GN Solids Control is especially good at providing customized solutions for solids and liquid separation. Thousands of GN Solids standard treating equipment like shale shaker, decanter centrifuge, cuttings dryer, mud cleaner are widely used. GN Solids Control also manufactures auxiliary treating unit like premixing treating tank, which can be used to premix the high density or large viscosity oil slurry before feeding into shaker or decanter centrifuge.
Heating pipes and mud agitators are assembled on the premixing tank to dilute the slurry and keep the oil slurry from sediment. A submersible pump or screw pump will be used to feed to the backwards shaker or centrifuge. Here is one inquiry we just received for our Mexico customer.
In Mexico, I have suggested to them to add a mixing tank to their soil washing system. Please prepare a quotation for me to present to them.
The tank is similar to other tanks that you have prepared quotations.
Mixing tank with two mixers, submersible pump with shale shaker (single deck) mounted on top of mixing tank.
I am interested in keeping the height of the mixing tank as low as possible.
I want your submersible slurry pump GN80YZ50A-20 (7.5 kW) that is 1.3 meters long.
Is it possible to make the tank approximately 4.5 meter long x 2.4 meter wide by 1.5 meter high?
Because of the length of the tank, use two mixers if you think it is necessary to keep the tank well mixed.
On top of the tank, a shale shaker (GNZ703F-HB) will be used as a scalping screen for the incoming slurry flow into the mixing tank. 850 micron screens or 1,000 micron screens will be used.
An electrical panel for start/stop of the shale shaker, mixers and pump. Also, a tank level control transmitter to control the submersible pump. Ladder, railings and lights included. All electrical is 480 volt and 60 hertz.
As one of the most famous turnkey solids control and waste management system provider, GN Solids Control manufactures the following equipment, like shale shaker, desander, desitler, mud cleaner, cuttings dryer, decanter centrifuge. Wearable parts like shaker screens are also largely manufactured by GN Solids Control.
GN Solids Control manufactures more than three hundred decanter centrifuges every year for the oil and gas area. Every year, GN Solids Control received hundreds of inquiries on decanter centrifuges. Today we would like to share one of our former inquiries.
The bowl assembly is including the following 2 parts: a. cylindrical bowl (closed on one end by the liquid bowl head), b. solid bowl head at the other end. The bowl has to be featured with adjustable weirs on the liquid bowl head to permit manual adjustment of the pond depth. Index marks should be provided on the weirs to facilitate precise settings. The tapered bowl extension at the solid end forms an upward sloping beach. Solids are collected and are discharged continuously from the solid discharge outlet. In order to protect the openings from wear, replaceable wear inserts in the solid bowl head Conveyor are used.
The conveyor assembly is a hollow, cylindrical auger with axial/radial flights that receives the inlet slurry into its interior, disperses it through nozzles to the bowl assembly, and transports the solids to the solid discharge outlet. Feed nozzles are using carbide inserts, and on the edge of the conveyor there is carbide tiles provide wear resistance. Two greased ball bearings are mounted in pillow blocks.
Both ends of the conveyor are supported by GN Solids vibration switch shut-off mechanism to automatically disable operation in situations of high vibration, which is optional.
Feed Pump: The package should be included one set feed pump for the centrifuge. The feed pump is a GN 3x2x13-11 centrifugal pump or GN made variable speed positive displacement pump.
GN Solids Control has been providing decanter centrifuge for a long history. GN Solids Control has been delivered more than 200 sets decanter centrifuges to oil and gas customers. Besides decanter centrifuge, GN Solids Control also manufactures solids and liquid equipment like shale shaker, mud cleaner, cuttings dryer etc.
Every day, GN Solids Control receives some centrifuge inquiries from the world. Today we would like to share one project with you.
As we all know, GN Cleaning Centrifuge Package is used to process un-weighted and weighted, water-base and oil-based drilling fluids (muds). The centrifuge is usually fed by feeding pumps or submersible pumps.

This customer demands main components of GN Solids Control centrifuge consist of the stainless steel gearbox driven assembly, rotating assembly, fluid coupling, feed pump, electrical components such as control panels, control boxes, drive motors, vibration switches, temperature sensors, carbon steel guards, stainless steel cases, abricated carbon steel base assembly and DNV oilfield skid with lifting points for transporting. 2-years spare parts should be provided with the package in order to ensure uninterruptable operations for the centrifuge package.
While for the rotating assembly it should consist of a cylindrical bowl (bowl and heads forged of stainless steel to provide corrosion resistance for long life, smooth operation and low maintenance) and conveyor assembly as well as related components. GN centrifuge rotating bowl ends are supported by greased genuine SKF ball bearings.
