Study on kinetics of water removal from products of neutralization of phosphoric acid with calcium oxide
Corn. H(3)PO(4) was neutralized with CaO to a fodder Ca phosphate and dried under static and dynamic conditions of thermal anal. at 125-165 degrees C and rise 2.5 or 5 degrees C/min. The humidity of the product decreased from 4-12% by mass down to 2-3% by mass. The drying kinetics was described by a polynomial model.
