Product Introduction
Volute Sludge Dewatering is a new type of solid-liquid separation device,which uses the screw extrusion principle. It reaches the goal of extrusion dewatering sludge by the powerful extrusion pressure of changing the screw diameter and distance, and the tiny spacing between moveable annular plates and fixed annular plates.

Structure Principle
The main body of Volute Sludge Dewatering in made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is thickening departmant and the ending part is dewatering department. It can thicken and dewater sludge in one box, and has taken place of the traditional filter clothes and centrifugal filtration method for its diatinctive filter model.

Dewatering Principle
Sludge will be transported to the dewatering department after being thickened in the thickening department. In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance, and the back platen clogging. Then the volume decreasea continuously, and the purpose of fully dewatering will be achieved.
