There are several types of decanter centrifuge currently utilized in the industry, the most common of which are vertical, horizontal and conveyor centrifuges. The principle behind a decanter centrifuge is based on the theory of gravitational 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 down at the base of the glass. With the mud congealed at the bottom, the water will be forced upwards, creating a clear separation between the two. A decanter centrifuge employs the same principles of gravitational force. However, unlike the glass mixture, the process is expedited through the use of continuous rotation. In fact, rotation provides anywhere from 1000 to 4000 times the normal gravitational force, reducing the time required for separation from hours to seconds. The concept of rotational separation is similar to rides found at amusement parks and county fairgrounds. In these rides, placing yourself at an angle allows you to overcome the gravitational forces induced by rotation. Similarly, a decanter centrifuge is essentially a bowl tube that rotates at an extremely high speed. The bowl tube is equipped with an internal conveyor which moves in the same direction but at a different velocity. Decanter centrifuge working principle Step 1: The slurry is inserted into the centrifuge through a connecting pipe and onto a conveyor. Step 2: Utilizing an internal feed compartment, the conveyor ushers the slurry through a nozzle into the bowl area. Step 3: The bowl rotates at high speeds to induce gravitational forces. Step 4: High speed rotation separates the solid material from the liquid in a matter of seconds. Step 5: The conveyor delivers the solid material upwards where it is discharged through a nozzle. Step 6: The solid material removed, the purified liquid is released from a separate output. The ability to purify a liquid makes decanter centrifuges ideal for waste water treatment facilities. However, there are variety of industries for which such centrifuges play an important role. Similar to other decanter equipment, centrifuges are simple to install and do not require a foundation to build upon. Their efficiency saves time and materials and is an essential component for many blue collar industries. http://www.kosunservices.com/solids_control_equipment/drilling_fluid_mud_leaner.html
