Double Roller Granulator Machine Factory | Expert in Dry Granulation Technology

Welcome to our Double Roller Granulator Machine Factory, where we specialize in engineering robust and efficient double roller extrusion granulator systems. As a leader in dry granulating machine technology, we provide the ideal solution for a wide range of fertilizer production applications, from NPK fertilizer to specialized nutrient pellets. If you are planning an industrial fertilizer granulation plant and seek a cost-effective, reliable method, our double roller granulator is the answer.

What is a Double Roller Extrusion Granulator?
A double roller extrusion granulator, also known as a roller press or double roller granulator, is a cornerstone of dry granulation technology. Unlike traditional wet granulation methods that require liquid binders and subsequent drying, this machine forms fertilizer pellets through pure mechanical pressure.

The process is straightforward yet highly effective: dry, finely powdered raw materials are fed between two synchronized, counter-rotating rollers. Under immense pressure, the particles are compacted into a solid sheet. This sheet is then crushed and screened to produce uniform, irregularly shaped compound fertilizer granules. This method is renowned for its simplicity and high efficiency, making our dobule roller granulator a preferred choice for modern fertilizer factory operations.

Key Advantages of Our Double Roller Granulator
Dry Process, No Drying Required: The most significant benefit. It eliminates the need for expensive and energy-intensive drying ovens, drastically reducing your plant's energy consumption and setup cost.

• High Granulation Rate: Achieves a granulation rate of over 90%, minimizing raw material loss and reprocessing.
• Versatility in Raw Materials: Our NPK pellet making machine can handle a vast array of materials, making it more than just a compound fertilizer granulation tool. It is perfectly suited for processing salts like zinc sulfate, ammonium sulfate, ammonium bicarbonate, and magnesium sulfate without causing decomposition.
• Low Maintenance & Robust Design: Built with high-wear-resistant materials, the machine is durable and designed for continuous operation with minimal downtime.
• Environmentally Friendly: With no liquid involved, there is no risk of water pollution or the need for complex effluent treatment systems.

Wide-Ranging Applications in Fertilizer Production
The versatility of our double roller granulator makes it indispensable across various fertilizer sectors:

• NPK Fertilizer Production: As a highly efficient NPK pellet making machine, it can press blended powder of Nitrogen (N), Phosphorus (P), and Potassium (K) sources into strong pellets.
• Specialty & Micro-Nutrient Fertilizers: It is the ideal machine for incorporating nutrients like zinc sulfate and magnesium sulfate into granules without chemical degradation.
• Organic-Mineral Compound Fertilizers: While primarily for inorganic materials, it can be used to create compound fertilizers by blending organic powder with mineral nutrients.
• Ammonium-Based Fertilizers: It can effectively granulate ammonium bicarbonate and ammonium sulfate, which are sensitive to heat and moisture.

Integrating the Roller Press into Your Fertilizer Production Line
In an industrial fertilizer granulation plant, the double roller granulator serves as the core of the dry fertilizer production line. A typical layout includes:

• Raw Material Batching & Crushing: Ensuring a fine, uniform powder.
• Mixing: Blending various powder materials to a homogenous mixture.
• Granulation: The heart of the process, using our roller press.
• Screening & Recycling: Separating on-size pellets and recycling fines back to the process.
• Packaging: Weighing and bagging the final fertilizer pellet product.
