VERFAHREN ZUR HERSTELLUNG EINES FUER DIE PRODUKTION VON GIPSKARTONPLATTEN GEEIGNETEN STUCKGIPSES AUS REA-GIPS |
摘要 |
<p>A process for the preparation of gypsum stucco suited for the production of plasterboard from gypsum obtained in flue gas desulfurisation units by drying, burning in a conical digester, grinding at high energy input in a ball mill or vibratory mill and subsequent treatment with small quantities of water of 1-8% by weight, preferably 5% by weight, and a residence time of 1-3 minutes before feeding into the gypsum mixer is described. A part of the gypsum stucco can here be replaced by unburned gypsum from flue gas desulfurisation units. The subsequent processing is then the same as is generally usual in plasterboard manufacture.</p> |
