With the continuous improvement of the level of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, and the vigorous development of economic crops, flowers and urban greening. The growth of crops and the ecological balance of nutrients in the soil are becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious. Sulfur-coated urea fertilizer has become a popular fertilizer product on the market. It is coated with a layer of sulfur and other trace elements on the outside of the urea through a coating machine, powdering machine, etc., so that the fertilizer nutrients are slowly released. It is different from the compound fertilizer rotary drum granulator processing technology. Why to use sulphur coated urea fertilizer 1. Sulfur-coated urea can improve the fertilizer utilization rate, which is similar to the granular fertilizer made by the disc granulator , and c...

Mixing granulation of different NPK fertilizers is the core of compound fertilizer processing. Fertilizer production line generally uses the following methods to granulate: 1. Extrusion granulation is a method of making dry powder or wet powder containing binder into cylindrical, spherical or sheet shape by mechanical processing such as extrusion, roller extrusion or pressing. The technology of dry granulation is used in the flat die pellet mill, the ring die pelleting machine and the double roller extrusion granulator. 2. Agglomerating granulation, which is under the action of rotation, vibration, agitation and so on, makes the wet powder in motion agglomerate. Or use the fluidized bed to make the material obtain the cohesive force by supplying the spray liquid binder) so as to grow into the appropriate particles. This method is used in disc granulator and roatry drum granulator. 3. Crushing granulation, which is to crush the block material into particles of appropriate size. ...
