NPK Fertilizer Double Roller Granulator Production Line
Product Introduction:
As a professional fertilizer machinery manufacturer, we supply the turnkey NPK Fertilizer Double Roller Granulator Production Line to meet the growing global demand for high-efficiency NPK fertilizer manufacturing plants. Utilizing advanced dry granulation technology, this compound fertilizer line transforms raw chemical powders into high-density, uniform granules without adding water or chemical binders. Equipped with a heavy-duty NPK granulator machine, it is your ideal solution to lower energy costs, eliminate waste, and maximize your factory ROI.
Key Performance Features
No Drying Process Required: This non-drying NPK granulator machine system works perfectly with raw materials under 5% moisture content, saving massive amounts of coal, gas, and electricity.
High One-Time Molding Rate: The double-roller extrusion mechanism ensures a granulation rate of over 90%, directly outputting finished particles in a single pass.
Zero Waste Emission: Clean industrial production with no wastewater, no toxic gas, and an automatic dust-recycling structure that meets strict environmental standards.
Wide Material Adaptability: Specially optimized for processing heat-sensitive compounds and highly corrosive chemical powders common in complex NPK formulas.
Technical Specifications
Production Capacity: 1 - 10 Tons/Hour (Customizable based on your factory layout)
Roller Sheet Material: Heavy-duty manganese alloy or anti-corrosive stainless steel
8-Stage Step-by-Step Working Principle
The entire process flow of this high-capacity compound fertilizer line is scientifically laid out to guarantee continuous, automated, and trouble-free operation:
Smart Raw Material Batching
The automated dosing and batching system precisely weighs urea, ammonium sulfate, and potassium chloride according to your specific NPK formula ratios.
Homogeneous Material Mixing
Industrial vertical or horizontal mixers blend the dry raw materials uniformly to improve the overall nutrient balance and fertilizer consistency of the final product.
Double-Roller Extrusion Granulation
The core machine—the double roller extrusion granulator—forces the mixed dry powder through two counter-rotating rollers under high hydraulic pressure. The powder is instantly compacted into solid flakes and then broken into raw granules.
Particle Drying (Energy-Saving Option)
For formulas requiring ultra-low moisture storage, granules go through a rotary dryer. *Note: For specific dry granulation formulas, this step can be bypassed completely, acting as a true non-drying system to slash operational costs.
High-Efficiency Particle Cooling
Hot fertilizer particles from the extrusion or drying phase are cooled in a rotary cooling machine to eliminate heat-induced caking, preparing them for immediate bagging.
Precision Particle Classification & Screening
A heavy-duty rotary screening machine grades the cooled particles. Qualified products (2-4mm) move to the next stage, while oversized and undersized dust are automatically returned via belt conveyor for re-granulation, ensuring zero waste.
Finished Product Coating
Qualified fertilizer granules enter the rotary coating drum, where an anti-caking agent or oil coating is applied to increase the brightness, roundness, and shelf-life of the commercial product.
Automated Weighing & Packaging
The final film-coated particles are automatically weighed, packed into 25kg or 50kg bags, and sealed, ready for direct distribution or warehouse storage.
