Decanter centrifuge is one of the main products in GN production line. It is usually used for solid-liquid separation, and some three-phase decanter centrifuges will also be used for liquid-liquid-solid separation. The process of solid-liquid separation or liquid-liquid-solid separation is often encountered in the process of modern industrial production. Therefore, decanter centrifuge plays an important role in modern industrial production.

A typical application of decanter centrifuge is used as sludge dewatering equipment in the process of municipal sewage treatment. The sludge at the bottom of the sedimentation tank in the sewage treatment plant needs to be cleaned regularly to ensure the space of the sedimentation tank to continuously receive sewage. In order to speed up the cleaning and transportation of sludge, the sludge at the bottom of the tank needs to be dewatered. Adding flocculants to the sludge can better make the fine particles in the sludge gather into flocs. After the flocculated sludge enters the centrifuge, the separated clean water will be relatively clear. GN T series dewatering decanter centrifuge is a centrifuge product specially designed by GN for environmental protection water treatment industry, which can be adapted to sludge with high solid content. The screw blade and slag discharge port are protected by tungsten carbide plate or alloy sleeve, which can prolong the service life of the equipment.

Another typical application of decanter centrifuge is to separate fine drilling cuttings from drilling mud in the mud system. The drilling mud treated by centrifuge can be reinjected into the mud system for recycling. The decanter centrifuge in widely used in mud systems of oil and gas drilling, horizontal directional drilling, TBM, and even some construction mud treatment projects.

In order to meet different working conditions or different feeding conditions on site, according to customer requirements, GN can equip the decanter with VFD control cabinet to achieve different treatment objectives by adjusting the speed. At the same time, the control cabinet is also equipped with the relevant control of the screw feeding pump, which can realize the start and stop interlock function of the feed pump and the centrifuge, and improve the safety of field work and the reliability of equipment operation.

GN Solids Control shipped two sets of ATEX explosion proof standard decanter centrifuges to a Middle East oil service company last week after these days hard work. GN Solids Control has sold and manufactured more than 50 sets decanter centrifuges since the beginning of this year.

GN Solids Control is able to manufacture Europe ATEX, IEC Ex, and CNEX standard explosion proof standard motors and electrical control boxes for global drilling companies and oil service companies. As for these 2 sets centrifuges, they are both ATEX Zone 1 standard with VFD, explosion proof air conditioners guarantee the centrifuge working in the hot temperature up to +55 C degree.
These two ATEX VFD centrifuges are both 14 inch bowl size. To meet the harsh working environment, GN Solids Control use duplex stainless steel to build the rotating bow, and along the screw propeller it is fixed with tungsten carbide tiles to protect the propeller running a long time with a very small weariness.
GN VFD control box is fixed with a smart HMI, all centrifuge working parameters can be changed or working conditions can be monitored on it.The two main centrifuge bearings are fixed with temperature sensors and centrifuge frame fixed with vibration sensor, signal lines connected with the PLC which is also able to remind workers in case there are any abnormal alarms.

GN decanter centrifuges are widely used in the drilling mud solids control. And some big bowl like 18 inch and 22 inch centrifuges are also very popular in the barite recovery or drilling mud control or drill cuttings waste management.
GN Solids Control is able to provide modular decanter centrifuge unit includes supporting stand, feeding screw pump and liquid catch tank. Some other equipment like drying shaker, cuttings dryer, 3 phase disc centrifuge etc be also used with GN 2 phase decanter centrifuge.

Recently, GN shipped out one set 3-hase decanter centrifuge including VFD control cabinet to Middle East client coming from environmental company. 3 Phase decanter centrifuge is one of GN main products, different from the 2-phase decanter centrifuge, it is used for separation of mixture of solids and two types of immiscible liquids and solids.

The 3 phase decanter centrifuge shipped is the model GNSX520 with bowl diameter 520mm. It adopts the electrical dual-motor driving system. The main motor is driving the bowl and the back motor is driving the screw via pulley device. This model is equipped with a VFD control cabinet. Inside the control cabinet, there are 3 VFDs for main motor, back motor and the feeding pump. Operator can set up the running parameters in the HMI touch screen to adjust the running condition, like bowl speed, scroll speed to obtain the expected performance. GN 3-phase decanter centrifuge is equipped with lube oil circulating system for the main bearing lubrication. This real time lubrication system ensures the stable running of the machine.

In order to extend the service life of the 3-phase decanter centrifuge, GN adopts tungsten material protection at the screw blades, and installs wear-resistance bushing at the slag discharge port. There are 2 ports at the bottom of the collection box, the slag and the light liquid phase will be discharged respectively from these two ports, while the heavy liquid phase is discharged out by using the centripetal pump. Operator can adjust the lever to obtain a suitable interface of oil and water to get the more clear oil or water.

GN 3-phase decanter centrifuge has a widely application like plant edible oil production, kitchen waste treatment, etc. One of the typical applications is used in GN oil sludge treatment system as a combination equipment to replace the 2-phase decanter centrifuge and disc stack separator. Which will meet the contractor’s requirements of high cost performance.

Recently GN shipped out one unit of 3 phase disc separator that would be used for seabuckthorn oil production. Seabuckthorn oil is natural oil extracted from seabuckthorn fruit. It is rich in unsaturated fatty acids, vitamins and trace elements. It has high medicinal value, which makes It can not only play a health care role in cardiovascular, cerebrovascular, liver and respiratory system, but also help to strengthen brain and intelligence.

In the production of seabuckthorn oil, the seabuckthorn fruit needs to be cleaned and ground to separate the oil from the fruit cells, and then extracted. After grinding, seabuckthorn fruit forms a mixture of fruit residue, water and oil. If you want to extract the oil from the mixture, you need three-phase separation, and the disc machine can achieve this purpose.

Disc separator is a high-speed centrifugal separation equipment. The materials fed into it are usually solid-liquid mixture or liquid mixture with different densities. The disc separator bowl rotates at high speed. Due to the density difference, the materials in the equipment will form stratification under the action of centrifugal force; the solid phase will sink and be discharged from the slag discharge port, while the liquid phase will be discharged from the outlet at the top of the equipment under the action of centripetal pump.

Disc separator used in the food industry or pharmaceutical industry need to have high requirements for some materials in contact with materials. Stainless steel materials are usually used, and the sealing materials should also have food grade safety certification. GN disc separator is equipped with a control cabinet with PLC and frequency converter. Users can monitor the operation of the equipment and set and adjust the operation parameters through the touch screen, so as to achieve the best separation effect.

As a professional separation solution provider, GN is committed to providing cost-effective separation equipment or complete systems. For more information about disc separator, please contact GN separation.
