GN Decanter Centrifuge for Industry Application

Centrifuges can be installed in a relatively small footprint; have a high washing capabiiity; produce low cake moisture; achieve a high capacity throughput and can provide the user with a totally enclosed and contained vapour-tight processing facility.
Centrifugal filtration is also considered to be one of the most effective methods of removing impurities.
Correct selection of a centrifuge is based on two key concerns: economic expectations ald technical requirements.
Once the process is clearly defined, it is easier to identify variables such as the percentage of suspended solids, volumetric slurry throughput, solids throughput and the required product consistency at discharge. Materials usually exit the centrifuge in a powdered or granular form, but there are some instances in which it can also be discharged as a paste. Product consistency will to some extent dictate the method of materials handling and trarrsportation.
The prospective user should also clearly define exactly what the centrifugal process is required to achieve. Does the material require clarification, classifi cation, degritting, thickening, dewateri.rg, washing or separating and repulping, and is the process a solidliquid, liquid-liquid or a three phase liquid-liquid-so1id duty?
Other considerations include the expected’G’ force; allowable cake dryness; allowable solids in the discharge liquors; product temperature; viscosity; specific gravity; pH and whether the process should be batch or continuous.
GN design and manufacture both decanter centrifuge and three-phase centrifuge for industry separation. Solid bowl decanter centrifuges have been operating according to the same basic principle since the 19th Century.
GN design specific centrifuges according to specific separation tasks and the use of resilient, high-quality materials have improved the performance of the centrifuges.
Moreover, GN owns a branch for design PLC and electrical control system; this gives GN advantages in electrical components for measuring and control technology. The performance and availability of the decanter centrifuge or three-phase centrifuges are significantly improved by the control system..
Main Application of GN Industry Centrifuges
Dewatering sludges / mud and suspensions
Thickening sludges or mud
Clarifying different type liquids
Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase
Classifying solids in a wet suspension by grain size
Separation of solids according to various densities
