Abstract

Appareil et procédé mis en oeuvre pour sélectionner et trier certains objets ou produits en grains ou en blocs, en utilisant la propriété qu'ils ont de diffuser certaines radiations. Il comprend une station d'irradiation 19, un dispositif photomultiplicateur 21, qui, sous l'effet des radiations diffusées, entraîne par l'intermédiaire d'un système électronique 23 la commande d'un dispositif d'éjection 24. L'invention peut être utilisée pour le triage industriel du quartz.
