NPK fertilizer production line can produce various concentrations and types of compound fertilizers, including organic fertilizers, inorganic fertilizers, biological fertilizers, and magnetic fertilizers. This system is particularly effective for producing rare earths, potash, and ammonium bicarbonate series compound fertilizer granulation, filling technological gaps and achieving advanced levels in China.

This roller granulation system operates on an extrusion sliding model. The working principle involves: electric motor driving belts and pulleys, transmission to the drive shaft via reducer, synchronized operation through open gear and passive shaft. Material is fed from the hopper, extruded by rollers, and demolded to form granules.

• Lower investment with excellent economic returns
• Compact, scientifically designed complete fertilizer extrusion granulator system with advanced technologies
• No waste discharge, stable operation, easy maintenance and operation
• Direct dry powder extrusion to crushing screen studio, with finished pellets screened and separated, while material returns for mixing with new materials to enable continuous mass production
