Beschreibung
Zusammenfassung:	The present invention relates to a process for comminuting glass fibers from waste glass-based fibrous materials, comprising the process steps of a) coarsely comminuting the glass fibers to obtain coarsely comminuted glass fibers; and b) finely comminuting said coarsely comminuted glass fibers with a granular additive having a d50 value within a range of from 0.1 to 5.0 mm as an aggregate to obtain finely comminuted glass fibers, the mixing ratio of glass fibers to additive being from 25/75 to 95/05 by weight. La présente invention porte sur un procédé pour fragmenter des fibres de verre issues de déchets de fibres de verre, comprenant les étapes suivantes : a) fragmentation grossière des fibres de verre pour donner des fibres de verre grossièrement fragmentées ; et b) fragmentation fine des fibres de verre grossièrement fragmentées avec un additif granulaire ayant une granulométrie d50 de 0,1à 5,0 mm en tant qu'additif, afin d'obtenir des fibres de verre finement fragmentées, le rapport à l'intérieur du mélange des fibres de verre par rapport à l'additif valant de 25/75 à 95/05 % en poids.
