Fully Automatic Ball Shape Compound Fertilizer Production Line with 15T/H Capacity

This fully automatic compound fertilizer production line includes comprehensive equipment for complete fertilizer manufacturing: automatic batching machine, grinder, mixer, drum granulator, dryer, LQ series cooler, screening machine, automatic packaging machine, coating machine, and automatic weighing machine.

1. Raw Material Ingredients: Urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate, potassium chloride and other raw materials are proportioned according to market demand and soil testing results.
2. Raw Material Mixing: Prepared raw materials are stirred evenly to increase uniform fertilizer efficiency content.
3. Raw Material Granulation: Mixed materials are fed into granulator (rotary or extrusion type) for particle formation.
4. Granule Drying: Granules are sent to dryer to reduce moisture content, increasing strength for storage.
5. Granule Cooling: Dried granules are cooled to prevent agglomeration and facilitate storage/transport.
6. Particle Classification: Cooled particles are screened;不合格 particles are crushed and re-granulated.
7. Finished Coating: Qualified products are coated to enhance brightness and roundness.
8. Finished Product Packaging: Coated particles are packaged as finished products and stored in ventilated areas.

Compound fertilizer contains two or all three basic plant nutrients (Nitrogen, Phosphorus, Potassium) plus microelements (B, Mn, Cu, Zn, Mo). Raw materials can be powder or bulk:

The compound fertilizer production line typically includes 9 processes: batching, grinding, mixing, granulating, drying, cooling, screening, coating and packaging. Batching, mixing, granulating, drying, and screening are essential processes, while others are optional based on production capacity.
