GN Company has been focus on manufacturing Decanter Centrifuge and Disc Separator for 13 years since 2009, including 2 phase separation & 3 phase separation.

Regarding to the physical parameters, separation requirement, and centrifuge selection for Classification, GN Company Engineers have suggestion as follow.

It’s fact that the ultrafine particle has great widely application, such as the ultrafine clay can be used as coating on high-grade forest paper, and plastic casing filter for submarine cable, high temperature resistant materials for rocket nozzles, and petrochemical catalytic carriers, etc.But it’s difficult to separate out the Ultrafine Particles (d≤2um) by common sieving, and it shall be separated by Wet Centrifugation, that is to make solid phase particles into solution (adding some amount of dispersant), then feeding into centrifuge. With certain separation factor, solid particles larger than a certain particle size dKp would settle down, while particles smaller than dKp would not settle down, so two groups of particles larger than dKp and smaller than dKp are separated in the solution.

(1) Physical Specifications: Solids content in the suspension before classification, and the distribution of the solid phase particles, the difference between the weight of solid phase and liquid phase, the viscosity, PH, etc.

(2) Classification requirements: the division ratio dKp of the particles to be classified, and the classification efficiency (ie, the yield of dKp particles).

(3) The most common selected model is Decanter Centrifuge.

Based on specific gravity difference of solid-liquid, particle size and dKp, GN Technical Engineers would suggest the exact model, with appropriate separation factor and slip. And during separation by decanter, the particle with size greater than dKp would settle down and be discharged from the small end as solids phase, while particles smaller than dKp remain in the liquid phase, and would be discharged with the liquid phase from the large end overflow port, thereby achieving particle classification.

For the classification of particles with small processing capacity, GN Company suggest three-foot centrifuge.

Welcome to contact GN Company, and we would send the exact the best solution for your project.

Decanter Centrifuge can be widely used for concentration, clarification, dehydration, the integrated concentration & dehydration, particle size classification and so on. It's widely used in the field of ETP, STP,WWTP, Chemical, Paper, Textile, Sugar, Mineral and Metallurgical Industries, Fertilizer Industries, Food Industries, Sewage and Effluent Treatment Plant, Refinery & Petrochemical Industry, etc.

GN Company has been focusing on manufacturing Decanter Centrifuge & Disc Separator for 13 years since 2007, with 3 factories in China Mainland, which are very close to the Beijing International Airport. GN Company can manufacture centrifuge for different applications with capacity ranging from 1m3/hour-120m3/hour, with different explosion proof standard, including ATEX, CNEX, IEC.

As there are different models of Decanter, GN Technical Engineers always do their best effort to find out the most match able model for the clients' specified project. Therefore it's always necessary for the clients to supply detailed & specified project details.

GN Company's Technical Engineers offer a Complete & Professional question list for the clients to answer, welcome to contact us for the list. While many potential clients have problems to answer the Question List, hereby we calculate the key questions as follow,

1. Solids Liquid separation? Or Solids Oil Water separation?

2. If the slurry can be separated by Gravity themselves?

3. Volume Percentage of Solid

4. Target for solid and liquid after treatment by our Machine

5. Explosion proof

6. Solids size

Welcome to contact us GN Sales Managers, and we would offer the Best & Economy solution for your project.

GN Separation and Conveying Company has become a professional manufacturer of Centrifuge for 13 years, and now the Company has 3 factories, and is capable to manufacture Decanter Centrifuge with bowl diameter from 9~30inch, that is about 220~760mm, with treatment capacity ranging from 1~2m3/hour-120m3/hour.

GN Company already supplied Decanter Centrifuge to UK, Netherlands, and now GN Company received more attention from other clients about our Decanter Centrifuge within Europe.

The first main application for Decanter Centrifuge is for Dehydration, and it is about to separate the solid phase from the liquid phase in the suspension, and the less liquid phase in solid phase, the separation is better.

Regarding to the selection of Centrifuge model for clients' project, GN Company's Technical Department has suggestions as follow,

If solid phase concentration is high, the particles are rigid bodies or crystals, and the particle size is big, so we suggest Centrifugal Filter. If the particles are allowed to be broken, so we suggest Scraper Centrifuge. If the particles are not allowed to be broken, so we suggest Cold Pusher or Centrifugal force Unloading Centrifuge.

The dehydration performance is not only related with the material itself, but also related with the centrifuge's centrifugal force, separation time, pore size of thescreen, porosity and other parameters, as well as the material of the centrifuge, Ph, the particle characteristics and process requirements, etc.

If solid phase concentration is low, and the particle size is very fine, or it is amorphous mycelium, we suggest Three-Food Sedimentation Centrifuge or Decanter Centrifuge without filter. And the centrifugal factor, Length/Diameter ratio, flow rate, overflow radius are all selected based on particle size of solid and the difference of the specific gravity of Liquid and Solids. And if the particle size is very uneven, the coarse particles can be removed by sieving, and then dewatered by centrifuge.

If the specific gravity of solid phase and liquid phase is close, and particle size is bigger than 0.05mm, so we suggest Centrifugal Filter. And if the particle size is too fine, the filter will run seriously. And if the filter is too thin, so the dehydration performance will decrease, and the amorphous mycelia and solid particles containing oil would block the filter.

And if requirement treatment capacity is high, we suggest continuous processing machine.
