dewatering centrifuge | GN Decanter Centrifuge

Overview about Centrifuge’s Applications and Selection

Compared with other separation equipment, Centrifuge can be used not only to get low moisture solid phase and high purity liquid phase, but also it has advantages of small footprint, good sealing, continuous operation, and automatic remote control, etc. So Centrifuge is widely used in chemical, petrochemical, petroleum refining, medicine, food, textile, metallurgy, coal, shipbuilding, environmental protection, military industry, and others. Such as purification and reuse of drilling mud for petroleum, sludge concentration and dehydration for sewage treatment, refining of petrochemical products, extraction of antibiotics and pesticides, production of milk, yeast, beer, fruit juice, sugar, orange oil, animal and vegetable oil, and fabric fiber dehydration, production of starch and other food, fabric fiber dehydration, purification of lubricants and fuel oil, etc. Centrifuge has become widely used separation equipment for different industries of the national economy.

There are different processing requirement in the production process, including Dehydration, Clarification, Concentration, Classification, and Separation. The essence of Dehydration and Clarification is to separate solids and liquid in the suspension, Dehydration is to remove liquid phase from solid phase, and Clarification is to remove solid phase from liquid. Concentration is to increase the content of solid phase in the solid-liquid mixture. Classification is the separation of particles of different size in the suspension. Separation generally refers to the separation of two mutually incompatible liquid phases.

GN Company Developed New Market for Decanter Centrifuge

GN Company Technical Engineers developed new Technology for Decanter Centrifuge, including dewatering, separation, and clarifying.

Dewatering Decanter Centrifuge is mainly used for dewatering of municipal and industrial wastewater sludge. It is designed for easy separation material, such as coarse particle size, high density difference of solid and liquid, low viscosity, high concentration. And its main application is for drilling mud, ETP, WWTP, oily sludge, cutting fluid, etc.

Separation Decanter Centrifuge has beach angle of 15 degree, it is designed both for clarity of liquid phase after separation, also for the dryness of solids phase. The decanter centrifuge is especially suitable for find soft material separation, which is difficult to separate. This decanter centrifuge is suitable for small particles, small density difference of solid and liquid, large viscosity and small concentration. And its main application is for soybean milk, plant starch recovery, fermentation liquid, baths, etc.

Clarifying Decanter Centrifuge, with beach angle of 20 degree, suits for small particle size, low density difference between solids and liquid, moderate viscosity, moderate concentration. And its main application material is for Edible Oil, Pectin, Plant Protein, Animal Protein, Starch, Juice, etc.

Decanter Centrifuge

Besides Decanter Centrifuge, GN Company also manufactures and supplies Chemical Dosing Unit and Progressive Cavity Pump. Simple mechanical separation can only be used to separate particles of 2~ 5 microns and Chemical Dosing Unit working together with high speed Decanter Centrifuge can separate the fine solids less than 2 microns.

GN Decanter Centrifuge for Middel East Market

Recently GN Company finished production of 10 sets of Decanter Centrifuges, ordered by a client from Middle East Company.

The model this client ordered is GNLW363, with bowl diameter about 360 mm, bowl speed 0~3200 RPM, and G force 3063 G, widely used for Mud/Sludge Dewatering, thickening, and different types of liquids clarifying.

GN Decanter Centrifuge working procedure is as below,

feeding the Liquid/Sludge into the decanter centrifuge, and both screw conveyor (within Bowl) and Bowl would rotate at a high speed, but different rate.

The solid and liquid would come into Two Rings separately, named Solid Ring and Liquid Ring.

While liquid’s specific gravity would be less than solid, so Liquid Ring would be closed to the Central Axis, and the Solid Ring would be closed to Bowl.

Because of the different speed of Bowl and Screw Conveyor, so Solid would be pushed to Cone end, while Liquid would be pushed to other end.

GN is a professional manufacturer Decanter Centrifuge for 11 years, and supplying about 250 sets for International market every year, including USA, Canada, Netherlands, UK, Australia, UAE, China, etc.

GN can supply from 9 inch (220mm) to 30 inch (760mm), with bowl length and diameter ration up to 4.2, and adjustable G force is up to 3000G, to meet different requirements.

GN guarantees the goods for 14 Months after shipment or 12 months after commissioning whichever comes first.
