When only high pressure works
Standard briquette presses rely on moisture and binder to bind particles. Quicklime hydrates, metal powders oxidize, and many chemical fines cannot tolerate either. Dry powder machines use much higher roller pressure — often hydraulic — to compact material purely by force, producing briquettes for steel mills, chemical plants and metallurgical furnaces.
Key parameters to define
- Material chemistry and why wet pressing is excluded.
- Particle size distribution and flowability of the powder.
- Target briquette strength for handling and furnace charging.
- Throughput per hour at required pressure setting.
- Dust control and explosion protection for fine powders.
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Pressure system | Hydraulic constant-pressure | High-pressure class |
| Roller diameter | Model series | 520–1000 mm |
| Throughput | By material and density | 1–15 t/h |
| Briquette shape | Pillow, oval, custom | Interchangeable molds |
Ranges are indicative. Dry pressing requires a material test — not all powders briquette binder-free.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Material test | Was your powder pressed on a pilot machine, with strength data? |
| Pressure | Line pressure rating and is it adjustable for your material? |
| Wear | Roller skin material and life on abrasive powder? |
| Safety | Dust explosion protection for your material class? |
| Feeding | Force-feeding system matched to powder flowability? |
