The dehydration process of Screw Press Machine is divided into two stages. In the first stage, the screw conveyor is used for dehydration.
In the second stage, a material blocking device is used for dehydration. When the material enters the discharge section of the screw conveyor, the screw conveyor will apply axial thrust to the material, pushing it out of the discharge port. At the same time, the material blocking device pressurized by the air pressure device will apply counter force to the pushed material, forming a two-stage dehydration extrusion force for the material.
