Bowl Drive System

The reliable and excellent operation needs good cooperation of bowl drive and conveyor drive. Shanghai Centrifuge Institute researches good drive combination, which can be recommended as best design to suit different applications.

Drive Technology

This is controlled by the drive system of the conveyor. The drive system of the conveyor can measure real-time the solid content inside the bowl and adjust automatically, solid discharge torque automatically compensated.

In order to achieve best dewatering effect when flow rate or character of sludge changes, the solid content inside the bowl should be continuously controlled.

Control the Staying Time of Solid

In the conical part of the bowl wall, the sludge is pressed by specially designed double direction pressing effect. The specially designed conveyor produces axial pressing force and water comes out of the tiny holes of the sludge.

Double-direction Pressing Stage

Conveyor pushes the solid toward the discharge end. The sludge is further pressed by centrifugal force and the water comes out of the small holes of the sludge.

Pressing Stage

The flocculants sediments inside the bowl under centrifugal force, the clear liquid flows out of the weir an the end of the bowl.

Clarifying Stage

Sludge and chemical mixes in the specially designed feed chamber and accelerates together. This prepares the sludge for best separation.

Mixing and Accelerating Stage

High dryness decanter can use limit space to fit together different stages of separation.

Working Procedure

Super hard abrasive-resistant material W2C-65% is spay welded on solid discharge port, feed port and conveyor blade. The thickness if 2~3 mm. Comparing to tiles, it has better duration and needs no replacement. This prolongs the operation life.

Wide adjustment range of starting differential speed: the differential speed is adjusted within the range from 0 to 20 rpm.

Hydraulic differential speed system is adopted. The output torque is greater (
