on . Posted in News


GN Solids Control successfully exhibited in Global Petroleum Show the GPS show in Calgary Canada this June 12-14th. Ths GPS show is one of the largest Oil and Gas Equipment and Technology show in Canada. It will be hosted in Calgary every year and welcome clients from many different countries to be at Calgary and trying to discuss about Canadian market updates, global market impacts, industry direction and creating new business market.  Even though the industry is still not at its upturn, GN still presented its strength in the Canadian market and demonstrated its latest technology and products.

During the show GN has shown cased out brand new equipment to our products line---Our Oil Sludge Vacuum Pump. It works with only air pressure and no electronic components. Fits jobs in different sizes, different requirements. For example, we can just simply lower down our pump into an oil tank to suck all bottom sludges from the tank and fully operational with just an outside air pump. 

During the show we are also going to show case our replacement screens for major shakers in the market. This year GN made a lot of effort in the improvement for the screens. GN launched its second facility specially for making the shaker screens of composite frame. Now GN has composite frame replacement screens available for MONGOOSE, KING COBRA/ VENOM, FLUID SYSTEM.  A good solid control process could increase the rate of penetration, reduce the wear and tear of the drilling equipment, such as the pistons, liners of the mud pump and allow for better hole cleaning.

That’s the brief introduction about the mini decanter centrifuge. Hopefully it will be useful to you. GN has many more solid control equipment, they can be used in different operational situations and help you achieve your target easily and cost effectively.

the mud recycling system specially designed for micro tunneling and piling

on . Posted in News

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.

Unusual sound happen on operation of decanter centrifuge

on . Posted in News

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.
