GNLW series horizontal screw type decanter centrifuge is a leading design of function of decanting centrifuge.   GN Solids America LLC’s decanter centrifuge is the final process steps equipment in drilling mud cleaning system for solids control and drilling mud cleaning. The superiority function of decanting centrifuge is embodied in the solids size processing. GN Solids America LLC’s decanter centrifuge could remove the solid particles with size 2-7 microns using the principle of centrifugal force produced by the decanter centrifuge.

The choice of horizontal screw decanter centrifuge is important because it related to the whole mud cleaning work efficiency and operation cost of the drilling rig.  The facts need to be considering are list in below:

1 .The RPM of the decanter centrifuge for separation.   General horizontal screw decanter centrifuge can rotating RPM is 1800 to 4000 depends on the size of the Bowl. The higher the RPM speed, which leads to higher the separation of solids

2. Centrifuge parts materials: Different kind of material have its wear-resisting, corrosion resistance and other physicochemical indexes. GN Solids America LLC’s decanter centrifuge general minimum material is made of 316L of steel. The abrasive elements must use ceramic composites.
3. The controlling difference of the centrifuge: Difference in control effect accuracy of the differential, and the life and maintenance costs of decanter centrifuge. The higher the differential speed, the better the adaptability of the material, it is appropriate to use the device with high accuracy and high speed.
4. Diameter length ratio: the diameter/length ratio of horizontal screw centrifuge means the greater the processing capacity, the smaller the moisture content.
5. Control system: whether it is VFD programming control or fixed speed control, the decanter centrifuge manufacturers have basically produce the full VFD automation control of the machinery or fixed speed machinery.
6. Processing of the drilling mud: the horizontal screw decanter centrifuge is a high precision machining requirements of the solids separation equipment, not with the ability to produce high product maintenance, processing capacity is limited.

Hebei GN Solids Control Co., Ltd is leading manufacturer for drilling mud solids control & drilling waste management equipment and shale shaker screens.

Recently GN delivered a new designed solidification unit to our domestic client, it has been improved based on the previous design with the bigger storage capacity for solidification agent, flushing system, stronger mixing unit for heavy duty operation.

According to the feedback from the client’s rigsite, the storage capacity of chemicals is not big enough for drilling waste with more fluids, so the solidification agent storage box is bigger in the new design, so the new solidification unit could be used for multi drilling waste status- with more fluids content or with less.
Another change on the new solidification unit is the feeding hopper skid, the feeding hopper is much bigger than the previous stabilization unit, we consider the international container shipment cost, the auger could be disassembly during shipment and the whole solidification unit could be shipped by a 40 ft container.
Solidification unit is an economic way for drilling cuttings disposal when the fluids content is not too much, if the environmental laws is permit, but in some countries, solidification unit is not acceptable for environmental laws. Too much solidification agent cement and calc will be wasted and the cost will be higher compared with the performance.
Except for solidification unit, GN solids control also provided drilling waste management system, Thermal Desorption Unit, dewatering unit, vacuum unit, Screw conveyor, decanter centrifuge, vertical cuttings dryer, high G dryer shaker, Mono pump, etc. Solidification unit and dewatering unit, decanter centrifuge and high G dryer is normally used for water based drilling cuttings, vertical cuttings dryer system is normally used for oil based drilling cuttings.
We will keep improving our solidification unit according to the feedback of our clients, user friendly and the performance is our target to make our client satisfied.  For more information of drilling cuttings disposal, pls contact with GN solids control.

Unfortunately most of the HDD machines in India did not have a mud recycling system to reuse the drilling fluids, it is a huge loss of the HDD contractors that who never realized the importance of mud recycling system for HDD machines. You may own HDD rig made in USA, or you have HDD machines coming from China, whatever type machine you have, the mud recycling/ cleaning/mixing system can help you in the points below:

1) Reuse the drilling fluids or use the recycled mud to prepare for new mud, reduce the drilling cost
2) Lubricating the HDD rig
3) Cooling function
4) Reduce the drilling waste and only a small mud pit is required in the site, especially for some countries which have strict low for the drilling wells and drilling waste disposal, a mud recycling system can reduce the waste volume and make it easier to treat the waste properly.
5) Reduce the damage of the HDD machine and you can use it for longer time
At the beginning it is hard to convince the client who never used such mud recycling system for HDD projects to use it, he may ask why I should invest so much money for the mud recycling system. I can just leave it in the mud pit, it will be useless for me, etc. We have to show the client the successful case study of their competitors who began to use mud recycling system, they did job perfectly and fastly, the investment will be changed to profits in the future.
