Abstract
A method for preparing a raw material composition adapted to be fed into the melting chamber of a facility adapted to obtain cullet, glass wool and/or rock wool, textile glass yarns, flat glass and/or hollow glass, the method including grinding a mineral wool mixture adapted to enter into the raw material composition, such that the granular mixture obtained after grinding has a bulk density greater than or equal to 30 kg/m3.
Claims29
A raw material composition suitable for being fed into the melting chamber of an installation suitable for obtaining cullet, glass wool and/or rock wool, textile glass yarns, flat glass and/or hollow glass, the raw material composition comprising:
- a granular mixture comprising ground fibers of a mineral wool mixture, the granular mixture having a bulk density greater than or equal to 70 kg/m3 and less than or equal to 500 kg/m3, and a mass of cullet of at least 1% of the total mass of the granular mixture;
- wherein said mineral wool mixture of said ground fibers has a moisture content greater than 1% of the total mass of said mixture, the moisture being water.
