decanter centrifuge

Recently client from Europe ordered one unit of Decanter Centrifuge for olive oil processing, with capacity about 10 m3 per hour.

GN Company has been a professional manufacturer of Decanter Centrifuge for about 10 years, with capabilities to manufacture Decanter Centrifuge with bowl diameter from 220mm to 760mm, and capacity from 1~2 m3 per hour to 120 m3 per hour.

When the clients come to GN for new projects, the Engineers always suggest the clients to answer a professional questionnaire, in order to find out the best model for clients’ project.

The questionnaire mainly includes questions as follow.
1. What is the main purpose of separation, and capacity requirement? For example, solids dewatering, solid-liquid separation, or solid-liquid-liquid separation. GN Engineers need to consider 2-phsae or 3-phase Decanter/Separator for clients’ projects.
2. What is the make-up of feeding inlet? What is the liquid phase and solids phase, and where are they from?
3. What is solid content percentage in the feeding inlet? It’s better to calculate the percentage by volume, instead of weight. Solids content plus capacity requirement can help engineers to find out the exact model. GN Company now is capable to manufacture 760mm bowl diameter decanter, with capacity 100~120 m3 per hour.
4. What is the solid particle in the feeding inlet? Engineers shall consider if it is necessary to add pre-treatment equipment, which can remove coarse particles. For example, 10mm particles.
5. What is the client requirement after treatment by Decanter Centrifuge? Some clients need the outlet cake to be as dry as possible, some clients need the outlet liquid to be clean, and some other clients choose between them.

There are some other details, which shall be put high attention on, for example, if the Decanter shall be explosion proof or not, if the feeding inlet has high corrosive (for example, high content of chloride), etc.

Welcome to contact GN Sales Managers, and they would offer one stop turnkey solution for your project.

GN Company has been a professional manufacturer of Decanter Centrifuge for about 10 years, with capabilities to manufacturer Decanter with bowl diameter from 220mm~760mm, and treatment capacity from 1 m3 per hour to 120 m3 per hour.

Besides 2-phase Decanter Centrifuge, GN Company is also capable to manufacture 3-phase Decanter Centrifuge, which is used for solid-liquid-liquid separation. 3-phase Decanter Centrifuge has two rotors, including drum and screw. When the drum and screw rotate at high speed, there would create centrifugal force, which is many times bigger than gravity. So the particles would be separated from the liquid, and settle on the inner wall of the drum. Because the screw rotates at slower speed than drum, therefore the solids would be pushed out from the slag outlet. The liquid would form two separate layers, because of the difference of density. The heavy phase layer would drawn against the wall of drum by the centripetal pump, and would be discharged from heavy-phase outlet. The light phase layer is close to the spiral end, and discharged by overflow. The whole process is continuous and highly automatic.

The material touch part of GN 3-phase Decanter Centrifuge is made of high grade duplex stainless steel, which is much better than SS 316 in strength and corrosion resistance. The Solids Discharge Port is protected by Tungsten Carbide Insert. The bearings are from international reputable brand, and clients can find spare parts easily from local market.

Welcome to contact GN Sales Managers, and they would offer one stop turnkey solution based on clients’ requirement.
