Product Features and Applications: coal dust briquetting machine vs sawdust brick maker machine

 

 

Finished Product Material and Density: Charcoal vs. Wood Fuel

The Wood Chip Brick Making Machine produces wood-based block fuel (wood chip bricks) with a density of 1.0-1.2 g/cm³. It retains the original fibrous structure of wood chips, contains no binders, and burns odorlessly. The Wood Chip Charcoal Extruder produces machine-made charcoal with a density of 1.2-1.5 g/cm³. Made of charcoal, some lower-priced models may produce a slight odor when burning due to the addition of binders. Its higher density makes it more resistant to burning.

 

 

 

Wood chip bricks (finished product from briquetting machines) have a calorific value of 4200-4800 kcal/kg and a burning time of approximately 2-3 hours per brick. They are suitable for small boilers, rural heating, and restaurant heating, but produce a relatively large amount of ash after combustion. Machine-made charcoal (finished product from extruders) has a calorific value of 6000-7000 kcal/kg and a burning time of 4-6 hours per brick. It produces less ash and has a stronger flame, making it suitable for barbecue restaurants, high-end catering, and industrial high-temperature heating. Its added value is far higher than that of wood chip bricks.

 

Subsequent Processing and Application Extension: Different Paths

Wood chip bricks (finished product from briquetting machines) can be used directly as primary fuel or further processed into machine-made charcoal in a carbonization furnace, increasing added value. Charcoal briquette extruders, on the other hand, are already finished products (machine-made charcoal) and require no further processing. They can be sold or exported directly, and some can be further processed into activated carbon (requiring additional equipment). Their application scenarios are more geared towards the high-end market.

 

Storage and Transportation: Differences in Stability

Wood chip bricks (finished product from a husk briquette machine) are highly hygroscopic, requiring proper moisture-proofing during storage, with a transportation loss rate of approximately 5%-8%. Machine-made charcoal (finished product from an extruder) is less hygroscopic, offering better storage stability, with a transportation loss rate controllable to below 3%. It also boasts a higher calorific value per unit volume, resulting in more advantageous transportation costs, making it suitable for long-distance transportation and cross-border sales.
