Category: decanter centrifuge

This month, GN will attend the ECWATECH 2023 Exhibition held in Moscow.

GN will be provided a platform for all the water treatment supplier to communication. Welcome to GN booth to get more information.

This time, GN will show the equipment as below

1.  Decanter centrifuge– GNLW series decanter centrifuge has the bowl diameter from 9 inch to 30 inch for different flow rate requirements. GN decanter is widely used in waste water treatment and other industries separation application.

2. Solid vacuum pump, it is 100% pneumatic driving and make it suitable for the harzard and explosive environment. The max particle size is 50MM, The pump is designed for both automatic operation and manually operation. Operator only needs to adjust the suction and discharge time by twisting the switch on the panel.

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

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.

Sludge Decanter Centrifuge are used for sludge dewatering without chemical conditioning, but when the sludge is conditioned with polymeric electrolytes, the solids retention rate and the quality of the liquid after centrifugation are significantly improved. The centrifuged liquid slopes back to the sludge thickener or initial settling tank. The water content of the sludge cake is approximately 70-80%. The sludge centrifugal dewatering centrifuge requires a smaller site area than a vacuum filter with the same production capacity and has lower capital costs.

The advance of the decanter centrifuge

1、Continuous automatic operation

Decanter centrifugal dewatering from pumping out sludge, injecting medicine, discharging sludge cake are automatically controlled, through the electronic control cabinet, and into the sludge pumps, dosing pumps, etc., linkage, do not need personnel to operate the equipment, the operation will not be clogging, filtering away from the bias or other phenomena affecting the safety of the process, the daily maintenance of maintenance simple, 24 hours can be continuous unmanned operation. The sludge dewatering continuous full-automatic operation is realised in the real sense.

2、Saving project investment

The decanter centrifugal dewatering machine itself has the function of sludge thickening, and it can directly deal with aerobic sludge in the aeration tank without thickening and storage unit, which reduces the overall space occupied by the sewage treatment facility and the construction cost.

3、Machine body is light and durable

Decanter centrifuge due to the direct use of mechanical centrifugal separation dewatering, without the need for large-scale body, so the machine is designed to be quite lightweight; almost all the body is made of carbon steel or stainless steel, with a long service life and durability.

 

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.

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.
