Abstract

PURPOSE: To manufacture granular gypsum hard to disintegrate and powder and easy to handle by adding a specified amt. of fermentation waste liquor or wood digesting waste liquor as a granulating aid to gypsum powder based on CaSO4. 2H2O followed by granulation.
CONSTITUTION: To gypsum powder based on CaSO4.2H2O is added fermentation waste liquor, as a granulating aid, discharged from alcohol fermentation, etc., wood digesting waste liquor from production of kraft pulp, etc., or dried powder thereof so that 0.5W13, esp. 2W10% as solid basis of the aid is contained in the resulting granular gypsum. The mixt. is then granulated and dried to obtain granular gypsum with enhanced hardness. This gypsum is used as a soil conditioner, a regulator for bulk blend fertilizer, etc.
