Abstract

Appareil et procédé d'élimination des impuretés d'une matière première. Il comporte une surface sur laquelle la matière tombe, un détecteur des vibrations que le choc de cette matière fait subir à cette surface et un circuit électronique ne laissant passer que les signaux que le détecteur émet quand les vibrations sont provoquées par des impuretés, les signaux émis par ce circuit actionnant une plaque déviatrice disposée en aval de la surface de manière qu'elle interrompe l'écoulement de la matière et envoie vers un récipient distinct la partie de cette matière qui contient des impuretés, et des circuits temporisateurs qui ramènent ensuite cette plaque à sa position inactive. Application à la separation de pierres et fragments métallique mélangés à des copeaux de bois destinés à la fabrication de pâte à papier.
