Double-Cutting Non-Wear Sludge Dewatering Press With SS 304 Double Screws Filter Cylinder

Product Description

Twin-Screws Wear-Free Sludge Dewatering Press

XF-SW series is a newly developed Sludge Dewatering Machine by PIONIERE, featuring a dual-screw design housed in a single cylinder. With externally driven moring rigns, the double-cutting action ensures stable, high-efficiency dewtering. The non-contact structure virtually eliminating abrasion and extending service life while reducing maintenance costs.
 

♦ Twin screws in one filter cylinder.
   Continuous shear and compression between the twin screws enable faster and more uniform sludge dewatering.

♦ Non-Contact & Low Wear
   Moving rigns driven by a gearmotor instead of by screw blades, which minimizing friction, reducing maintenance and
   extending service life.

♦ Self-Cleaning & Stabel Operation.
   Externally driven moving rings and self-cleaning filter mesh prevent clogging and ensure stable dewatering performance.

♦ 24/7 fully automatic operation, reducing labor costs.

 
Working Principle

The non-wearing screw press consists of fixed rings and moving rings that are stacked together, with two screw shafts passing through them to form a filtering chamber. The moving rings, driven by an external driving and guiding device, generates linear motion at its upper end and pendulum-like motion at its lower end, continuously offsetting with the fixed rings to keep the filter gap unblocked. Inside the chamber, the two screw shafts operate synchronously in opposite directions, and the sludge is gradually dewatered under the pushing and squeezing of the screw shafts.
