Industry news
A coal and charcoal briquetting machine processes fine coal dust or carbonized biomass powder into solid briquettes. By using pressure and a binder (like cornstarch), it maximizes fuel value and reduces waste. These machines range from $2,320 to $3,680 depending on the production scale.
How the Briquetting Process Works
To produce high-quality, dense briquettes without cracks, you need to follow a four-step process:
- Crushing: Raw material (lump charcoal or coal) must be crushed into a fine powder, ideally under 3 mm to 5 mm in size.
- Mixing: The dry powder is mixed thoroughly with liquid water and a binder (e.g., 3% to 5% food-grade starch) so every particle is evenly coated.
- Briquetting: The damp, mixed material is fed into the machine. Different types of equipment (such as screw extruders or roller presses) compact the material into shapes like pillows, hexagons, or squares.
- Drying: Fresh briquettes are very fragile and contain up to 25% moisture. They must be dried in a well-ventilated room until moisture drops below 5% to yield solid, usable fuel.
Types of Machines Available
- Screw Extruders: Uses a propulsion shaft to push mixed material through a mold. Excellent for making long charcoal sticks, barbecue pellets, or hexagonal/square logs (with or without a center hole).
- Roller Press Machines: Features dual rollers with distinct indentations used primarily to press coal or charcoal powder into pillow or ball-shaped briquettes.
- Honeycomb Briquette Press: An older, specialized vertical press that shapes material into classic cylinder “honeycomb” briquettes used widely in household stoves in certain regions.
If you’re planning a production line, tell me:
- What is your raw material (e.g., coconut shell, wood charcoal, anthracite coal)?
- What shape and size do you want to produce?
- What is your target production capacity (e.g., kg/hour or tonnes/day)?
