If your biomass briquette machine isn't producing good briquettes, don't worry, it might be due to the following reasons. Below are some practical troubleshooting and solutions to help you quickly resolve the issue:

1.Raw Material Issues:

• Incorrect Moisture Content:

  • Materials that are too dry or too wet can affect the quality of the briquettes. Too dry and they won't compact well; too wet and they'll easily crumble.
  • Solution: Squeeze a handful of material; if it forms a ball without sticking to your hand, it's about right. Moisture content should generally be controlled between 8%-12%.

• Large Particle Size:

  • Materials with large or uneven particle sizes can result in loose briquettes.
  • Solution: Use a crusher to break down the material, ensuring uniform particle size, typically below 5mm.

• Unsuitable Materials:

  • Some materials (like sawdust, straw) have poor natural adhesion and are difficult to compact.
  • Solution: Add a binder, such as starch, molasses, or clay, to help the material stick together. (Refer to the binder section for more details.)

• Too Many Impurities:

  • Impurities like stones or soil in the material can affect briquette quality.
  • Solution: Clean the material thoroughly before processing to remove impurities.

• Incorrect Material Ratio:

  • An inappropriate ratio of different materials can also lead to poor briquette quality.
  • Solution: Experiment with different material ratios to find the optimal combination. (If you encounter difficulties, please contact us.)

2.Binder Issues

• Insufficient Binder:

  • If the material itself has poor adhesion and insufficient binder is added, the briquettes may fall apart.
  • Solution: Increase the proportion of binder, such as starch or molasses.

• Unsuitable Binder:

  • Some binders may not be compatible with your material.
  • Solution: Try different binders to find the most suitable one. (Refer to the binder section for more details.)

3.Machine Settings Issues (How to set up your biomass briquette machine?)

• Insufficient Pressure:

  • Too little pressure will result in loose, easily crumbled briquettes.
  • Solution: Increase the machine's pressure to ensure the briquettes are compact.

• Incorrect Temperature:

  • Some materials (like wood chips) require heating to compact properly; insufficient temperature can affect quality.
  • Solution:Appropriate temperature, 300-350 degrees roughly. In actual production, we should appropriately adjust temperature according to the degree of burnt surface of briquettes.

• Mold Issues:

  • Worn or incorrectly sized molds can result in irregularly shaped briquettes.
  • Solution: Inspect the mold; replace it if it's severely worn, and ensure the mold size is suitable for your material.

4.Machine Maintenance Issues (How to repair a biomass screw conveyor?)

• Worn Parts:

  • Over time, parts like the screw and mold can wear out, affecting briquette quality.
  • Solution: Regularly inspect the machine and replace worn parts promptly.

• Insufficient Lubrication:

  • Excessive friction during machine operation can lead to uneven compression.
  • Solution: Regularly lubricate the machine, especially the moving parts.

5.Operational Issues

• Uneven Feeding:

  • Adding too much or too little material at once can affect briquette quality.
  • Solution: Feed material evenly; avoid overloading or letting the machine run empty.

• Incorrect Machine Setup:

  • Incorrect machine settings will inevitably lead to poor briquette quality.
  • Solution: Carefully read the manual to ensure the machine is set up correctly. (If you encounter difficulties, please contact us for guidance on operating your biomass briquette machine.)

6.Machine Overload

• Overloading the Machine:

  • Continuously overloading the machine will degrade briquette quality.
  • Solution: Avoid running the machine at full capacity all the time; give it appropriate rest periods.
