Diamond Drilling

500GPM and 1000GPM are the most popular size drilling rig mud recycling system for Horizontal directional drilling, water well drilling, Coal bed methane drilling, and other trenchless drilling rigs.
500GPM mud recycling system is mostly a compact 1-tank system complete with separation equipment and mixing unit for compact design and easy movement.

Regarding 1000GPM mud system system, clients can choose 1-tank system or 2-tank system. 3-shaker mud recycling system and 4-shaker mud recycling system are the most popular proposal. 3-shake mud recycling system means 2 shale shakers plus a mud cleaner (3-1 mud cleaner, desander mud cleaner, or desilter mud cleaner).

Equipment list for 1000GPM mud system is normally as below:

1) At least 2 sets shale shaker. 4-panel or 3-panel shale shaker model are both fine. Single shale shaker model is min. 500GPM capacity. So for 2 shale shakers the handling capacity can reach to 1000GPM minimize.

2) 1 set of mud cleaner c/w shale shaker, desander and desilter, mud capacity is at least 1000GPM. It is the full functional and with compact design. As a 3-1 mud cleaner can save footprint. If clients want to reach a better separation performance, they can also choose a separate desander mud cleaner, or a desilter mud cleaner. Regarding the desander mud cleaner and desilter mud cleaner, clients can choose to equip with the same under flow shale shaker as the first stage shale shaker, or a mini size shale shaker with 2 screen panels. Clients can also choose a small desander or desander without shale shaker.

3) Feeding centrifugal pump for mud cleaner is 45kw or 55kw. The feeding pump can be located on tank skid or tank slope.

4) Mixing unit is C/W 6 inch mixing hopper. Mixing pump can be 45kw or 55kw. It is better to be the same model with mud cleaner feeding pump.

For 3-shaker system, all separation equipment and the mixing unit can be located on the same mud tank for company design. But if it is 4-shaker mud system, the first tank is recycling tank with separation equipment, the next tank is mixing tank.

GN Solids Control makes Mud Recycling System and desanding plants for construction Trenchless Engineering Companies, like for HDD (horizontal directional drilling), TBM (Tunnel Boring Machine), Microtunnelling, piling, etc…

GN Solids Control has more than 10 years of experience in the design and manufacture of mud recovery systems, especially in trenchless projects with multi-function and compact design to cater for different demands and applications from clients. According to the different requirements from users, and jobsite situations, GN Solid Control can provides different configurations of mud recovery system and desanding plant to meet the requirements of different working conditions. There are usually two types of mud purification systems suitable for trenchless construction: one is sand removal unit with cyclone purification system, we usually call it desanding plant. And the other type of design is self-contained mud recovery system.

The desanding plant with hydro cyclone purification system occupies a small footprint, and is economical and affordable. The system is composed of a hydrocyclone and a double deck shale shaker, both of which are installed on a small mud tank. The sand removal cyclone purification system is a two-stage separation device, and its function is to remove coarse particles from drilling mud. The desanding plant is mainly used in projects that can accept larger particle size solid drilling mud, such as Microtunnelling, piling, and so on.

The high standard self-contained mud recovery system developed by GN Solid Control is composed of four stage separations: shale shaker for coarse cuttings separation, 10 inch desander cone separation, 4 inch desilter cone separation, and decanter centrifuge for ultra-fine solid separation. The mud tank of the self-contained mud recovery system has a bigger storage volume to store the purified drilling mud. At the same time, it also has more tank surface space to arrange more separation equipment. Customer can also choose a centrifuge to reduce the ultra-fine solid in the drilling mud and to avoid the enrichment of the ultra-fine solid phase in the drilling mud.

GN Solid Control not only has a standard sizes of mud recycling system and desanding plant, but also provides custom-designed mud recovery system to meet for different demands.

In the just past MinExpo 2016 exhibition for especially for mining industry, GN showed the 9 inch decanter centrifuge there and many visitors came to GN booth showing great interesting to this unit.
9 inch is the smallest size model in GN’s decanter centrifuge production line. GNLW223 is the typical model number of this size, now both the fixed speed and VFD model available. At this time, all GN’s decanter centrifuge is electric driven; however, GN is researching the FHD model that is more preferred as less energy consumption.

GNLW223 Decanter Centrifuge – 9 inch

GN 9 inch decanter centrifuge unit can run normally at 3800 RPM for long time working condition, while the designed maximum RPM is 5000. GN’s dynamical balance testing instrument can test the decanter centrifuge at actual working speed, even the maximum designed RPM. This ensures the stable working performance.
GNLW223 series decanter centrifuge is mainly used for small capacity solids removal project. Diamond core drilling is a typical industry that will use this type decanter centrifuge. With a high working speed, the centrifuge unit would remove the ultra fine solids like less than 5 microns from the drilling fluids. Ceramic tiles are inlayed for protection of the screw propeller, which extends the working lifetime. For the customer who prefers the FHD model, GN also provides only the mechanical part like bowl assembly and bearing seat, customer could equip the hydraulic driving system and electric control system locally.
Some mining operators would ask put a shaker unit before the decanter centrifuge, thus the coarse solids could be removed firstly. Then the slurry with fine solids will be fed into the centrifuge. The function of the shaker is to remove most of the large size solids, which will greatly reduce the working load of the centrifuge. It is also a protection on the centrifuge unit.
Now GN already developed the compact solids removal unit including mini shaker and 9 inch decanter centrifuge. This system also has mixing system for adding bentonite into the fluids. Its compact structure make it could be helicoptered to lift to a remote area for working.

Diamond core drilling is a type of drilling used to get the stratum samples so that the geological experts could analyze what under the ground, and if there is mineral reserve, how deep need to be drilled for exploitation. Diamond core drilling always uses tube type drill bit for getting a cylinder earth sample. The drill hole is not too big to use plenty drilling mud. However, on consideration of environmental protection, the recycling of the
drilling mud is firmly requested, which is also a method of cost saving.
