Reasons for the Fracture of Charcoal Produced by Briquette Machine

The fracture of charcoal produced by briquette machine is common, especially for people who just engaged in producing charcoal industry. However, the reasons that cause the fracture of charcoal are different in different conditions. In the following content, we will make a summary on the basis of our factory’s years of professional experience. The structural integrity of the briquette is affected by the size of particles, moisture, content of lignin and cellulose. As we know, lignin contained in biomass materials can enhance the bonding effect of briquette during the preheating of the material. A higher lignin content with a small particle size and low moisture would achieve a better bonding effect. In general, the fractures on the surface are probably caused by the irregular size of particles.

1. Semi-finished charcoal needs high density. The higher the density of charcoal, the better the quality of carbonized charcoal.

2. Elegant design of kiln with the volume of 2.7*1.4*1.6 or above. If the volume is not big enough that the kiln would be damaged by fire inevitably.

3. The seal of kiln body prevents the semi-finished charcoal and the kiln from turning off due to the air leakage. If you use the charcoal furnace, you’d better seal the welding-seams around the furnace ( the mud is pretty good).

4. The carbonizing process can not be too fast to maximize the discharge of humidity;

5. It is important to master the changing curve of carbonization and the technicians should have good judgment of the color and flavors of the smoke.

6. The moisture content of charcoal should be lower, because high moisture content would lead to many problems in firing and excessive energy will be needed for drying, and the quality of combustion would be affected as well.

7. The ash content should be less than 4%, because biomass with high ash content mostly composed of impurities, which have low fusion temperature that would lead to an increment in the material.
