 Structure of Volute Dewatering Press                 


1.The main part of the dehydrator is a filter device that a screw runs through the stacked

   fixed rings and moving ring.


2.The small gaps between fixed rings and moving ring can filter the sludge, and the

   lumenbetween screw and rings is filled with polymer grains. The moving ring transfers

   the sludge to the end of the machine with pressure and extrudes sludge cakes.

3.The running of the screw drives the moving ring to clean the gaps and avoid jam.



The rings are cut by laser cutter with 0.1mm admissible error, and polished one by one to ensure the smooth surface. Smooth& Strength


Automatic spray system. Start time, working time and water supply volume are adjustable.
