Screw Type Sludge Dewatering Machine for Chemical Industr

Working Principle:

As equipment starts running, sludge flows into the filter cylinder and moves forward to sludge cake outlet under the thrust from screwshaft. The whole filter cylinder is composed of fixed rings, moving rings and shaft. The first two sections are thickening zone, last two are dewatering zone, The space between screw blades gets more and more narrower, which means the inner pressure gradually gets bigger. Under this pressure, liquid is squeezed out from the sludge and leaks from the small gaps between rings. And the left dry solid is pushed to the sludge cake outlet.
