Double roller press granulators turn organic waste into treasure

Double roller press granulators offer a unique advantage: they transform loose, wet, hard-to-handle organic waste into high-value commercial organic fertilizer pellets, without needing drying and using low-temperature forming. This opens a golden pathway for resource recycling.

1.Saves Drying Energy

Double roller press granulators directly handle wet materials with 20%-40% moisture (like fresh manure, biogas residue, or sludge). No expensive, high-energy drying equipment is needed upfront.

2.Low-Temperature Extrusion

They use powerful mechanical pressure (not heat) to force the material into shape at room or low temperatures. This fully preserves organic matter activity, beneficial microorganisms, and volatile nutrients (like nitrogen), ensuring the final product's fertilizer efficiency far surpasses high-temperature granulation.

3.Efficient Forming

Precision-meshed roller dies apply hundreds of tons of pressure, producing hard, low-dust (≤5% powdering), uniform, smooth oblate or pillow-shaped pellets.

4.Cuts Costs and Boosts Efficiency

Granulation reduces volume by 30%-60%, significantly lowering storage and transport costs. Pellet fertilizer is also easier to apply mechanically, improving efficiency and saving labor.

5.Pollution-Free Production

The closed extrusion process of the double roller press granulator produces almost no dust. The resulting dense pellets pose no leachate leakage risk. The process prevents odor spread.

Wide Applications

1.Livestock Manure: Directly granulates wet manure (chicken, pig, cattle, etc.), solving issues of drying space and foul odor.

2.Municipal Sludge: Quickly forms stabilized sludge for safe resource recovery.

3.Food/Kitchen Waste: Efficiently converts pre-treated organic solid residues.

4.Composted Material: Upgrades powdery compost into commercial pellets, enhancing quality and price.
