Abstract (en)
[origin: WO2011087373A1] A method and a device for producing foamed glass are described, where glass/cullet is introduced into a melting chamber (3) using a feed screw (2) and molten glass is passed into the extrusion chamber (7) by the feed screw (5) through the feed housing / tube (6) for subsequent extrusion, where foaming agent or an expansion additive is supplied under positive pressure by feed screw (13) and (13.1) and mixed with molten glass in the introduction phase of the extrusion chamber (7) by the feed screw (5) and finally mixed by mixer (8) prior to expansion of foamed glass through adjustable nozzles (10) for cooling.
