In modern granule manufacturing, the roller granulator represents the ultimate fusion of precision instrumentation and exquisite craftsmanship. This advanced fertilizer manufacturing equipment achieves unparalleled production efficiency thanks to its ingenious roller design and precise pressure control. As a specialized fertilizer compaction machine, it efficiently transforms powdered raw materials into uniform, high-density fertilizer granules through compaction and granulation, ensuring superior product quality and optimal nutrient release.
In an integrated NPK compound fertilizer production line, the roller granulator is the core component of dry granulation, working in conjunction with other equipment such as the rotary drum granulator, commonly used in wet granulation processes. While the rotary drum granulator utilizes the tumbling motion of a liquid binder to form granules, the roller granulator uses mechanical pressure to compact the fertilizer granules, making it particularly suitable for moisture-sensitive materials and producing harder, more durable granules. This complementary relationship between different granulation technologies enables manufacturers to optimize fertilizer production based on varying raw material characteristics and end-product requirements.

Precision Engineered Granulation System
The core of the roller compaction granulator lies in its modular intelligent design:
· Smart Feeding System: Equipped with 1-5m³ hoppers and variable-speed conveyors, with sensors for real-time material flow monitoring (accuracy ±0.5%)
· High-Strength Rollers: Made of chrome-molybdenum steel with surface hardness up to HRC50-60, featuring precision grooves (depth 2-10mm, spacing 5-20mm)
· Intelligent Control System: PLC cabinet with touchscreen for real-time adjustment of rotation speed (10-50rpm) and compaction force (5-30MPa)
This design enables automatic parameter adjustment based on material characteristics, ensuring consistently dense granules (density increased to 1.2-1.8g/cm³).
The Art of Fertilizer Production
From raw materials to finished fertilizer, a “precision transformation” occurs:
Material Preparation: Ingredients stored in moisture-proof silos are precisely weighed and mixed (5-15 minutes), with moisture strictly controlled at 5%-15%.
Intelligent Compaction: Mixed materials undergo a “magnificent transformation” under tremendous pressure, changing from loose powder to dense flakes with 2-3 times density increase.
Precision Post-Processing: Crusher (800-1500rpm) breaks flakes into uniform particles, while vibrating screen (8-40 mesh) selects perfect sizes, with fine powder automatically recycled (10-20% recovery).
The final polished pellets, born from advanced fertilizer granules compaction technology, boast not only a uniform and market-ready appearance but also superior physical properties. This fertilizer production machine ensures high hardness, low moisture, and excellent solubility. These premium qualities—consistent size, dust-free surfaces, and resistance to caking—provide a decisive competitive advantage, meeting the highest standards of modern agriculture.
