(screw press sludge dewatering machine)
Modern screw press systems achieve 65-80% dry solid content through controlled mechanical pressure gradients. The helical shaft design rotates at 2-5 RPM, generating 0.3-1.2 MPa axial force for continuous dewatering. Unlike centrifugal models, these machines maintain 30% lower power consumption while processing 15-100 m³/hr sludge volumes.
