Learn moreRotary drum granulation line is widely used in industrial production of granular fertilizers, especially in large scale compound fertilizer granulation. Because? What can it contribute to your granule production project??

When it comes to an industrial fertilizer granulation project, The best option is to set up a rotary drum granulation line. One of the main reasons is that this line can sustain a production of 1a30TPH with a single piece of equipment installed..
For example, if you want to produce 8-15tons of pellets per hour, we can provide you SXZG-2080 rotary drum granulator. Besides, for larger scale pellet manufacturing, you can choose SXZGZ‑3210 drum granulator machine, with a capacity of 15-30t/h. Of course, We also have various rotary granulation equipment for smaller scale productions., de1a8TPH. Free quote
Can the rotary drum granulation system make particles with the diameter you need?? Of course. Normally, This granular fertilizer production plan converts chemical powder into 3‑6mm pellets, size widely used in agriculture.
How is the granule size regulated during rotary granulation?? By adjusting the moisture content or controlling the drum rotation speed. The higher the humidity, larger granule size; at lower humidity, smaller size. Also, when the speed is higher, size decreases, and when the speed is lower, granules increase. Free quoteAdvice: During granulation, The water content should be maintained between 20% and 40%. This range is optimal to obtain quality fertilizer pellets.

Besides, This system constitutes an ideal option for the production of commercial spherical fertilizer granules.
This is because, for those engaged in large-scale agriculture, round-shaped fertilizer granules are more suitable for mechanical application, since they avoid obstructions and guarantee greater uniformity. Free quoteIn the large-scale fertilizer granulation process, There is one aspect that most fertilizer manufacturers focus on. Due to wet granulation, materials tend to stick easily to equipment walls. This affects the efficiency of the rotary drum granulation system and accelerates equipment wear.. to solve it, We have developed the following improvements:
For granulation equipment to withstand erosion from large-scale compound fertilizer processing, The best strategy is to increase its corrosion resistance. Starting from the use of Q235B boiler steel (or stainless steel optional) to manufacture the drum granulator, we equip it with an interior lining of rubber. This way, The equipment offers greater resistance to erosion and a longer useful life.


To reinforce the anti-corrosion protection of the rotary drum granule production system, Pressed stainless steel bands are installed over the rubber coating. These firmly fix the coating to the inner wall of the drum, and thanks to stainless steel, They have high resistance to erosion.


After prolonged operation, materials can still accumulate on the interior wall, affecting the granulation efficiency of. How to remove such waste? They can be cleaned through special holes: by gently hitting these points with a hammer, vibrations cause adhered materials to loosen.


| Model | Power (kW) | Diameter (mm) | Length (mm) | Installation angle | Rotation speed (rpm) | Ability (t/h) |
| SXZGZ-1240 | 5.5 | 1200 | 4000 | 2-5° | 17 | 1-3 |
| SXZGZ-1560 | 11 | 1500 | 6000 | 2-5° | 17.5 | 3-5 |
| SXZGZ-1870 | 15 | 1800 | 7000 | 2-5° | 11.5 | 5-8 |
| SXZGZ-2080 | 18.5 | 2000 | 8000 | 2-5° | 11 | 8-15 |
| SXZGZ-3210 | 37 | 3200 | 10000 | 2-5° | 9.5 | 15-30 |
As mentioned, rotary drum granulation line uses wet granulation method to convert fertilizer powder into granules. During this process, takes advantage of the cohesion of a liquid agent that allows powder particles to agglomerate and form granules in 3-5 minutes. Depending on the needs, You can opt for cold or hot granulation technologies.
Por lo general, cold granulation is the most common in rotary drum granulation system, since the process is simple and energy consumption is reduced. Only spraying water or a liquid cohesion agent is required to moisten the material, which favors the formation of the granule, and the entire process occurs at room temperature. At YUSHUNXIN we have customized drum granulators with professional liquid spray systems.
If you are looking to prepare fertilizer pellets on a large scale in less time, steam can be injected into the drum granulation process. On the one hand, the steam moistens the dust, creating an adhesive surface that favors the bonding of particles; for another, raises the internal temperature of the granulator, which accelerates the solidification and hardening of the granule. Therefore, It is an ideal option for manufacturing high concentration compound fertilizers.
When planning a compound fertilizer granulation line, addition to rotary drum granulator, you will have to purchase a dosing machine, crusher, mixer, sieve, secador, cooler, dust collector, powder drop chamber, coating and conveyor equipment. If it is a line of organic fertilizers, You may also need a dehydrator and a composting machine large capacity.
Cost plays a crucial role in installing rotary drum granulation system, since it includes the value of the equipment, the construction of the workshop, energy consumption and labor, among other factors. This cost is closely related to production capacity.: with an output of 1‑30t/h, Approximate budget of 90000 to 600000USD is needed for a complete line. However, by dealing directly with the manufacturerYUSHUNXIN, you can get equipment at more competitive factory prices.
The land area required also varies depending on the capacity and configuration chosen. In general, A 5t/h drum granulation line requires an area of 3000‑4500m², while a 20t/h line needs between 5500 and 10000m² for installation.
To implement a 300000USD compound fertilizer granulation line with drum granulator, There are two standard solutions that completely cover the production needs of 8-20TPH granules..
If you want to install a NPK granulation plant de8-15TPH, you can purchase a complete rotary drum granulation system with integrated dosing processes, granulation and packaging, like him 300,000USD NPK granulation project in Bolivia. Through these stages, Composite granules with balanced nutrients are obtained, uniform size, without caking and with better storage capacity.
Is it possible to establish a rotary drum granulation system for the compound fertilizer production de 20 TPH por 300 000 USD? Of course. For this, It is recommended to first acquire the essential equipment for the production of compound fertilizers: dosage units, rotary drum granulators, drying and cooling systems, and semi-automatic bagging equipment. This setup balances productivity and investment, while guaranteeing the quality and stability of the final product.
As explained, rotary drum granulator is an excellent choice for large scale compound fertilizer manufacturing (including NPKy phosphate fertilizers). But, Is it also suitable for produce organic fertilizer granules? The answer is yes. Its high corrosion resistance allows it to process large volumes of manure compost quickly and efficiently..
For example, A client inquired about the fertilizer plant from cow manure in Mexico , indicating your intention to process manure with 90% moisture to obtain 3-4mm organic granules. Finally, This Mexican customer chose a 20TPH rotary drum granulation system with double dryer, and currently obtains benefits from its line of organic fertilizers.
In addition, Customer sent positive feedback for their 10TPH biofertilizer production project with drum granulation line in Argentina, where cow manure and chicken manure waste are processed to convert them into high quality biofertilizer pellets. Hoy, This Argentine manufacturer has expanded its annual production of bio-granulated fertilizers up to 60,000 tons.
