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.

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.

 

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 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.

Decanter Centrifuge Manufacturer in China

Compared with other separation machines, centrifuges can not only obtain solid phase with low moisture content and high-purity liquid phase, but also have the advantages of small size, good sealing, continuous operation, automatic remote control, etc., so they are widely used in chemical industry, Petrochemical, petroleum refining, light industry, medicine, food, textile, metallurgy, coal, mineral processing, shipbuilding, environmental protection, military and other departments, such as the recovery of pulverized coal for wet coal mining; the purification and reuse of drilling mud for oil mining; uranium Concentration of isotopes; sludge concentration and dehydration of sewage treatment; refining of petrochemical products; extraction of antibiotics and pesticides; manufacture of milk, yeast, beer, fruit juice, sugar, orange oil, animal and vegetable oil, rice bran oil, starch and other foods; The dehydration of fabric fibers; the purification of lubricating oil and fuel oil need to use centrifuges. It can be seen that the centrifuge has become widely used separation equipment in various sectors of the national economy.

The application functions of the centrifuge mainly include: dehydration, clarification, concentration, classification, separation and so on. Different centrifuge models must be selected according to different material characteristics and separation requirements, which leads to the problem of centrifuge selection. In the actual production process, due to the selection of suitable separation equipment for some projects, the process is simple, the energy consumption is reduced, the product quality is improved, and good economic benefits are obtained; but there is also improper selection of centrifuges, which makes the production process unable to proceed normally. , resulting in greater economic losses. Therefore, in the engineering design and technical transformation, the problem of how to correctly select the centrifuge has been recognized and valued by the majority of engineering and technical personnel.

GN Company’s Decanter Centrifuge for Wastewater Treatment

GN Company has been focus on manufacturing Decanter Centrifuge for about 10 years. Now it has three factories in China Mainland, and two subsidiaries outside China, one is in the USA, and the other one in Russia.

GN Technical Engineers have rich experience on research and develop the centrifuge technology, and here are some of their experience about analysis and elimination of abnormal problems.

1. The separation liquid is turbid, and the solid recovery rate is reduced. The reasons and solutions are as follows:
(1) If the thickness of the liquid ring layer is too thin, the thickness should be increased.
(2) The amount of mud entering is too large, and the amount of mud entering should be reduced.
(3) The speed difference is too large, and the speed difference should be reduced.
(4) The inflow solids are overloaded, and the amount of mud entering should be reduced.
(5) The screw conveyor is seriously worn and should be replaced.
(6) The rotating speed of the drum is too low, and the rotating speed should be increased.

2. The solid content of the mud cake decreases. The reasons and solutions are as follows:
(1) The speed difference is too large, and the speed difference should be reduced.
(2) The thickness of the liquid ring layer is too large, and its thickness should be reduced.
(3) The rotating speed of the drum is too low, and the rotating speed should be increased.
(4) The amount of mud entering is too large, and the amount of mud entering should be reduced.
(5) The dosage of dry sludge should be reduced if the dosage of conditioning and tempering is excessive.
