Working Principle
Force-water concurrent; Thin-layer dewatering; Moderate press; Extension of the dewatering path
It has solved several technical problems of other similar sludge dewatering equipment including belt presses, centrifuge machines,
plate-and-frame filter press have, which are frequent clogging, low concentration sludge / oil sludge treatment failure, high
energy consumption and complicated operation etc

Thickening:
When the shaft is driven by the screw, moving rings around the shaft move up and down relatively. Most water is
pressed out from the thickening zone and fall down to the filtrate tank for gravity.
pressed out from the thickening zone and fall down to the filtrate tank for gravity.
Dewatering:
The thickened sludge moves forward continuously from the thickening zone towards the dewatering zone. With the pitch
of the screw shaft thread getting narrower and narrower, the pressure in the filter chamber increases higher and higher. In
addition to the pressure generated by the back-pressure plate, the sludge is greatly pressed and dryer sludge cakes produce.

Self-cleaning:
The moving rings rotates continuously up and down under the pushing of the running screw shaft while the gaps
between the fixed rings and moving rings are cleaned to prevent from clogging that happens frequently for traditional dewatering
equipment.
