This fertilizer roller press granulator production line utilizes a dry extrusion molding process, eliminating the need for water addition and drying. Its wide range of applications allows it to be adapted to the production of various fertilizer types, catering to different plant sizes and raw material types.

Regarding fertilizer types, this production line primarily produces organic fertilizers and organic-inorganic compound fertilizers. It can also produce pure nitrogen-phosphorus-potassium compound fertilizers, bio-fertilizers, humic acid fertilizers, and micronutrient fertilizers. It is particularly suitable for heat-sensitive materials, operating at ambient temperature throughout the process. This effectively protects the microorganisms, organic matter, and active ingredients, preventing high-temperature degradation—an advantage not found in traditional wet granulation equipment.

In terms of raw material compatibility, it can process well-rotted organic raw materials such as livestock and poultry manure, straw, mushroom residue, and distiller's grains. It can also be used with granular and powdered fertilizers such as urea, potassium chloride, and monoammonium phosphate. It can process dry powder, loose materials, and slightly agglomerated materials normally, requiring only a moisture content control of 5%–8% for production.

In terms of production scale and site requirements, fertilizer production machines feature a flexible modular design. Small, simple lines are suitable for township processing plants, planting bases, and small to medium-sized farms for producing fertilizers for self-use and regional retail. Fully automated production lines can meet the large-scale mass production needs of medium and large-sized fertilizer enterprises, supporting continuous operation and adapting to bulk export orders.

Furthermore, this process is also suitable for deep processing of fertilizers and waste recycling. Fine powder and scraps generated during granulation can be recycled and re-granulated, resulting in high raw material utilization. The overall equipment has a moderate footprint and is easy to operate and maintain, making it suitable for both new fertilizer projects and the renovation of old production lines. It is a mainstream granulation solution that balances versatility and economy.
