Lw250*1000n Sludge Dewatering Decanter Centrifuge - High Capacity Tricanter Centrifuge
I. Decanter Centrifuge Introduction
The horizontal spiral discharge settling centrifuge operates on the principle of centrifugal settling for continuous solid-liquid separation. The solid phase is discharged by a spiral mechanism, making it an efficient and continuous solid-liquid separation equipment with the following features:
1. Wide application range, excellent adaptability to materials, suitable for pharmaceutical, chemical, light industry, food, papermaking, mining, and other industrial sectors. It can handle suspensions with a solid concentration of up to 10% or less (or a volume concentration of 50% or less after 24 hours of free settling). It is ideal for solid particle equivalent diameters between 0.005 to 2 mm and a liquid-solid density difference of 0.05 g/cm³. It can effectively separate substances like calcium carbonate, polyvinyl chloride, lees, soybean dregs, paper pulp, vegetable oil, kaolin, sludge, and more.
2. Capable of continuous production, large capacity, low energy consumption per unit, and high degree of automation, especially suitable for industrial production lines.
3. Uses frequency conversion control and stepless speed regulation for optimal separation performance.
4. Operates in a fully enclosed environment, preventing pollution and odor, ideal for pipeline production.
5. Compact structure, small footprint, easy installation and maintenance, with wear-resistant tungsten carbide coating on vulnerable parts like the spiral outer edge, significantly increasing service life.
6. Contact parts are made of corrosion-resistant stainless steel and polished to mirror finish.
Product Structure: The horizontal screw discharge sedimentation centrifuge consists of a column-cone drum, screw discharge device, differential speed system, bearing seat, housing, main and auxiliary motor, and electrical system. The main motor drives the drum, while the auxiliary motor drives the planetary gear differential, creating a speed difference between the drum and the spiral. This allows the centrifuge to rotate at high speed under the action of centrifugal force for 24-hour continuous operation.
Working Principle: The drum and the spiral rotate at a high speed with a certain differential speed. The material enters the feeding chamber continuously through the feed tube and is accelerated into the drum under the influence of the centrifugal field. Heavy solids settle on the drum wall as a sediment layer. The spiral pusher continuously pushes the solid content towards the cone end, where it is discharged through the dry zone. The lighter liquid forms an inner liquid ring and exits through the overflow mouth at the large end of the drum.

The horizontal screw sedimentation centrifuge is used to separate suspensions via the principle of centrifugal sedimentation. It is suitable for suspensions with solid particle equivalent diameters of 3 cm or more, a liquid-solid density difference of 0.05 g/cm³, and a volume concentration of 0.5 to 40%. The motor drives the drum and the screw to rotate at a high speed with a certain speed difference. The material enters the screw feeding chamber continuously from the feeding tube and accelerates into the drum under the action of the centrifugal force field. Heavy solids form a sediment layer on the drum wall. The spiral pusher continuously pushes the solid content to the cone end, discharges it through the dry zone, and the lighter liquid forms an inner liquid ring that overflows from the large end of the drum.

3. Equipment Structure
It mainly consists of the drum and screw assembly, dynamic and differential components, pedestal (including damping system), shell parts, and electric automatic control system.
3.1. Power and Differential Group: Composed of motor, belt, planetary differential, spline, bearings, etc. Provides power for the motor, belt, and spline transmission, while the differential ensures smooth screw pushing and adapts to different materials.
3.2. Drum and Screw Group: Mainly composed of a cylindrical-conical drum, screw feeder, adjustable liquid column device, etc. The drum is driven by the motor to rotate at high speed, generating a strong centrifugal field for material separation. The main function of the screw pusher is to automatically discharge the solid slag separated by the rotating drum.
3.3. Frame and Shell Group: Includes the main motor, bearings, drum protection shell, drainage pipe, and discharge port components. Bearings provide a safe working platform, while the drum protection shell isolates the outside world when the drum rotates at high speed, preventing dangerous airflow. Drainage pipes and discharge ports guide the two phases after separation.
3.4. Control System: A dual-motor dual-frequency control system is used, ideal for complex solid-phase dewatering processes. It displays various process parameters, has alarm and protection functions for abnormal equipment status, ensuring a safer and more reliable system.

Fuyi 2018 Tricanter 3-Phase Decanter Centrifuge for Palm Oil Processing. Because the water content is 40-50%, soybean sauce and sludge have high liquid content. However, the decanter centrifuge separates the solid, and then the disc centrifuge can further separate it. Also,
With global water shortages intensifying and stricter environmental protection policies, the demand for sewage treatment continues to rise. We can foresee that more sewage and sludge will need treatment in the future. Municipal departments and industrial enterprises must choose harmless solutions to treat sewage and sludge. We should ensure that sludge treatment solutions are long-term and secure, and consider using high-tech equipment to recover valuable substances.
No matter what solution is chosen, the most economical and effective method is key to sludge treatment. The choice of technical equipment and corresponding processing for sludge dewatering determines the economy of the dehydration system.
Considering the costs of storage, transportation, incineration, or landfill, increasing the solid content of dehydrated sludge is crucial to reducing the cost of the sludge treatment system. To ensure the sludge treatment system meets the best processing requirements, it is necessary to optimize the sludge dehydration process to achieve higher dryness and smaller volume sludge.
The decanter centrifuge provided by Guangzhou Fuyi Company can achieve high separation acceleration (separation efficiency) and optimal differential and torque adjustment for the best dehydration effect. After efficient dewatering, the sludge volume is minimized, greatly reducing the cost of related sludge treatment processes.
