Why briquetting unlocks powder value
Coal fines, charcoal dust, iron powder and lime are cheap or free because powder is hard to handle. A roller press squeezes material between two matched rollers with pocket molds, producing uniform briquettes that sell as fuel, furnace feed or chemical raw material — often at several times the powder price.
Key parameters to define
- Material type, particle size and moisture content.
- Whether binder is needed and acceptable to your end user.
- Target briquette shape, size and strength requirement.
- Throughput per hour and daily tonnage target.
- Whether drying follows (wet briquettes need a dryer).
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Pressure class | Standard, high-pressure (dry powder) | By material plasticity |
| Roller diameter | Model series | 290–1000 mm |
| Throughput | By material and shape | 1–30 t/h |
| Shapes | Pillow, oval, square, custom molds | Interchangeable rollers |
Ranges are indicative. Briquetting success depends on material test and moisture control.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Material test | Has your exact powder been tested, with strength results? |
| Binder | Is binder required, and does your market accept it? |
| Strength | Drop strength and water resistance of finished briquettes? |
| Wear | Roller skin life on your material and replacement cost? |
| Line scope | Mixer, feeder, dryer and conveyors included? |
