In the field of fertilizer production, rotary drum granulator is the core equipment to improve efficiency and quality, especially suitable for large-scale processing of organic fertilizer and compound fertilizer production lines.

Its working principle fits the characteristics of fertilizer raw materials: when organic fertilizer raw materials such as livestock and poultry manure, crop straw, or basic materials of compound fertilizer such as nitrogen, phosphorus and potassium enter the inclined rotating drum, the materials are constantly lifted and dropped as the drum continues to rotate. At the same time, the special atomization system will accurately spray the right amount of water or binder, so that the material particles will adhere to each other in repeated collisions, and gradually gather into particles of uniform size like a snowball. These particles move slowly to the discharge port in the drum. After screening, the fertilizer particles that meet the standards are transported to the subsequent process, and the fine powder returns to the drum for granulation again, forming an efficient circular production mode, and the granulation rate can reach more than 80%, which perfectly meets the forming requirements of fertilizer particles.
The advantages of rotary drum granulator in the field of fertilizer are extremely prominent. First of all, it can adapt to a variety of fertilizer raw materials. Whether it is sludge with high water content, sludge, or dry fertilizer powder, it can achieve stable granulation by adjusting the drum speed, material ratio and spray volume. There is no need to frequently change equipment for different raw materials, which greatly reduces the production cost of the fertilizer plant. Secondly, the fertilizer granules produced have obvious advantages. The granules are round and of moderate hardness. They are not only easy to transport and store, reducing losses during transportation, but also can be evenly scattered during application, improving the utilization rate of fertilizers and avoiding soil pollution caused by excessive local fertilizers. Furthermore, the production efficiency is high and stable. A single device can produce several tons to tens of tons of fertilizers per hour, which can easily meet the mass production needs of large fertilizer companies, and the energy consumption during operation is low, saving a lot of operating costs for the company.
For fertilizer production companies, the rotary drum granulator is undoubtedly an ideal choice to enhance competitiveness. It can not only ensure the quality of fertilizer products, but also improve production efficiency, helping companies to occupy a dominant position in the fertilizer market.
