Sludge Dewatering Screw Press Machine

Working Principle of Sludge Dewatering Screw Press Machine

• The Sludge Dewatering Screw Press operates on the principle of gradual compression and filtration:
• Slurry or sludge is fed into the inlet chamber.
• A slow-rotating screw shaft conveys the sludge forward.
• The filter rings / screen allow water to drain while retaining solids.
• Pressure increases progressively towards the discharge end.
• Dewatered sludge cake is discharged continuously.
• This design ensures stable dewatering, minimal clogging, and unattended operation.
