Decanter Centrifuges feature full-automatic continuous feeding and discharge . This chemical separation equipment has been applied two-phase(solid-liquid) and three-phase(solid-liquid-liquid) slurries separation industry of chemicals, pharmaceutical, environment protection, as well as mining and food, etc.
For different types of raw materials. We will make corresponding adjustments and settings. To ensure that different raw materials can achieve the best separation effect.
Our decanter centrifuge can operate 24/7 with full automation. Provide efficient and powerful assurance for your separation operations.
How does it work
The feed product is pumped into the decanter centrifuge through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl has is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g. Under these forces, the solid particles with higher density are collected and compacted on the wall of the bowl. A scroll (also screw or screw conveyor) rotates inside the bowl at a slightly different speed. This speed difference is called the differential speed. This way the scroll is transporting the settled particles along the cylindrical part of the bowl and up to the end conical part of the bowl. At the smallest end of the conical part of the bowl, the dewatered solids leave the bowl via discharge opening. The clarified liquid leaves through a paring disc (internal centripetal pump).
Advantages:
- Decanter centrifuges have a clean appearance and have little to no odour problems.
- Not only is the device easy to install and fast at starting up and shutting down but also only requires a small area for operation compared to other competitive processes.
- The decanter centrifuge is versatile as different lengths of the cylindrical bowl section and the cone angle can be selected for different applications. Also, the system can be pre-programmed with various design curves to predict the sludge type, while some competitive processes, such as a belt filter press, cannot change the belt type to operate for different sludge types. Its versatility allows the machine to have various functions such as operating for thickening or dewatering.
- The machine can operate with a higher throughput capacity than smaller machines. This also reduces the number of units required.
- The device is simple to optimise and operate as it has few major variables and reliable feedback information.
- The decanter centrifuge has reduced labour costs compared to other processes, as it requires low continuous maintenance and operator attention.
- Compared to some competitive process such as the belt filter process, the decanter centrifuge has more process flexibility and higher levels of performance.
Limitations:
- The decanter centrifuge cannot separate biological solids with very small density differences, such as cells and viruses. A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge.
- The machine can be very noisy and can cause vibration.
- The device has a high-energy consumption due to high G-forces.
- The decanter centrifuge has high equipment capital costs. Hard surfacing and abrasion protection materials are required for the scroll to reduce wear and therefore reduce the maintenance of the scroll wear.
