This extrusion granulator machine adopts normal-temperature dry granulation technology, which can directly process powdery organic raw materials into solid cylindrical fertilizer particles without a drying procedure. It is a core pelletizing equipment for organic fertilizer production lines. The machine runs stably with a compact structure, and the finished pellets feature high density and good hardness, making them resistant to breakage during storage and transportation. It is well matched with other fertilizer processing equipment to form a complete fertilizer manufacturing system.

• Normal-temperature dry extrusion granulation requires no drying, greatly reducing energy consumption and production costs.
• Special mould made of wear-resistant alloy steel offers a long service life and stable granulating effect.
• Produces uniform cylindrical pellets with high strength, good appearance, and a low breakage rate.
• Simple and compact structure allows convenient operation, easy inspection, and straightforward daily maintenance.
• Flexible adaptability makes it suitable for many kinds of powdery organic raw materials used in fertilizer production.
• Low failure rate supports continuous, long-time industrial production.

Powdery raw materials with proper moisture enter the granulating chamber evenly. Under the continuous squeezing force from the rotating pressing roller, the materials are extruded through the holes on the mould to form cylindrical strips. The cutting device then cuts the strips into uniform cylindrical pellets. The entire granulation process is completed at room temperature without adding extra binders.

This machine is widely used for the granulation of chicken manure, cow dung, pig manure, sheep manure, compost, straw powder, and other organic raw materials. It is well suited for small and medium organic fertilizer plants, livestock and poultry farms, waste resource recycling projects, and as supporting equipment in complete organic fertilizer production lines.
