Abstract

a invenção refere-se a um método e a um dispositivo para a produção de microesferas de vidro ocas (3.4) de vidro fundido (3), sendo que as microesferas de vidro ocas (3.4) na faixa de diâmetro de 0,01 mm a 0,1 mm são fabricadas em um processo de trabalho contínuo mediante prevenção de formação de filamentos de vidro. fios de vidro (3.1) fundidos que saem de um dispositivo de fusão superficial (1) são pulverizados por meio de gás de aquecimento (14) em partículas de gás (3.2). em seguida, durante a passagem através de um canal de moagem cilíndrica/expansão (6), ocorre a moagem cilíndrica das partículas de vidro (3.2) em microesferas de vidro maciças (3.3) e a sua expansão em microesferas de vidro ocas (3.4). as microesferas de vidro ocas (3.4) podem ser utilizadas vantajosamente como carga para matérias-primas de construção leve ou como constituintes de vernizes, tintas e gessos.
