Abstract

PURPOSE: To enhance the granular form, hardness and regular fluidity of granular potassium sulfate by swelling a mixture of potassium sulfate, acidic potassium sulfate and a calcium compound, with water, which forms gypsum by reaction with acidic potassium sulfate and granulating the swollen mixture by forced mixing under shear.
CONSTITUTION: To potassium sulfate are added acidic potassium sulfate by 6W 25wt% to the amount of the sulfate and slaked lime or quick lime which forms gypsum by reaction with acidic potassium sulfate by neutralization equiv. to the acidic potasium sulfate or a slight excess over the equiv., and they are mixed. This mixture is then swollen with 10'21wt% water. To the water may be added a water soluble binder such as starch or lignin by 2.5W20pts.wt. to 100pts.wt. of water. the swollen mixture is charged into a container fixing system mixer of puddle type or ribbon type and granulated by mixing under shear at 30W450m/min peripheral speed of agitating blades.
