In the context of modern sustainable agriculture, new organic fertilizer granulators and dual-function granulators are becoming core equipment in bio-fertilizer production lines. These innovative technologies not only improve fertilizer production efficiency but also significantly enhance the physical characteristics of organic fertilizers, providing strong support for organic farming.
In the “organic fertilizer production process“, granulators serve as the key equipment for shaping powdered materials into uniform pellets, typically positioned after fermentation and before packaging. Within a complete “fertilizer production line“, they connect pretreatment and post-processing stages, transforming raw organic matter into market-ready granular fertilizer with improved physical properties and handling characteristics.
The Revolutionary Role of Granulators
New type organic fertilizer granulators transform powdered organic materials into uniform granules through mechanical pressure, solving the problems of loose texture and difficult application associated with traditional organic fertilizers. The dual-function granulators go further by integrating mixing and granulating functions into one unit, greatly simplifying the production process while reducing energy consumption and space requirements.
The greatest advantage of dual-function granulators lies in their efficiency—they can complete two critical steps (material mixing and granulation) in a single device, reducing material loss during transfer while ensuring product consistency.
Material Characteristics and Product Quality
These granulators can handle raw materials with a relatively wide moisture content range, typically between 20%-40%. Raw materials may include various organic wastes such as livestock manure, crop straw, and food processing residues. The final granules exhibit these notable characteristics:
- Uniform particle size, typically 2-6mm in diameter
- High mechanical strength, resistant to breakage during transportation
- Controllable dissolution rate to meet different crops’ nutrient requirements
- Smooth surface with good flowability for mechanized application
Integration with Fertilizer Production Lines
In a complete “fertilizer production line,” granulators are typically positioned after fermentation and drying processes, serving as the key step in forming the final product. For “equipments required for biofertilizer production,” besides granulators, supporting equipment such as fermentation tanks, crushers, mixers, dryers, and packaging machines are also needed.
The emergence of new granulators has made biofertilizer production lines more compact and efficient, especially suitable for small and medium-sized organic fertilizer plants. They not only lower the investment threshold but also improve product quality consistency, making large-scale commercial production of organic fertilizers possible.
