Abstract
Process for the production of solid ammonium phosphate of N: P atomic ratio from 1.6 to 1.9, characterized in that it comprises adding phosphoric acid and ammonia to an aqueous suspension of ammonium phosphate, having a fluidizable consistency at the working temperature and having an N: P atomic ratio of between 1.2 and 1.8 to form more suspension substantially of equal composition and concentration and of fluidizable consistency, withdrawing an amount of said suspension substantially equivalent to that produced by the addition of phosphoric acid and ammonia, mixing the withdrawn suspension with a second liquid or suspension capable of ammonization by that, ie of lower pH, so that the ammonium phosphate of the resulting product has a predetermined N: P atomic ratio and lower than that of the aqueous suspension. of ammonium phosphate, verify that the product has a moisture content of less than 15% a wet base, so that it solidifies during said mixing and prevents its liquefaction during the subsequent ammonization, ammonise the product to a desired degree and treat it above room temperature, under conditions such that an forward transport and agitation that involves repeated exposure of fresh surfaces of that and for a period of time sufficient for the product to be solid, at room temperature.
