The application of rotary drum granulator in agriculture is mainly concentrated in the field of fertilizer production, and its specific applications include:
NPK fertilizer production:
NPK fertilizer is a widely used compound fertilizer in agriculture, which contains the three main nutrients required for plant growth: nitrogen (N), phosphorus (P), and potassium (K). The rotary drum granulator can evenly mix and granulate NPK raw materials, producing granular fertilizers with uniform particle size, moderate hardness, and good flowability, which are easy to store, transport, and use, and also improve the efficiency of fertilizer use.
Organic fertilizer production:
Organic fertilizers are usually made from organic materials such as animal and plant residues, livestock and poultry manure, and urban organic waste. The rotary drum granulator can process and granulate these organic raw materials appropriately to produce granular fertilizers rich in organic matter, which helps improve soil structure and enhance soil fertility.
Microbial fertilizer production:
Microbial fertilizers refer to fertilizers containing specific beneficial microorganisms that can improve soil environment and promote plant growth. The rotary drum granulator can mix microorganisms with carrier materials and granulate them in the production of microbial fertilizers, ensuring the activity and stability of microorganisms during storage and use.
Production of slow-release fertilizers:
Slow release fertilizers can continuously release nutrients over a long period of time, avoiding waste and environmental pollution caused by excessive release of nutrients at once. The rotary drum granulator can add slow-release materials during the production process to form granular fertilizers with slow-release properties through granulation.
Production of specialized fertilizers:
The rotary drum granulator can also be used to produce specialized fertilizers for specific crops or soil conditions, such as rice specific fertilizers, fruit tree specific fertilizers, etc. By adjusting the raw material ratio and granulation parameters, granular fertilizers that meet specific needs can be produced.
Production of soil amendments:
In addition to fertilizers, rotary drum granulators can also be used to produce soil amendments, such as particles containing humic acid, to improve soil structure, enhance soil water retention and permeability.
The application of rotary drum granulator in agriculture not only improves the production efficiency and quality of fertilizers, but also promotes sustainable development of agriculture. By improving the efficiency of fertilizer use, it reduces the negative impact on the environment and meets the needs of modern agriculture for efficient and precise fertilization.
