Screw press sludge dewatering machine  


Configuration principle:


The screw type sludge dewatering machine consists of fixed ring and moving ring and 

screw shaft is throughout in it as the filter unit.  



Dewatering principle:


The sludge is conveyed to the dewatering zone after the gravity thickening , during the process 

of advancing, screw pitch of screw shaft becomes narrower and narrower and under the stop 

function of back pressing board, the very large  internal pressure is generated and the volume 

shrinks continually, so dehydration purpose is attained eventually.
