Stainless Steel 2-Phase Decanter Centrifuge for Sludge Dewatering

What can you separate with a centrifuge?
In science, a centrifuge is a device that helps separate components of a mixture through the use of centrifugal force, by spinning. A centrifuge is a tool that helps separate particles based on their size, density, or shape. Centrifuges can be used to isolate blood particles from whole blood samples, for example.

The three-phase working principle
The bowl and screw make high-speed rotation with a certain differential speed between them. The materials will enter the bowl from the feed tube. Under the action of centrifugal force field, the liquid of the high specific weight will accumulate on the inner walls if the bowl, and be discharged through the centripetal pump or overflow plate. The liquids of low specific weight will form an inner liquid ring, stick to the surfaces of heavy liquids, and be discharged from the overflow channel. Under the action of the spiral material pusher, the solids in the materials will be continuously pushed to the taper end of the bowl and discharged from the residue outlet after going trough the drying area.

LW series 2phase sedimentation decanter centrifuge is a horizontal, continuously working and continuously spiral discharging sedimentation centrifuge. It can be used for the sewage sludge dewatering and thickening.

• All parts directly touch to material are made of stainless steel
• Continuous and automatic operation can minimize labor costs
• Two motor drive, adjustable bowl and screw speed via VFD
• Continuous spiral discharging, PLC control and screen touch operation
• The scroll conveyor was coated with wearable alloy or welded with alloy plate (according to the material characteristics and customer demand)
• Safety protection: rotation rate detection over, vibration protection, motor overload and overheat protection, protection for scroll when zero differential speed occurs
• All contact with the material are made of high quality stainless steel, or duplex stainless steel
• Specially designed bowl and spirals are pressed against the dewatered cake at the conical end of the bowl in a high-pressure, two way manner to minimize the moisture content of the cake
• Double motor double frequency conversion with multi-stage planetary gear drive
• Wide range of wear protection options available

Huading Separator has been at the forefront in the field of centrifugal separation technology for more than 60 years, established in 1954, is the leader in mechanical separating technology in China.
