Belt Press vs. Chamber Filter Press: Why Ceramic Factories Should Switch?
Belt Press vs. Chamber Filter Press: Why Ceramic Factories Should Switch?
Ten years ago, the Belt Filter Press was popular because it runs continuously. However, for the Ceramic and Stone industry, the Belt Press has a fatal flaw: Pressure is too low.
A Belt Press relies on the tension of two belts to squeeze sludge. It cannot generate high pressure. The result is a “soupy” sludge cake with moisture content often above 40%.
Why Porvoo High-Pressure Chamber Press Wins?
1. Drier Cake (Lower Moisture):
Our Chamber Press uses a hydraulic station to exert 1.6 to 2.0 MPa of pressure. It forces water out of the finest particles. The cake is so dry you can break it by hand.
2. Clearer Filtrate (Clean Water):
Belt presses often leak sludge from the sides, making the recycled water dirty. Chamber presses are sealed. The water coming out is crystal clear and ready for reuse in polishing lines.
3. Lower Operating Cost:
Belt presses require constant washing of the belts (wasting water) and frequent belt replacement (expensive). Chamber filter cloths last much longer.
Conclusion
If you are still using a Belt Press, you are wasting money on higher disposal fees and wet sludge handling. The trend in 2026 is High Pressure.
