Technical principle
Disc centrifuge is a continuous, automated, high-speed rotating separation equipment. The core of its structure lies in a set of precision discs installed inside. These discs are stacked vertically inside the drum to form multiple extremely fine sedimentation channels, which significantly shorten the separation path and greatly improve the efficiency of solid-liquid or liquid-liquid separation.
Main components:
Drum: high-speed rotating main body, generating strong centrifugal force;
Disc group: enhance separation area and sedimentation path, improve efficiency;
Feeding system: realize constant flow, continuous feeding, reduce fluctuations;
Slag discharge system: optional manual or automatic slag discharge;
Control system: intelligent monitoring of operating parameters such as speed, pressure, temperature, and slag discharge frequency.
Working process:
The mixture is continuously fed into the center of the drum through the feed port;
The centrifugal force quickly settles the high-density solids or heavy liquids to the edge of the disc;
The light liquid moves toward the center and is discharged from the top outlet;
The separated solids are discharged through the automatic slag discharge system within a certain period of time;
The entire process is fully enclosed, continuous, high-speed and precise, and is suitable for industries with extremely high purity requirements.
Five core advantages of disc centrifuges
1. High separation efficiency, suitable for fine process
Thanks to the existence of the disc structure, the disc centrifuge has a shorter separation interface, a smaller sedimentation path, and a stronger centrifugal acceleration. It can complete high-precision separation within a few seconds, and is particularly suitable for processing suspensions or emulsions with particle sizes less than 5μm.
2. Continuous feeding and discharging, high process efficiency
Compared with traditional intermittent equipment, disc centrifuges support fully automatic, continuous feeding and discharging, eliminating frequent shutdowns, greatly improving production rhythm and efficiency, and are ideal supporting equipment for modern production lines.
3. Small footprint and compact structure
The equipment is highly integrated, with an area of only half that of traditional equipment. It is especially suitable for high-end production bases with limited plant space, and is easy to layout and dock with production lines.
4. Multiphase separation, adaptable to complex materials
Not only can it perform solid-liquid separation, but it can also achieve liquid-liquid-solid three-phase separation. It is widely used in multiphase material processing such as dairy separation (fat/skim milk/sediment) and plant extraction (oil/water/slag).
