Four-roller Double-pressing Type Coal Briquette Press Machine

Specifications

Four-roller double-pressing type coal briquette press machine

Coal briquette press machine can supply higher pressure and higher density during production of briquettes; it’s mainly used in the briquettes making of various material, such as

Color and black metallic mine powder: Iron scale, Iron sludge, Precipitator dust, Iron concentrate, Raw material powder, Manganese ore fines, Silicomanganese alloy. Etc.

Coal : Coal powder, Coke powder, Slime peat, Middle coal, Lignite etc. 

Other material:
Charcoal powder, fireproof material, Desulfurization gypsum, Dolomite etc. 

Anyway, briquetting is the only one way to change the powdery material into briquettes which is suitable for transporting, in the meantime, this way also saves energy

Process Flow of 4TPH Coal Briquette Press Machine:

• Get raw material prepared: sieving, pulverizing the charcoal lumps/chunks or coal mateirals into fine powder.
• Get appropriate binder.
• Mixing process: mixing coal / charcoal powder with binders and some other additives if needed.
• Briquetting process/Extruding process: briquetting/extruding mixed charcoal powder into specific shape with charcoal making machine.
• Drying process: sun drying or automated tunnel type continuous drying
• Packing process: carton packing, gunny packing, paper packing.

This kind of coal briquette press machine has two larger rollers in a fixed position in the frame, the other two smaller rollers are moveable. As its named implied, it has four rollers and do twice pressing in production of briquettes, so the briquette is stronger and in higher density, the surface of briquettes is smoother.

Final Briquettes:
Shape: Can be round, pillow, oval.
Size: Changeable size 18mm-80mm, made according to clients requests.
