Organic Fertilizer Granulator Machine
What is an Organic Fertilizer Granulator Machine
If you want to produce organic fertilizer pellets, this organic fertilizer granulator machine is essential. It processes treated organic materials—like livestock manure, straw, and mushroom residue—into uniform cylindrical pellets. These pellets flow well and create little dust. They are also easier to transport and store.
Here is how the organic fertilizer granulator machine works. The material is squeezed and compacted by the ring die and the press roller. Then it is extruded through the ring die holes. Finally, a cutter trims it into pellets of uniform length.

How to Make High-quality Organic Fertilizer Pellets
How do you turn poultry manure, fruit pomace, and agricultural waste into organic fertilizer pellets? Granulation alone is not enough. There are many other steps before and after. Each step affects the final quality. If you don’t want to handle all the details yourself, you can also order a complete organic fertilizer production line.
01.
Preprocessing
Organic raw materials come from many sources. They may contain stones, metal scraps, wood chips, or feathers. This step removes these impurities. Cleaner materials help protect downstream equipment—like the turner, crusher, and organic fertilizer granulator machine—from damage.
02.
Fermentation
This is a key step that determines pellet quality. It also separates high-quality fertilizer from low-quality products. During production, you can adjust the carbon-to-nitrogen ratio and moisture level based on your raw materials. You can also add fermentation agents to speed up decomposition. A turner aerates the pile regularly. This supplies oxygen and creates good conditions for fermentation.
03.
Crushing
After fermentation, the material may look loose. But there are still lumps of different sizes inside. If the material is not uniform, it is not ready for granulation. Crushing breaks up these lumps into a fine, even powder. This helps with later mixing and improves the pellet formation rate.
04.
Mixing
The crushed powder goes into a mixer. This step determines how evenly nutrients are distributed in the final product. Imagine you have added trace elements and biological agents. If mixing is not thorough, some pellets may lack these ingredients. That would affect the fertilizer’s effectiveness.
05.
Pelletizing
No matter what raw material you use, granulation is the most important step. In this process, the uniform powder is squeezed between the ring die and press rollers. It is compressed and pushed out through the die holes. A cutter then slices it into pellets of even length.
06.
Cooling
Granulation generates heat from squeezing and friction. The fresh pellets come out hot. If you pack them immediately, the heat cannot escape. This can lead to mold and spoilage. Cooling removes the remaining heat and helps the pellets set quickly.
07.
Screening
This step may seem minor, but it affects the final appearance. If you use the fertilizer yourself, you might not care much about how it looks. But if you plan to sell it, appearance directly affects the price. Screening removes dust and broken pieces. Only the perfect pellets pass through.
08.
Packaging
You can transport fertilizer pellets in bulk or in bags. Bagging helps protect the pellets from damage. Weighing and packing are important steps. At this stage, you fill bags according to the set weight, seal them, and then store or ship them. This completes the full production process.
Core Equipment for Making Organic Fertilizer Pellets
Besides the organic fertilizer granulator machine, a full production line needs other auxiliary equipment. If you are thinking of building an organic fertilizer pellet production line, you may want to learn about these machines.
Raw Material Cleaning Machine
It is specially designed to clean ferromagnetic metal impurities from organic fertilizer raw materials. It can attract metal impurities such as iron filings, screws, and iron blocks by relying on the magnetic attraction of the raw materials, thus protecting other equipment.
Fertilizer Compost Compost Turner
The key equipment for the fermentation and maturation of organic fertilizer can turn over and toss the material piles, serving to provide nutrients, dissipate heat, and mix the materials. This process accelerates the high-temperature maturation of the raw materials and kills insect eggs and pathogens.
Organic Fertilizer Crushing Machine
It is used to break down and crush well-rotted organic fertilizer raw materials, whether it is high-moisture, coarse fiber manure, straw, fruit pomace, etc., and can be processed to output fine powder with a pellet size of less than 3mm.
Organic Fertilizer Mixer Machine
Its function is to uniformly stir and mix organic powders and trace elements. Most of them adopt a twin-shaft paddle structure, with two shafts rotating in opposite directions, resulting in a short mixing cycle and high uniformity.
Organic Fertilizer Cooler Machine
By utilizing the principle of countercurrent cooling, cold air is allowed to penetrate the organic fertilizer pellets from bottom to top, lowering their temperature and removing some moisture. This reduces the discharge temperature to room temperature and also increases the hardness of the pellets.
Organic Fertilizer Screening Machine
This is a commonly used piece of equipment in the production of organic fertilizer pellets. It usually adopts a multi-layer vibrating screen structure and uses high-frequency vibration to accurately separate qualified finished products that are plump and uniform in size, with a separation accuracy of up to 99.5%.
Organic Fertilizer Granulator Machine Advantages
RICHI organic fertilizer granulator machines have been delivered to over 140 countries and regions. They are widely used for processing different types of organic waste. Customers have given us good feedback. This is due to several key advantages.
Many organic materials are corrosive and abrasive. This puts high demands on the materials used in the organic fertilizer granulator machine. Our machine uses a ring die made of 42CrMo alloy steel. The surface is carburized and hardened. The hardness reaches HRC 58-62. This is more wear-resistant than ordinary stainless steel. It extends the machine’s service life.
Long Service Life
Our organic granular fertilizer making machine can handle many materials. These include fibrous materials like straw and sawdust, as well as wet, sticky materials like fruit pomace and coconut coir. You can adjust the parameters to get the ideal result. Simply change the ring die hole size and adjust the compression ratio from 1:10 to 1:18. This allows you to produce pellets from 4 to 12 mm in diameter. You can also control how dense the pellets are.
High Granulation Flexibility
Many customers care about reliable operation. Our machine frame is thickened for stable and low-vibration operation. If blockage or overload occurs, the safety pin breaks automatically. The limit switch triggers a shutdown. This protects the ring die, press rollers, and gearbox from damage. It also reduces repair costs.

FAQ
After reading all the above, do you have other questions? We have gathered some common questions. They may be helpful to you. You can also contact us directly for more specific and personalized advice.
Why do the pellets produced by the organic fertilizer pellet machine easily turn into powder?
→
This is usually linked to a few factors:
① The material moisture is not suitable. Being too dry or too wet both affect pellet quality.
② The grinding fineness is insufficient. If the raw material is not ground fine enough, the larger pellets will not bind well.
③ The press roller or ring die is worn. Worn key components reduce extrusion force.
What is the organic fertilizer granulator machine price?
→
The price of a RICHI organic granulator fertilizer machine ranges from USD 7,000 to USD 100,000. We cannot give an exact price directly.
