Horizontal Screw Conveyor decanter centrifuge,used in drilling mud solids control system

PRLog (Press Release) - Mar 13, 2010 -
Belowed some infomations about GN decanter centrifuge.

Operational Principle of Horizontal Screw Conveyor decanter centrifuge

Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor. The product Stillage is fed into the bowl through a stationary inlet tube and is then smoothly accelerated by an inlet rotor. Centrifugal force immediately makes the solids build up on the wall of the bowl.

The conveyor rotates in the same direction as the bowl, but at a lower speed, thus moving the solids towards the conical end of the bowl. The solids leave the bowl through the solids discharge openings into the casing.


Separation takes place throughout the entire length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.

3   Feature：

1．Made from German HUMBOLDT Technology.


2．It adopts large extruder L/D=3,high speed, large torque differential gear system, large extruder extends the remain time for clearing and dehydration; high rotation speed with large centrifugal force, small speed differential gear can less the agitation to the material, extend the remain time for dehydration, so improve the effectiveness for separation of concentration, dehydration and cleaning for the sludge.

3．It adopts Mechanical Differential.

4. initial velocity adjustment range：10、20、30r/min；

5．Impellor welding W2C-65%，Thickness 2～3mm, resistance to abrasion

6．contact segment with material is made of 16MNR;drum material:16MNR;screw material:16MNR;cover material:AISI304,backflow type, used for dehydration.

7. Bearing imported from SKF or FAG

8. Brand motor, Explosion proof Grade:IP55.

9．Drive belt: SAMSUNG
