Mud agitator is a motorized mixer that is installed on the storage tank to keep fluid consist mixed with additive and avoid separation by gravity.  According to the experience of continues use on the field, the selection of mud mixer should consider to a few points:

1. Rotation speed: Operators it does not want the cuttings in the mixing process splintered more into smaller debris, so the stirrer speeds cannot be high, the energizer should choose between 50~60rpm. For more than 60rpm of mud mixer, recommended the user to take a cautious on the result of the high rotation speed.
2. Sealing: According to the feedback of use from the operator. As mixing conditions are not ideal, the drilling fluid mud agitator shaft is not suitable for the use of end face seal, the general packing seal is also hard to use. At present, the more suitable is the use of multiple sets of V type packing. It has self sealing performance and self compensation ability, and long-term maintenance adjustments abilities will not cause lubricating oil leakage problems.
3. The impeller: There is a variety of mud mixer impeller, but it must take consideration that a small diameter of the blade with high speed of mixer motor have the small amount of circulation, shear force, and therefore does not apply to the use of drilling fluid solid suspension. Therefore, the diameter of the impeller should be consider larger. Second, pay attention to the turbine type impeller has been widely used in the drilling fluid mixer, which is the best open type turbine, because there is no central disc, not to hinder the mixing of the upper and lower liquid phase of the impeller.

GN Solids America LLC manufacture its own mud agitator and export it to the world as needed.

Horizontal directional drilling operation often need the mud solid control system as operation service machinery and  the main reason of the system is for controlling the solid particles in the slurry produced by horizontal directional crossing drilling. GN Solids America LLC is the drilling machinery  manufacturer for horizontal directional, oil drilling and many type of well drilling operation.

Linear motion shale shaker is the 1st processing equipment of solid control system, it is used for separating the large drilling cuttings from drilling fluid, and it plays first filter role in protecting drilling fluid performance.

1. GN Solids America LLC use pair of the OLI brand motors from Italy which have the advantages of high strength vibration for produce motion for large screening area. The shale shaker have the adjustable screen box angle for a better mud flow and while shale shaker is in operation, it produce very little noise and high filter efficiency.
2. Heat treatment of the complete shaker deck. The surface painting with heavy anticorrosion formula paint to extend the service life of shale shaker.
3. Use the wedge secure format that secure steel or composite frame screen, the wedge can make to replace screen more convenient and easier and also can replaced into many kinds of screens.
4. Reasonable designing the feeding box height of shale shaker logging tank can make mud buffer is uniformity flow, reduce direct impact on screen and effective extend the screen service life.
5. We can manufacture custom made shale shaker in 316L stainless steel for clients’ anti corrosion requirements.

Our factory and company are Quality Management System ISO 9001-2000 certified and first Chinese solids control machinery manufacture certified by American Petroleum Institute.  GN Solids America LLC’s drilling Machinery is ideal vendor between quality, ETA and the price.

Drilling fluid containing ultrafine solids that size of 2 micron to 5 micron which has been separated by decanter centrifuge is sent to the storage tank to storage. For achieve the maintenance of the viscosity of the weighted drilling fluid is achieved by removing solids and colloidal particles that can cause high viscosity in the drilling fluid.  The barites discharged from the sediment export are sent back to drilling fluid circulating system for reuse.

The drilling fluid and barites can not be completely separated by using centrifuge during this process because that there are also large size of low density cuttings in the recovery of barites; Similarly,  the drilling fluid in the overflow contains both low density of fine solids and also very small and un-useful  barites particles.

There are use bentonites and finishing agent and also un-useful barites particles in the drilling fluid which is discharged and stored without being used. Therefore, we should add bentonites and treating agent to drilling fluid when adding the fresh liquid to the drilling fluid.

GNLW series decanter centrifuge line offer bowl size of 9 inches, 14 inches, 18 inches and 22 inches. It can meet the demand of different treating capacity.  Besides the bowl size, it also offers the various speed adjustment and fixed speed to meet the demand of mud treating for the drilling mud. The series number is GNLW363VFD, 453VFD, 553 VFD, 223, 363 and 452.  GN Solids America LLC has a large warehouse get to 30, 000 sq. feet. GN Solids America helps to keep many decanter centrifuges are available in Houston. GN Solids America is providing rental services for these centrifuges and the some other solids control and going waste management systems. We have full after-sale service tech on stand-by status to service our machinery in timely matter.

GN Solids Control is especially good at providing tailored solids control and waste management treating systems. Now GN Solids Control has provided equipment for customers from over seventy countries. Every year, over hundreds of customized solids and liquid separation equipment are provided.
Just take the oil slurry treating unit for an example, GN oil slurry treating equipment is mainly used to treat high density and high viscosity sludge like refinery plant oil sludge, oil tank sludge etc. Here is one inquiry we months ago for one Canada customer.
We as a company are in a process to submit an offer economic to the customer. Basically we have the need to manage waste generated in a heavy crude treatment plant, on the one hand we want to make the separation of solids in petrol sands approximately 660 Bls / D. We must also manage the production water and carry out the separation of the crude present in it, we should manage approximately 7200 Bls / D.
As mentioned previously, we are in the process of presenting an offer economic and I wanted to know the approximate cost of these equipment, and that can handle these proportions of waste.
I was reviewing the general brochure that you sent me and I thought of a system in series or parallel of equipment: Inclined Plate Clarifier and Oil Water Separator. I would like to know if it is possible to use it from this way, if you know of a project similar to the one I am mentioning, or if you can give me a better option for this.
According to the data that I was reviewing and the Data Sheet’s of the equipment I think it would be useful for me: Inclined Plate Clarifier 35 m3 / h and Oil Water Separator 98 m3 / h.

Based on customer’s above demands, we provided one set of oil sludge treating unit.

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.

Bowl Assembly:

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.
