Dewatering technology is greatly use for chemical separation of the solids phase form the liquid. By using some chemicals, the fine particles of solids flocculate into larger ones and to be separated out from the liquid phase. Take the oil and gas drilling mud industry as example, there are 2 main methods to be used, the dewatering centrifuge and the filter press. Seen from their outlook and working principle, they are quite different, but which to choose and why to choose is not only based on the first look, we need a detailed calculation.

  1. Purchasing cost. The cost for buying each of them is no much different, and also comparing with future consumption, this cost seems less important.
  2. The chemicals consumed: because of the high speed and high G force of the decanter centrifuge, no much chemical is needed. But in case of filter press, more chemicals in need for fulfil the work.
  3. Water usage amount: the decanter centrifuge need to be flushed only after continuous operating and the water consumption for each time is 3-4 cbm per day, but the filter press need to be flushed all over after usage, need around 150 cbm per day. In some water scarce place, this factor has to be taken into consideration.
  4. Human force needed: it is not a heavy work to operate or observe the operation of the decanter centrifuge, so one person for one centrifuge is enough. In case when several centrifuges are at same place, even one operator can work for them all. But in case of filter press, one filter press need at least 2 persons to run it.
  5. Spare parts: the spare parts for decanter centrifuge is less than the filter press.

GN centrifuges

GN Solids Control is professional in decanter centrifuges, GN has decanter centrifuges from 9 inch bowl diameter to 22 inch bowl diameter and now GN decanter centrifuges are not only used for oil and gas industry but also for other industries.

A .The adjustment of the drum speed.


The adjustment of the bowl speed is performed in  manual adjustment or decanter centrifuge plate prescribed maximum working speed following the adjustment.

Different rated speed by installed different size wheel by diameter for driving the main belt wheel to set different drum operation speed

In variable frequency drive decanter centrifuge will paired with control panel that allow increase and decrease the drum speed.

By fine-tuning the speed of the drum, it can perform more precise solids particles separation.  It can also improve the wear of the drum, the vibration and the noise to extend the service life of the decanter centrifuge.

The separation purpose or drilling fluid solids content  is by the choice drum speed. For instance, barite recovery or processing high-density mud, it is suggested that the low spending  speed. For general medium density mud prefer choose medium or high speed.  The low density mud is ideal for using high speed decanting centrifuge.

B. The adjustment of the differential drive


Centrifuge differential speed (back drive is also refer by) in its within the prescribed scope of, do not suggest user to adjust and it can only adjust in a small range change the parameters.

Different speed centrifuge adjustment methods are remove the original auxiliary motor pulley, and reloading large diameter or smaller diameter belt wheel  Auxiliary motor pulley  change the differential input shaft speed enhancement in result of differential speed decreased. On the other hand, it can also cause differential speed increase.


Operators must understand that regular maintenance on the centrifuge such as regular cleaning the inlet and outlet by filling water or diesel depends what kind of fluid it needs process.  It is also crucial that  add grease to the bearing parts to ensure proper lubrication.

Yesterday, GN’s manufacturing department done the fabrication of a mud mixing tank with increase hoppers. Mud mixing tank is widely used in the drilling mud system regarding mixing and re-configuration the actual drilling fluids. Also this will be used for storage the particular active drilling fluids.

mud mixing system
The mud mixing system is actually consisting of mixing tank, mud agitators, mud guns, mixing pump and mud hoppers. Usually, the mixing pump as well as the mud hopper will be situated at one end with the mud tank to make the mixing tank system a compact and also single unit, while in a few projects, the mixing pump and hopper are installed on another skid so that the mixing tank and the jet mud mixer could be used much unhampered. The picture in this article shows that the particular jet mud mixer skid was located at 1 side of the mixing mud tank. There are one mixing pump and 2 mud hoppers on the skid. The mixing pump is connected with the two hoppers, one of the hoppers is needed for mixing barite to create weighted drilling fluids, plus the other one is used for including bentonite into the drilling liquids.
There is a steel frame about second hopper with iron bars over the hopper. This specific horizontal steel bar is needed to hang the bentonite handbag which will be hooked at several corners of the steel structure to make it easier for adding typically the bentonite powder into the hopper. It is worthy to mention the fact that steel bar is with forklift lifting slot so that the club with bentonite bags may be lift and put on the shape by a forklift to save man power.
This mud mixing system is with a control panel to control mixing pump which could transfer mud to both hoppers. Around the mixing tank, there is one more charge pump which is used to help transfer the active mud back to the rig with regard to reuse.

The mud guns that place in the mud system’s function is to move drilling mud from tank space to another.  GN Solids America LLC’s mud gun can be either fixed or rotate setup for drilling operators to optimize the performance for the mud gun.

The mud gun can be use in high pressure and low pressure spray action by using different feeding pump.  The high pressure kind of mud gun is smaller design whole low pressure kind  is larger compare with high pressure kind .  The mud gun equip with movable nozzles and mounted on the mud tank with joint and connected with the pump.  It separate the drilling mud in jet form and mixing the drilling fluid in the pool of mud to keep the drilling mud consist mixed.

Mud Gun

The mud gun’s nozzle  is equip either fixed direction or rotated direction. The fixed nozzle is with hydraulic mixing line, the difference is that the drilling mud gun installed the two diagonal, nozzle direction parallel to the vertical tank wall tank. So as to form a can of drilling fluid layer rotation. But in the height direction, the jet effect can be ensured to ensure the convection of the drilling fluid.   The rotary nozzle drilling mud gun is by the input pipe, barrel, crosshead, two curved pipe with threaded joints, can change the nozzle and two coat nut composition, the gun body through the ball bearing and the input pipe is connected with. The drilling fluid through the inlet pipe, a nozzle, crosshead and start at a certain speed to the opposite direction. Speed depends on the drilling fluid pressure, density and viscosity.
