Horizontal Decanter Centrifuge | Two/Three Phase Separation Waste Oil Centrifuge | zonelink
Horizontal Decanter Centrifuge for continuous solid-liquid separation features a high-speed drum, screw conveyor, and differential. The screw rotates slightly faster/slower than the drum, pushing solids to the small-end slag port while clear liquid overflows from the large end. This enables 24/7 industrial operation.
Key Components:
· Drum: Generates 2000-4000G centrifugal force
· Screw Conveyor: Pushes dewatered solids (0.005-2mm)
· Differential: Maintains precise speed gap (1-50 RPM)
Drive Options: Single motor (fixed speed), dual motor (variable speed), or hydro drive (automatic).
Applications: Wastewater, starch, fish meal, soybean protein dehydration.
Product Introduction
Horizontal Decanter Centrifuge Working Principle
The horizontal sedimentation screw discharge centrifuge (decanter centrifuge) consists of three core components:
1. High-speed drum (generates 2000-4000G centrifugal force)
2. Screw conveyor (same direction as drum, ±1-50 RPM differential)
3. Planetary differential (precise speed gap control)
Separation Process
Suspension enters drum → Solids settle on drum wall →
Screw pushes solids to small-end discharge →
Clear liquid overflows large-end ports
Result: Continuous two/three-phase separation of solids (0.005-2mm) from liquids.
Horizontal sedimentation screw discharge centrifuge is mainly composed of high speed drum, the same as the drum steering and the speed is slightly higher or lower than the drum differential and other components. When the suspension to be separated enters the centrifuge drum, the high-speed rotating drum generates a strong centrifugal force to precipitate the solid particles, which are denser than the liquid phase, to the inner wall of the drum. Due to the different rotating speeds of the spiral and the drum, there is a relative motion (i.e. the speed difference) between them. The solid phase deposited on the inner wall of the drum is pushed to the outlet of the small end of the drum by the relative motion of the spiral and the drum. The separated liquid is discharged from the other end of the centrifuge. The function of the differential (gear box) is to make a certain speed difference between the drum and the screw.
One motor drive, this is a very simple design and are therefore cheap to purchase and operate. One motor drive are used when the solids volume is constant, the solids are easy to convey and the requirements regarding the residual water content of the solids are not very stringent, in other words, bowl and differential speed regulating facilities are not necessary. The input shaft of the drive is set in motion by the main motor via a second belt drive. This generates the
differential speed as a function of bowl speed and gear transmission. This can be easily changed by replacing the belt pulleys.
Two motor drive, it enable the differential speed to be regulated cost-effectively under good operating conditions; wide regulating ranges are possible. The secondary motor sets the input shaft of the gear in motion and generates the differential speed as a function of bowl speed and gear transmission. The differential speed can easily be regulated by changing the motor speed. Two motor drive are used whenever solid volumes fluctuate significantly, when solids are conveyed under difficult conditions and when particularly stringent requirements are applicable with regard to residual water content.
Hydro drive, it works in a way which is similar to that of the two motor drive. The difference is to be seen in the design.Instead of the mechanical gear, a rotating hydromotor is installed; this is supplied with
hydraulic regulation by a pump unit. Because the differential speed is proportionate to the conveyed quantity of oil, automatic regulation can be provided without any problem.
Centrifugal sedimentation is the mixture of solid and liquid added to the cylindrical (or conical) rotor, due to the role of centrifugal force, solid in the liquid settlement, the settlement of the material is further squeezed by centrifugal force, extrusion of water, in order to achieve the purpose of solid and liquid separation. Centrifugal sedimentation is different from that under gravity. In gravity sedimentation, the acceleration of material sedimentation is equal to the acceleration of gravity, which is a constant value. In centrifugal sedimentation, the centrifugal force depends on the radius of rotation of the particles. Therefore, when the angular velocity is equal, the centrifugal force on the moving particles at different radius of rotation is not the same.
Horizontal settling screw discharge centrifuge main features
(1) Horizontal sedimentation screw discharge centrifuge has a wide range of applications, and can be widely used in chemical industry, petroleum, food, pharmaceutical, environmental protection and other needs. The field of liquid separation. It can complete the separation process of solid phase dehydration, liquid phase clarification, liquid - liquid - solid, liquid - solid - solid phase separation, particle size classification.
(2) The horizontal sedimentation screw discharge centrifuge has great adaptability to the material, and can separate a wide range of solid particle size (0.0005~2mm). When the particle size of the solid phase is uneven, it can be separated as usual.
(3 Horizontal sedimentation screw discharge centrifuge can be automatic, continuous, long-term operation, easy maintenance, can be closed operation.
(4) Horizontal sedimentation screw discharge centrifuge single production capacity, compact structure, small area, low operating costs.
