Rotary drum Granulator: A Powerful Aid for Fertilizer Production?

In modern agricultural fertilizer production, the rotary drum granulator is undeniably a core piece of equipment! Like a skilled craftsman, it expertly transforms common fertilizer raw materials like urea and diammonium phosphate, as well as mixed raw materials for bio-organic fertilizers, into granular products. The entire process utilizes low-temperature granulation technology, which is not only efficient and stable, but also precisely controls particle diameters between 2 and 5 mm and hardness between 3 and 5 Newtons, meeting the fertilization needs of various crops while also keeping raw material waste below 5%.This allows every bit of fertilizer raw material to fully function, while also preventing high temperatures from damaging the nutrients in the raw materials. This greatly facilitates subsequent fertilizer storage, transportation, and field application. Granular fertilizers are less likely to clump, and can be evenly spread during mechanized fertilization. Of course, the production of high-quality fertilizers requires the coordinated cooperation of other fertilizer equipment. The raw material crusher acts like a pair of sharp scissors, first crushing bulk phosphate rock powder, potash fertilizer crystals, and other raw materials into a uniform powder with a fineness of 80-100 mesh, laying a solid foundation for the smooth granulation of the rotary granulator. The mixer acts like a flexible "seasoner," blending nitrogen, phosphorus, potassium, and trace elements at high speed according to a preset formula to ensure that each fertilizer grain has a balanced nutritional composition. After granulation is complete, the drying equipment acts like a warm bellows, reducing the moisture content of the grains to below 10%. To prevent mold and mildew, the rotary screener machine acts as a rigorous "quality inspector," filtering out overly coarse or fine particles for reprocessing, ensuring consistent quality in the final fertilizer product. With the seamless integration of these advanced devices, the fertilizer production line's daily production capacity can be increased by over 30%, while producing fertilizer of consistent and reliable quality. Whether in open-field agriculture for growing wheat and corn or in protected agriculture for cultivating vegetables and fruits, the customized fertilizers produced by these devices precisely match crop needs.
