Binder of Charcoal Briquetting - Weather Resistance

Weather resistance is one of the characteristics of high quality briquettes. Good charcoal briquettes have little deterioration after long exposure to the weather. Dense briquettes are better than porous ones in weather resistance.

 
During the briquetting process, the briquettes are liable to crack if the briquettes are insufficiently pressed, or are pressed too wet, or if the charcoal particles/powders are mixed improperly, or if the binder proportion is not appropriate.
 
Cracks of the briquettes allow the entrance of moisture which means cracks could result in rapid deterioration on exposure to the weather. Lignite briquettes for example, possess porous structure and water absorbing capacity, thus cannot stand long exposure to the weather. However, charcoal briquettes produced from coal of finely ground, with a dense arid polished surface, are more resistant to weather.
 

The binder Used for Charcoal Briquetting Must Be Insoluble in Water

 
The great obstacle to the successful use of sulphite-liquor residues, starch, and molasses as binders is their solubility. Feel free to contact us if you have any questions on coal/charcoal extruder for sale or briquetting binder.
