6. Moving Disk Type Thickening & Dewatering Equipment
Principle
The opening between the fixed & moving plate, screw pitch narrows gradually from the
concerntration part to the dehydration section.
When the screw and the moving plate are rotated sludge is discharged through the opening
between the fixed and moving plate generation internal pressure at the dehydration section
which in turn performs dehydration with internal pressure gradually increased by the back
pressure valve
During the operation the moving plate continues eccentric movement to prevention clogs in
the opening and discharges sludge with high-concerntration dehydration fluid through
Function of clogging prevention by moving disk
