Tongli rotary drum granulator is a key equipment in compound fertilizer industry. It works by wet granulation. A certain amount of water or steam is used to make the basic fertilizer fully react chemically after being humidified in the cylinder. Under certain liquid phase conditions, the rotating motion of the cylinder makes the material particles produce extrusion force to agglomerate into balls. It is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizers. The granulation rate is 70%, the average granulation strength is >10N, the product nutrients are uniform, and the adaptability is strong. Steam is introduced from the machine, and phosphoric acid or ammonia solution, slurry, etc. can also be added to complete the compound fertilizer production process of chemical reaction in the cylinder; it can also be used for compound fertilizer production process of adding water and humidification.

QUALITY NEVER GOES OUT OF STYLE
A rotary drum granulator is equipment designed to process powdery materials into uniform granules, widely used in compound fertilizer production. Its core component is a rotating drum, typically 1.5 to 4 meters in diameter and 5 to 12 meters in length. Inside the drum, materials undergo friction, compression, and adhesion to gradually form granules.
This equipment is suitable for compound fertilizer production lines with annual capacities ranging from 50,000 to 200,000 tons. Through continuous rotation and mixing, materials within the drum are uniformly stressed, and with the addition of binders and moisture, they gradually form granules and are discharged.
The granulated compound fertilizer produced is characterized by high uniformity and even nutrient distribution, suitable for various crops. The design of the rotary drum granulator also includes dust removal and cooling systems to ensure environmental protection and product quality during production.
Rotary drum granulators provide several advantages in compound fertilizer production. Firstly, they have strong processing capabilities, typically handling 5 to 30 tons of materials per hour, with annual outputs reaching over 100,000 tons, suitable for large-scale industrial production.
Secondly, the granulation rate is over 90%, resulting in well-formed, uniform granules with stable product quality. Additionally, the equipment is compact, occupies minimal space, is easy to operate, and simple to maintain, making it suitable for producing various compound fertilizer formulations.
The equipment is also energy-efficient, reducing energy consumption by 15% to 30% compared to traditional equipment through the use of efficient motors and variable frequency drives. Equipped with high-efficiency dust removal and cooling systems, it ensures environmental protection and product quality during production, meeting modern agriculture's demands for efficient, eco-friendly, high-quality fertilizers.
The operating parameters of a rotary drum granulator, including speed, humidity, temperature, and binder dosage, directly impact granule quality. The speed is generally between 10 to 20 RPM; higher speeds aid in forming smaller granules, while lower speeds are suitable for larger granules.
Humidity is typically controlled between 40% and 60%; too high or too low affects granule hardness and shape. Temperature is maintained at 50 to 80 degrees Celsius to aid drying and binder distribution; too high may cause granule breakage, and too low may lead to poor adhesion.
Binder dosage is generally 2% to 5% of the total material. Insufficient binder results in weak granules, while excess increases costs and may cause adhesion issues. Precise control of these parameters can effectively enhance granule quality, ensuring even nutrient distribution in compound fertilizer.
Selecting suitable specifications for a rotary drum granulator involves considering annual output, material characteristics, and granule requirements. For a 100,000-ton annual production line, a drum granulator with a diameter of 2.2 meters and a length of 8 meters is typically chosen.
Production needs include hourly output and granule size requirements, while material characteristics involve raw material viscosity, humidity, and temperature requirements. Equipment power should range between 75 to 110 kW to ensure production efficiency.
Considering energy consumption and space, choose energy-efficient, compact equipment. Additionally, consider factors such as energy consumption, ease of maintenance, and space requirements to achieve optimal production efficiency and economic benefits. By comprehensively considering these factors, the most suitable rotary drum granulator specifications can be selected, ensuring continuous and stable production while enhancing product quality and market competitiveness.
A rotary drum granulator adapts to raw material changes by flexibly adjusting parameters. Depending on the material's characteristics, such as viscosity and moisture, the drum speed (10 to 20 RPM), temperature (50 to 80 degrees Celsius), and binder dosage (2% to 5%) are adjusted.
The equipment's versatility allows quick adaptation to different raw material production needs. Regular process tests and equipment calibration ensure parameter accuracy and stability. By monitoring and adjusting production parameters in real-time, raw material changes can be promptly addressed, ensuring continuous and stable production.
Additionally, optimizing production processes and equipment configurations can enhance the adaptability to raw material changes. Applying these measures comprehensively ensures efficient operation of rotary drum granulators under different raw material conditions, improving production efficiency and product quality.
Regular maintenance is crucial for enhancing both the efficiency and lifespan of a rotary drum granulator. By routinely inspecting components such as bearings, seals, and the drum itself, potential issues can be identified and addressed before they lead to major problems.
Ensuring that all parts are properly lubricated reduces friction and wear, promoting smoother operation and preventing unnecessary downtime. Cleaning the equipment regularly prevents material buildup, which can affect performance and cause blockages.
Additionally, calibrating the granulator periodically ensures optimal operation settings, leading to consistent granule quality and reduced energy consumption. By implementing a comprehensive maintenance schedule, the granulator can operate at peak efficiency, extending its service life and improving overall productivity.
NPK compound fertilizer contains three basic nutrients, nitrogen, phosphorus and potassium. It is processed into uniform particles by a granulator and is one of the most commonly used fertilizers in agriculture.
BB fertilizer is a mixed fertilizer, usually mixed with a variety of basic fertilizers. When applied, it can more accurately meet the needs of different elements in the soil and ensure uniform distribution of nutrients.
Made from natural organic matter, such as livestock and poultry manure, plant residues, etc., it is rich in organic matter and trace elements. After being processed by a granulator, the particles are easier to apply and the odor is reduced.
Single fertilizers such as ammonium sulfate and potassium chloride contain a single nutrient component and are mainly used to quickly supplement specific nutrients.
Slow-release fertilizer is produced by a granulator to provide continuous release of nutrients, slow down nutrient loss and improve utilization. It is suitable for reducing the number of fertilizations, improving crop growth and soil environment.
Contains beneficial microorganisms and organic matter to promote microbial activity and nutrient circulation in the soil. Granulation makes it easier to apply, improves soil fertility and plant growth environment, and is an environmentally friendly agricultural choice.
This fertilizer is rich in phosphorus and nitrogen and is ideal for early crop growth. Granulated particles reduce fertilizer volatilization and loss and improve absorption efficiency.
Potassium nitrate provides two important nutrients, nitrogen and potassium, which helps crops resist diseases and improve fruit quality.
