The coal fines opportunity
Coal mining and handling generate 10–20% fines that clog yards and sell at a discount. Briquetting converts this liability into product: pillow-shaped briquettes for household stoves, large ovals for industrial boilers, custom shapes for specific furnaces. Buyers are typically coal yards, mining companies and fuel distributors.
Key parameters to define
- Fines source: raw coal, washed coal or lignite.
- Moisture and ash of your fines supply.
- Binder plan: starch, molasses or bentonite by market acceptance.
- Target shape and burn requirements of your buyers.
- Daily fines volume and briquette output target.
Typical configuration ranges
| Item | Common options | Indicative range |
|---|---|---|
| Press type | Roller press, medium-high pressure | By coal plasticity |
| Throughput | Model series | 2–30 t/h |
| Briquette size | 25–60 mm pillow/oval standard | Custom molds available |
| Drying | Mesh belt dryer downstream | Matched to press output |
Ranges are indicative. Lignite and high-ash fines need specific pressure and binder plans.
What a quotation should clarify
| Quotation area | Questions to record |
|---|---|
| Fines test | Was your coal fines sample briquetted and strength-tested? |
| Binder cost | Binder type and cost per tonne of briquettes? |
| Strength | Drop and crush strength after drying? |
| Wear | Roller skin life on abrasive coal, replacement cost? |
| Scope | Crusher, mixer, feeder, dryer included in the line? |
