1.Select the appropriate granulation equipment.
Fertilizer granulation machines are the core equipment in the fertilizer production line, and different types of granulation machines are suitable for different processes.
• Double roller extrusion granulation machine: It adopts dry granulation process, does not require drying, has low energy consumption, and is suitable for NPK compound fertilizer production.
• Drum granulation machine and disc granulator machine: They are suitable for large-scale production, but need to be equipped with a drying system and have higher energy consumption. Enterprises should choose the appropriate granulation equipment according to their production needs to improve production efficiency and reduce energy consumption.
2. Optimize the fertilizer production line and enhance the level of automation.
The rational configuration of the fertilizer production line directly affects production efficiency.
• The adoption of an automatic batching system enhances the accuracy of raw material proportioning and reduces waste.
• The selection of efficient conveying equipment, such as belt conveyors, improves the efficiency of material transportation.
• Through a PLC intelligent control system, automated operation is achieved, reducing manual intervention and enhancing production stability.
3. Improve raw material processing to enhance product quality
• The degree of material crushing affects the granulation effect. High-efficiency crushers should be used to ensure uniform fineness of the materials.
• Control the moisture content of the materials to maintain an appropriate humidity level, thereby increasing the success rate of granulation.
• Utilize screening equipment to recover substandard granules, reduce waste, and improve the yield of finished products.
4. Enhance energy utilization rate and reduce production costs
• Adopt energy-saving drying equipment, such as rotary drum dryers, to improve the utilization rate of thermal energy.
• In the NPK fertilizer production line, the waste heat from exhaust gas can be utilized for drying to reduce energy consumption.
• Use variable frequency motors to control equipment operation, lowering energy consumption and extending the service life of the equipment.
5. Maintain equipment to ensure stable production
• Regularly inspect equipment such as fertilizer granulators, crushers, and mixers to prevent wear from affecting production efficiency.
• Key components like bearings and gears should be lubricated regularly to reduce mechanical wear and tear.
• If any abnormalities occur during equipment operation, they should be promptly repaired to prevent minor issues from escalating into major malfunctions that could disrupt production schedules.
