LW Series 2-Phase Decanter Centrifuge for Industrial Sludge Dewatering

Can you centrifuge salt water?
Centrifuges use the force of gravity to affect the separation of solids from liquids. Salt dissolves in water to form a solution. The centrifugal force exerted by a centrifuge separates immiscible phases such as sand from water but not miscible phases such as salt in water.

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.

• 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
• The scroll conveyor was 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 in a high-pressure, two-way manner to minimize moisture content
• Double motor double frequency conversion with multi-stage planetary gear drive
• Wide range of wear protection options available
