Rotary drum granulator: It is the core equipment of the drum granulation production line and is used to form mixed raw materials into granules. The drum granulator consists of a rotating cylinder with lifting plates or fins inside. The raw materials gradually form particles as they roll and flip inside the cylinder.
Drum Dryer system: Including rotary dryers, fluidized bed dryers and other equipment, used to remove moisture from the particles and improve the strength and stability of the particles.
Drum Cooler system: Including equipment such as coolers or cooling fans to reduce the temperature of the particles and prevent them from clumping or deforming during packaging and storage.
Rotary Drum Screening system: Including equipment such as vibrating screens and rotary vibrating screens, which are used to screen particles, remove particles that are too large or too small, and ensure the uniformity of the product.
Fertilizer Packaging system: Including automatic packaging machines, weighing packaging machines and other equipment, used to package granular products into bags or bulk products of different specifications for easy sales and transportation.
The above equipment constitutes a typical drum granulation production line, and different production lines may vary slightly depending on production requirements and scale.
The basic process of granulating NPK compound fertilizer in the drum granulation production line
The drum granulation production line is a process commonly used to manufacture fertilizers, granular fertilizers and other products. The following is a detailed process of NPK fertilizer granulation:
Raw material preparation: Prepare main raw materials such as N (nitrogen), P (phosphorus), K (potassium) and auxiliary raw materials. These raw materials are usually the main components of nitrogen fertilizers, phosphate fertilizers and potassium fertilizers, and can be urea, diammonium phosphate, potassium chloride, etc.
Preprocessing: Raw materials need to undergo preliminary processing, including grinding, mixing, etc., to ensure even distribution of various ingredients. This can be accomplished with mechanical grinding and mixing equipment.
Wet mixing: Mix the pretreated raw materials with water to form a mixture. This helps the ingredients combine better and form particles.
Wet granulation: The mixture is fed into the drum granulator. This machine uses a rotating drum and the help of additives to form the mixture into preliminary granules. At this stage, the wet mixture is formed into a series of small spherical particles.
dry: Dry the wet pellets through a desiccator to remove excess moisture. This helps improve the strength and stability of the pellets.
Screening: The dried particles need to be screened to remove particles that are too large or too small to ensure the uniformity of the product.
cool down: The screened particles are cooled to lower their temperature. This helps prevent clumping or other problems with the pellets during packaging and shipping.
Package: The final NPK fertilizer granules are packaged into appropriate packaging specifications for easy sale and transportation.
The above is the basic process of NPK fertilizer granulation. In actual production, there may be some additional steps or specific equipment for different types of products and production requirements.
How to use drum granulation production line to granulate chicken manure organic fertilizer?
The drum granulation production line is a piece of equipment commonly used to turn organic waste such as chicken manure into organic fertilizer. The production line is mainly composed of crusher, mixer, drum granulator, screening machine, dryer, cooler, packaging machine, etc.
First, organic waste such as chicken manure is processed through a grinder to break it into fine particles. The crushed chicken manure is then put into a mixer with other organic materials for mixing to achieve even distribution.
Next, the mixed materials are fed into the drum granulator for granulation. The drum granulator uses the internal drum rotation and high-speed friction to compress the material into granules and discharge them through the discharge port. At the same time, the drum granulator can also be adjusted according to different particle size requirements to meet the needs of different customers.
Subsequently, the granules are screened through a screening machine, and the unqualified granules are sent back to the drum granulator for granulation again. The screened particles are then sent to a dryer for drying to remove moisture from the particles. The dried particles also need to be cooled by a cooler to reduce the temperature of the particles and avoid deformation of the particles during the packaging process.
Finally, the pellets are packaged by a packaging machine to become the final product. The high degree of automation of the entire production line can greatly improve production efficiency and product quality, while also reducing the difficulty and labor intensity of manual operations.
The drum granulation production line has a good granulation effect on chicken manure. It can produce organic fertilizers with regular particle shapes and uniform particle sizes. It can also be adjusted according to different customer needs. This production line has a wide range of applications and is suitable for agriculture, gardening, environmental protection and other fields, providing an environmentally friendly and efficient solution for the comprehensive utilization of waste.

Rotary drum granulator making line is an important technical means of wet granulation production line
Wet granulation is the most widely used technology in fertilizer granulation production lines. It is widely accepted because of its wide applicable scope of raw materials, high production efficiency, good granular shape and high strength after drying.
The rotary drum pelletizer production line is mainly used for the granulation of phosphorus compound fertilizers, such as monoammonium phosphate（MAP), diammonium phosphate(DAP), nitrogen-phosphorus-potassium compound fertilizers(NPK), heavy calcium superphosphate and many other products(TSSP). It is also used for ammonia granulation.
Meanwhile, rotary drum pellet making line is also widely used in the production of organic and inorganic compound fertiliser.
What is the difference between drum granulation production line, disc granulation production line and extrusion granulation production line?
In EMCC, there are three fertilizer granulation production lines that are very popular among fertilizer suppliers. They are drum granulation production line, disc granulation production line and extrusion granulation production line. However, they have some limitations in their working principle, scope of application and product characteristics. There are some differences:
Drum granulation production line:
- Working principle: The drum granulator uses a rotating cylinder with a lifting plate or fin inside to make the raw material into particles by using the rotating motion and the internal lifting plate or fin.
- Scope of application: It is suitable for making particles of powdered or wet raw materials, such as fertilizers, granular fertilizers, etc.
- Product features: The particle shape is relatively regular, but it is easily affected by the properties of the raw materials, and the control of particle size and shape is relatively difficult.
Disc granulation production line:
- Working principle: The disc granulator makes the raw material into particles through a rotating disc. Inside the disc, the raw materials and additives are continuously rolled and extruded to form particles.
- Scope of application: It is suitable for making particles of powdered or wet raw materials, such as fertilizers, granular fertilizers, etc.
- Product features: The particle shape is relatively regular, and the requirements for raw materials are relatively high, but relatively precise particle size and shape control can be achieved.
Extrusion granulation production line:
- Working principle: The extrusion granulator squeezes the raw materials into particles through the extrusion mechanism. The raw materials pass through the extrusion port and form particles under the action of the extrusion force.
- Scope of application: Suitable for making some special shapes or high-density particles, such as pellet fuel, tablets, etc.
- Product features: The particle shape can be adjusted more flexibly, and particles with higher density can be produced, but the requirements for raw materials are also higher.
In general, these three granulation production lines have their own characteristics, and the appropriate production line can be selected according to different production needs and product characteristics.
