Stainless Steel Decanter Centrifuge Separator for Plant Extraction

Mixed liquids and particles are fed into the spinning bowl via an inlet. By adjusting the acceleration of the rotor, the centrifuge can hold the solid particles (or "solid phase") to the rotor wall while permitting the liquids (i.e., the "liquid phase") to flow out.

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 of 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 through the drying area.

LW series 2-phase 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 touching material are made of stainless steel
• Continuous and automatic operation minimizes labor costs
• Two motor drive, adjustable bowl and screw speed via VFD
• Continuous spiral discharging, PLC control and screen touch operation
• Scroll conveyor coated with wearable alloy or welded with alloy plate (according to material characteristics and customer demand)
• Safety protection: rotation rate detection, vibration protection, motor overload and overheat protection, protection for scroll when zero differential speed occurs
• Specially designed bowl and spirals press against the dewatered cake at the conical end of the bowl in a high-pressure, two way manner to minimize moisture content
• Double motor double frequency conversion with multi-stage planetary gear drive for real-time adjustment
• Wide range of wear protection options including welded hard facing, spray coating, ceramic port, zinc carbide tiles, and chilled hard metal portcastings

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.
