Since GN’s establishment from 2006, its solid control equipment and mud recycling system have been sold to more than 60 countries. GN’s mud recycling system can be applied in many areas, such as oil and gas drilling, diamond drilling, HDD, tunnel boring, piling, dredging, etc. Today we will discuss one application of the mud recycling system based on one case study: the project in London.

Just several months ago, GN Solids Control sold one set of mud recycling system to a UK customer for civil works. This system consists of a double deck shale shaker and a decanter centrifuge. The shale shaker is used for coarse separation to eliminate the large size solids. The screens on the upper deck will have smaller API number than the lower deck, which means the lower deck screen could separate finer solids than the upper deck screen. Then the processed fluids will drop to the tank and then pumped by a screw pump to the decanter centrifuge for further separation. The decanter centrifuge can separate the solid size up to 20 microns. The centrifuge is built tough and need less maintenance during normal operation. The bowl is made of duplex casting 2205 stainless steel, the bearing is made by world famous SKF, the screw conveyor and discharge port are protected by tungsten carbide tiles. There is also tough cover the spring to protect the decanter centrifuge during transportation. And after this separation, the mud could go back to the system to be reused again. This will be very environmental and cost effective. GN can customize the mud recycling system according  to customer’s different requirement and give customer the best solution.

GN Solids Control is an international company with its solid control and waste management business spanning all around the world. Established in 2007 in China, it’s always striving to provide the good quality product to the customer and help them saving cost. In 2014, GN Solids Control subsequently established its overseas office in US and Russia, to better serve the local customer and provide them the quick delivery and excellent after sales service. Now GN not only manufacture every single solid control equipment, but also can provide the customers with solutions and solid control system.

The liquid mud system is one of its systems which mainly used in onshore or offshore to keep the mud properties as good as possible during the mud is circulating in the wellbore. The liquid mud system is mainly composed of the following equipment, shale shaker, mud agitator, mud gun, centrifugal pump, mud mixing hopper, decanter centrifuge and various kinds of mud tanks. The type of mud tanks includes oil based mud tank, water based mud tank, base oil tank, barite tank, water tank, mud mixing tank and bulk tank. Each tank has its own special functions and will be deployed in different operation situations. GN’s shale shaker is mostly in linear motion and is used for the coarse separation. It mainly separate the solids by its size by the screen. For the screens, GN now can manufacture its OEM screen with GN brand, also it can manufacture some famous replacement screens, such as DERRICK, MI-SWACO and BRANDT. Now GN can manufacture and supply all the components with high quality and low cost.

That’s the basic introduction of the mud system. Hopefully you will be interested in it. GN has many more solid control systems, they can be used in different operational situations and help you achieve your target easily and cost effectively. Welcome to visit and please send your inquiries to

Since GN’s establishment from 2007, its solid control equipment and mud recycling system have been sold to more than 60 countries. GN’s mud recycling system can be applied in many areas, such as oil and gas drilling, diamond drilling, HDD, tunnel boring, piling, dredging, etc.  Please allow me to introduce to you our Oil sludge treatment system.

GN’s long view for the future market has lead us into a new ago of products development. After many years of research and development, in the year of 2016 we brought our Oil Sludge treatment system to the world. It contains our vacuum pump, mixing tanks with 3 stages separation equipment, and oil and water recovery tanks. It can be used for waste oil sludge/sand in raw oil tank bottom, from refinery plant, and from a drilling rig. In currently market there are few company can offer the entire system to client with customization services, and their unit cost a fortune to purchase. It is very important that to recycle oil as much as possible with a low cost.  We have made good business cooperation with world renowned service company like Baker Hughes. Together we service the largest oil company in Kuwait—KOC Kuwait Oil Company.  But we didn’t stop there, with different client’s different job requirements, GN offers different models of oil sludges treating system as well as Thermal Desorption Unit.  After treatment, client company will be able to recover oil and water for re-sale and re-use porpoises. Creating extra value for used to be wastes—oil sludge.

In this very competitive market, we offer many different systems to satisfy different industries, different clients. We will keep researching new frontier, new equipment to keep GN’s leading position. That is the basic introduction about the mud recycling system, If you have some further interest, welcome to visit and please send your inquiries to .

GN Solids America LLC manufacture oil drilling equipment including shale shakers and its wear and tear  parts. Shale shakers is the solids-filter machinery that remove drill cuttings from the drilling mud that is used for digging holes into the earth. Filtering the solids in drilling mud is an important component of the operation cost of drilling, so research and development into shaker functioning is ongoing.

GN Solids America’s shale shaker design – Shale shakers consist of large, flat wire mesh screens for  filtering or sieves of various mesh sizes that shake or vibrate the drill cuttings.  The commonly filter across and off of the shale shaker screens as the drilling fluid (mud) flows through them and back into the drilling fluid system. This separates the solid drill cuttings from the fluid so that it can be re-circulated back down the well bore for keep the drill bit functioning.

Shear pump contain following parts: impeller, vortex shell, transmission shaft, belt pulley, belts, motor and bearing.  The impeller of the shear pump is totally different compare with other pumps due to its function, shearing the objects.  The impeller which contain high cutting efficiency that have 5 structure parts: axial flow turbine, reservoir, wheel for pump, plenum chamber and cutting plates. The whole parts structure in stainless steel that has compact structure for it.

The flow axial turbine is for fluid with displacement and for pump and the tank.

The fluid flow through the pump wheel is discharged into the vortex shell, and the half of fluid is absorbed by reservoir. The fluid flowing through the pump wheel is parallel to the shear plate flow and has a high flow rate.

The fluid mixed with the shear pump wheel in a higher flow rate, and the high speed rotation of the shear plate is serrated, and the fluid that contain solid is sheared. By this way of process, the fluid flowing through the impeller, subjected to multiple shear.

The seal of the Shear pump with a very reliable mechanical and to make sure no leakage.

The pump turbine is mounted on a specific base plate and is move by a belt pulley. A  V belt in narrow design drive an IEC explosion proof certified motor, and a mixing hopper with a size suitable for use with the shear pump is composed of a completed shear and hydration system.

GN Solids America LLC’s JQB series shear pump with specific purpose of whole solids control system that can meet all system operators drilling fluid preparing for well drilling. It can makes the mud to obtain good rheological properties and reduce the cost of drilling as much as possible.
