GN Decanter Centrifuge

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.

For more information about sludge dewatering screw press, please feel free to contact GN separation.

GN screw press unit also named screw press sludge dewatering machine, it’s a kind of economic and environmental friendly sludge dewatering equipment.

GN dewatering screw press is composed of fully automatic control cabinet, clocculation modulation box, sludge thickening and dewatering device and liquid collecting tank. It’s widy used in sewage treatment project of municipal, food, pharmaceutical and other industrical.

The equipment model in this order is GNDL301, the inner diameter of the dewatering screw assembly is 300mm, and the material is SS304 stainless steel, Manifold inlet and outlet form is flange.

Actually, In terms of material selection, stainless steel 304 is selected for the parts of GN screw press machine in contact with sludge in order to aviod any corrosion, according to the specifical requirements of customer or specific material conditions, higher grade stainless steel material can also be selected, for example SS316 or duplex stainless steel 2205.

The equipment shell can be opened from the top to facilicate the operator to check the opreation status of the dewatering screw and ensure the stable operation of the equipment.

For more information, please contact GN to get more details.

GN Solids Vacuum Pump is fully powered by compressed air to transfer solids, powder, slurry, sludge etc. GN Solids Vacuum Pump is a compact, robust, and efficient pump which is capable of recovering material via 25″hg of vacuum and delivering the over 500 meters. GN Solids vacuum pump single unit is available in 10 m3/h, 20 m3/h and 40 m3/h. GN also is capable to design and make Group Pump Unit in one skid.

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
