Biomass pelletizing with 96%+ forming rate and 15% lower energy consumption.
Conditioned sawdust, straw and other biomass enter the vertical ring die chamber, where rollers press the material through the die holes. Under pressure and friction it compresses into dense 6–12 mm pellets, cut to length by knives. The vertical layout keeps the center of gravity low and feeding even; with our self-developed forming chamber the pelletizing rate stays above 96% with about 15% lower energy use.
Where this machine fits in a production line:
Don't shop by catalogue capacity alone — confirm these three things first:
Wood sawdust uses standard 6–8 mm compression-ratio dies; straw and rice husk need higher compression ratios and finer pre-grinding.
Model 470: 0.8–1 t/h, 580: 1.5–2 t/h, 700: 2.5–3 t/h, 850: 3–4 t/h — choose with 10–20% headroom over your target.
Keep infeed moisture at 12%–18%; too wet needs drying first, too dry needs conditioning. A trial run nails the parameters in one go.
| Model | Power(kW) | Output(t/h) | Pellet Size(mm) | Dimensions(m) | Weight(t) |
|---|---|---|---|---|---|
| 470 | 75 | 0.8–1 | φ6–φ12 | 2 × 1 × 1.7 | 4 |
| 580 | 132 | 1.5–2 | φ6–φ12 | 2.3 × 1.2 × 2 | 5 |
| 700 | 160 | 2.5–3 | φ6–φ12 | 2.6 × 1.3 × 2 | 7.5 |
| 850 | 250 | 3–4 | φ6–φ12 | 3 × 1.4 × 2.4 | 11 |

The questions buyers ask most before choosing a model.
12%–18% is ideal. Material that is too wet must be dried first; material that is too dry needs conditioning. We recommend a trial run with your actual raw material before choosing a model.
It depends on your raw material. Fine, correctly dried material can start with a single pellet mill; logs and straw need chipping, crushing or drying first. We configure based on your material, not on what we want to sell.
Catalogue figures are standard-condition references. Real output depends on material type, moisture and particle size. We calculate capacity with your actual material — and can prove it in a trial run.
They are normal wear parts, typically several hundred to a thousand operating hours depending on material cleanliness. Wear parts are in stock and can be shipped within 48 hours.
Real feedback from project sites and follow-up visits.
“The whole line has been running normally in the plant — you can see the output stability with your own eyes.”
“They ran a trial with our material before recommending a model — and talked us out of the wrong one. That earned our trust.”
“Installation to first discharge in three days, with their engineer on site for commissioning.”
Prepare the following before we talk — we can identify the machine and process combination much faster.
