摘要

Granular fertilizer solids comprising ammonium phosphate, advantageously particulate NP/NPK fertilizers, are prepared by (i) granulating a liquid/dry solids admixture of fertilizer values in a granulation zone, (ii) next transferring said admixture to, and drying same, in a drying zone, (iii) while simultaneously injecting into said drying zone a jet spray of a slurry of ammonia neutralized acid values discharged from a pipe reactor, such that (iv) said jet spray directly impinges upon drying particles of wet solids transferred from said granulation zone, and whereby (v) dried final product simultaneously results therefrom, and (vi) then recovering a fraction of said dried final product, while (vii) recycling another fraction thereof, as dry solids, to said granulation zone.
