Double Roller Extrusion Dry Granulation NPK Compound Fertilizer Production Line without Drying Process
Double Roller Extrusion NPK Compound Fertilizer Production Line
This Double Roller Extrusion Granulation Production Line utilizes dry compaction technology that eliminates the energy-intensive drying process entirely. Raw material powders are compressed between two counter-rotating rollers into dense sheets, then crushed and screened to produce uniform compound fertilizer granules.
Roller Extrusion Advantages
Zero Drying Required: Unlike rotary drum steam granulation that requires 5-8% moisture and subsequent drying, roller extrusion processes materials at their natural moisture content (2-5%), saving significant fuel and investment costs
Cold Press Technology: No heating or chemical reactions involved, making it ideal for heat-sensitive raw materials such as ammonium nitrate, urea, and organic-inorganic compound formulations
Lower Investment Cost: Eliminates the need for dryer, hot air furnace, and associated dust collection systems, reducing total equipment investment by 30-40% compared to wet granulation lines
Compact Footprint: Simplified process flow (batching → mixing → extrusion → crushing → screening → packaging) requires 40% less factory floor space than wet granulation lines
Instant Production: No preheating or startup time required, achieving full production within minutes of startup; ideal for multi-formula small-batch production
Versatile Output: Produces irregular pillow-shaped granules (2-5mm) preferred in certain markets for their slow-release characteristics and mechanical spreading compatibility
