GN BIG BOWL DECANTER CENTRIFUGE FOR OVERSEAS MINING TAILING DEWATERING PROJECTS

This week GN completed a big bowl decanter centrifuge for oversea mining tailing project. The decanter centrifuge will be installed in container for easy transportation. The system includes 2 containers installed up and down.

In this order, customer has choose the largest model GNLW764 of GN company, Which come with 30 inch bowl diameter for large flow requirement on site. Take the inner parts protection of the decanter centrifuge consideration, we choose tungsten material plate and bushing for the decanter on screw prospeller blade, which will extend the service life of the equipment.

This GNLW-764 decanter centrifuge is a solid-liquid separation equipment, which come with 131 inch bowl length, and Max speed  is 2650RPM, the material of screw is duplex stainless steel 2205, we also choose the tungsten carbide tiles protection.

At the same time, the centrifuge equip with stainless steel VFD control panel, which can make the service life more longer. And the famous brand electric components make the after-sales more convenients. you Can buy them locally.

For more information on the mining tailing dewatering centrifuge, please feel free to contact GN Separation.

GN sludge vacuum pump

Recently GN completed 2 set sludge vacuum pump, they will be arrange to the oversea customer as soon as possible. This order is engaged in the cleaning service of Storage tank.

GN sludge vacuum pump is a fully pneumatic converying equipment that need to contact a air compressor. GN have 3 models for sludge vavuum pump, GNSP-40, GNSP-20, GNSP-10. For this order, customer have choose the biggest model, which with more suction distance up to 50 Meters, discharge to 500-1000 Meters. The transferred solids size maximum is 75mm, sludge solids content up to 80%.

 

The handling capacity of model GNSP-40B is 40M3/H(for clean water), it equip with 4” inlet/outlet size quick joint, the request of the vacuum degree is 85Kpa/25 inch HG(mercury Column), and the air demand is 17M3/Min(600CFM).

For the different material to process,we supply different material of the sludge vacuum pump, such as carbon steel and SUS 304 stainless steel and SUS316 stainless steel.

The control cabinet is Pneumatic Control, for GNSP-40B we have both Automatic and Manually, for more information, please contact GN.

GN decanter centrifuge

Three-phase centrifuge is mainly used for solid-liquid-liquid separation, i.e., the simultaneous separation of a solid phase (with the highest specific gravity) and two liquid phases with different densities.

Under the action of centrifugal force, the material forms three relatively stable layers, starting from the drum wall inwards in the order of solid-phase layer, heavy-liquid layer and light-liquid layer. The solid phase layer moves towards the small end of the drum driven by the screw conveyor and is discharged from the slag discharge port. The heavy liquid layer and light liquid layer flow along the aperture between the spiral blades to the big end of the drum, and then discharged from different outlets to achieve continuous three-phase separation.

There are GNLWS-364,GNLWS-454,GNLWS-554 model, GN centrifuge widely used in the field of solid-liquid-liquid separation. According to different industries and material conditions, GN can provide matching solutions. For more information about decanter centrifuge, please feel free to contact GN.

 

 

GN Screw Press Unit for Overseas Municipal Sludge Dewatering

Recently GN has completed 2 sets dewater screw press, later it will be arranged to transportation to overseas customer for Municipal Sludge Dewatering.

2023.08.10 sewage sludge dewatering screw press

Screw press is very common sludge dewatering screw press machine, this order will be used for  municipal wastewater treatment plants, the  sludge dewatering machine is commonly used to handle sludge dewatering and subsequent treatment of stabilised sludge. It can drastically reduce the water in sludge and reduce the cost of subsequent treatment and disposal.

It consist of control cabinet and flocculant mixing tank, with compacting structure small floor space. Dewatering machine is basically in closed operation, stable and timely treatment, reduce the site odour to a large extent, improve the working environment of workers. to achieve fully automatic 24-hour operation, reduce the operator’s labour intensity.

Advantage of dewater screw press machine

High efficiency: Stacked screw sludge dewatering machine has high dewatering capacity, which can dewater sludge with high water content quickly in a short time and improve the processing efficiency.

Space-saving: Compared with the traditional equipment, the stacked-screw sludge dewatering machine has a compact structure, occupies little space, and is easy to install and move.

Simple operation: the equipment is easy to operate, only need to adjust the parameters through the control cabinet, maintenance is also convenient.

In conclusion, dewater screw press is a highly efficient and easy-to-operate equipment, which concentrates and separates the sludge to solid state through mandatory dewatering, thus effectively reducing the cost and complexity in the process of sludge treatment and disposal.

 

GN decanter centrifuge

GN decanter centrifuge

The use of high-speed rotating drum generates centrifugal force to retain the solid particles in the juice suspension in the drum and automatically discharged to the outside of the machine under the action of force, while under the action of centrifugal force, the liquid in the suspension is thrown out through the settling medium, drum slag discharge port, so as to achieve the purpose of liquid-solid separation.


GN decanter centrifuge has the incomparable price advantage of similar products, and the machine is designed with reliable technology, stable performance, simple structure, easy maintenance, small footprint, automatic, closed continuous operation of the separation advantages.

Working principle:
The purpose of separation is to separate the solids in the mixed fluid with a specific gravity greater than that of the liquid-phase fluid from the liquid-phase fluid.
When the mixed fluid inlet into the high-speed rotation of the drum body cavity, mixed liquids in the specific gravity of the solids, under the action of centrifugal force, rapid settlement to the inner wall of the drum, by the spiral pusher from the solid-phase exit out of the drum body; while the specific gravity of the liquid phase is small in the centrifugal force of the formation of the inner layer of the liquid ring, through the liquid-phase overflow port out of the drum body. The drum and the spiral pusher operate at high speed at the same time, due to the existence of a certain speed difference between the two, making the solids settled on the drum wall uninterruptedly by the spiral pusher pushed to the liquid outlet discharge, the whole separation process is continuous.
