manufacturing process of triple superphosphate fertilizer granules based on enriched with sulfur

摘要

the invention relates to a production process of phosphate fertilizer granules based on triple enriched with sulfur.the elemental sulfur in the solid, finely divided, is incorporated in the granules of triple superphosphate.the method is characterised by the fact that the elementary sulfur and phosphate ore are mixed prior to fresh, to form a homogeneous mixture.and introduced into the reactor via a pru00c9mu00c9langeur.in the last place the mixture in the wet sulphur and phosphate from phosphoric acid attack or the slurry resulting from the attack, or both.in addition to good physical and chemical quality.the granules manufactured according to this process enrais file distribution homogeneous particles of sulfur granules with conservation of the initial block of sulphur is used.
