Small Decanter Centrifuge for Pilot Scale and Industrial Applications
A Small Decanter Centrifuge is an ideal solution for pilot plants, research facilities, and small-scale industrial processes where efficient solid-liquid separation is required but a full-size industrial decanter centrifuge is unnecessary.
Compared with conventional large-capacity decanter centrifuges, small decanter centrifuges provide a compact footprint, lower operating cost, flexible installation, and excellent separation performance for low to medium throughput applications.
SEPARATECH Small Decanter Centrifuge is designed for process development, pilot testing, and specialized industrial applications, offering reliable separation technology based on the same engineering principles used in full-scale industrial decanter centrifuge systems.

Compact Design of Small Decanter Centrifuge

A Compact Decanter Centrifuge provides the advantages of continuous centrifugal separation in a smaller and more flexible configuration.
Traditional industrial decanter centrifuges are normally designed for large processing capacities in industries such as wastewater treatment, food processing, chemical manufacturing, and mining. However, many applications require a smaller solution for:
- Process testing
- New product development
- Pilot production
- Small batch manufacturing
- Laboratory-to-industrial scale-up
A small decanter centrifuge offers:
- Reduced installation space
- Lower power consumption
- Easier transportation and installation
- Flexible process adjustment
- Lower investment cost
This makes it particularly suitable for companies developing new separation processes or operating specialized production lines.
Small Decanter Centrifuge Working Principle
The working principle of a Small Decanter Centrifuge is based on continuous sedimentation under high centrifugal force.
During operation, the feed slurry enters the rotating bowl through the feed pipe. Under thousands of times gravitational acceleration (G-force), solid particles rapidly settle against the bowl wall. Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor.
The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedimentation of the solids on the wall of the bowl.
The conveyor rotates in the same direction as the bowl, but slightly slower, thus moving the solids towards the conical end of the bowl. The cake leaves the bowl through the solids discharge openings into the casing. Separation takes place throughout the entire length of the cylindrical part of the bowl, and the clarified liquid leaves the bowl by flowing over adjustable plate dams into the casing.
The continuous operation principle allows the small decanter centrifuge to achieve efficient solid-liquid separation without manual filtration or batch operation.

Small Decanter Centrifuge vs Industrial Decanter Centrifuge
Although a Small Decanter Centrifuge follows the same separation principle as a large industrial decanter centrifuge, there are important differences in application requirements.
| Feature | Small Decanter Centrifuge | Industrial Decanter Centrifuge |
|---|---|---|
| Processing capacity | Low to medium flow rate | High continuous capacity |
| Application | Pilot plants, R&D, specialty production | Large-scale production |
| Installation | Compact footprint | Requires larger installation space |
| Investment | Lower initial cost | Higher capital investment |
| Flexibility | High flexibility for testing | Optimized for stable production |
For companies developing new processes, a small decanter centrifuge provides an effective bridge between laboratory testing and full-scale industrial production.
