- Equipment upgrade and optimization
Use high-efficiency mixers like double axis mixer machines. Their unique design ensures faster, more uniform material blending, cutting mixing time and reducing energy consumption. Opt for energy-saving granulators, such as upgraded disc granulators with improved disc structures and drive systems. These maintain granule quality while lowering motor power usage.
- Production process improvement
Precise batching system: Introduce a precise batching system, use sensors and automatic control technology to accurately control the ratio of raw materials such as nitrogen (N), phosphorus (P), and potassium (K). This can avoid repeated processing caused by inaccurate batching and reduce unnecessary energy consumption.
Optimize drying process: In the drying process, use an intelligent control system to adjust the drying temperature and air volume in real time according to the humidity of the material. Avoid over-drying, make the heat utilization in the drying process more reasonable, and improve energy utilization.
- Waste heat recovery
Drying waste heat recovery: A large amount of waste heat will be generated during the fertilizer drying process, which can be collected by heat exchangers. It is used to preheat the air entering the drying equipment or for other production processes that require heat, such as preheating of raw materials, effectively reducing additional energy input.
- Automation and intelligent control
Establish an automated monitoring system for the NPK fertilizer production line to track equipment parameters (temperature, pressure, flow) and automatically adjust operations to achieve optimal energy utilization. Use smart energy management tools to analyze energy consumption patterns, identify energy waste points, and take targeted energy-saving measures.
