Recently GN Separation & Conveying Equipment Company release new website, http://www.gnseparation.com/ , welcome to check our equipments information and industry news from our website. For the solids control equipments and drilling waste management equipments and oil sludge separation system information, pls check our website www.gnsolidscontrol.com, also you can check the working video and project news from this website.


Our major separation and conveying equipments including:
1) Decanter centrifuge for waste water treatment, mining & industrial sludge/ tailings treatment, chemical treatment. The bowl size available is 9 inch bowl, 14 inch bowl, 18 inch bowl, 22 inch bowl, 30 inch bowl with different treating capacity, and each bowl size have ratio available for 3 or 4 or 4.2. By the different requirement for the discharged solids moisture and discharged water clearance, different ratio ( bowl length / bow diameter) will be choosed, and the bowl angle is customized for different material.
2) Conveying Equipment: Screw Conveyor, Bucket Elevator for bulk material handling.


3) Transfer pump: Centrifugal pump, solids vacuum pump, screw pumps. The vacuum pump is widely used to transfer the cement, animal waste, oil sludge, drilling cuttings, drilling fluids, oil contaminated soils and other materials. It is 100% air operation pump without electricity power supply, it is ideal equipment to work in the electricity limit area. The air compressor is required to provide air supply for the vacuum pump operation. Centrifugal pump is interchangeable with world famous brand centrifugal pump installation and parts, it can be used as mixing pump, feeding pump of desander, desilter, trip pump, super charging pump, transfer pump of oil sludge. Screw pump is normally as feeding pump of decanter centrifuge and flushing pump of vertical cuttings dryer.

This week GN solids control shipped one batch of mud transfer pumps and mud agitators to Asia client. The centrifugal pumps are 100% interchangeable with world famous brand centrifugal pump, we can provide bare pump head and all the parts and the whole centrifugal pump with motor, skid, coupler, and control panel.


Features of GN centrifugal pump:
1. The impeller and pump casing is made of hard ductile iron alloy, which is abrasion resistant material and can longer the working life of the centrifugal pump. Different with the other competitors grey steel material, it is easily break.


2. The bearing is top brand bearing for reliable operation, the client do not need to repair the pump time and time and delay their operation.
3. The mechanical seal is also an important wear parts for the centrifugal pump, for better sealing and zero leakage and longer working life.
4. The mounting skid of the centrifugal pump is made from casting instead of welding to provide the reliable operation and less vibration for longer working life.


Mud agitator is one of the mixer equipment to be installed on top of the mud tank, together with tank bottom mud gun for better agitating and mixing of the drilling fluids in the mud tank, to prevent the drilling fluids to be accumulated in the tank bottom. The direct connection mud agitator design is with compact size, convenient operation, maintenance and customized agitator shaft length and impeller size for better performance.

Below is the photo of GN drilling waste management system working for CNPC project successfully, the client is satisfied with the performance, the oil on the cuttings is below 5%, it can meet the environmental regulation for landfill or for disposal. If the user need the OOC to be lower than 1%, we have Thermal desorption unit, the drilling waste management system can be used before TDU, it can save energy and save the operation cost of the TDU for the user.


The drilling waste management system consists of VFD decanter centrifuge, vertical cuttings dryer, screw pump for feeding the centrifuge, screw pump as flushing pump of vertical cuttings dryer, mud tank for collection of the centrifuge fluids.
The features of the GN decanter centrifuge: The goods quality and proper design can ensure the goods separation performance of the decanter centrifuge.


1) All the centrifuge bowl is made of duplex stainless steel 2205 or 2304, which is better than SS316 and SS304, the other components are made of SS316. The screw is made of SS304 by heating treatment.
2) The solids discharge port and fluids distribution port is interchangeable and protected by tungsten alloy.
3) The bearing is SKF brand bearing to ensure the longer working life.

This week GN solids control shipped one batch of solids control equipments to Russia, the client inspect the equipments in our factory in Beijing before dispatch to Russia. We welcome all the clients to visit our factory before order and after order before delivery.


The solids control equipments they ordered including linear motion shale shaker, mud cleaner, decanter centrifuge, centrifugal degasser, this is their repeat orders since 2017, they keep repeating orders every month during the past years, and make mud tanks system locally. Sometimes they replace the old equipments from their existing rig solids control system.


The shale shaker, mud cleaner, vacuum degasser/ centrifugal degasser, decanter centrifuge are our main products and the most popular products, we have many options for decanter centrifuges with different size from 9 inch to 30inch for different applications, for each bowl size, we have 2 models with different ratio. For 9 inch bowl size centrifuge, we have GNLW224D and GNLW224E-VFD, for 14 inch bowl centrifuge, we have GNLW363C, GNLW363-VFD, GNLW364C-VFD, for 18 inch bowl centrifuge, we have GNLW452, GNLW453C-VFD and GNLW454D-VFD , for 22 inch bowl centrifuge, we have GNLW553C-VFD, GNLW554D-VFD for option, for 30 inch bowl centrifuge, this is the max centrifuge we produced at present, we have GNLW764D-VFD centrifuge, this is mainly for tunneling project which need a huge volume of mud.


The linear motion shale shaker, we have 2 panels, 3 panels, 4 panels and double deck shale shaker for option, all the shaker screens are produced by our own workshop with our brand GN solids control, the composite material shaker screens produced by GN has been approval by many clients in the world for their oil & gas drilling rig.

10 units of shale shakers are shipped to India drilling company this week, they also produced one set of solids control shale shaker tank ready for shipment, including 3 units of same model shale shaker, 1 unit of mud cleaner, 1 unit of vacuum degasser, 1 unit of mud gas separator, 2 units of centrifugal pumps, and necessary mud agitators, mud gun, and 1 unit of mud tank.


GNZS703F-HB shale shaker is one of the best sold model shale shaker, with 3 panel composite material frame shaker screens, we produce OEM shaker screens in GN own shaker screens workshop. Except for the OEM shaker screens, we also produce durable composite material shaker screens for world famous brand shale shaker, like Derrick FLC 500 series, FLC 2000 series, hyperpool, D600, etc, Brandt King Cobra / Venom, VSM300, MI-SWACO Mongoose PT,MD 2/3, FSI, etc. Compared with the steel frame shaker screens, GN made composite material shaker screens with 20% larger effective screen area, the working life is much longer, the storage period is up to 5 years.


The mud cleaner is the combination of desander cone, desilter cone, underflow shale shaker, the treating capacity is different by using different quantity desander cone and desilter cone. GNZJ703F-1S8N with 500gpm capacity with 1ea desander cone and 8ea desilter cone. GNZJ703F-2S12N with 1000gpm treating capacity with 2ea desander cone and 12ea desilter cone. GNZJ703F-3S16N with 1500 gpm treating capacity. The feeding pump for mud cleaner is GN made centrifugal pump , the parts and installation dimension is 100% interchangeable with world famous brand pump.
