Claims (2)
1. Kontinuerligt förfarande för framställning av gipsplatta, varvid en begränsad mängd vatten används för att fluidisera bränt gips väsentligen bestäende av kalciumsulfathemihydrat vid formning av en gipsmassa, som mätäs tili framställningsmaskineriet för gipsplatta och som sälunda kräver mindre energi för torkning av den väta plattan, och vilket förfarande omfattar följande vid framställning av gipsplatta normala steg: (1) matning av bränt gips levereras för transport tili en gipsmassablandare; (2) det brända gipset och vatten blandas i massablandaren tili en homogen massa; (3) massan mätäs tili framställningsmaskinen för gipsplatta för bildande av en vät gipsplatta; (4) den väta gipsplattan förs genom en ugn för torkning av plattan; och (5) en torr gipsplatta erhälles, som väsentligen bestär av kalciumsulfatdihydrat; och vilket förfarande ärkännetecknat därav, att (6) det brända gipset tillförs i sin helhet tili blandaren; (7) en liten mängd vatten inblandas i det brända gipset i blandaren, vilken vattenmängd är cirka 1 - cirka 8 vikt-% av den totala matningen av bränt gips; (8) det fuktade brända gipset frän blandaren fär stillna, och det stillnade fuktade brända gipset mätäs tili gipsmassablandaren; och (9) tili den stillnade, fuktade blandningen av bränt gips i massablandaren tillsätts ytterligare vatten i en sadan mängd, som är just tillräcklig för att ge gipsmassan lämplig strömning och en väsentligen minskad mängd vatten för avdunstning frän den väta plattan i ugnen.
2. Förfarande enligt patentkravet 1,kännetecknat därav, att temperaturen i ugnen, som används för torkning av skivan, är ätminstone 20°C lägre än drifttemperaturen i en normal brännugn, tili följd av gipsmassans lägre vattenhalt.
