In today's organic fertilizer industry where high efficiency and low costs are key, the double roller press granulator stands out with its unique process, becoming the core equipment for upgrading production lines.
1.No Drying Needed, Forms Directly
Double roller extrusion uses physical rollers for cold molding. Raw materials are directly squeezed into granules under high pressure between the rollers. This skips the drying step, cutting energy use by 30-40% and significantly lowering production costs.
2.Continuous, High-Efficiency Production
The two rollers press synchronously at high speed. Single-machine output can reach 3-15 tons/hour (depending on model), without needing to stop for cooling. It runs continuously 24/7. It's especially good for lightweight materials like straw powder or humic acid.
3.High Granule Strength
High-pressure extrusion makes granules dense (1.2-1.5 g/cm³), hard, and resistant to crumbling. Transport loss is less than 2%, directly reducing rework costs.
Why Is It Better Suited for Organic Fertilizer Production Lines?
1.Extremely Adaptable to Raw Materials
Materials like livestock manure (moisture ≤25%), fibrous stuff (straw, rice husks), or sticky waste (sludge, mushroom residue) can all be processed. Plus, it doesn't need binding agents, simplifying the formula.
2.Small Footprint, Quick Payback
The machine is compact and flexible to install. It pays for itself in 6-8 months, making it the top choice for small-to-medium fertilizer plants.
3.Eco-Friendly, Zero Pollution
It runs fully enclosed–no dust, no exhaust gases. Easily passes environmental inspections.
In short, with its three big advantages–power, time, and labor savings–the double roller press granulator is becoming the best solution for organic fertilizer companies to cut costs and boost efficiency.
