Solving Double Disc Refiner Problems for Paper Mill
Our company provides a high-quality double disc refiner for your paper making line. This machine directly treats the fibers, but it often faces two main problems. The first issue is uneven wear. Because the two grinding zones work together, poor pulp distribution or pressure changes can make one side wear out much faster. This lowers pulp quality and machine stability. The second issue is tooth breakage and short life. Hard impurities like sand or metal can break the teeth. Running with a narrow gap or too much stress causes heat damage. Starting without pulp, also known as dry running, can quickly damage the double disc refiner.
To fix these problems, you need practical solutions. First, match the refiner plates to your working conditions. Choose the right material and tooth shape for your specific pulp. Second, optimize your running parameters. Keep the power, consistency, and pressure in a safe range to avoid high stress. Third, stop dry running. Make sure the grinding zone is full of pulp before you start the double disc refiner. Always keep the cooling water running well. Finally, consider using reversible plates. Some double disc refiner plates can be flipped over to extend their life. The table below shows a simple guide to these solutions:
| Problem Type | Main Cause | Solution |
|---|---|---|
| Uneven Wear | Uneven pulp feed or pressure changes | Improve pulp distribution |
| Tooth Breakage | Hard impurities or dry running | Use pre-screens and avoid dry starts |
| Short Plate Life | Too much stress or poor cooling | Optimize parameters and check cooling water |
| High Wear Cost | Fixed plate design | Use reversible and self-sharpening plates |
