The augers are also called the screw conveyors, they are used in GN drilling cuttings waste management system as a matching equipment alongside with vertical cuttings dryers and decanter centrifuges.
In some rig sites, it is requested by the law that for each drilling rig, there must be a set of drilling cuttings waste management system, and totally in the rig site, there should be at least 2 augers: first one is below the discharge chutes of shale shakers, desander cones and desilter cones, that is used to collect the cuttings. Second one is used as a sloping angle to transfer the cuttings from the first one to the vertical cuttings dryer. In a word, the augers could be positioned sloping or horizontal for different destinations. In a word, GNSC screw conveyors could work in a group or singly, and they could be used for mixing, allocating, dewatering, discharging and etc.

As an essential part of a waste management system, in order to well match the other equipment and easy for transportation and locating, all GN screw conveyor models are designed in same length sections, each of 12 ft. And they are of different diameters for providing different transferring capacities. There are 10 inch diameters, 12 inch diameters, 14 inch diameters and 16 inch diameters. In this condition, most of spare parts are interchangeable, which reduced the spare parts cost and enhanced the convenience for the end users. GNSC series screw conveyors are using the wear proof material for a obviously longer service life than its peers’.
GNSC series screw conveyors are not only used in the drilling cuttings waste management systems, they are also quite widely used in construction, chemical, power plants, coal mining and other industries. In some customized conditions, GN could also add the insolation layer to the augers to keep the temperature at a certain range.

After being developed from a solids control manufacturer and focusing on only high quality product manufacturing, GN Solids Control has become more like a separation professional and their salesroom is more and more occupied by some more widely used separation equipment which are suitable for more industries covering the oil and gas solids control, waste management, oily sludge separation, mining, TBM, HDD, food industry and also waste water separation.
Decanter centrifuge is quite an important equipment for the separation work. For example, a middle speed centrifuge could separate out particles from 5 to 8 microns like the expensive barite in the drilling mud, while a high speed decanter centrifuge could separate out the cuttings from 2 to 5 microns. With help of a chemical dosing system, the even smaller particles could be separated out together with a flocculation unit.

GN Hydraulic centrifuge

GN Hydraulic centrifuge

Comparing with other separation equipment, a centrifuge has many advantages like continuous operation, easy for maintenance and requesting less chemical components to be invited. GN has a full range of decanter centrifuges with different sizes, including 9 inch diameter bowl, with length-diameter ratio of 3 and 4 ( long or longer), 14 inch diameter bowl, 18 inch diameter bowl and 22 inch ones, they all have models of 3 or 4 as length-diameter ratios. And GN also has 30 inch diameter bowl decanter centrifuge, with a bowl length- diameter up to 4.
Among all those models, the 14 inch bowl models are most popular and economic, which are suitable for many applications. And for this model, GN has also hydraulic control model for option. Recently, one set of hydraulic decanter centrifuge will be shipped to an oversea customer, and it will be used for a big oil drilling company. Meanwhile, some more decanter centrifuges are being built for a safe stock and delivery to clients.

3. Matching shaker quantity: 2 or 3 sets
4. Suitable mud: all types of mud including SBM, OBM and WBM
5. Mud recycling ratio: 30 to 50 percentage
6. Mud temperature from minus 15 degrees to 85 degrees centigrade
7. Control type: automatic pneumatic control
8. No electrical power needed

Features and advantages of GN ViST Vacuum Shaker:
1. Wide application for all mud type including WBM, OBM and SBM.
2. It is suitable for both land rigs and offshore rigs, to enhance the working efficiency of the shake shakers, to recycle the drilling fluid to the most while discharge the cuttings to the least.
3. A ViST shaker could replace the drying shaker at a lower cost comparing with drying shaker.
4. Small footprint, even no extra space needed when added onto existing shakers, which is very important for offshore conditions.
5. Easy for installation for both GN’s own shakers and other brands’ shakers.
6. By using a ViST devise, the solids control shale shaker can use shaker screens with larger API number without leaking, in order to enhance the treating efficiency.
7. By discharging dryer cuttings, it would be easier for transport or discharge the drilling cuttings.
8. Easy to be operated by one operator only.

gn mud system

1. GNZS703F-DZ shale shaker. This is the best seller shaker model among GN shale shakers especially for the non oil gas industry. In this shaker design, GN has 5 patents like the unique sealing design, the gear unit for changing the screens and etc. The G force of this shaker model is upto 7.5G, adjustable. And shaker deck angle could be adjusted from minus 2 degree to plus 5 degree for a good performance. The shaker deck is made of stainless steel, for a stronger structure. It has 3 pieces of composite material frame screens, which gives 2.63 square meter screen area.
For the same model, GN has also high-G drying shaker available, with G force up to 8.5G.
2. GNZJ703F series desander and desilters. In this system, because of enough space and enough budget, the end user chose the desander and desilter design alongside the shale shakers. The desander has 2 of 10 inch cones and an underflow shaker, while the desilter has 12 of 4 inch cones with underflow shaker. Both of the underflow shakers are same as GNZS703, with interchangeable shaker screens, of course, different API numbers.
3. Mixing unit is equipped for this mud system, too. Both the mud mixing hopper and mud mixing pump are fabricated by GN Solids Control.
4. GNSB series centrifugal pumps are also one of the core products GN produces and provides. All GN centrifugal pumps, including individual parts are fully interchangeable with Mission Magnum centrifugal pump. They are widely used for the desander or desilter cone feeding, for the mixing purpose, or serve as charging pumps and transfer pumps in trip tanks.

2. GN shear pump. Shear pump is not so commonly used as centrifugal pump. They are only used for shearing some special chemicals which are needed for large horsepower oil and gas drilling rigs.
3. Submersible Slurry pump. Submersible slurry pump’s applications in GN solids’ mud system and mud units are mainly those two: one is for centrifuge feeding in solids control systems like for the barite recovery and extra fine particle separation, or for the HDD mud recycling units, it is the second to none choice for transfer slurry from the mud pit to the mud system.
4. Vacuum pump. GN series vacuum pumps are the newest member among GN pumps. But it gained highest attention ever since its birth. Comparing with other pumps, the most obvious difference is that it has no motor. It is fully air driven and has less limitation for the solids size. In practice, it could handle material with particle size only a bit smaller than it’s pipeline diameter.
