5t/H Compound Magnetic NPK Fertilizer Production Line For Chemical Powder
Chemical Dry Powder Double Roller Extrusion Granulator NPK Fertilizer Production Line
NPK fertilizer production line can produce various concentrations and types of compound fertilizers, including organic fertilizers, inorganic fertilizers, biological fertilizers, and magnetic fertilizers. This system is particularly effective for producing rare earths, potash, and ammonium bicarbonate series compound fertilizer granulation, filling technological gaps and achieving advanced levels in China.
Working Principle
This roller granulation system operates on an extrusion sliding model. The working principle involves: electric motor driving belts and pulleys, transmission to the drive shaft via reducer, and synchronized operation through open gears and passive shafts. Materials are fed from the hopper, extruded by rollers, and demolded to form granules.
Key Advantages
- Lower investment with excellent economic returns
- Compact, scientifically designed system with advanced technology
- No waste discharge, stable operation, easy maintenance
- Direct dry powder extrusion with continuous production capability
Production Processes
1. Mixing Process
Mix required chemicals including NPK, NP, ANP, DAP, MAP, CAN, SSP, ASO4, MOP, SOP, MAP, and CaCo3
2. Smashing Process
After fermentation, lumpy materials are crushed using high-moisture material crushers for efficient processing of semi-wet materials
3. Granulation Process
Critical production stage where nutrients are added and spherical particles are formed using specialized organic fertilizer granulators
4. Drying Process
Granules are dried using rotary tumble dryers to reduce moisture content to 10%-40%
5. Cooling Process
Dried particles are cooled using drum coolers to ensure product quality
6. Screening Process
Drum-type fertilizer screeners separate waste products from standard materials
7. Packaging Process
Fertilizer packaging machines automatically and efficiently pack finished products
