In traditional organic fertilizer production, the granulation process often involves a series of complex steps, including raw material drying, crushing, mixing, and re-drying. This process not only requires significant equipment investment and high energy consumption but also presents numerous challenges such as dust pollution and nutrient loss. Zhengzhou Huaqiang Heavy Industry, directly addressing these industry pain points, has successfully developed the DZJ type double roller extrusion granulator through continuous technological innovation. This machine completely revolutionizes the traditional production model with its drying-free, ambient temperature granulation process, leading organic fertilizer granulation technology into a new era of high efficiency and energy saving.
Technological Innovation: Ambient Temperature Granulation, One-Step Forming
The core breakthrough of the double roller extrusion granulator lies in achieving "ambient temperature granulation and one-step forming." This equipment utilizes a special double roller extrusion principle, directly compressing raw materials with suitable moisture content into dense granules under high pressure without pre-drying. This innovative process brings multiple revolutionary advantages:
Significantly reduced energy consumption: Eliminating the drying step in the traditional process directly saves more than 40% of heat energy consumption;
Simplified process flow: Achieving "one-stop" forming from raw materials to finished products, reducing equipment footprint by approximately 30%;
Effective nutrient retention: Avoiding the damage to organic matter and active ingredients caused by high temperatures, improving fertilizer quality;
Significant environmental benefits: The fully enclosed production process virtually eliminates dust emissions, achieving clean production.
Excellent Performance: High Efficiency, Stability, and Wide Application
Huaqiang Heavy Industry's DZJ type double roller extrusion granulator is available in two specifications: 1-1.5 tons/hour and 1.5-3 tons/hour, meeting the production needs of different scales. The equipment excels in multiple key performance indicators:
Breakthrough improvement in granulation rate: Through optimized roller surface design and pressure control system, the granulation rate is stably maintained at over 95%, far exceeding the industry average;
Highly integrated structure: Integrating granulation, molding, and screening functions, it offers simple operation and low maintenance costs;
Reinforced key components: The roller body uses special wear-resistant alloy materials, extending its service life to more than twice that of traditional equipment;
Strong raw material adaptability: Suitable not only for organic fertilizer production but also widely applicable to powder granulation in various fields such as compound fertilizers, chemicals, pharmaceuticals, and feed.
Global verification: Successful practice in the Nigerian project
In a large-scale organic fertilizer project in Nigeria, Huaqiang Heavy Industry's DZJ double-roller extrusion granulator demonstrated exceptional adaptability. Facing the local high-temperature and high-humidity climate conditions and diverse agricultural waste raw materials, the equipment operated continuously and stably for over 6000 hours, achieving the following significant results:
Maximized raw material utilization: 100% conversion of abundant local resources such as palm waste and livestock manure into standardized granular fertilizers;
Zero emissions throughout the production process: The closed production process completely eliminates dust and wastewater pollution;
Outstanding economic benefits: Compared with traditional processes, production costs are reduced by approximately 35%, and the investment payback period is shortened to 12 months;
Excellent product quality: The produced granular fertilizer has high strength and controllable solubility, and is highly welcomed by local farmers.
Technological extension: Deep integration of intelligence and environmental protection
Huaqiang Heavy Industry has incorporated several intelligent innovations into the double-roller extrusion granulator:
Pressure self-adaptive system: Automatically adjusts the extrusion pressure according to raw material characteristics to ensure stable granulation quality;
Remote monitoring platform: Supports real-time collection and analysis of equipment operating data, enabling preventive maintenance;
Intelligent energy consumption optimization: Dynamically adjusts equipment operating parameters through algorithms to further reduce energy consumption.
These technological innovations make this equipment not only a granulation machine but also an intelligent production unit.

Industry benchmark: Leading a new direction in green manufacturing
The successful development and application of Huaqiang Heavy Industry's double-roller extrusion granulator has set a new technological benchmark for the organic fertilizer industry and the entire powder granulation field. Its "zero raw material waste, zero production emissions" concept perfectly aligns with the global trend of circular economy and green manufacturing. To date, this model of equipment has been exported to more than 20 countries and regions in Southeast Asia, Africa, and South America, providing efficient granulation solutions to over 500 customers worldwide. Against the backdrop of China's "dual carbon" strategy and global sustainable development, this low-energy consumption, high-efficiency, and environmentally friendly granulation technology is bound to gain wider application.
Zhengzhou Huaqiang Heavy Industry will continue to deeply cultivate the field of ambient temperature granulation technology, driving equipment upgrades through continuous innovation, and providing global customers with greener, smarter, and more efficient granulation solutions to contribute to the realization of circular agriculture and sustainable development goals. The roller extrusion granulator is not only a product innovation but also a vivid embodiment of Huaqiang Heavy Industry's philosophy of "technology empowering industry and innovation driving the future."
The DZJ granulator represents the leading edge of dry fertilizer compaction technology, which can be integrated into broader fertilizer production schemes. This type of double roller press granulator, or fertilizer compactor, is the core of a roller press granulator production line and is a highly efficient fertilizer compaction machine. It achieves fertilizer granules compaction through high mechanical pressure without heat or binders, making it ideal for certain stages of the npk fertilizer manufacturing process, particularly for moisture-sensitive materials or when producing high-density compound fertilizer flakes. This dry method offers an alternative to the traditional wet agglomeration processes typically associated with a rotary drum granulator. Within the complete npk manufacturing process, the roller press line can be used independently or in combination with other granulation methods to create a versatile and energy-efficient production system, perfectly aligning with modern goals of reducing thermal energy consumption and process complexity.
