22kw Power Double Roller NPK Fertilizer Machine with 2.5-3.5 Ton Per Hour Capacity and Carbon Steel Construction

The Compound Fertilizer Granulator NPK Fertilizer Machine with Double Roller is an extrusion slip model granulator designed for efficient fertilizer production. This machine operates through a motor-driven system that transfers power through belts, pulleys, and reduction gears to drive dual rollers rotating in opposite directions for continuous mass production.

• No drying process required - room temperature granulation with single molding process
• Low investment with quick returns and excellent economic benefits
• Small power consumption with reliable operation and no waste discharge
• Stable operation with convenient maintenance and advanced process layout
• Wide raw material applicability for granulating compound fertilizer, medicine, chemical fertilizer, feed, coal, and metallurgical materials
• Capable of producing various concentrations and types including organic fertilizer, inorganic fertilizer, bio-organic fertilizer, and magnetic fertilizer
• Particularly effective for raw earth carbonate ammonium sulfate and compound fertilizer applications

The double roller compound fertilizer granulator machine represents extrusion granulator technology. Dry materials are compressed into hard, dense blocks under pressure during the extrusion process. These block materials are then crushed, screened, and granulated in the subsequent granulating process. The extrusion function removes air between particles and brings particles close enough to generate molecular interaction forces, forming granule hardness primarily through molecular attraction. Our double roller press machine enables continuous extruding granulation through positive-displacement technology.
