GN Solids Control is a one of the top manufacturer for solid control equipment and mud recycling system in China. It opens business in China in 2007, and after 10 years hard working and development , its product range covers from shale shaker, desander, desilter, mud cleaner, mud gas separator, decanter centrifuge, cutting dryer, centrifugal pump, agitator, vacuum degasser, shear pump, submersible pump, etc. GN can be your one stop shop and solution provider for the solid control business. We have always eyes on better quality and customer experience, and we’ve been working hard towards that goal. We have build a factory capable of making 5000 plus screens a month, and 150 plus decant centrifuge per month also.

We are pushing our new composite framed shale shaker screens in the U.S market. It has the follow features: the steel frame part is welded automatically by robot with higher strength and better quality conformity. The injection molded plastic is mixed with imported fiberglass and it can resists high temperature up to 140 degree, and it’s tougher, more endurable and can work under higher vibration G force. . The heat press of the screens adopts the process of four side tensioning which can minimize the gap between the top and support screens and extend the life of the screens. GN’s shaker screens will be 3 layers with the API number above 60, while other screens manufacturer only use 3 layers until API number above 100. And GN’s mesh supplier is the same as DERRICK and MI SWACO’s. GN’s screen adopts the rectangular wire configuration and the wire is 50% more thicker than the square wire configuration, and it could be used up to 300-700 hours. GN’s composite screens cover GN’S OEM screen, MI SWACO MONGOOSE, BRANDT VENOM, BRANDT KING COBRA, FSI, etc. GN can also customize the screens according to customer’s requirement. All the composite screens are repairable. Comparing to steel framed screens, the non blank area of composite framed screen is 10-20% more. And the composite frame is not easily to get rusted and can be stored up to 5 years.

GND series product is the mud recycling system specially designed for micro tunneling and piling. Recently in GN’s China headquarter, one full set of mud recycling system was just finished and shipped to a domestic Chinese customer.

GN Solids Control is the world famous solid control equipment and mud recycling system manufacturer, As the leading manufacturer for shale shaker, mud cleaner, decanter centrifuge, cutting dryer, centrifugal pump, etc, GN’s brand and products are recognized by more and more international customers. GND system is comprised of a double deck shale shaker, two hydrocyclones, one centrifugal pump, one storage tank and electrical control system. The system can effectively separate the solid and liquid and reduce the solid waste content in the drilling mud, and make the drilling cuttings drier, easy to transport, environmental friendly and easy for disposal. The whole system is very compact and skid mounted, is very economic and good value for money.

The system’s first level of separation is the double deck shale shaker, when the mud goes into the lower deck of screen, the large solids will be separated from the mud the fine solids and mud will be dropped into the tank, and the mud will be sucked by the centrifugal pump into the two hydrocyclones which is working like the desander which can separate the solid size up to 40 microns. The solid separated by the hydrocyclone will drop onto the upper deck of the shale shaker, then the solids will be dried further for disposal. The clean mud after the separation by the hydrocyclone will flew back the tank and be pumped back to the wellbore for reuse and recycling. The basic configuration of the mud recycling system is one double deck shale shaker, two hydrocyclones for desanding, one centrifugal pump, one mud tank and some other parts.

GN Solids Control is a top tier Manufacturer which specializes in manufacturing solid control equipment and system. Company started its first business in 2007, and our main focused has always be quality and reliability, which can help our customers save money and variable time. And among all equipment we provide, there are three Key products that have been proved to be more rugged, durable and reliable, they are: shale shaker, decanter centrifuge and cutting dryer.

Recently, GN released its new product-GNLW363D-FHD decanter centrifuge. So today, let’s get to know what the meaning of the product name. GN of curse it is a short initial of our company full name Guan Neng, LW means it is horizontal spiral product. 363 means the bowl diameter is 360mm which equals to 14 inch. And 3 means the length of bowl is about 3 times longer than the diameter. This ratio has been specially engineered by the technician to guarantee its good performance during work. D means the 4^TH  generation of decanter centrifuge. FHD means full hydraulic driven. All the configuration is high standard which can meet most of the customer’s requirement. The bowl material is made of duplex SS 2205/ SS 2304, the screw conveyor material is made of SS 304/ SS 315 and then the surface is protected by the tungsten carbide tiles which is more endurable and reliable, and it can save customer’s money both in operation and maintenance. And the solid discharge port is also used the tungsten carbide inserts. The bearing is still used the world famous SKF. The FHD system is VISCOTHERM full hydraulic drive. The electrical control system is smart PLC control. And the coating is used the Cosco & Kansai Zinc Rich Epoxy Coating. The equipment can be used in extreme high temperature environment with heavy mud situation. And the decanter is designed and assembled on a skid, which makes it easier to move and save time and cost for transportation.

That’s the brief introduction about GN’s new fully hydraulic drive decanter centrifuge. Welcome to visit www.gnsolidsamerica.com and please send your inquiries to This email address is being protected from spambots. You need JavaScript enabled to view it.

Loud sounds made from machine now become part of occupation hazard for works who expose it in extend of time period.  It how have regulate by government  because the consideration of the machine design. 

GN Solids America LLC's decanter centrifuge is the machinery with rotating bowl and contain many number source of sounds .  The size of the machine, the speed of the rotating bowl, which is the main source of noise come from structure.  Other sound like turbulence sound and siren sound is also part of sound production from the decanter centrifuge. 

Structure sound often produce by all surfaces that directly coupled to the bowl's bearing.  The speed of rotation of the bowl, it create turbulence from the different trailing edges that produce broad spectrum vortex sound.  The siren sound is from air flow through the bowl and it produce great noise especially  at the lower harmonics of the bowl rotate frequency.

There are ways to decrease sound that produce by decanter centrifuge, some of them are:

·         Decoupling the surface of the main bearing of the rotating bowl and will reduce the amount of noise transmitted from the decanter centrifuge structure

·         Polish and smooth the bowl surface will minimize the noise produce from the edge that vortices that shed and produce vortex, turbulence noise

·         Siren sound produce because from the air flow through rotating bowl, which is the purpose to the function  of the decanter, the exit opening should be design so the noise is produce within the parts of spectrum of sound have low noise level

The sound that produce from machinery is consider health hazard if personal consistently exposure on sound that is great then 80 to 85 dB over an eight hours per day.  Excess expose of level of 85 dB during work life would result 90% of people suffer lost of hearing.  It can also damage the way of speech as well.  Which now sound regulation is the must enforce regulation.
