NPK Compound Fertilizer Granulator with High Granulation Rate >98% and Room Temperature Granulation for Wide Raw Material Adaptability

This fertilizer production equipment features an attractive appearance, simple operation, low energy consumption, long service life, and high granulation rate. As China's most advanced compound fertilizer granulation equipment, it represents state-of-the-art technology with nationwide product distribution.

• No drying process required - room temperature granulation with single-step molding
• Low investment with quick returns and excellent economic benefits
• Reliable operation with no waste discharge, stable performance, and easy maintenance
• Advanced technology with reasonable process layout and low production costs
• Wide raw material compatibility including compound fertilizer, pharmaceuticals, chemicals, feed, coal, metallurgy, and more
• Capable of producing various concentrations including organic, inorganic, biological, magnetic fertilizers
• Specialized for rare earth, ammonium bicarbonate, and ammonium sulfate compound fertilizer granulation

The double roller granulator operates on an extrusion-slip model. Electric motors drive belts and pulleys to power the driving shaft through a reducer, with synchronized gears enabling opposite work between driving and driven shafts.

Material enters the granulating room from the hopper, undergoes roll extrusion molding, mold release, and ball formation, then moves via chain conveyor to the screening studio where finished pieces are separated from the mixture. The remaining material returns for reprocessing with new material inputs.

Key working components include:

• Squeezing and pressing section: Materials are compressed into high-density, hard cakes under pressure
• Granulating section: Pressed cakes are crushed and screened into small granules

The roller extrusion granulator demonstrates wide raw material adaptability including DAP, SSP, gypsum, sheep manure, cow manure, chicken manure, pig manure, bentonite, and various animal waste materials. It achieves high production rates for diverse fertilizer types including organic, inorganic, and compound fertilizers, with special capability for rare earth fertilizer, potash fertilizer, and ammonium bicarbonate series.

When integrated into complete fertilizer production lines, this equipment eliminates the need for rotary dryers.
