Piston press vs screw press
Two machines make biomass fuel: the screw extruder (rod machine) and the piston briquette press. The piston type hammers material into thick 70–80 mm logs at lower temperature, handling fibrous straw and husk that challenge screw machines, and producing the chunky fuel industrial boilers prefer.
Key parameters to define
- Residue type: straw, rice husk, sawdust, bagasse or mixed.
- Moisture of your material (10–15% working window).
- Target log diameter for your boiler or stove buyers.
- Daily residue supply and briquette output target.
- Whether carbonization follows (charcoal logs sell higher).
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Press type | Mechanical piston punch | By material fiber |
| Log diameter | Interchangeable dies | 70–90 mm |
| Throughput | Model series | 300 kg/h – 1.5 t/h |
| Power | Main motor | 22–55 kW |
Ranges are indicative. Fibrous residues need pre-crushing and moisture control.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Material test | Was your residue briquetted, with density results? |
| Moisture window | What moisture range does rated capacity assume? |
| Wear | Punch and die life on your material, replacement cost? |
| Pre-processing | Is crushing/drying equipment included for your residue? |
| Density | Log density and calorific value demonstrated? |
