分类： 3 Phase Decanter Centrifuge

Decanter Centrifuge Manufacturer in China

Compared with other separation machines, centrifuges can not only obtain solid phase with low moisture content and high-purity liquid phase, but also have the advantages of small size, good sealing, continuous operation, automatic remote control, etc., so they are widely used in chemical industry, Petrochemical, petroleum refining, light industry, medicine, food, textile, metallurgy, coal, mineral processing, shipbuilding, environmental protection, military and other departments, such as the recovery of pulverized coal for wet coal mining; the purification and reuse of drilling mud for oil mining; uranium Concentration of isotopes; sludge concentration and dehydration of sewage treatment; refining of petrochemical products; extraction of antibiotics and pesticides; manufacture of milk, yeast, beer, fruit juice, sugar, orange oil, animal and vegetable oil, rice bran oil, starch and other foods; The dehydration of fabric fibers; the purification of lubricating oil and fuel oil need to use centrifuges. It can be seen that the centrifuge has become widely used separation equipment in various sectors of the national economy.

The application functions of the centrifuge mainly include: dehydration, clarification, concentration, classification, separation and so on. Different centrifuge models must be selected according to different material characteristics and separation requirements, which leads to the problem of centrifuge selection. In the actual production process, due to the selection of suitable separation equipment for some projects, the process is simple, the energy consumption is reduced, the product quality is improved, and good economic benefits are obtained; but there is also improper selection of centrifuges, which makes the production process unable to proceed normally. , resulting in greater economic losses. Therefore, in the engineering design and technical transformation, the problem of how to correctly select the centrifuge has been recognized and valued by the majority of engineering and technical personnel.

GN Company Supplied Decanter Centrifuge for African Client

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

The decanter centrifuge is a spiral unloading sedimentation centrifuge. It is mainly composed of a high-speed rotating drum, a screw conveyor with a hollow shaft and a differential with the same rotation as the rotating drum and a slightly lower speed than the rotating drum. When the suspension to be separated is sent into the drum by the hollow shaft, it is immediately thrown into the drum cavity under the action of the centrifugal force generated by the high-speed rotation.

The high-speed rotating drum generates strong centrifugal force to sling the solid particles with higher density than the liquid phase on the inner wall of the drum to form a solid layer (because of the ring shape, called the solid ring layer); due to the low density of water, the centrifugal force is small Therefore, the liquid layer can only be formed inside the solid ring layer, which is called the liquid ring layer.

Due to the different rotation speeds of the screw and the drum, there is a relative movement (that is, the difference in rotation speed) between the two. The relative movement of the screw and the drum is used to slowly push the sludge in the solid ring layer to the cone end of the drum and pass through the drying zone. After that, it is continuously discharged from the outlets distributed around the circumference of the drum; the liquid in the liquid ring layer is continuously discharged from the weir to the outside of the drum by gravity to form a separated liquid.

GN Company Supplied Decanter Centrifuge for European Client

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 Supplied Decanter Centrifuge for European Client

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.
