Swing Screw Press Dewatering

Swing screw press dewatering machine is the special dehydrator for the industry was developed on the basis of the previous generation machine. We adopted the structure of no shaft fretting between the disc and the screw axis to improve the service life of screw axis and dynamic fixed ring. And according to the different characteristics of the industry to optimize design, the machine is operated under the rigid working conditions, which greatly reduce the cost of equipment operation and maintenance management. The machine is widely used in municipal sewage treatment engineering and food, starch, oil, pharmaceutical, chemical, paper, leather and other industries of water treatment system and high concentration slurry extraction.

The spiral axis moves slightly from one side to the other at a constant speed along with the rotating disc, and the spiral axis has a decreasing pitch and the dewatering space becomes narrower. When the material is transported from the concentrated part to the dewatering part, the internal pressure is gradually increased due to the back pressure plate, so that the sludge is fully dehydrated and discharged in the shape of mud cake under strong pressure.
