PRODUCTION OF SOLID CHEMICAL PRODUCT

Method for solidifying a chemical product (10) which is in melt form, comprising the following steps: subjecting a first stream (10a) of said chemical product to a prilling stage, with production of prills (12) of varying diameter; feeding said prills (12) to a screening device, which separates them according to their diameter into at least a first fraction (13) and a second fraction (14), the average diameter of the prills of said first fraction (13) being smaller than the average diameter of the prills of said second fraction (14); subjecting a second stream (10b) of said chemical product and the first fraction (13) of prills to a granulation stage, with the production of granules (16). 熔体形式化学产品(10)的固化方法，包括以下步骤：使所述化学产品的第一料流(10a)经历造粒阶段，产生不同直径的造粒产品(12)；将所述造粒产品(12)送入筛选装置，该筛选装置根据它们的直径将它们分成至少第一部分(13)和第二部分(14)，所述第一部分(13)的造粒产品的平均直径小于所述第二部分(14)的造粒产品的平均直径；使所述化学产品的第二料流(10b)和第一部分(13)的造粒产品经历制粒阶段，产生制粒产品(16)。
