Double-string shaft non-wear dehydrator, especially useful for high viscosity and high concentration of sewage; Structure and working principle: The use of twin screw mutual movement and extrusion principle, start-up, self-cleaning and process stability is good, no shaft;

The floating ring adopts an external drive mode, does not contact with the spiral shaft, has no wear, no wearing parts, and increases the shear force to further dehydrate the sludge.
