GN decanter centrifuge

The working principle of the centrifuge is as follows: the rotating drum and the spiral rotate at a certain differential speed in the same direction, the material is continuously introduced into the inner cylinder of the feeding spiral by the feed pipe, and is accelerated into the rotating drum. Under the action of centrifugal force field, the heavier solid substance is deposited on the wall of the rotating drum to form a sediment layer. The feed screw pushes the deposited solid phase continuously to the end of the drum cone and drains out of the machine through the slag discharge port. The lighter liquid phase forms the inner liquid ring, which continuously spills out of the drum through the overflow port at the big end of the drum and drains out of the machine through the drain port. This function continuously feeds, separates, washes and discharges at full speed. It has the characteristics of compact structure, continuous operation, smooth running, strong adaptability, large production capacity and easy maintenance. Suitable for separating suspensions containing solids with particle size greater than 0.005mm and concentration range of 2-40%. Widely used in chemical, light industry, pharmaceutical, food, environmental protection and other industries.

GN Decanter Centrifuge Function

1)Dewatering sludge / mud and suspensions

2)Thickening sludge or mud

3)Clarifying different type liquids

4)Separating 3-phase mixtures, i.e. two immiscible fluid phases and a solid phase

5) Classifying solids in a wet suspension by grain size

6) Separation of solids according to various densities

GN solid-liquid separation decanter centrifuge

When you need separate solid /liquid mixtures with high solids content, you can choose a decanter centrifuge.Decanter centrifuges can be optimally adjusted for specific applications. Applications range from sludge dewatering to classification or wet classification to solid classification.

GN decanter is a horizontal,continuously working and continuously spiral discharging sedimentation centrifuge.It is used in a variety or industries for separating all kinds of solid liquid suspension,defecating liquid phase with graded grains,and dehydrating sludge.

Main Characteristics
1.Continuous working,spiral discharging,high capacity.

Special Allocation
Following allocation can be possible to meet customer’s demand
1.Frequency conversion plus PLC controlling system
2. Protection system for vibration and temperature rising
3.Feeding speed control
4.Gas-liquid separation device on liquid outle

GN decanter centrifuge

GN dewatering decanter centrifuge is T series decanter centrifuge with beach angle of 8.5 degrees. T series decanter centrifuge is generally used dewatering and thickening purpose.

GN decanter centrifuge is a kind of Separation Centrifuge, it help you with solid-liquid/ solid-liquid-liquid separation within one single continuous process.

It is a high-speed, stable and efficient automatic control equipment, which is mainly used for solid-liquid oil clarification and separation in food waste treatment, petrochemical and other industries. All parts and components in contact with materials are made of high-grade stainless steel materials, which effectively reduces the corrosion of the separated materials and the surfaces of the parts in contact. The separated materials enter the drum of the centrifuge. Under the strong centrifugal force field, the materials are accelerated by the accelerating cone and then enter the material separation zone between the screw pusher and the straight section drum. The solid materials with large specific gravity move along the direction of the drum wall, accumulate in the sediment zone of the drum wall, and are transported out of the centrifuge by the screw pusher. The liquid phase materials with small specific gravity are pushed on the surface of the sedimentation tank by the heavy phase materials, and move toward the light phase outlet under the axial force of the cone section drum. The separated light phase material is thrown out by the centrifugal force of the drum itself, and flows out of the centrifuge after free convergence.

GN solid-liquid separation decanter centrifuge

Solid-liquid separation decanter centrifuge is named decanter, when you need do solid/liquid mixtuers with high solid content, you can choose a decanter centrifuge.

sludge decanter centrifuge are used for sludge deawtering without chemical conditioning but when the sludge is conditined with polymieric electrolytes, the solid retention rate and the quality of the liquid after centrifugation are significantly improved.

owing to the different handling capacity, we have severl series model of the decanter, The smallest one is GNLW-224, GNLW-364, GNLW-454,GNLW-554, GNLW-654, and the biggest one is GNLW-764.

All parts directly touch to material are made of stainless steel

The bowl of T series centrifuges is make from Duplex Stainless steel SS2205 by centrifugal casting which is higher than SUS304 or SUS 316

Flexible pond depth adjustment for different material separation

The air-operated spring for assisting open of the cover with safety locking system

The main parts are made by centrifugal casting and die forging process to avoid intergranular corrosion and incomplete residual stress release caused by traditional welding process.

The main material of the screw is duplex stainless steel SS2205, SS2304 or higher.

Continuous and automatic operation can minimize labor costs, easy in installation and maintenance
