Automatic Sludge Dewatering Decanter Centrifuge with Touch Screen

Decanting can separate solid-liquid mixtures or mixtures of two immiscible liquids. This process involves carefully pouring a liquid from one container to another, making it effective for separating immiscible liquids such as oil and water.

• All parts directly touching material are made of stainless steel
• Continuous and automatic operation minimizes labor costs
• Two motor drive with adjustable bowl and screw speed via VFD
• Continuous spiral discharging with PLC control and touch screen operation
• Scroll conveyor coated with wearable alloy or welded with alloy plate (according to material characteristics and customer demand)
• Safety protections include: rotation rate detection, vibration protection, motor overload and overheat protection, scroll protection when zero differential speed occurs

The bowl and screw make high-speed rotation with a certain differential speed between them. The materials enter the bowl from the feed tube. Under centrifugal force, the liquid of higher specific weight accumulates on the bowl's inner walls and is discharged through the centripetal pump or overflow plate. Lighter liquids form an inner liquid ring, stick to heavy liquid surfaces, and discharge from the overflow channel. The spiral material pusher continuously pushes solids to the bowl's taper end where they discharge from the residue outlet after drying.

This horizontal, continuously working sedimentation centrifuge features continuous spiral discharging, ideal for sewage sludge dewatering and thickening.

• All material contact surfaces use high-quality stainless steel or duplex stainless steel
• Specially designed bowl and spirals press dewatered cake at conical end for high dryness
• Double motor with double frequency conversion and multi-stage planetary gear drive
• Real-time automatic adjustment of bowl/screw differential speed based on material characteristics
• Unique DC bus-powered design ensures strong spiral torque while reducing power consumption
• Comprehensive wear protection options including welded hard facing, spray coating, ceramic ports, and more
