The roller compacting granulator is highly appreciated by many fertilizer manufacturers., especially in the NPK granule production plants, since it allows fertilizer granulation to be completed quickly and with a reduced investment. The machine adopts dry granulation method, which is mainly based on the physical extrusion force that is generated between two rollers to transform the chemical powder into compact granules.. Besides, If you want to start an organic fertilizer granulation project, This equipment can completely satisfy your requirements. Together with the roller compactor for pelletizing, We can also provide you with the corresponding equipment to form an industrial granulation line by roller compaction for the manufacture of fertilizers..
Learn moreAre you interested in the double roller granulator machine? Do you plan to use it in your fertilizer production project?? First of all, It is important to know the granulation method applied by this system.
This pelletizing equipment uses dry granulation, which almost completely converts the chemical material into granules without adding water. It is mainly based on the extrusion force between the two rollers to granulate compound fertilizers..
Thus, no subsequent drying or cooling processes required, which allows the manufacturing of the compound fertilizer particles to be completed through a simpler process and at a significantly lower cost. Free quoteBesides, It is based on the extrusion that is generated between the two rollers to form the compound fertilizer granules., while the moisture content of the materials must be less than 10%.
A direct and effective way to choose a suitable granulation machine is to evaluate the final granule obtained. Entonces, What kind of fertilizer granule can the pelletizing roller compactor produce for you?? Por lo general, The fertilizer granule obtained using this equipment has three notable characteristics:
What is the size of final granule generated by roller press granulator? This is an aspect that most fertilizer manufacturers look at carefully.. In general terms, Our roller extrusion compactor can make compound fertilizer particles with a diameter of 3-10mm., fully meeting your needs. How to adjust granule size during roller granulation? Thanks to the use of the roller compaction method, the size depends on the volume of the alveoli or cavities of the two roller plates. Por tanto, when you want to modify the granule size, The most appropriate way is to use rollers with the cavity of the required dimension.
In addition to the size of the cavities in the roller blade, You have a wide range of options in terms of shape. We can manufacture cushion-shaped cavities, semicircle, barra, pill, nut, flat ball or square bar, according to your specifications. Así, Whether you want to produce oval shape chemical fertilizer granules, irregular, wheat type or other configurations, you can achieve it easily and quickly.
Is it possible to transform roller compactor granules into totally spherical particles? You only need to add a fertilizer polishing machine after the main compaction equipment.
What then is the difference between granules obtained by roller compaction and those produced by disc granulation or rotary drum pelletization?? The most obvious difference lies in the hardness. Roller extrusion granulation equipment can offer you NPK composite granules or even granulated deicing agents with higher hardness than other chemical material granulation equipment.. The hardness can reach values of 10 to 52N, which means that the final particles of compound fertilizer have a low probability of being pulverized and are more convenient for transportation, storage and application.

In general terms, Pelletizing roller compactor can fully meet your fertilizer granule manufacturing requirements, offering capacities from 1 to 20 TPH, a high granulation rate of 95% and an economical price…
In order to meet the different capacity requirements of manufacturers, We specially design various models of roller compaction machines: SXDG‑1T, SXDG‑2.5T, SXDG‑4T, among others. If you want to start a small scale compound fertilizer production with a capacity of 1-20tons per hour, These models are the optimal option.
Are you looking for granulation of fertilizer powder materials with high efficiency? Do you want to purchase a granulator for compound or organic fertilizers with a low material return rate?? En ese caso, We recommend the roller compactor. Its granulation rate can reach 95%, so only a minimal fraction of material needs to be reprocessed, allowing you to simultaneously obtain more qualified fertilizer granules.
When using roller compaction equipment for fertilizer granulation, you can reduce costs in two aspects. On the one hand, Its price is extremely competitive: With only US$4500–22000 you can purchase it. On the other, as mentioned above, the roller compaction pelletizing process does not require drying or cooling systems, especially in the production of granular compound fertilizers. For this reason, The total cost of a dry extrusion granulation line with capacity of 1–20TPH ranges only between US$50,000 and 200,000..
Whether you want to produce 20‑20‑20,20‑10‑10 fertilizers or other NPK formulations, or develop special high-quality compound fertilizers, medium or low concentration, the roller compactor can fully satisfy your demands. Besides, The quality of the final granule meets the technical requirements established for compound fertilizers.
Feed fertilizer materials precisely according to the established formula.
Grind NPK material to fine powder, which facilitates compaction by rollers.
Homogenizes the NPK powder to ensure a balanced distribution of nutrients in the final granules.
Compresses dry NPK powder quickly transforming it into fertilizer granules.
Separates NPK granules of the required size and returns particles that are too small or large for reprocessing.
Bag the final NPK granules according to the required weight, for example 10kg/20kg/50kg per bag.
Por lo general, There are two types of roller compaction granulation systems that are most frequently purchased by fertilizer granule manufacturers.: 1–4t/h small scale production line and 4–20t/h extrusion system for large scale productions.
If you plan to start a fertilizer granule manufacturing project with a capacity of 1a4t/h, you only need one set of roller extrusion granulator. A complete fertilizer granulation line usually includes the following equipment: static dispensing machine, triturador vertical SXFLF‑600 (3‑5 t/h), double shaft mixer, roller granulator, SXGS‑1240 rotary sieve (3‑5 t/h) and single bucket packaging machine.
When it comes to a granular fertilizer production project greater than 4t/h, It is possible to combine two or more roller compactors to work in parallel. At the same time, You can replace the other equipment with higher capacity models, as a dynamic dosing machine, molino vertical SXFLF‑1000 (10‑15 t/h), horizontal mixer, sifter SXGS‑2080 (10‑20 t/h) and double bucket packaging machine, inter alia.
If you want to know more precisely if the roller compactor is the right equipment for you, It is worth first understanding what types of fertilizers you can process. In general terms, It is appropriate for the following cases:
NPK Composite Fertilizer Manufacturing: To supply nitrogen, phosphorus and potassium to crops in a balanced way, It is essential to process the NPK fertilizer into granules. In this sense, Pelletizing roller compactor granulation equipment represents an ideal choice. Whether you want to produce formulations 20‑20‑20,20‑10‑10or other NPK fertilizer variants, The system can complete the task quickly and easily.
Snow melting agent granulation: Roller extrusion granulator is also widely used in the manufacturing of deicing agents. After granulation, the product is not only more effective, but also easier to package, transport and store. Besides, using this extrusion equipment for granule formation, snow melting agent can be converted into solid particles at significantly lower cost.
Of course. As long as the moisture content of the material is less than 20%, many types of powders can be transformed into fertilizer granules by roller compaction. These include:
Normally, Standard material of roller plates is 20GrMoTio steel stainless steel 4Cr13. To maintain the correct operation of the roller compaction granulation line, It is recommended to replace the blades or rollers every 6 to 12 months.
