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.

The feed enters the bowl through a stationary inlet tube and is accelerated smoothly by an inlet distributor. The centrifugal force that results from the rotation then causes sedmentationof the solids on the wall of the bowl.

Separation takes place in a horizontal cylindrical bowl equipped with a screw conveyor.

The conveyor rotates in the same(adverse) direction as the bowl, but slightly slower(faster), thus moving the solids towards the concial end of the bowl. The cake leaves the bowl through the solids discharge openings into casting.

The separation process runs through the bowl entire cylindrical section, clarified liquid is separated by adjustable overflow plate.

Recently, GN has completed the productions of vacuum pumps, it will sent to the customer’s work site very soon.

GN sludge vacuum pump is completely pneumatic conveying equipment that can be applied to the conveying of various material. GN solid vacuum pump has a compact tructure, which is convenient for on-site layout. There are 3 modesl, GNSP-10B, GNSP-20B which equip with wheels, and GNSP-40B. When pump working, the suction and discharge process conduct alternatively. GNSP-40B can work in either automatic mode or manual mode, GNSP-10 B and GNSP-20B only have automatic mode.

As for GNSP-40B, the max capacity is 40m3/h (For clean water), and vacuum degree is 85Kpa/25 inch HG（Mercury Column), the max solids size is 75mm, for the max distance is 50M.

GN solid vacuum pump has certain advantages in conveying loose materials with high viscosity, so it is often used as the feeding equipment in the waste oily sludge treatment system.

 

In addition, GN solid vacuum pump has other typical applications, such as the transportation of grain particles, the transportation of mining slag, and the cleaning of sludge pits and so on.

Recently GN has completed one set GNLW364 sludge dewatering centrifuge and will send  them to overseas customers.

As is well known, decanter centrifuge is commonly used solid-liquid separation equipment, and it is also widely used in the food industry. The suspension to be treated needs to meet the density difference between the solid phase and the liquid phase, so that the solid-liquid separation can be effectively carried out under the action of centrifugal force.

The GNLW364FT sludge dewatering centrifuge is an effcient and environmentlly friendly sludge dewatering equipment developed by GN company. It equip with 30KW main motor and 7.5KW back drive motor, in order to Saving electricity.It also come with a VFD control panel.

Additionally, GN usually provides a VFD control cabinet for the centrifuge, and frequency converters are installed inside to control the speed of the bowl and the screw. According to the matched feeding flow, the feed pump frequency converter will also be installed inside the control cabinet. The VFD cabinet of GN decanter centrifuge is equipped with a PLC. The operator can view the equipment operation on the touch screen and control the equipment operation through the interactive interface of the panel.

Recently GN have completed a tubular centrige and already arrange to send to the overseas clients for Microbial fermentation broth separation.

This clients was a Middle East Biotechnology Company, they choose the model GNGQ142 to do Microbial fermentation broth separation, it equip with the cooling coil, which can keep the tempearture of the fermentation at lower statue and maintain the activity. The rotor material is 316L, equipped with cooling coils to maintain the working temperature of the material, including a stainless steel variable frequency control box, with adjustable speed, speed display, and temperature display.

The device is also equipped with a frequency conversion control cabinet, which can easily adjust the speed and display the speed and temperature in real-time. This intelligent control method makes operation more convenient, while also providing customers with more flexibility.

GN high speed tubular centrifuge products have a wide range of application areas, for more detail of the tubular centrifuge, pls feel free to contact GN.

This week, GN completed the assembly a unit dewater screw press, which later will be sent to overseas clients which located in America for wastewater treatment.

The screw press unit is a compact sludge dewatering equipment with low energy consumption and low noise, which can achieve a high degree of automation control in the process of use.

The dewater screw press machine is composed of fully automatic control cabinet, flocculation modulation box, sludge thickening and dewatering devie, and liquid tank.

The screw dewater press mainly divided into two parts in structure, namely flocculation conditioning tank and dewatering assemble. The main body material is stainless steel 304, with high structural strength, good corrosion resistance and easy maintenance.

In this order, the customer choose the model of GNDL301 which equip with screw diameter 300mm and 1 piece 0.55KW screw motor and a agitator which power 0.4KW.

Flocculation is an essential process in the working process of the dewater screw press, we also can equip a set of polymer dosing unit according to your request.
