NPK Roller Extrusion Fertilizer Production Line Anti Caking Coating Machine Automatic Weighing Bagging System
NPK Roller Extrusion Production Line with Coating and Packaging System
This NPK Fertilizer Production Line integrates a rotary coating machine and automatic weighing bagging system to enhance finished product quality and packaging efficiency. The anti-caking coating prevents moisture absorption and granule degradation during storage and transport.
Coating and Packaging Features
- Rotary Drum Coating Machine: Continuous coating system applies anti-caking agent powder or liquid coating evenly onto granule surfaces via spray nozzles inside a rotating drum, treatment capacity matching production line output
- Anti-Caking Protection: Proprietary coating formulation prevents moisture absorption and caking during bulk storage for 6-12 months, maintaining free-flowing granule properties for mechanical fertilizer spreaders
- Color Coating Option: Optional color coating system adds distinctive color identification to your fertilizer brand, enhancing market recognition and preventing product counterfeiting
- Automatic Weighing System: Electronic dual-scale weighing system with ±0.2% accuracy, automatically filling 25kg or 50kg bags with real-time weight display and data logging
- Bagging and Sealing: Automatic bag clamping, filling, weighing, and release cycle at 4-6 bags per minute; integrated heat sealing for PE inner-liner bags or sewing machine for woven PP outer bags
- Conveyor to Warehouse: Finished bags transported via belt conveyor with automatic inkjet date coding and optional robotic palletizing system for warehouse-ready output
