Making organic fertilizer needs shaping. Unshaped powder is hard to use. You need the right machine.
A twin roller extrusion granulator shapes organic fertilizer. It presses material into granules. This makes the fertilizer easy to handle and apply. It solves the powder problem. Choosing the right granulator is important. Different machines work differently. Twin roller granulators have specific uses. They offer certain benefits. This machine can be a good choice.
What is a Twin Roller Extrusion Granulator? How Does It Shape Organic Fertilizer?
Your organic material is powder. How do you make it a granule? You need a special process.
A twin roller extrusion granulator uses pressure. It compacts powder into a solid sheet. Then it breaks the sheet into granules. This process does not need water or heat.
Twin Roller Granulator Parts
Feeding System: Puts material into the machine.
Twin Rollers: Press the material into shapes.
Crushing System: Breaks the pressed sheet into granules.
Screener sorts granules by size. This simple process makes powder into usable granules. It is effective for many organic materials.
What Are the Advantages of Twin Roller Extrusion Granulators Compared to Traditional Equipment?
You have options for granulating organic fertilizer. Why pick this one? What makes it stand out? Twin roller granulators offer specific benefits. They work without drying. They are good for simple production lines. They save energy and space compared to some other methods.

Are My Organic Fertilizer Materials (Chicken Manure, Cow Manure, Straw, etc.) Suitable for Twin Roller Extrusion Granulators?
You have specific raw materials. Will this machine work for you? Not all materials are the same. Twin roller granulators work best with certain materials. They need material that compacts well under pressure. The moisture content is important.
The suitability depends on the material’s properties. Moisture content is critical. Too much moisture makes the material sticky and hard to compact properly. Too little moisture makes it crumbly. The ideal moisture range for twin roller granulation is usually between 10% and 20%.
This can vary a bit depending on the material type. It is important to match the machine to the material. Some materials are better for disc granulation. Some are better for drum granulation. Some are best for extrusion granulation. We have experience with many types of organic waste. We can help you determine the best process. The goal is to make good quality granules. The right machine makes this possible.
Suitable Material Types (After Proper Pre-treatment)
Composted Chicken Manure
Composted Cow Manure
Composted Pig Manure
Composted Municipal Sludge
Food Waste Residues
Agricultural Residues (Straw, Stalks – often mixed with other materials)
Some Industrial Organic Wastes
Certain Chemical Raw Materials
Material Properties Needed
Moisture: 10% – 20% (approx.)
Particle Size: Fine powder/small particles
Compaction Ability: Material must stick under pressure We evaluate your material properties. Then we recommend the best machine type.
The granulator is one part. It does not work alone. What other machines do you need? A twin roller granulator fits into a system. It needs machines before it and after it.
You need a full set of machines. The process starts with raw material. It needs to be prepared. First, fermentation is important for organic waste like manure. You need fermentation equipment. My company makes compost turning machines. We have trough type, crawler type, and wheel type turners.
These machines help the material ferment. After fermentation, the material might be lumpy. It needs crushing. You need a crusher. We have different crushers for different materials. Vertical crushers and horizontal crushers are common. After crushing, the material might need drying to the right moisture level for the granulator.
If it is too wet, you need a dryer. If it is too dry, you might need a mixer with a small amount of water, but typically the twin roller works best with lower moisture, avoiding drying. The crushed material then feeds into the twin roller granulator. The granulator makes the sheet/flake.
Then a crusher breaks the sheet into granules. These granules are not all the same size. You need a screener. A screening machine separates the granules. Large ones and small ones are sent back for re-processing. The good ones go to the next step. If you want rounder granules, you might add a polishing machine after screening.
Finally, the finished granules need packaging. You need a packaging machine. This machine weighs the granules and puts them in bags. My company offers all these machines. We offer complete production lines. We design the whole system. We install it.
We train your staff. We provide service. A typical line includes feeding, crushing, mixing (if needed), granulation, screening, and packaging. Sometimes drying is included before crushing or after granulation, but with twin roller, drying after granulation is usually not needed.
The specific machines needed depend on your raw material and desired final product. We customize the line for you.
Typical Supporting Equipment
Fermentation/Composting Equipment: (e.g., Compost Turners) – Needed for raw organic waste
Crushing Machine: (e.g., Vertical or Horizontal Crusher) – Needed after fermentation
Mixing Machine: (Optional, for blending materials or adjusting moisture slightly)
Twin Roller Extrusion Granulator: The core machine.
Screening Machine: (e.g., Vibrating Screen) – Needed after granulation
Polishing Machine: (Optional, for rounding granules)
Packaging Machine: (Automatic or Semi-automatic) – Needed for final product
Conveyors: (Belt conveyors, Bucket elevators) – Connect all machines We provide a complete solution. We help you build the whole factory.
