A fertilizer granulation plant helps you produce commercial fertilizer granules from organic powders, NPK mixtures, and mineral materials. YUSHUNXIN offers wet and dry granulation solutions for production capacities from 1 a 20 T/H and beyond. You can build a new plant or add granulation equipment to your existing powder fertilizer factory. Our engineers match granulators, secadoras, screeners, and packaging equipment to your raw materials, tamaño de gránulo objetivo, and budget.
What Raw Materials Can You Use in a Fertilizer Granulation Plant?
Organic fertilizer producers can granulate matured chicken manure, estiércol de ganado, estiércol de cerdo, mushroom compost, and suitable plant-based materials. For an línea de producción de fertilizantes orgánicos, we can connect crushing, mezclando, and granulation after composting.
NPK manufacturers often process ammonium sulfate, cloruro de potasio, sulfato de potasio, and other fertilizer ingredients. For an Línea de producción de fertilizantes NPK, we select equipment according to your formula, humedad, and required particle shape.
Mineral fertilizer producers may process phosphate rock powder, caliza, yeso, and selected mineral salts. For phosphate-based fertilizers, we can integrate rock phosphate processing with suitable crushing, molienda, and granulation equipment.
| Raw Material | Reference Preparation | Granulation Method |
|---|---|---|
| Low-moisture NPK powders | 5–10% moisture | Double roller compaction |
| Matured organic fertilizer powder | 20–40% moisture; around 50 mesh | Stirring tooth granulation |
| Organic or NPK fine powders | Alrededor 30% humedad | Disc granulation |
| Compound fertilizer mixtures | Formula-specific water or steam addition | Granulación con tambor rotatorio |
| Fibrous organic materials | Crushing and moisture adjustment | Flat die pelletizing |
Should You Choose Wet or Dry Fertilizer Granulation?
We can help you choose the granulation method according to your material moisture, required granule shape, and operating budget. Nuestro proceso de granulación húmeda de fertilizantes supports suitable organic and compound fertilizer formulas. Mientras tanto, el método de granulación seca de fertilizantes offers another option for low-moisture powders.
Wet vs. Dry Granulation
| Artículo | Dry Roller Granulation | Wet Granulation |
|---|---|---|
| Suitable Materials | Low-moisture NPK, mineral salts, selected powders | Organic fertilizer, NPK, fertilizante compuesto |
| Feed Moisture | 5–10% for roller compaction | 20–40% for stirring tooth models |
| Granule Shape | Pillow-shaped or irregular compacted granules | Round or near-round granules |
| Reference Granule Size | 3–10 mm | Depends on the granulator and screening |
| Core Equipment | Mixer, roller press, trituradora, evaluador | Granulator, secadora, enfriador, evaluador |
| Main Operating Costs | Electricity, roller wear | Electricity, drying fuel, water or steam |
Lower Drying Costs with Dry Granulation
Para 5%-10% low-moisture fertilizer powders, nuestro granulador de prensa de doble rodillo forms granules through mechanical compaction. You can avoid the main drying and cooling stages of wet granulation. This can reduce your investment in thermal equipment and related fuel consumption. Sin embargo, dry compaction produces a different granule shape from wet rolling granulation. If your customers require more round fertilizer granules, we recommend that you use a wet granulation process instead.
How Can We Design Your 1–20 T/H Fertilizer Granulation Plant?
Your target output determines the production scale. Mientras tanto, your material and granulation method determine the appropriate equipment. We will help you select the main granulator first, then choose the supporting machines to your desired finished-product output.

Complete Production Line Configuration
Para granulación húmeda, we can arrange:
Trituración → Dosificación → Mezcla → Granulación → Secado → Enfriamiento → Cribado → Envasado
For dry roller granulation, podemos usar:
Batching → Mixing → Roller Compaction → Crushing and Sizing → Screening → Packaging
Our SXZGZ-1870 granulador de tambor rotatorio offers a capacity of 5–8 T/H. For higher output, you can consider the SXZGZ-2080 or larger configurations. We also can choose suitable dryer, enfriador, evaluador, and conveyor to match your finished-product target. This helps prevent smaller downstream equipment from limiting production.
For finished fertilizer packaging, we can connect suitable equipo de envasado de fertilizantes after screening and other finishing steps. Besides, you can add an automatic palletizing machine to stack finished fertilizer bags onto pallets and reduce manual handling before storage and shipping.
Can Your Fertilizer Granulation Plant Produce 2–5 mm or 3–6 mm Granules?
Sí. We can configure your fertilizer granulation plant around target sizes such as 2–5 mm or 3–6 mm. Our team combines suitable granulators, ajuste de humedad, and screening to control the finished product.
Granule Size Control
For 2–5 mm organic fertilizer granules, our stirring tooth granulator offers a suitable configuration. Its feeding conditions include 20–40% moisture and approximately 50-mesh material. You can adjust feeding rate and stirring speed according to your fertilizer formula.
For 3–6 mm NPK granules, a rotary drum granulator supports continuous wet granulation. Water or steam addition, drum speed, and feeding rate help control granule growth.
For smaller spherical granules, nuestro granulador de disco supports a particle-size range of 1–8 mm. You can adjust water addition and disc inclination to control granule growth. Después, screening separates granules according to your required product size. Mientras tanto, dry double roller granulation can produce 3–10 mm compacted granules.
Rotary Screening for 2–5 mm Granules
After granulation and suitable drying, fertilizer enters a rotating cylindrical screener. As the drum turns, granules move across different screening sections.
For a 2–5 mm product, we can arrange two nominal separation points:
- Below 2 milímetros: Fine material passes through smaller openings and returns for further granulation.
- 2–5 mm: Qualified granules pass through the next screening section and continue toward packaging.
- Above 5 milímetros: Oversized granules leave through a separate outlet and enter a crusher before recycling.
Separate discharge chutes and conveyors guide each fraction to its next processing stage. We adjust screen openings, drum speed, inclination, and feeding rate according to your material. This helps you recover off-size fertilizer and collect granules within your target size range.
How Much Does a 1–20 T/H Fertilizer Granulation Plant Cost?
The price of a fertilizer granulation plant depends on production capacity, tecnología de granulación, and equipment scope. Our previous project estimates provide the following initial budget references.
Fertilizer Granulation Plant Reference Prices
| Production Solution | Reference Investment |
|---|---|
| 1–5 T/H Disc or Double Roller Granulation | Approximately $100,000–200,000 |
| 5–10 T/H Stirring Tooth Granulation | Approximately $200,000–350,000 |
| 10–20 T/H Rotary Drum Granulation | Approximately $400,000–550,000 |
These historical ranges provide initial budget guidance, not fixed quotations. Disc and double roller projects can require different equipment within the same broad investment range.
Main Equipment and Additional Costs
| Cost Item | Equipment or Requirement |
|---|---|
| Material Preparation | Crushers, batching machines, mezcladores |
| Granulación | Main granulator and feeding equipment |
| Secado y enfriamiento | Rotary dryer, enfriador, heat source |
| Screening and Recycling | Rotary screener, trituradora, return conveyors |
