Method for industrially producing granulated fertilizer

The invention relates to a method for the industrial production of a granulated fertilizer, comprising the steps of granulation, drying, temperature control, screening and the like, in which the granulation step is carried out using as the starting material a homogeneous mixture in the form of a thick aqueous suspension consisting of water-soluble components and insoluble components, before the granulation step, the method also includes pre-mixing the starting material with other feedstocks selected from the group consisting of high nitrogen content products, high phosphorus content products, high potassium content products, high sulfur content products, high calcium content products, organic materials, trace elements, and compositions thereof. 本发明提供了一种用于工业生产颗粒肥料的方法，该方法包括造粒、干燥、调温和筛分等步骤，其中造粒步骤使用由水溶性成分和不可溶成分组成的呈浓稠水悬浮液的均质混合物作为起始物料进行，在造粒步骤之前，该方法还包括将该起始物料与选自高氮含量产物、高磷含量产物、高钾含量产物、高硫含量产物、高钙含量产物、有机材料、微量元素以及它们的组合物的其他原料进行预混合。
