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.

◇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 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.
◇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
