Product Description
 
 

LW Decanter Centrifuge
 

Labyrinth seal is used for both bowl ends of LW standard type decanter centrifuge, simple and convenient, after separation, the solid phase is conveyed to the solid discharge port by scroll conveyor, and discharged out of centrifuge under centrifugal force caused by high speed rotation; while the liquid phase drains out under gravity and centrifugal force through the overflow plate. This series decanter centrifuge features easily operation, continuous and stable running, and wide application scope.

Operating principle

LW 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.
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.

Main 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

 
Main Features
Vertical base design and symmetrical arrangement of motor and bowl assembly, that ensures stable operation and less vibration.
Main parts such as the bowl and conveyor are made of corrosion-resistant stainless steel or duplex steel, offering high maximum bowl speed and high centrifugal force.
Dual motor drive makes bowl speed and conveyor speed adjustable.
Screw conveyor flights tiled or lined with ceramic, tungsten carbide, or other hard alloys.
Optional planetary gearbox and hydraulic gearbox, offering wide range of differential speed adjustment.
Multiple safety protection: bowl speed and differential speed detection, over-vibration protection, motor overload and overheat protection, bearing temperature monitoring, conveyor torque protection and gas-tight explosion-proof protection.
JG type rubber vibration isolator, no need of anchor bolts.
 
Wear protection

Solid discharge port

1.Tungsten carbide or ceramic bushing
2.Simple structure and easily replacement
3.LOW maintenance cost

Optional system
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.

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. 

 

Main features

No gear driving device required
No damage to the parts due to overload
Free of torque vibration (fluttering)
Direct readable torque and differential speed △n
△n independent from bowl speed
Minimum moisture content of sludge

High clarification of liquid phase
Power for solid conveying varying from solid loads
Dewatering varying from changes in △n
"Constant" moisture content of sludge
Non-sensitive to feeding quantity, minimize blockage 
Safety pin design ensuring safe operation
