The invention relates to a method for the production of foamed glass granulate, comprising the following steps: an aqueous glass binder slop which contains water is prepared at room temperature, and a propellant and a glass binder is prepared in an additional container, glass powder, preferably, old glass powder is added to the glass binder slop in order to form a humid, stirrable glass preparation, the thus formed glass preparation is homogenised, is added to a stirring container and is stirred during a stirring time which is between 2 and 6 hours in order to at least partially decompose the glass components, additional glass powder is added to the glass preparation in a granulate mixer in order to form granulate green bodies which are then dried and are foamed in order to form foamed glass granulate particles.
L'invention concerne un procédé de fabrication de granulat de verre mousse consistant à mettre en oeuvre une bouillie de liant de verre aqueuse à température ambiante, contenant de l'eau, un agent propulseur et un liant de verre dans un récipient de préparation ; à additionner du verre pulvérisé, de préférence du verre usé pulvérisé, à la bouillie de liant de verre de manière à former une préparation de verre humide, miscible ; à homogénéiser la préparation de verre ainsi formée ; à amener la préparation de verre dans un contenant de mélange ; à mélanger la préparation de verre entre 2 et 6 heures afin de dissoudre au moins partiellement les composants de verre ; à additionner une autre fraction de verre pulvérisé à la préparation de verre dans un mélangeur de granulation afin de former des corps de base de granulat ; à sécher les corps de base de granulat ; et, à mousser les corps de base de granulat afin de former des particules de granulat de verre mousse.
