sludge dewatering screwpress

What are the difference between Dewlink's Swingmill and another non-wearing screw press?

The so called non-wearing screw press uses two external drive rod to power the screw but there are flaws.  

It is easy to bend under pressure because the main screw is only supported by the external drive rod at both end of the screw.  

The movement of the rings is limited by a forward motion or in a swing motion.  The rings cannot cut into the gaps of the screw, only around the edges.  It is ineffective at water filtration and inefficient at pushing the sludge forward.
