METHOD FOR PRODUCING A GRANULATE OF WASTE GLASS AND ITS USE FOR THE MANUFACTURE OF MINERAL WOOL PRODUCTS

摘要

The present invention relates to a method for producing a granulate from waste glass for the manufacture of mineral wool products, obtained with the aid of at least one spinner having the form of a spinner basket, the peripheral wall of which includes a multiplicity of small-diameter outlet orifices through which a molten glass material is spun off in the form of filaments that are subjected to a supplementary attenuating action of a preferably downwardly directed gas flow, wherein a part of the molten glass material is constituted by glass fragments including impurities like ceramic proportions in a ground form, the granulometry of which is the same size or smaller than the smallest diameter of the outlet orifices in the peripheral wall of the spinner.
