Process for Preparing Foamed Glass Granulate

Abstract

A process for preparing foamed glass granulate comprises the following steps: provision of an aqueous glass binder slurry containing water at room temperature, a foaming agent and a glass binder in a preparation tank, addition of glass powder, preferably old glass powder, to the glass binder slurry to form a moist stirrable glass preparation, homogenisation of the glass preparation thus formed, transfer of the glass preparation into a stirring tank, stirring of the glass preparation for a stirring period of between 2 and 6 hours to fuse the glass components at least in part, addition of further glass powder to the glass preparation in a granulation mixer to form granulate green bodies, drying of the granulate green bodies and foaming of the granulate green bodies into foamed glass granulate particles.
