Rotary Drum Granulation System

Rotary Drum Granulation System

Are you looking for an effective solution for industrial production of fertilizer granules? Do you want to purchase an erosion-resistant system for large-scale fertilizer granulation?? Here, rotary drum granulation system can fully meet your needs. Thanks to the use of the wet granulation method and its rotating drum design, will help you transform fertilizer powder into 3-6mm granules quickly. Besides, in order to produce fertilizer granules more stable and efficient, we have optimized the interior design of the equipment, reducing adhesion to walls and improving overall granulation efficiency. For this reason, It can be used both in the manufacture of compound fertilizers and in the production of organic fertilizers.. In addition, YUSHUNXIN offers customized rotary drum granulation system solutions for fertilizer pellet production with capacities between 1 and 30TPH and costs between 90000 and 600000USD, among other parameters.

Why buy a rotary drum granulation system for your fertilizer pellet plant?

Rotary 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??

Large scale fertilizer granulation with single drum granulator

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

Production of NPK 3-6mm granules according to your requirements

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 quote

Advice: During granulation, The water content should be maintained between 20% and 40%. This range is optimal to obtain quality fertilizer pellets.

Production of commercial fertilizer granules with spherical shape

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 quote

Three designs of drum granulator to improve the erosion resistance during pellet manufacturing

In 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.

What technology does the rotary drum granulation line adopt to transform fertilizer powder?

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.

How to establish a fertilizer drum granulation plant?

If you want to install a rotary drum granulation system plant, It is not enough to buy the granulator: It is essential to select other fertilizer processing equipment to form a complete line. In this process, You must mainly consider the total cost and the necessary area of ​​the plant. For this reason, to build a rotary drum granulation factory, The following points are required to be addressed:
  • Equipment needed in a fertilizer rotary drum granulation line

    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.

  • How much does it cost to establish a drum fertilizer granulation plant?

    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.

  • What area requires a drum fertilizer pellet production system?

    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.

Design of rotary drum granulation system for USD300,000 compound fertilizer project

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..

Can rotary drum granulation system process manure compost into fertilizer pellets?

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..

Recent drum organic fertilizer granule production projects

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.
