What can be processed by the double roll pelletizer?

A double roller extrusion granulator can process many materials. It works well for organic fertilizers, compound fertilizers, and chemical powders. It gives you dense, uniform granules for diverse needs.

What exactly is a double roller extrusion granulator, is it some kind of magic equipment?

Is choosing a granulator a headache? Do you wonder what this machine even does? Let’s make it simple.
A double roller extrusion granulator makes powder into granules. It presses material between two rollers. This process forms solid pieces without needing much water.

Basic Working Principle

• Material feeds into the hopper.
• Two counter-rotating rollers pull material in.
• Rollers apply high pressure.
• Powder compacts into a sheet.
• Sheet is broken into granules.
• Granules are screened to size.

Key Components

• Feeding System: Ensures material enters the rollers steadily.
• Extrusion Rollers: The core part, applies pressure, has specific patterns.
• Crushing/Flaking Mechanism: Breaks the compacted sheet.
• Screening System: Separates product by size.
• Recycle System: Sends off-spec material back.
  This machine works mechanically. It uses force to create granules. There is no drying step needed usually. This saves energy.

Which materials are suitable for a double roller extrusion granulator? Is your material suitable?

Many powders work with a double roller granulator. It is good for materials that compact well under pressure. Organic waste, chemical compounds, and certain fertilizers are common examples.
I see many types of materials successfully granulated with this method. The key factors are the material’s ability to compact and its moisture content. This machine handles materials with low moisture, typically under 10-15%. Some materials might need a small amount of binder. Other materials compact naturally under pressure. This machine is excellent for materials sensitive to heat or moisture. It avoids heat damage from drying. It avoids chemical reactions from water. We can process materials like animal manure compost, crop residues, and municipal sludge. These are common organic fertilizer raw materials.

Suitable Material Examples

Besides organic fertilizer, what can double roller extrusion granulators process?

Thinking this machine is just for fertilizer? Wondering if it fits your non-fertilizer product? You might be surprised by its capabilities.
This granulator works for many industries. It processes chemical powders, mineral dusts, and even some animal feed additives. Its dry process is key for these uses.
I have seen our double roller granulators used in many different settings. My customers process more than just organic waste or compound fertilizer. Many chemical manufacturers use this technology. This improves safety and processing efficiency. Mineral processing plants use it for dust control or product enhancement. Fine mineral powders can be difficult to transport and use. Granulating them makes them manageable. Some pharmaceutical or food ingredients might also be granulated this way. This happens if they are powder and require dry processing. Animal feed ingredients or additives that are fine powders can be densified. Granulation makes them easier to mix into feed formulations. It reduces dust.

Still hesitating? Look at the success stories, how did they do it?

Many companies use double roller granulators successfully. They process diverse materials. They achieve high-quality granules. Their success shows the machine’s reliability and effectiveness for B2B operations.
I have seen our machines solve real problems for customers. A large farm wanted to process their own cow manure compost for sale. They needed a simple, reliable machine. They chose our compact double roller line. They now produce granular organic fertilizer on-site. This turned waste into revenue. They reduced disposal costs. They created a valuable product for local farmers. Another customer, a chemical plant, needed to granulate a fine salt powder. The powder was dusty and caused handling issues. They also needed a specific granule strength. We provided a double roller granulator with customized rollers. The machine produced strong, low-dust granules. This improved their plant’s air quality. It also made their product more marketable. These stories show how this machine solves real-world B2B challenges.

These examples are typical. They show the machine’s value in different B2B scenarios. It offers efficiency and product quality.

Double roller extrusion granulators are versatile machines. They process organic, compound, and chemical powders effectively. They offer a dry, efficient granulation solution for many industries.
