Mud agitator can be classified to horizontal and vertical mud agitator. All GN mud agitators feature a brand motor coupled to a rugged oilfield gearbox, which eliminates misalignment and troublesome couplings. This configuration promotes longer motor and gearbox bearing life. This highly efficient gearbox offers a 95% power transfer, which is approximately 30% more than a worm drive gearbox.

Motors of Mud Agitator

The motors GN Solids Control used is brand motors in China, and as you requried, we choose different types of motors for the agitator. Continue reading →

Sand management is very important on oil and gas drilling, it effects the the drilling work, oil and gas production.
On the drilling work, the sand management is always referred as solids control system. Because the sand manage equipment is mainly a desander, and is a part of solids control, and if we want to have a excellent result, we must combine shale shaker, decanter centrifuge and so on.

Desanding the oil product is also important to make the oil clean. And thus desander is a very important part of it, and there are a lot sand control companies to do this.

There are two kinds of degasser in oil gas drilling solids control equipments, one is vacuum degasser i.e. centrifugal degasser, the other is mud gas separation i.e. poor boy degasser.

The centrifuge degasser works using the principal of centrifugal force to separate gas from drilling mud. The device passes a gas-cut material throough a centrifugal force field to accomplish the degassing. The degasser contemplates the slurry flowing through the degasser by entering it through the top and flowing downward or entering from the bottom and flowing upward. In either case the slurry moves through the force field to accelerate gravity settling of the continuous phase of the flowable material and to accelerate buoyant force gas bubble rising time.

ZCQ Degassers provide effective degassing with high throughput by means of a unique centrifugal Vacuum design.

ZCQ Degassers are capable of handling high viscosity 20 pound mud with a 50% gas cut. They can draw up to 800 gpm and discharge as much as 400 gpm.

The ZCQ Degassing system is totally selfcontained on one skid. No auxiliary pump is required. Both suction and discharge are powered by a built-in Electric motor. Continue reading →

Drilling mud & fluid conditioning systems is an important part of drilling work. And it always containing well control lines, solids control systems, fluids treatment equipments and fluids transfer equipment etc.. I list all of them below:

• Degassers and well control lines

• Solids control through shakers, centrifuges and desanders

• Fluid treatment with mixers, hoppers, mud labs and chemical storage and handling systems

• Compartment tanks of various sizes and designs for each use

• Fluid transfer equipment such as centrifugal pumps, agitators and mud pumps.

• Interconnect piping and hoses

• Electrical and instrumentation as required

• Ancillary items such as walkways, handrails, stairs, work and office spaces and any other items required

GN make vibrating screens for mining industry,and also design complete machinery for mining slurry separation,such as desanders, desilters,decanter centrifuges.We have exported vibrating screens and complete mineral industry slurry separation system to Turkey and many other countries around the world.

The vibrating screen is a kind of sieving equipment of international advanced level, developed by our company on the basis of carrying on the advantages of traditional screens and absorbing the outstanding technology from abroad

Vibrating Screen

It is widely used for grading and screening materials in the following fields: minerals, quarry, building materials, water conservancy and hydropower, transportation, chemical industry, smelting and so on.

Vibrating Screen Features:

1.Vibrating Screen uses eccentric block to produce strong exciting force.
2.Crossbeam and the main body of the screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance.
3.GN Vibrating Screen adopts tire clutch with capability of flexible connection and stable operation.
4.GN Vibrating Screen adopts the structure of small amplitude, high frequency, large obliquity to make the screen hold the capability of high efficiency, large handling capacity, long life span, low consumption, little noise. Continue reading →

Mud recycling system is important in hdd boring,  how mud travels in hdd no dig system, is always a problem people may ask. And then, we concern what GN Solids Control can supply, and who all over the world have chosen GN.

How mud travels in hdd no dig system

The mud is born clean, it was mixed by bentonite and some chemical mixtures, then stored by a tank. Ready to go to the hdd no dig system. Then it was pumped to the pipe and to boring the hole, later it was bring back by the pipe to a storage tank with all the cuttings rocks and sands.
The mud recycling is needed now, the drilling mud with sands and drilling cuttings are pumped to the system, then the cleaned mud return to the pipe.
The mud recycling is usually including shale shaker, mud cleaner, or desander and desilter instead, sometimes decanter centrifuge is also needed. The drilling mud flow through the shale shaker, desander cones, desilter cones, then the decanting centrifuge.

All units within the range use two processes when cleaning mud to ensure the drilling fluid can be recycled and used to the efficiency of the first time it is pumped down the hole.

The first process is with the use of a shaker screen. When the mud is drawn from the hole it is first discharged onto a fine mesh, which constantly moves from side to side spreading the mixture across it. This allow the drilling fluid to fall through whilst larger items such as rocks and cutting remain on the mesh until they are shaken off its bottom edge and removed from the system.
