Mechanical separation technology of decanter centrifuge

The rapid development of the decanter centrifuge over the 20th century saw it expand into a vast range of over 100 industrial applications. Further development since then has seen the refinement of machine design and control methods, improving its overall performance, which allows the system to respond quickly to varying feed conditions.
The newest development in decanter centrifuge technology aims to achieve enhanced control of the separation process occurring inside the decanter. The way in which manufacturers aim to address this is by utilising variable mechanical devices in the rotating part of the decanter centrifuge.
To control the separation process, the operational parameters should be transferred from the rotating part to the stationary part of the decanter whilst also constantly controlling and maintaining the mechanical device inside the process region. This can be achieved using hydraulic and electronic transfer systems. A hydraulic drive motor is easily able to access the rotating area of the decanter centrifuge.
There are numerous manufacturers specialising in mechanical separation technology that have adapted these new designs into industrial standard equipment. This advanced technology has allowed decanter centrifuges to operate up to 250 cubic metres per hour and has developed numerous designs such as the Z8E decanter, known as the world's largest decanter centrifuge with an adjustable impeller, which supplies a torque of 24,000 newton metres. Other designs can reduce power consumption by up to thirty percent due to a large slurry discharge, and are best utilised in the water treatment industry.

Decanter centrifuge is the last stage equipment in drilling mud system for solids control and mud cleaning. The superiority of decanting centrifuge is embodied in the solids processing size. Decanter centrifuge could remove the solid particles with size 2-7 microns using the principle of centrifugal action, it is an ideal choice for separating particles in drilling mud. Always there is a screw pump or submersible pump to feed the mud to decanter centrifuge.
