We can make cow dung pellets by extrusion method. And a typical extrusion line includes solid–liquid separator → compost turner/fermentation system → crusher → screener → batching & mixing system → extrusion granulator (flat‑die pellet mill or double‑roller extruder) → dryer → cooler → screener → coating machine → automatic packing scale → palletizer. You cost for setting up this line depends on your target output.

Are you curious about whether we could make cow dung pellets by <a href=”https://www.granulationproject.com/product/roller-compaction-dry-granulation-machine/” target=”_blank” rel=”noopener noreferrer”>extrusion method</a>? The answer is yes. In fact, extrusion pelleting works well for fibrous materials like cow manure, especially when you use a flat-die pellet mill or a double-roller extrusion granulator. These machines handle the fibrous nature of cow dung effectively. However, stable cow dung fertilizer pellet quality depends on proper moisture control and well-fermented (mature) material.
How it’s done: fresh cow dung is first dewatered to reduce moisture (typically below 60%), then aerobically fermented/composted until fully matured. Après cela, the material is crushed and screened, and additives (such as straw powder, humic acid, or binders if needed) are blended while adjusting moisture to about 25–35% for flat-die pelleting, or about 20% for double-roller extrusion. Suivant, the material is formed into pellets/granules by a flat-die pellet mill or compacted into granules by a double-roller extrusion granulator. The pellets/granules are then dried, cooled, screened (oversize/undersize returned), optionally coated for anti-caking, and finally weighed and packed.
What equipment do you need for making cow dung pellets by extrusion method？
Are you wondering what equipment do you need for <a href=”https://www.granulationproject.com/product/cow-dung-fertilizer-manufacturing/” target=”_blank” rel=”noopener noreferrer”>making cow dung pellets</a> by extrusion method? A typical extrusion line to make that runs like this: solid–liquid separator → compost turner/fermentation system → crusher → screener → batching & mixing system → extrusion granulator (flat‑die pellet mill or double‑roller extruder) → dryer → cooler → screener → coating machine → automatic packing scale → palletizer.
The separator removes excess water and cuts drying cost. Fermentation stabilizes manure, reduces odor, and kills <a href=”https://en.wikipedia.org/wiki/Pathogen” target=”_blank” rel=”noopener noreferrer”>pathogens</a> and weed seeds. The crusher breaks lumps and improves pellet forming. The screener removes stones, fibers, and oversize. Batching and mixing add fillers/binders (straw powder, humic acid, etc.) and adjust moisture for extrusion. The flat‑die or double‑roller unit compacts material into pellets/granules with good density. The dryer lowers moisture to safe storage level, and the cooler hardens pellets and prevents caking. The second screener returns fines and oversized to rework. Coating improves anti‑caking and appearance. Emballage, then palletizing, finish the shipment.
How much does it cost to set up a fertilizer production line for making cow dung pellets by extrusion method?
Do you want to know how much a cow dung <a href=”https://www.granulationproject.com/product/fertilizer-pellet-machine/” target=”_blank” rel=”noopener noreferrer”>fertilizer production line</a> costs? Here is a quick budget guide based on different capacities. A 1-2 t/h line (6,000-12,000 t/year) costs $110,000. A 3 t/h line (18,000 t/year) costs $140,000. A 5 t/h line (30,000 t/year) costs $190,000. And a 10 t/h line (60,000 t/year) costs $360,000. These are complete line prices. And you’re welcomed to contact us for a precise quote for your project.
