Recently, GN has completely the production of the solid vacuum pump, and has carried out testing before leaving the factory, and will send to the customner's work site soon.

GN solid vacuum pump is completely pneumatic conveying equipment, the air comperssor is necessary on site. GN solid vacuum pump can be used in many industries to slove material transportation problem and provide users with effectives solutios. With special struncture design, it can be used at tough environmental for solid transfer, high working performance and less maintenance. The pump can transfer ,aterial with high gravity and high density, solids content max up to 80%. 

According to different working conditions and transport capacity, GN solid vacuum pump is divided into three modes, GNSp-10B, GNSP-20B and GNSP-40B. GNSP-40B is often favored by users because of its strong suction and discharge pressure, which can better achieve the purpose of mateiral transportation.

GN Company is a professional manufacturer of Decanter Centrifuge for about 10 years, and now has capability of manufacturing decanter with bowl size from 220mm to 760mm.

In the production process, there are different process requirements such as dehydration, clarification, concentration, classification and separation. The essence of dehydration and clarification is to separate the solid and liquid in the suspension from each other. Dehydration is to remove the liquid phase in the solid phase, and clarification is to remove the solid phase in the liquid phase. Concentration is to increase the content of solid phase in solution. Grading is to divide the particles with different particle sizes in the suspension into two groups of particle components greater than D and less than DN based on a certain particle size D and D. Separation generally refers to two kinds of interaction For the separation of non-phase and solution phase, the fruit liquid and liquid phases are continuous phases, so the separation is only related to their density difference; If one phase is continuous and the other phase is divided, that is, the other phase is dispersed in the continuous phase in the form of droplets to form an emulsion. In this case, the separation of liquid-liquid two phases is related not only to the density difference of the two phases, but also to the droplet diameter of the dispersed phase.

A large amount of liquid phase, a small amount of solid phase, and the particle size of solid phase is very small (1o μ M) or amorphous mycelium, horizontal screw disc or tubular centrifuge can be selected. If the solid content is less than 1% and the particle size is less than 5rm, the tube type or zigzag type manual slag discharge can be used to separate vanadium. If solid content ≤ 3%, particle size < 5 μ m. Disc piston slag separator can be selected. The separation factor of tubular separator is high (f ≥ 1000, the separable particle size is about 0.5m. The finer particles have higher clarity, but the single processing capacity is small. After separation, the solid dry slag is close to the inner wall of the drum. During slag removal, the machine needs to be disassembled and cannot be produced continuously. In order to facilitate slag removal, there is a plastic paper drum lined with a thin sea on the inner wall of the drum, which can be pulled out during slag removal. The separation factor of the disc manual slag removal separator is also high (ft = 1000), due to the disc combination, the settlement area is large and the settlement distance is small, the clarity of the obtained clarifier is high, and the treatment capacity is larger than that of the tubular centrifuge, but the separated solid phase is also deposited on the inner wall of the turning basin, so the machine needs to be removed regularly for slag removal, so it cannot be produced continuously.

GN Company is professional manufacturer of Decanter Centrifuge, and here is a brief introduction about the technology of Decanter Centrifuge.

Compared with other separation machines, centrifuges can not only obtain solid phase with low moisture content and liquid phase with high purity, but also have the advantages of small volume, good sealing, continuous operation and automatic remote excavation. Therefore, centrifuges are widely used in chemical industry, petrochemical industry, petroleum refining, light T, medicine, food, textile, metallurgy, coal, beneficiation, shipbuilding, environmental protection, military industry and other departments, Such as coal powder recovery in wet coal mining; Purification and reuse of drilling mud for oil exploitation; Enrichment of uranium isotopes; Sludge thickening and dewatering of sewage treatment; Refining of petrochemical products; Antibacterial cable, extraction of pesticides; Manufacturing of milk, yeast, beer, fruit juice, granulated sugar, orange oil, animal Cypress oil, rice bran oil, starch and other foods; Fabric fiber dehydration; Centrifuges are required for the purification of lubricating oil and fuel oil. It can be seen that centrifuge has become widely used separation equipment in all sectors of the national economy.

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

GN Company is a professional manufacturer of Decanter Centrifuge from China Mainland, and now it has supplied Centrifuges to more than 30 countries, including Canada, USA, Brazil, Argentina, Peru, India, Singapore, Malaysia, Philippines, Vietnam, Russia, UK, Portugal, Poland, Holland, Germany, Nigeria, Egypt, etc.

GN Company has a team of professional engineers with rich experience on centrifuge technology, here are some items shared by them.

The torque of the rotating shaft is too large. The reasons and solutions are as follows:

(1) The amount of mud entering is too large, and the amount of mud entering should be reduced.

(2) The amount of inflowing solids is too large, and the amount of mud entering should be reduced.

(3) The speed difference is too small, and the speed difference should be increased.

(4) If the gearbox fails, it should be refueled and maintained in time.

Excessive vibration of the decanter, the reasons and solutions are as follows:

(1) If the lubrication system fails, it should be repaired and eliminated.

(2) The rotation of the drum is unbalanced due to the unclean washing, and it should be stopped of feeding into the mud, and clean with clean water.

(3) The machine base is loose and should be repaired in time.

The energy consumption increases and the current increases. The reasons and solutions are as follows:

(1) If the energy consumption suddenly increases, the mud outlet of the decanter may be blocked.

Clean up after downtime.

(2) If the energy consumption gradually increases, there may be accumulated accumulation between the drum and the casing. A certain amount of sludge thus hinders the operation of the drum.
