Heavy Duty Abrasion Resistant Double Roller Extrusion Granulator with Replaceable Roller Shell for NPK Fertilizer Plant

This heavy duty double roller extrusion granulator is specially engineered for processing highly abrasive mineral powders such as phosphate rock, potash, bentonite and rare earth powder in NPK fertilizer plants. The abrasion resistant design ensures stable granulation performance and extended equipment service life.

• Abrasion Resistant Rollers: Roller shells made of high chromium alloy and 65Mn steel, hardened surface withstands severe wear from abrasive minerals.
• Replaceable Roller Shell: Quick-change wear parts reduce maintenance cost and downtime to a minimum.
• Heavy Duty Structure: Reinforced frame and bearings support continuous high-pressure compaction operation.
• Dry Extrusion Process: No drying needed, suitable for binderless compaction of mineral powders.
• Stable Granule Quality: Uniform high-density granules with consistent size for compound fertilizer production.
• Low Maintenance: Simple structure and accessible wear parts keep upkeep simple and cost low.
