Briquetting machine molds are core components that directly determine the shape and density of finished briquettes. Their service life significantly impacts production efficiency and operational costs. Extending mold longevity requires a combination of material optimization, proper operation, regular maintenance and targeted technical adjustments.
Optimize Raw Material Preparation
- Process raw materials to achieve uniform particle size through crushing and screening.
- Control moisture content—avoid overly wet or overly dry materials.
- Add appropriate binders or lubricants for difficult‑to‑form materials.
- Eliminate hard contaminants and abrasive impurities.
Standardize Operational Practices
- Maintain a steady and consistent feeding rate to prevent uneven distribution.
- Avoid sudden load changes during operation to prevent impact damage.
- Ensure the machine is fully warmed up before formal production.
- Do not force materials into the mold to avoid deformation or cracking.
Implement Regular Maintenance
- Clean the mold cavity regularly to remove residual material.
- Use soft tools for cleaning to avoid damaging the precision surface.
- Apply a protective coating or anti‑rust agent during idle periods.
- Check for signs of wear (surface roughness, dimensional changes) for timely repair.
Adjust and Calibrate Properly
- Ensure correct installation and alignment with other components (e.g., rollers).
- Adjust compression pressure to match material properties—avoid over‑compression.
- Use mold repair techniques (surface plating, welding) to restore worn surfaces.
- Choose high‑quality molds made of wear‑resistant materials.
By systematically applying these practical measures, operators can significantly reduce mold wear, prevent premature damage, and ensure sustained production efficiency with lower operational costs.
