Double Roller Extrusion Granulator

A robust double-roller extrusion granulator engineered for high-efficiency cold granulation of a wide range of raw materials. The machine uses a two-roll extrusion principle to produce flat-round pellets with a controlled particle diameter of 3–10 mm and a granulation rate up to 85%.

Key features and benefits:

• High granulation rate: up to 85% for materials such as ammonium bicarbonate, ammonium chloride and monoammonium phosphate.
• No-drying, room-temperature, one-step molding process — eliminates the need for dryers and reduces energy consumption and operating costs.
• Environmentally friendly operation with no wastewater or waste gas emissions.
• Wide raw-material adaptability: suitable for compound fertilizer production and granulation of chemicals, pharmaceuticals (powdered intermediates), feed, coal, metallurgy and other powdered materials.
• Compact footprint and low capital investment — quick commissioning and rapid return on investment for small- to medium-scale production lines.
• Consistent pellet shape and size: produces flat, round composite granules with tight size control (3–10 mm).
• Power range: 11–22 kW (model- or capacity-dependent).

Typical buyers and use cases:

• Fertilizer manufacturers producing compound and nitrogen-based fertilizers.
• Chemical and pharmaceutical processors needing cold compaction granulation for moisture-sensitive powders.
• Feed producers, metallurgical plants, and coal-processing operations requiring pelletized products for handling and dosing.

Notes:

• Final capacity, roll size, and throughput depend on model configuration and the physical properties of the feed material. Discuss your target throughput, raw material characteristics, and desired pellet size with the supplier to confirm the correct machine specification.
