Gypsum - BCE

Soil conditioner (known as landplaster) uses raw gypsum that does not need to be calcined. It is produced by crushing the raw product to less than 2″, then grinding and drying in a roller mill so that at least 90% is < 100 mesh. The ground gypsum leaves the mill and is conveyed to a dust collector. Calcining


A process for producing a healed stucco of low water demand is disclosed in which calcined gypsum is treated with an aqueous solution of a gypsum solubilizing agent, preferably in an impacting blender while grinding the calcined gypsum to increase its surface area. The product can be dried for storage or sent directly to forming gypsum board.
