LWS 3 Phase Decanter Centrifuge
 

Separation takes place in a horizontal bowl equipped with a scroll conveyor. The process material is fed into the bowl through a stationary inlet tube and is smoothly accelerated in the accelerate chamber. Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl.

 

LWS series three phase decant centrifuge is used for solid-liquid-liquid separation, namely one kind of solid phase (with largest specific gravity ) and two kind of immiscible liquid phase with different density. The conveyor rotates in the same direction as the bowl, but at a different speed, the material is fed into the bowl through a stationary feed pipe. Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl, while two liquid phases forming light liquid phase layer and heavy liquid phase layer. Scroll conveys the solids towards the conical end of the bow, and out of centrifuge from solid discharge port. The light liquid phase then is discharged out continuously through the overflow port at the large end of the bowl, and the heavy liquid phase will be discharged out through the centrifugal pump large end of the bowl, thus realizing the three-phase separation.

LWS 3 Phase Decanter Centrifuge
 
Main applications

LW series decanter centrifuge is a horizontal centrifuge with continuous feeding and continuous discharging. It has two-phase (solid-liquid) separation and three-phase (solid-liquid-liquid) separation.

Applications:

Industrial and municipal wastewater treatment
Oil & gas drilling mud/fluid control
Washing, classification and dewatering of amylum and starch
Mycelium separation from zymotic fluid of antibiotic
Dewatering of soybean and wheat protein
Dewatering of fish power and fish meet
Dewatering of grains

Clarification and extraction of fruit juice
Clarification and purification for animal and vegetable oil
Production and extraction of olive oil, palm oil, avocado oil
Separation and purification for coal tar
Grading of kaolin and graphite
Classification and dewatering for dyestuff and pigment
Float wash of extractive coal and dewatering of coal mud
Classification and dewatering for minerals

Optional system
 

Hydraulic scroll driving system

LWS 3 Phase Decanter Centrifuge
 

The hydraulic conveyor driving is a closed driving system, including the centrifuge bowl and conveyor. It is independent from the bowl driving. The hydraulic conveyor driving is different from other mechanical conveyor driving system which relies on bowl rotating to generate differential speed. The hydraulic driving device is directly mounted on the conveyor assembly, and is driven by hydraulic pump aggregate. Therefore it is independent from the bowl driving system.

LWS 3 Phase Decanter Centrifuge
 

Operating principle

The hydraulic conveyor gearbox is connected with the bowl of the decanter centrifuge, both of them rotates in high speed. The spline shaft on the gearbox rotor is connected with the conveyor, and rotates in different speed driven by the high pressure oil, that's we call the differential speed. The conveyor gearbox is connected with the hydraulic pump by flexible hose, so there is no need of gearbox between the bowl and conveyor. Conveyor torque gives pressure to the hydraulic system. With the action of such pressure, the different speed can by adjusted by adjusting the oil supply and flow rate.
