Stainless Steel Horizontal LW Series Alumina Decanter Centrifuge Drilling Mud Solids

How Does Screw Decanter Centrifuge Work?

With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase.

The heavy liquid (water) collects in the middle between the oil and the solids layer. Thus the two liquids separated from each other can be drawn off from the decanter. The solids are transported via the scroll to the discharge openings as it happens also in 2-phase separation.

Typical applications of 3-phase separation are the production of edible oils such as olive oil, oil sludge processing, the production of biodiesel .

Screw Decanter Centrifuge Feature

• 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.[4] Its versatility allows the machine to have various functions such as operating for thickening or dewatering
