Vertical Screen Scroll Centrifuge
Monday, 15 August 2016 01:24

When drilling waste management becomes a big problem of oil gas industry. The Vertical Screen Scroll Centrifuge was brought to this application, the US manufacture improved the product and used it for drilling waste, then it became a standard product of drilling waste management. After GN Solids Control march into manufacturing the verticle cuttings dryer, now we are going to improve the orignal design of Vertical Screen Scroll Centrifuge, with experience of verticle cuttings dryer, and experience in drilling waste management.

The GN Vertical Screen Scroll Centrifuge uses centrifugal force to dry wet coal. A stainless steel screen bowl traps wet coal and accelerates them up 900RPM with G force to 420G. This G force is higher to most of GN competitors which will give better separation. Liquid is forced through the screen bowl openings, the openings of the screen is optional in different sizes, while “dry” coal are extracted by the angled flights or knives attached to the rotation cone, which rotate slightly slower speed than the bowl and screen. This differential speed is to push the dry solids or coal to discharge from the bottom of the screen centrifuge.

Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl of the centrifuge, which is crucial for proper operation.

Contact GN freely to discuss with us how to improve vertical screen scroll centrifuge for mining projects, if you are in the mining industry, and want to have a better product with better result.

We have been staying on the same business, solids control, focusing on, and making good products. Now we have well known shale shaker, compact mud system, and multi solution for drilling waste management. One of the main product is Decanter Centrifuge.

Some client prefer just call it decanter, some may only refer it as centrifuge, never mind this is our key product. And more and more professional production line keep us in the front of decanter centrifuge suppliers.

Not only the oilfield clients accepted us, and feedback that our equipment is even better than EU /US similar products. Other applications, more and more clients asked us for a solution, they bought our products to test their own ideas, so we hire more professionals in for other applications, to offer our client more professional solutions, not only good products, like we always doing.

High Standard Decanter Centrifuge to Europe
Monday, 18 July 2016 14:54

 

When we discuss about made in China, there is some other stories we always heard, British laughed at German products before. The world do not like products made in Korea, made in Japan. While now made in German is sort of standard, and made in Korea and Japan means higher quality. So it is just now turn for China to be laughed. Even lots of people did not improve the quality themselves quite well, they think this is a trend. We never take it an easy way, GN keep focusing on high quality products, but we never take it as granted, as all GN people is working on it.

Also according this logic, accepting by Europe client is also sort of self-approval. Now more and more clients from Europe choose our products. Though it starts from Europen people working all over the world, but the EU local comapnies are now moving on to GN. Except the system working in central London http://www.gnsolidscontrol.com/drilling-fluids/gn-decanter-centrifuge-working-in-landon-uk-for-construction-industry, now a big company from UK is testing GN centrifuge. 

DNV CE centrifuge

The model of the centrifuge is GNLW363CG-VFD. LW in Chinese means horizontal spiral type centrifuge that is typically used in oil industry. C tells the third generation of GN centrifuge shows in the past nearly 10 years, GN was always keeping on upgrading and improvement. And GN keep updating our equipment, to keep basic sourcing / tracing, we are using different word to make it different.

The G means this model is a high configuration with bowl material of duplex stainless steel 2205 which is much better than other China based manufacturer who still use SS304. Not only the material, GN is making different product from design, and details.

Inside the bowl, screw propeller are made of SS316 and protected by 4mm thick tungsten carbide tiles. Comparing with other China manufactures’ spray welding 2mm protection, GN’s screw propeller has much longer lifetime that would greatly reduce the future maintenance cost. For more flexible operation purpose, the client chose the variable frequency drive for different working speed.    

Keep tune on GN production, find more surprise.
