According to the motor mounting type, there are 2 types of drilling mud agitators for mud system: Direct connection mud agitator and Coupling connection mud agitator.

Type 1: Direct connection mud agitator. The motor is mounted on a mounting plate with flange to gearbox reduce. It is the most popular type. The design is sample, but reliable. Most agitator supplier utilize direct motor connection design.

Type 2: Coupling connection mud agitator. The motor and connected to gearbox reduce via a coupling set. So the motor is not direct connected to the gearbox reducers.

The Coupling connection mud agitator has a coupling to protect the reducer and motor. In normal situation, clients only need to check and maintain the coupling set. However, there are additional wearing parts of the coupling. The disadvantage of the coupling agitator is that the coupling and its accessories need to be regularly checked on the drilling mud system. Once the coupling or accessories are damaged, they should be replaced in time, otherwise the motor and reducer will be damaged quickly.

The advantage of the direct agitator is that it is less maintenance as long as the gear oil is added. The disadvantage is that once damaged, either the reducer is damaged or the roller key of the motor shaft is damaged. It is difficult to repair. And the repair cost is high.

However, the probability of such a failure is very low and it belongs to an abnormal situation. According to the feedback records on the site, the damage probability of the agitator caused by not replacing the coupling parts in time is much higher than that of the direct connected agitator. Therefore, GN Solids Control recommended direct connect agitators. GN Solids Control standard agitator models are direct motor connection type. And most popular agitator brands provide direct connection agitator. They do not offer coupling connection agitators.

5.Chemical dosing dewatering unit. It is used together with decanter centrifuge for ultra fine solids separation.

The dewatering unit which is composed of high speed decanter centrifuge and chemical dosing unit are fixed inside a modified container. In this case, it is easy for movement and layout at jobsite. And the design is more compact for less footprint.

Mud tank is a basic device for drilling mud solids control system. Drilling mud tank looks sample. It seems easy for fabrication. The difficulties lie in design and pipelines to allocate all equipment. It is difficult to design the mud tanks to suit for clients demands on requested separation equipment and mixing system.

As every jobsite has different request for mud tank size, the number of mud tanks, mud tank usable capacity, the layout of mud tanks, and most clients have different request on separation equipment and mixing equipment, they request different models and numbers of shale shaker, desander, desilter, decanter centrifuge, jet mud mixer, pumps, etc… In this case, nearly every mud system is different. It is a big work to make the mud tank system designs and drawings, and need to change the designs and drawings again and again during the communication with clients. It is a huge work to make full package mud tank systems. It has high request on the manufacturers’ capability.

Shale shaker is a basic separation equipment. There are various types of shale shakers, like 3-panel shale shaker, 4-panel shale shaker, single deck shale shaker, double deck shale shaker, etc… Shale shaker is nearly used for all separation system. And it is the 1st stage solids control separation equipment in mud systems.

There is normally a sand trap under the shale shaker. The drilling fluid enters the drilling fluid mud tank system after passing through the shale shaker screen. The sand trap plays a very important role in the daily use of 80 mesh screen cloth or coarser screen cloth.

The bottom of the sand trap should be inclined by 45 ° to promote the sedimentation of large sand particles and rapid discharge outside the tank. The bottom inclined by 45 ° or more has a self-cleaning effect. The sand trap shall not be stirred, but shall enter the lower tank through overflow. Both linear and balanced elliptical motion drilling fluid shale shakers have this technology. Fine cobalt chips generally do not have enough residence time to precipitate. When cheap drilling fluid is used, the grit pump shall pump 1 ~ 2 times every 1H. At present, ultra-fine mesh screen cloth is widely used. Due to the expensive waste treatment cost and environmental concerns, such discharge is not allowed and the cost is limited.

After shale shaker, there are various types of separation equipment, clients can choose per jobsite demands and jobsite situation, like 3-in-1 mud cleaner, desander, desilter, vacuum degasser, middle speed decanter centrifuge, high speed decanter centrifuge, jet mud mixing unit, etc…

During the 1st snowing day of the winter, GN Solids Control workers keep working. The well packed equipment were dispatched from GN Solids Control factory batch by batch.

A full package of GNTBM-360 Slurry Separation Plant was shipped to the nearest seaport. Handling capacity of the system is up to 360m3/h.It will sail for a pipe jacking engineering company. GNTBM-360 is a compact design Slurry Separation Plant with small footprint. Although the design of GN seperation plant is very compact, there are 3-stage solids control separation equipment included in the unit. It can be used by tunnel boring machines(TBM), piling, pipe jacking, etc…

There is a coarse separation shale shaker equipment in the GNTBM-360 Slurry Separation Plant for the pre-separation. After that, recovered drilling mud will be fed to a double deck mud cleaner for bottom deck shaker separation. And then drilling mud can be pumped to desander cyclone and desilter cyclones for the 2nd stage and the 3rd stage separation.

Heavy duty slurry pumps are used in GN slurry separation plant to feed dirty mud to shale shakers. And than centrifugal pump, also called as sand pumps are used for desander and desilter feeding. In case of decanter centrifuge is applied for fine solids separation, submersible slurry pump or screw pump can be used for mud feeding.

The GN Solids Control Slurry separation unit is popular for project of AVN Machines , Mix shields  or Shaft Sinking Machines. GN Solids Control utilize shale shakers, desander, desilter, as well as decanter centrifuges to process liquid and solids separate, and remove the excavated solids from the bentonite suspension – a mixture of water and thixotropic clay. The cleaned fluid is then transferred back to the slurry circulation.
