Rotary Drum Granulation Plant for Specialty Fertilizers like Granulated Calcium Fertilizer
- Capacity: 1-20 t/h
- Granule size: 2-8 mm
- Types of fertilizers: organic fertilizer, compound fertilizer, inorganic fertilizer, granular fertilizer, slow-release fertilizer, coated granules
- Material: Lined with rubber sheet for automatic removal of residue, reducing material adhesion, with a service life of 2-3 years. The drum granulator casing is typically made of carbon steel, with stainless steel available as a custom option.
- Granulation process: Wet granulation - produces denser, more uniform granules with a lower dust level in the workshop.
- Complete rotary drum granulation production line includes: batching machine - crusher - pulverizer - granulator - drying and cooling system - sifter - packaging machine (optional equipment depending on production capacity and material requirements).
The rotary granulator production line is primarily used for the granulation of phosphate-based fertilizers, such as monoammonium phosphate (MAP), diammonium phosphate (DAP), NPK fertilizers, and triple superphosphate (TSSP), among other products. It can also be used for the granulation of ammonia.
Finished Granules Effect
Why choose rotary drum granulation production line?
1. High capacity:
The production line is designed to meet the needs of large-scale production, with an annual output of up to 100,000 tons, suitable for medium and large fertilizer manufacturers.
2. Low formula requirements:
The NPK compound fertilizer production line has low requirements for raw material formula and can flexibly respond to different market needs and soil conditions.
3. Wet granulation process:
Steam is introduced into the drum granulator and mixed with the raw materials to promote the formation of granules. This process can improve the drying capacity of the fertilizer and reduce energy consumption.
4. Complete production process:
The production line includes multiple links such as raw material batching, mixing, granulation, drying, cooling, screening and packaging to ensure the efficiency and stability of the production process.
We also sell production line for:
| Organic fertilizer production lines | Compost powder fertilizer production lines |
| Compound fertilizer production lines | Inorganic fertilizer production lines |
| Chemical fertilizer production lines | Blended fertilizer production lines |
| Organic-inorganic fertilizer production lines | Bio-organic/microbial fertilizer production lines |

1. Raw material preparation & Batching
Based on the fertilizer formula, raw materials such as nitrogen, phosphorus, and potassium sources are selected and precisely measured using a batching system .
2. Crusher
The crusher can crush dry and wet materials. It is made of stainless steel and has strong corrosion resistance, or can be made of carbon steel for normal use.
3. Mixer
Make the material mix quickly and evenly, and reduce the material residue rate.
4. Rotary granulator
The mixed powder enters a rotary drum granulator, where a liquid binder (water or steam) is sprayed to promote adhesion. The drum's rotation causes the particles to agglomerate and grow into granules.
6. Dryer
Wet granules are transferred to a rotary dryer to reduce moisture content.
6. Cooler
Dried pellets are cooled to room temperature in a rotary cooler to prevent caking.
7. Screening & Recycling
Cooled granules are classified using vibrating screens. On-size pellets proceed to coating, while oversized/undersized particles are crushed and recycled back into the granulator.
8. Coating (Optional)
A coating may be applied to improve handling characteristics and control nutrient release.
8. Packing machine
The finished fertilizer is automatically weighed and packaged into bags for distribution.
