Double Roller press granulator are core equipment in the field of fertilizer granulation.  They utilize a drying-free, high-pressure extrusion process, enabling the formation of granular materials from powdered raw materials without the need for additional binders.  With advantages such as high granulation rate, low energy consumption, and good particle strength, they are widely applicable to the production and processing of various types of fertilizers.

Firstly, this fertilizer making machine can efficiently produce compound fertilizers (NPK).  Whether using single-element fertilizers of nitrogen, phosphorus, and potassium as raw materials, or formulations with added trace elements, the high-pressure roller press granualtor produciton line can directly form the fertilizer into granules. This allows for flexible adjustment of production to create general-purpose, high-concentration, or crop-specific compound fertilizers. The finished granules have a uniform nutrient distribution and are less prone to pulverization during storage, transportation, and application, meeting the fertilization needs of large-scale farming.Secondly, roller extrusion granulation machines are also an ideal choice for organic fertilizer production. For organic raw materials such as composted livestock and poultry manure, straw, mushroom residue, and medicinal residue, only a small amount of conditioning agent is needed to adjust the moisture content and carbon-nitrogen ratio before extrusion into granular organic fertilizer.  It can also process organic-inorganic compound fertilizers, granulating organic and chemical fertilizer raw materials in proportion, combining the soil-improving advantages of organic fertilizers with the quick-acting characteristics of chemical fertilizers.

In addition, the equipment can directly process single fertilizers, including common single fertilizers such as urea, ammonium chloride, potassium sulfate, and potassium chloride, converting powdered raw materials into granular form, improving the fluidity and utilization rate of the fertilizer, and reducing dust loss during fertilization.

Finally, it also performs outstandingly in the production of functional fertilizers, producing special fertilizers containing humic acid, amino acids, and biological agents to meet the needs of fruits, vegetables, and cash crops for high-quality fertilizers, helping to improve crop yield and quality.
