use
Screw conveying and pressing machine is suitable for grid slag treatment of urban sewage treatment plant, sewage pretreatment device in residential district, municipal rain/sewage pump station and water works, etc. It is mainly used with grid and other equipment to transport, press and dehydrate grid slag.

Structure and working principle
The equipment adopts the shaftless spiral, when the materials come into inlet from conveying press enter, rely on the rotation of the screw vane will slide material goes on, the u-shaped conveyor trough to the compaction area, squeezed the pipe and the discharging door against spring pressure, dehydrating grid slag crushing, forced open the gate of slag after dehydration pressure plate fall to junk car outside, The extruded seepage flows into the grid well through the backwater line.
