PRODUCTS OVERVIEW

 

What's the LW Decanter Centrifuge

 

LW Sedimentation Centrifuge is a horizontal, continuously working and continuously spiral discharging sedimentation centrifuge. It is used in a variety or industries for separating all kinds of solid liquid suspension, defecating liquid phase with graded grains, and dehydrating sludge. 2 phase Decanter Centrifuge:  After entering into the high-speed turning drum, the solid-phase particles in the mixed liquid run and settle on the drum wallunder the action of greatest centrifugal force; the light liquid settles at the innermost place of the drum under minimum centrifugal force; same as the drum's turning direction, a screw feeder also turns at a high speed, and a constant speed difference is generated by the differential mechanism, then the liquid will be discharged by the liquid outlet. 3 phase Decanter Centrifuge:  Principle of threephase decanter centrifuges is as shown in the above figure. The substance to be separated is fed by the feeding tube into the accelerating cavity of the spiral conveyor, then enters high speed running drum wall. As the light liquid, heavy liquid and insoluble solid contained in the substance have different specific gravities, the three materials are subject to varied centrifugal forces: the insoluble solid settles into the inner wall (outside) due to its highest specific gravity and subject to maximum centrifugal force; the light liquid settles maximum far away from the inner wall (outside) due to its lowest specific gravity and subject to minimum centrifugal force; and heavy liquid settles in the middle place. The insoluble solid is discharged from the solid discharge port by a spiral feeder which has relative differential speed with the drum; and the light and heavy liquids are then separated by different structures inside the machine wherein the heavy liquid is discharged by the centripetal pump, and the light liquid is discharged via the force of gravity, thus the purpose of three phase separation is achieved.

Liquid-Solid 2-Phase Decanter Centrifuge

-The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedmentationof the solids on the wall of the bowl.

--Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor.

Liquid-Liquid-Solid 3-phases Decanter Centrifuge

--The conveyor rotates in the same(adverse) direction as the bowl, but slightly slower(faster), thus moving the solids towards the concial end of the bowl. The cake leaves the bowl through the solids discharge openings into casting.

--The separation process runs through the bowl entire cylindrical section, clarified liquid is separated by adjustable overflow plate.

 

Producrs Advantage

1.  LARGE PROCESSING CAPACITY OF ONE EQUIPMENT: When the solid particle size is 0.007mm, the treatment capacity can reach 40m3/ h, and the parts material is made of high-quality corrosion stainless steel.

2 . COMPACT STRUCTURE AND SMALL SPACE-OCCUPANCY  :  The design is suspension type, low center of gravity type and mobile type, can be combined accoring to user requirements.

 

3. EQUIPPED WITH MULTIPLE SAGETY PROTECTION DEVICES:  including over-vibratation protection, bearing temperature detection, screw conveyor torque protection rotating and differential speed detection, as well as nitrogen-filled explosion-proof protection, motr overload and over heat protection. Equipment control system have ordinary type and flameproof type.

4. JG type rubber shock absorber requires no anchor bolts.

 

 

PRODUCT SPECIFICATIONS

DESIGN FEATURES

 

Material

All contact with the material are made of high quality stainless steel, or duplex stainless steel. Bowl body all centrifugal casting, to ensure the durability and reliability of the equipment.

 

Bowl and screw

In order to ensure a high dryness cake, specially designed bowl and spirals are pressed against the dewatered cake at the concial end of the bowl in a high-pressure, two-way manner to minimize the moisture of the cake..

Drive system

The machine uses double motor double frequency conversion, and with multi-stage planetary gear drive. The difference in speed between the bowl and the screw can be automatically adjusted by the control system in real time based on the characteristics of

the raw material and the user's requirements. At the same time unique DC bus-powered design, to ensure a strong spiral torque, while greatly reducing power consumption. In addition to include full hydraulic drive, including a variety of drive options for 

the user to chosse. 

Lubrication system

In addition to the traditional manual grease lubrication, optional automatic grease lubrication(or thin oil lubrication) to maximize the main bowl bearing and screw bearing for real-time lubrication, significantly improve the bearing, and then even the whole machine durability and reliability.

Control system

The system adopts SIEMENS PLC + HMI by default, fully integrating the key points including speed, differential, current, torque, vibration and so on.

Wear protection

A wide range of wear protection are available, including welded hard facing or spray coating, ceramic port, Zn carbide tiles, chilled hard mental portcastings, etc. all wear protection elements, except welded hard facings or spray coatings, are field replaceable.
