We often encounter problems such as insufficient high-frequency upper limit, insufficient high-frequency sensitivity, large peaks at high frequencies, or double peaks, and high-frequency sounds, which can be solved by the following five points.
1. Improve the high frequency upper limit by changing the shape of the pyramid bus.
2. Improve the high frequency curve by adjusting the cone material.
3. By changing the cone weight, slurry mode and thickness control. .
4. By adjusting the drain hole of the dehydration mold during papermaking.
5. Add a small arc near the hole in the cone.
