The compound fertilizer granulation production line is a production process without drying and at room temperature, including raw material batching, mixing, granulation, drying, cooling, grading, coating and packaging. The production line has low investment, quick effect, compact layout, scientific and reasonable, advanced technology, energy saving and consumption reduction, stable operation and convenient maintenance. It is suitable for granulation of various raw materials.

1. Raw material preparation: Urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate (monoammonium phosphate, diammonium phosphate, heavy calcium, general calcium), potassium chloride (potassium sulfate) and other raw materials are prepared in a certain proportion (according to market demand and soil test results in various places).

2. Raw material mixing: Mix the prepared raw materials evenly to improve the uniform fertilizer efficiency content of the fertilizer particles as a whole.

3. Raw material granulation: Send the mixed raw materials to the granulator for granulation (drum granulator or extrusion granulator can be used).

4. Granule drying: Send the granules made by the granulator to the dryer to dry the moisture contained in the granules, increase the strength of the granules, and facilitate storage.

5. Granule cooling: The temperature of the dried fertilizer granules is too high and easy to agglomerate. After cooling, it is easy to bag, store, and transport.

6. Granule grading: The cooled granules are graded, the unqualified granules are crushed and re-granulated, and the qualified products are screened out.

7. Finished film: The qualified products are coated and coated to increase the brightness and roundness of the granules.

8. Finished product packaging: Put the film-wrapped particles, i.e. the finished product, into bags and store them in a ventilated place.

1. High product quality: The raw materials are strictly formulated to ensure balanced nutrients. The pellets are round, full, uniform in size, and compact.

2. High production efficiency: The production line is equipped with an automated control system and a powerful and efficient mixer to quickly blend the raw materials and improve production efficiency.

3. Good environmental performance: Complete dust collection and exhaust gas purification system, environmental protection design throughout the entire production process.

4. Wide adaptability of raw materials: Suitable for granulation of various raw materials such as compound fertilizers, medicines, chemicals, feeds, etc., and can produce various concentrations and types of fertilizers.

5. Good after-sales service: Professional after-sales team accompanies the whole process from the first day of equipment installation, and installation and commissioning problems can be solved on site immediately. Sudden failures in daily production will be responded to within 24 hours.

The professional after-sales team is on call at any time. Once you encounter any problems during the installation and commissioning of the equipment, they will rush to the site as soon as possible and use their superb technology to ensure the smooth start-up and operation of the production line. In the subsequent daily production, if the equipment fails, just one phone call and the after-sales staff will respond within 24 hours, quickly diagnose the problem and provide a solution. Regular equipment maintenance services are even more indispensable. The after-sales team will develop a personalized maintenance plan based on your production situation, conduct a comprehensive “physical examination” for the equipment on site, replace wearing parts, and ensure that the production line is always in the best operating condition. In addition, we also provide customers with operation training services, so that your employees can quickly become familiar with the equipment operation process, master basic maintenance knowledge, and reduce problems caused by improper human operation.
