Product Description
3 phase horizontal screw centrifugal dehydrator is a high-speed, stable and efficient automatic control equipment, which is mainly used for solid-liquid oil clarification and separation in food waste treatment, petrochemical and other industries. All parts and components in contact with materials are made of high-grade stainless steel materials, which effectively reduces the corrosion of the separated materials and the surfaces of the parts in contact. The separated materials enter the drum of the centrifuge. Under the strong centrifugal force field, the materials are accelerated by the accelerating cone and then enter the material separation zone between the screw pusher and the straight section drum. The solid materials with large specific gravity move along the direction of the drum wall, accumulate in the sediment zone of the drum wall, and are transported out of the centrifuge by the screw pusher. The liquid phase materials with small specific gravity are pushed on the surface of the sedimentation tank by the heavy phase materials, and move toward the light phase outlet under the axial force of the cone section drum. The separated light phase material is thrown out by the centrifugal force of the drum itself, and flows out of the centrifuge after free convergence.
The Ingenious Working Principle of Decanter Centrifuges
A decanter centrifuge thrives on the principle of buoyant separation. Within a mixture, a denser component naturally sinks, while a less dense one rises. In a decanter centrifuge, continuous spinning magnifies settling speed, generating extreme g-forces ranging from 1000 to 4000 G's. This innovation reduces settling times drastically, transforming hours-long processes into mere seconds, delivering fast and manageable separation results.
Imagine a decanter as a cylindrical sedimentation tank rotating around an axis. In this setup, denser solid particles gravitate to the bottom, forming a solid phase sediment. In a centrifuge, however, centrifugal acceleration takes the lead. Denser particles are propelled outward in the rotating bowl, forming a sediment along the inner wall. The rapid application of centrifugal forces, approximately 3000 g, ensures separation occurs exponentially faster than in a gravitational field.

Detailed Photos
What is Decanter centrifuge?
- A decanter centrifuge is a type of centrifuge that is used to separate solids from liquids in a mixture. It is a continuous process that uses centrifugal force to separate the two components.
- The mixture is fed into the centrifuge, and the solids are separated from the liquids by the centrifugal force generated by the spinning of the centrifuge.
- The separated solids and liquids are then discharged from the centrifuge through separate outlets.
- Decanter centrifuges are used in a wide range of industries, including chemical, pharmaceutical, food processing, and environmental engineering.
- They are particularly useful for separating solids that are too fine or too dense to be effectively separated by other methods, such as sedimentation or filtration.
- Decanter centrifuges are also used to dewater sludge and to separate emulsions.
- They are known for their high efficiency, low maintenance requirements, and ability to handle large volumes of material.
