Slow-Release Compound Fertilizer Production Line
Raw Materials
Urea-formaldehyde slow-release compound fertiliser production raw materials mainly include basic chemical raw materials, catalysts, neutralizers and auxiliary ingredients, the core of which is urea and formaldehyde through the polycondensation reaction to generate urea-formaldehyde resin.
Process Stages
1. Raw material pre-treatment: Crush large raw materials and mix them evenly. A condensation reaction is carried out in a reactor to form resin.
2. Granulation: Form the powdered mixture into granules with specific strength and particle size.

Granulation Process |
| Rotary Granulation |
5-30 tons/h |
Wet material is granulated by rolling in an inclined rotating drum. |
| Double Roll Granulation |
1-8 tons/h |
Dry powder material is formed through a die under high pressure without drying. |
| Disc Granulation |
1-10 tons/h |
A binder is sprayed onto a tilted rotating disc, and the material rolls into balls. |
3. Granule drying and cooling: Use a rotary dryer to reduce moisture, enhance strength, and cool granules to room temperature.
4. Controlled-release coating: Core process using a coating machine to apply semi-permeable layers (acrylic resin, sulphur, etc.).
5. Screening and Grading: Separate finished particles. Oversized particles are crushed; fine powders are returned for re-granulation.
6. Final Packaging: Automatic or manual palletising for packaging in woven or ton bags.
Frequently Asked Questions
Can I use this production line to produce multi granularity particles?
Yes, our production line is multifunctional. We can customize ring moulds of different sizes. In this way, you can easily adjust the size of your ball.
How to choose the most suitable machine if I know little about the line?
Just tell us your raw materials, capacity (tons / hour) and the size of the final particle product, and we will choose the machine for you according to your specific situation.
What if our workers don't know how to operate the production line?
Our engineers will instruct the site workers on how to install the machines and build the workshop, provide field tests, and train workers on operation.
What is the production period for the machines?
For a single fertilizer machine, production time is 7 days; for a whole production line, it is no more than 30 days.
What are the Quality Guarantee and Certifications?
All machines have passed ISO and CE certification. We guarantee the highest quality with a warranty time of 5 years after the shipment date.
