Abstract

Metoder og systemer tilveiebringes for fremstilling av en varmeresistent akselerator(HRA)slurry. Også tilveiebrakt er metoder og systemer for innføring av en HRA slurry til en vandig dispersjon av kalsinert gips i et tappeapparat nedstrøms fra en stukkaturblander hvori dispersjonen ble fremstilt. Disse metoder og systemer er nyttige i produksjon av forskjellige gipsprodukter som for eksempel gipsplater for vegger og tak.
