Besides, it is suitable for waste water treatment of electric power plant sludge, printing and dyeing sludge, paper manufacture sludge.
Working Principle:
Two Phases Separation Principle:
The feed suspension is introduced through an inlet pipe into the feed zone of the conveyor where it is accelerated and directed into the interior of the bowl. The settled solids are conveyed axially towards the small end of the bowl by means of the screw conveyor, which rotates at a slightly different speed than the bowl. On the way to the discharge ports the solids are lifted out of the pond up along the dry beach. The solids are finally discharged from the bowl through the discharge ports into the collecting chamber of the casing that surrounds the bowl. From there the solids are removed by gravity through the outlet funnel. The liquid phase forming a hollow cylinder due to the centrifugal force, and flows towards the large end of the bowl. There the liquid overflows adjustable plate dams into the centrate chamber of the casing and is discharged by gravity.
Three Phases Separation Principle:
The light liquid phase is discharged into the casing through radial holes in the large end hub. The heavy liquid phase is discharged through axial holes in the large end hub. The liquid radius for the light liquid phase is smaller than the radius for the heavy liquid phase. The liquid level is controlled by plate dams. In order to prevent the light liquid phase from leaving the bowl through the heavy liquid phase outlet, a separating plate is placed on the inside of the large end hub. The heavy liquid phase has to pass under the separating plate before being discharged into the casing. The liquid radius for the heavy liquid phase is controlled by plate dams. The solids are discharged in the normal way.

Working principle
The drum and the spiral feeder rotate in the same direction but with a certain speed difference; the material is led into the feeding spiral inner cylinder via the feeding pipe and, after speeding pipe and, after speeding up, enters the drum;under the action of the centrifugal force field, the relatively heavier solid-phase material deposits on the drum wall forming the residue layer; the solid-phase residue is continuously pushed by the spiral feeder to the conic end of the drum and, after dehydration in the drying area, is discharged out of the machine.The machine is capable of continuous feeding, separating, dehydrating and discharging under full-speed running.
