The rotary drum granulator is a core piece of equipment for producing compound fertilizers, organic fertilizers, and NPK fertilizers. It transforms powdered raw materials into uniform granules through physical tumbling and chemical binding.

1.Raw Material Preparation
Powdered raw materials are crushed and screened to ensure uniform particle size. This improves granulation efficiency and granule strength. Nutrient ratios (nitrogen, phosphorus, potassium, etc.) are adjusted according to the formula to ensure balanced nutrition in the final product.
2.Mixing and Moistening
Materials enter the rotary drum granulator, where liquid (water, steam, or a binder) is sprayed in. This moistens the material surface, promoting granule formation. Liquid spraying must be precisely controlled—too much causes over-wetting and clumping, while too little reduces granulation rates.
3.Tumbling and Granule Formation
The drum rotates at a suitable speed (typically 10-20 rpm). Material rolls and agglomerates under centrifugal force and friction, forming initial granules. Internal baffles may be installed to improve mixing and granule uniformity.
4.Drying and Screening
Newly formed granules move to a dryer to remove excess moisture, improving hardness and storage stability. After vibrating screening, qualified granules proceed to coating or packaging. Fine powder is recycled back to the granulator, reducing waste.

Factors Affecting Granulation Efficiency
1.Drum Rotation Speed: Low speed slows granule formation; high speed risks breaking granules.
2.Liquid Spray Method: Atomized spray ensures even distribution and higher granulation rates.
3.Raw Material Ratio: Proper nutrient balance and binder selection impact granule strength and solubility.
4.Temperature Control: Moderate heating speeds up moisture removal and drying efficiency.

By adjusting parameters like rotation speed, liquid spray volume, and material ratios, the rotary drum granulator process can be optimized to produce uniform, strong granules with excellent slow-release properties.

In modern agricultural production, efficient and high-quality fertilizers are key to ensuring bountiful crop harvests. The NPK fertilizer manufacturing process is the core technology that transforms various raw materials into effective compound fertilizers. This process is not only scientifically precise but also an art form. Let’s explore the secrets behind this remarkable transformation.

Precision Preparation: The Foundation of Quality Fertilizer

The first step in the NPK manufacturing process involves meticulous screening and pretreatment of base fertilizers. Each raw material is individually screened to ensure uniform particle size, then crushed to prepare for subsequent mixing. After screening, qualified materials are fed into corresponding hoppers. This step may seem simple but plays a decisive role in the quality of the final product.

Precise measurement is crucial for producing high-quality NPK fertilizers. According to formula requirements, each base fertilizer is accurately fed from its respective hopper into the feeding hopper through precision metering equipment, conveying equipment, and lifting equipment. Meanwhile, recycled materials also enter the feeding hopper together with the base fertilizers through lifting devices, achieving resource recycling.

Granulation Process: The Transformation From Powder to Pellets

In the NPK production process,granulation is the most critical step in the production of NPK fertilizers. The uniformly mixed materials enter the granulator at the specified feed rate, while saturated steam passes through the material layer, which not only increases the material temperature but also moistens it, creating optimal conditions for granulation.

Steam Conditioning

Appropriate steam passes through the material layer, increasing temperature and humidity to create an ideal environment for pellet formation.

Liquid Phase Control

When necessary, a small amount of water or fertilizer solution is sprayed to maintain the optimal liquid phase amount and ensure pellet quality.

Drum Action

The rotary drum granulator generates friction through rotation, forming uniform material pellets.

Pellet Movement

As the material rotates with the cylinder, the pellets slowly roll toward the outlet along the inclined direction, completing the forming process.

Finishing and Packaging: The Perfect Finish

After leaving the granulator, NPK fertilizer pellets are dried in a dryer, then screened, cooled, packaged, and stored. Throughout the npk fertilizer production process, unqualified particles are crushed and used as return material together with the screened powder, re-entering the granulation process to ensure zero waste and high efficiency.

As the core equipment in the NPK fertilizer manufacturing process, the rotary drum granulator is manufactured with special rubber lining or acid-resistant stainless steel lining, capable of handling various raw material combinations. Through processes involving steam, gas ammonia, or the addition of phosphoric acid, nitrogen solution, and other materials, efficient compound fertilizer granulation is achieved, ultimately producing uniform, efficient, and high-quality fertilizer products.
