What equipment is included in a complete organic fertilizer production process?

A complete organic fertilizer production line is equipped with specialized machinery for four major stages: fermentation pre-treatment, material refinement, granulation/forming, and finished product processing. It enables fully automated, standardized production and accommodates various organic raw materials—such as livestock manure, crop straw, and kitchen waste—to produce both powdered and granular organic fertilizers. The system features a well-defined division of labor with seamlessly integrated stages.

Fermentation pre-treatment serves as the core foundation of organic fertilizer production, with the large-wheel compost turner acting as the primary piece of equipment. After raw materials are proportioned and piled, the compost turner continuously aerates the material, replenishing oxygen while dissipating heat and moisture. This accelerates microbial decomposition, effectively eliminates odors and harmful pathogens, and prevents the "root-burning" issues often caused by raw materials. It is crucial for ensuring the fertilizer is fully decomposed and meets quality standards; when paired with a conveyor system, it enables automatic feeding and reduces labor requirements.
The material refinement stage focuses on optimizing the material's condition and primarily involves half-wet material crushers, drum screeners, and mixers. Fermented material often contains clumps and impurities; crushers thoroughly break down moist, agglomerated material to reduce particle size, while screeners remove impurities (such as stones and plastic) and oversized particles to ensure uniformity. Mixers blend primary materials, additives, and functional microbial agents in precise proportions to ensure a balanced nutrient profile, laying a solid foundation for the subsequent granulation process.
Granulation is the core process in the production of granular organic fertilizer, with the new type organic fertilizer granulator serving as the primary equipment. Optimized to handle the high organic matter content and significant viscosity fluctuations characteristic of organic fertilizers, this machine offers superior adaptability to raw materials; it can granulate fermented manure, crop stalks, and similar materials without the need for additional binders, achieving a high granulation rate and producing granules with optimal structural strength. Compared to traditional models, this new granulator offers lower energy consumption and simplified maintenance, and models can be flexibly selected to meet specific production capacity requirements.
The finished product processing stage determines storage stability and application effectiveness, utilizing supporting equipment such as dryers, coolers, screeners, coating machines, and automatic packaging machines. Drying and cooling equipment reduces granule moisture content, increases hardness, and prevents caking; a secondary screening process removes substandard granules; a coating machine applies anti-caking agents and antimicrobial agents to extend the fertilizer's shelf life; and finally, an automatic packaging machine handles precise weighing, sealing, and bagging to produce the finished organic fertilizer.
This complete organic fertilizer production line accommodates varying capacity requirements—ranging from small to large scales—and integrates operations from raw material fermentation to the dispatch of finished products. It significantly boosts production efficiency and ensures consistent product quality, serving as the standard configuration for large-scale organic fertilizer production.
