In modern agricultural production, fertilizer is a crucial input for ensuring high and stable crop yields. With the expansion of agricultural scale and mechanization, traditional powdered fertilizers are gradually being replaced by granular fertilizers. Fertilizer production machine—particularly core equipment like granulators—have become crucial for improving fertilizer quality and production efficiency.
Main Types of Fertilizer Granulators
Disc Granulator: These use rotating, tilted discs to roll and agglomerate fertilizer powder, forming uniform granules. They are suitable for small- and medium-sized organic fertilizer or compound fertilizer production.
Rotary drum Granulator: These utilize a rotary drum combined with steam/binder granulation. They are suitable for large-scale compound fertilizer production, offering high granulation rates and strong granules.
Double roller press Granulator: These use mechanical high-pressure compression to directly form granules, eliminating the need for drying. These are energy-efficient and highly efficient, but the granules dissolve more slowly, making them suitable for specialty fertilizers.
Supporting Fertilizer Equipment
Fertilizer Crusher: Pre-treats raw materials to ensure fertilizer powder fineness and improve granulation efficiency.
Fertilizer Mixer: Evenly mixes nutrients such as nitrogen, phosphorus, and potassium to ensure precise fertilizer ratios.
Fertilizer Dryer and Cooler: Reduce granule moisture and improve storage stability.
Fertilizer Screener and Coating Machine: Remove unqualified granules and coat them with a slow-release film to extend fertilizer effectiveness.
Advantages of Fertilizer Granulation Production
Improved Fertilizer Efficiency: Granular fertilizers offer a slow-release effect, reducing nutrient loss and increasing nutrient utilization by 20%-30% compared to powdered fertilizers.
Reduced Pollution: Granules are less likely to create dust, reducing environmental pollution during transportation and use.
Suitable for Mechanization: Uniform granules facilitate mechanized fertilization, making them suitable for modern large-scale farms.
High Product Added Value: Granular fertilizers are easier to package, store, and sell, leading to greater market acceptance.
Fertilizer production machinery, particularly fertilizer granulation technology, is driving the fertilizer industry towards high efficiency, greenness, and intelligence.
