Why honeycomb coal persists
The honeycomb shape burns evenly, fits traditional stoves, and uses cheap coal fines — which is why millions of households still buy it daily. For fuel entrepreneurs, the punch press is a low-investment machine with a proven market: one machine, local coal fines, and distribution to shops and stalls.
Key parameters to define
- Local briquette diameter and hole count your customers expect.
- Coal fines source, clay binder ratio and local practice.
- Target pieces per day and working hours.
- Manual feeding or conveyor automation level.
- Drying space or dryer for finished briquettes.
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Press type | Mechanical punch press | By briquette size |
| Briquette diameter | Interchangeable molds | 100–220 mm |
| Output | By mold and cycle | 2,000–8,000 pcs/day |
| Power | Electric motor | 5.5–11 kW |
Ranges are indicative. Output depends on briquette size and operator feeding rhythm.
