The Working Principle of the Decanter Centrifuge

In order to fully understand the working principle of a decanter centrifuge, we must first define the role of the centrifuge. In many industrial jobs, solid materials are often mixed with liquids, contaminating water supplies or turning slurries into sludge. Decanters are very useful because they separate solids and liquids and have become an important part of wastewater treatment facilities.

 

In order to fully understand the working principle of a tapered roller bearing we must first define the role of the centrifuge. In many industrial jobs, solid materials are often mixed with liquids, contaminating water supplies or turning slurries into sludge. Decanters are very useful because they separate solids and liquids and have become an important part of wastewater treatment facilities as well as the chemical, petroleum and food processing industries. In addition, without centrifuges, many of these companies would become so inefficient that they could not function.

 

The Working Principle of the Decanter Centrifuge

 

There are several types of decanter centrifuges used in industry today, the most common of which are vertical, horizontal and conveyor centrifuges. The principle behind decanter centrifuges is based on the theory of gravity separation. For example, if you fill a glass with a mixture of mud and water, over time the weight of the mud will cause it to settle at the bottom of the glass. As the mud condenses at the bottom, the water will be forced upward, creating a visible separation between the two.


The decanter centrifuge uses the same principle of gravity. However, unlike the glass mixture, the process is accelerated by the use of continuous rotation. In fact, the spinning provides 1000 to 4000 times the normal gravity, thus reducing the time required for separation from hours to seconds.
The concept of rotational separation is similar to the rides found in amusement parks and county fairs. In these rides, placing yourself at an angle allows you to overcome the gravity caused by rotation. Similarly, a decanter centrifuge is essentially a bowl tube that spins at a very high speed. The rotating tube is equipped with an internal conveyor that moves in the same direction but at a different speed.

 

The Working Principle of the Decanter Centrifuge

 

Step 1: The slurry is inserted into the centrifuge through the connecting tube and conveyed onto the conveyor belt.
Step 2: Using the internal feed chamber, the conveyor introduces the slurry through the nozzle into the bowl area.
Step 3: The bowl is rotated at high speed to create gravity.
Step 4: The high speed rotation separates the solid material from the liquid in a few seconds.
Step 5: The conveyor conveys the solid material up and out through the nozzle.
Step 6: The solid material is removed and the purified liquid is released from a separate output.

 

The ability to purify liquids makes decanter centrifuges ideal for wastewater treatment facilities. However, this type of centrifuge plays an important role in many industries. Similar to other decanter centrifuge equipment, centrifuges are simple to install and do not require a foundation. Their efficiency saves time and materials and is an important part of many blue-collar industries.
