Abstract (en)
[origin: CA3028838A1] The invention relates to a method and a device for producing hollow microglass beads (3.4) from molten glass (3), wherein the hollow microglass beads (3.4) are manufactured in a diameter range from 0.01 mm to 0.1 mm in a continuously operating process while avoiding glass filament formation. Molten glass strands (3.1) exiting a melting device (1) are atomized by means of hot gas (14) to form glass particles (3.2). Subsequently, during passage through a rounding/expansion duct (6), the glass particles (3.2) are rounded to form solid microglass beads (3.3) and expanded to form hollow microglass beads (3.4). The hollow microglass beads (3.4) can advantageously be used as a filler for lightweight building materials or as a constituent part of coatings, paints and plasters/renders.
