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.

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
◇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.
◇Optionla 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.
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
