Fertilizer Pelletizers – Professional Equipment for Agricultural Granulation
High-Compression Technology for Organic, Mineral and NPK Fertilizers
Meelko’s fertilizer pelletizers are engineered to transform organic matter, mineral inputs and dry agricultural blends into uniform, dense and easy-to-apply pellets.
Using high-pressure flat dies, these machines produce commercial-grade granules suitable for farm use or large-scale distribution.
This equipment is ideal for farmers, composting operations, fertilizer manufacturers, cooperatives and companies seeking to add value to raw material, improve handling, and produce granular fertilizers with greater precision and efficiency.
Compatible Materials
Our pelletizers can process a wide range of inputs commonly used in fertilizer production:
Organic Fertilizers
- Compost
- Vermicompost (worm castings)
- Dried and pulverized manure
- Composted plant residues
- Treated poultry litter or guano
Mineral Fertilizers
- Natural phosphates
- Bone meal
- Agricultural limestone (calcium carbonate)
- Gypsum (calcium sulfate)
- Soil enhancers and corrective minerals
NPK Blends
- Dry granular mixes (after proper milling)
- Organic–mineral blends
- Precision formulas for specific crops
Soil Conditioners and Biofertilizers
- Zeolite
- Rock powders and trace minerals
- Treated ash
- Bio-stimulant dry bases
Advantages of Fertilizer Pellets
- Accurate application: uniform pellet size for manual or mechanized spreading.
- Improved efficiency: less wind drift and better soil incorporation.
- Dust reduction: cleaner handling and storage.
- Extended shelf life: pellets resist moisture and microbial degradation.
- Higher density: lower transportation and storage costs.
- Custom formulation: producers can design their own recipes and nutrient mixes.
Material Requirements for a Stable Pellet
To achieve durable fertilizer pellets, the following conditions are recommended:
- Moisture content: 10% to 18%, depending on material type.
- Particle size: 2–5 mm after milling for optimal compaction.
- Homogeneous mixing: essential for NPK and organic–mineral blends.
- Removal of stones and metal fragments: protects the die and rollers.
- Optional post-drying: improves hardness and final stability for commercial pellets.
