The compound fertilizer granulator roller press pellet machine is designed for efficient fertilizer production through dry granulation technology.

The compound fertilizer granulator is used for processing various materials including:

• Filling particles, pigments, detergents, and catalysts
• Barium carbonate, fertilizers, silica, and inorganic salts
• Chloroisocyanuric acid, bleaching powder, pesticides, and oxides
• Industrial recycling dust materials: iron, lead, zinc, aluminum dust
• Converter dust, grinding dust, and other industrial byproducts

Material is forced compression molding by mechanical pressure without adding any wetting agent, ensuring product purity. The granulator features short process flow, low energy consumption, and high output capacity.

The double roller compound fertilizer granulator machine represents extrusion granulator technology. Dry materials are compressed into hard, dense blocks under pressure during the extruding process. These block materials are then crushed, screened, and granulated in the subsequent granulating process.

Extrusion functions to remove air between particles and bring particles close enough to create interaction forces. Particle hardness in roller compaction granulation is primarily formed due to molecular attraction forces. Our double roller press machine enables continuous extruding granulation through positive-displacement technology.

The double roller compound fertilizer granulator machine is utilized in 30,000 t/y compound fertilizer production lines and other manufacturing processes, including:

• Capsule filling particles, pigments, detergents, and catalysts
• Fertilizer, inorganic salts, calcium hypochlorite, and pesticides
• Oxides and various chemical compounds
• Industrial dust recovery materials: foundry dust, lead, zinc, aluminum dust
• Converter dust, grinding dust, and other industrial particulates
