Application Guide of Rotary Drum Granulator in Fertilizer Production

The rotary drum granulator is a core equipment in modern fertilizer production, particularly suitable for the following types of fertilizer granulation:

• NPK Compound Fertilizer - In the npk fertilizer production process, the rotary drum granulator can uniformly mix nitrogen, phosphorus, potassium and other nutrient elements to form regular granules
• Organic Fertilizer - Suitable for organic fertilizer manufacturing process, capable of processing various organic materials
• Biofertilizer - Among the equipments required for biofertilizer production, the rotary drum granulator is a key forming equipment

Granulation Technology Comparison and Scale Adaptability

Compared to fertilizer granules compaction technology using fertilizer compaction machine, rotary drum granulator is more suitable for medium to large scale fertilizer processing plants. Its main advantages include:

• Large processing capacity, suitable for continuous production
• High granule uniformity, stable product quality
• Adaptable to various raw material formulations, good flexibility
• Relatively low operating costs, suitable for scale production

Key Points for Granulator Selection in Different Fertilizer Types

Organic Fertilizer Production

In organic fertilizer manufacturing process, granulator selection should consider:

• Equipment corrosion resistance - organic materials are usually corrosive
• Viscosity handling capacity - organic raw materials often have high viscosity
• Temperature control - avoid high temperature damaging organic components

NPK Compound Fertilizer Production

In the complete npk manufacturing process, drum granulator selection should consider:

• Mixing uniformity - ensure even distribution of nutrient elements
• Granule strength - meet transportation and storage requirements
• Moisture control - affects granule formation and quality

Biofertilizer Production

When planning equipments required for biofertilizer production, attention should be paid to:

• Temperature sensitivity - protect active microorganisms
• Hygiene standards - prevent contamination by miscellaneous bacteria
• Compatibility with special additives

Choosing appropriate granulation technology and equipment is crucial for fertilizer production. With its excellent performance and adaptability, rotary drum granulator has become the preferred equipment for modern fertilizer production. Manufacturers should select the most suitable granulation solution based on product type, production scale and process requirements.
