Complete Fertilizer Granulation Plant with Double Roller Extrusion Granulator System

The Double Roller Extrusion Granulator, also known as a Dry Granulation Machine or Roll Press Compactor, is an advanced industrial equipment designed for transforming fine powders into dense, uniform granules without the need for liquid binders. This machine utilizes the principle of Roll Press Compaction, where two synchronized, counter-rotating rollers apply extreme mechanical pressure to the raw material, forcing it through precisely designed molds (roll surfaces). The resulting product is sheet-like material that is then broken down and screened into uniform granules.

This Granulation Equipment is widely recognized for its efficiency in Material Densification, making it a preferred choice in industries such as fertilizer production, chemical processing, and mineral agglomeration. It is a cornerstone of modern Continuous Granulation Processes, offering a clean, economical, and scalable solution for Powder to Granules conversion.

• Dry Granulation Process: Produces granules without adding moisture or liquid binders, eliminating the need for subsequent drying steps.
• High Pressure Roller Compaction: Equipped with robust rollers and powerful hydraulic/spring-pressure system for hard, low-moisture granules.
• Excellent Material Densification: Increases bulk density of raw materials, improving storage and transportation efficiency.
• Continuous and Automated Operation: Designed for high throughput with stable output quality and minimal operator intervention.
• Versatility and Adaptability: Processes various materials including fertilizers, chemicals, and minerals with customizable granule size/shape.
• Environmentally Friendly: Closed system minimizes dust pollution; dry process avoids wastewater generation.
• Low Maintenance and Robust Construction: High-wear-resistant materials ensure long service life and reduced downtime.

The Double Roller Extrusion Granulator is a versatile machine with extensive applications across multiple industries:

• Fertilizer Granulation: Producing high-quality compound fertilizers, NPK fertilizers, and organic-inorganic compound fertilizers.
• Chemical Granulation: Processing pigments, dyes, resins, pesticides, and insecticides to improve flowability.
• Mineral and Metal Industry: Agglomerating metal powders, coal fines, and various ores for improved handling.
• Pharmaceutical and Food Industry: Dry granulation for powder formulations requiring improved compression characteristics.
• Other Industries: Production of ceramics, refractories, and recycling of industrial by-products.

The working process of the Double Roller Extrusion Granulator is a continuous mechanical cycle:

1. Feeding: Raw powder material is fed uniformly into the granulator's hopper.
2. Compaction Zone: Material enters the gap between two counter-rotating rollers.
3. High-Pressure Extrusion: Rollers exert extreme pressure to compact material into solid sheets.
4. Formation of Sheet/Ribbon: Compacted material exits as thin, dense sheet with specific patterns.
5. Crushing and Sizing: Sheet is broken down into fragments and screened for uniform granules.
6. Recycling: Fines and oversized particles are recycled back to the feeding system.
7. Final Product Output: Uniformly sized granules are discharged as final product.

The two-roll extrusion granulator efficiently produces high-quality granules without binders, balancing production efficiency, cost-effectiveness, and environmental sustainability. For enhanced granule quality, it can be used with a spheroidizing machine for spherical shaping and polishing, or integrated into a complete automated granulation production line.
