The mixed fertilizer production line is an automated system that mixes granular fertilizers of different types and nutrients in specific proportions to produce compound fertilizers. It has the characteristics of flexible formula, simple process, and low cost, and is suitable for small and medium-sized fertilizer factories and diversified fertilizer demand scenarios.
1、 Core component equipment
Storage system
It includes multiple storage bins for storing elemental fertilizers such as nitrogen, phosphorus, potassium, and trace elements. The material of the bin is usually carbon steel sprayed with plastic or stainless steel, which is corrosion-resistant and has a long service life.
Automatic batching system
Through computer control, the raw materials are accurately measured according to the formula ratio, and a split combination installation form (such as aggregate storage hopper, belt conveyor, measuring system, etc.) is adopted to ensure a batching accuracy of ± 0.1%.
mixing device
The core equipment is a mixer, which adopts a forward and reverse spiral structure or drum design to achieve uniform mixing of materials and avoid layering.
Upgrading and conveying system
Including high angle belt elevators, high-level material silos, etc., the mixed materials are transported to the packaging process to reduce manual handling.
Packaging and palletizing system
The quantitative packaging scale realizes automatic weighing (adjustable from 5-50kg), bagging, clamping, and sealing; The robot palletizer completes the automatic stacking of finished bags, improving efficiency.
electric control system
Integrated PLC control, supporting manual and automatic mode switching, real-time monitoring of production data, ensuring process stability.
2、 Process flow
raw material preparation
Manual or mechanical input of elemental fertilizers into storage bins, and some production lines are equipped with crushers to process block shaped raw materials.
automatic batching
The system extracts raw materials from each storage bin according to the formula ratio and transports them to the mixer. The batching process is continuous and precise.
Mix well
The mixer uses spiral stirring or drum rotation to fully mix the materials and ensure consistent nutrient distribution.
finished product packaging
The mixed fertilizer is fed into the packaging scale through a hoist, which automatically completes weighing and sealing. Some production lines integrate processes such as reverse packaging, compaction, pressing, and shaping.
Palletizing and warehousing
Robots or robotic arms stack finished bags onto pallets, and forklifts transport them to warehouses, achieving full process automation.
3、 Technical features and advantages
Flexibility and Accuracy
Support mixing 2-8 types of materials, convenient formula adjustment, to meet the needs of different crops; High measurement accuracy, reducing nutrient loss (saving about 20 yuan in cost per ton).
Efficiency and Automation
Production coverage of 3-30 tons/hour, suitable for the needs of small and medium-sized factories; Ground loading design reduces the height requirements of the factory building and saves construction costs.
Reliability and Durability
The equipment is made of carbon steel or stainless steel material, suitable for harsh environments such as high altitude and humidity; Modular design is easy to maintain and has a lifespan of over 10 years.
Environmental Protection and Energy Conservation
Closed production reduces dust emissions and meets green manufacturing standards; Intelligent control optimizes energy consumption and reduces operating costs.
