal, directly on the conveyor belt, by a reflection method using electromagnetic radiation from the microwave range, which can be used in power stations and in mineral processing workshops, device comprising a microwave converter 3 which converts radiation from the microwave domain into an electrical signal, connected to a reflection detector 2, these two elements being placed on a pendulum construction 1 equipped with a pad 9 placed directly on the surface of the mineral 10 moved on a conveyor belt 11. The microwave converter 3 is connected to a measuring assembly 4, the output of which is connected by cables in block 5 for determining the average and displaying the digital result.
