Product Description

screw press sludge dewatering machine

Working Principle

The main body of press filter sludge dewatering machine is made of multiple fixed annular plates and moveable annular plates with the screw shaft running through it. The front part is concentrating section and the ending part is dewatering section. It can concentrate and dewater sludge in one chamber. Sludge will be transported to the dewatering part after being concentrated in the thickening section.In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance with the block of the back platen. Then the volume decreases continuously, and the purpose of fully dewatering will be achieved.
