Product Description

Spare part of Screw Type Sludge Dewatering Machine : Screw Shaft




Component diagram 





Working principle

As equipment starts running, sludge flows into the filter cylinder and moves forward to sludge cake outlet under the thrust from screw shaft. 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.




Reasons of wear 

♦ Friction between sediment and screw shaft

♦ Friction between moving rings and screw shaft blade

♦ The inner pressure during dewatering

♦ SS304 material

♦ Edge charmfer design

♦ Surface hardening coating
