In some mining projects, before the exploitation, the contractor would like to do some research on the geological condition. The most popular method is to use the core drilling machine to get some sample of the stratum. By analyzing the stratum sample, the mining operator would get some basic information like the mineral reserves and what kind of the mineral it is.

When getting the sample of the stratum, the contractors always apply to use the core drilling machine to get a series column shape stratum. The drilling bit is a type of pipe, not like the drilling project for oil and gas, the core drilling not need too much drilling fluids to cool down the drill pit and take the cuttings out from the drilling whole. However, in order to make sure the better performance of the drilling process, the drilling contractor always will get a solids removal unit to separate the drilling cuttings from the drilling fluids.

Now the solids removal package unit specially for core drilling designed and manufactured by GN Solids Control has already been applied on site and the performance was proved good.

GNLW223 Centrifuge

GN Centrifuge for Core Drilling

In GN’s solids removal package unit, the equipment involved is as below:

Shale shaker model of GNZS752 with 2 panel screens, which is used as the first stage solids removing unit to separate out the larger size solids in the drilling mud.

High speed decanter centrifuge GNLW223 which is also the key equipment in this solids removal unit. It could run at a typical speed of 3800 RMP that ensure a good performance for dewatering. The semi-dry solids discharged out from the centrifuge unit could be transported easily.

Considering the requirement of the small footprint, this solids removing unit is designed structure compact and the mud tank only has 2 compartments separately to be used for sand settling and mud mixing. The centrifuge pump used in this system could both transfer the mud to centrifuge and mud mixing. This dual function centrifugal pump saves great power cost and reduces the system size.

For the power supply, GN could also provide a diesel generator as an option.

GN Solids Control is welcoming the customer worldwide come to us for learn more about the core drilling solids removal unit.

GNLW223 Series decanter centrifuge is a main product of GN Solids Control, different from the centrifuge used in oil drilling and drilling cuttings management system. The GNLW223 centrifuge is more compact structure and has a relative small treating capacity which determines this series decanter centrifuge is always be used in diamond drilling mud recycling.

GNLW223 Decanter Centrifuge

GNLW223 Diamond Drilling Decanter Centrifuge

GN now could provide this GNLW223 centrifuge electric drive fixed speed GNLW223G and Variable Speed GNLW223-VFD.
Both of the two models are driven by one unit electric motor. Regarding the motor and control panel, GN could also provide IEC explosion proof standard which could be used in hazardous area. Some customer may prefer the fully hydraulic drive model, at this time, GN hydraulic driven centrifuge for GNLW223 still under research process. But GN could provide the Decanter Centrifuge without motor and control panel, the customer could get the hydraulic driven unit locally and assembly together with the mechanical part. The unit which was sent to Canada is like that.
GNLW223 series decanter centrifuge has a normal treating capacity of 6 cubic meters per hour. The designed maximum rotating speed is 4900RPM. If variable frequency drive, the speed would be 0~3800RPM. Under general condition, the solid particles size in diamond drilling is very fine, however, sometimes, there would be large size drilling cuttings. Thus, one unit shale shaker maybe needed as first stage cleaning equipment to remove the large size solid particles. GN has a mini model shale shaker GNZS752 is especially for this job.
The mud system for diamond drilling is very simple; always it is consisting of mini shale shaker, GNLW223 decanter centrifuge, and mud tank and mud agitators.
Diamond drilling is very popular in Canada, there are more than 50 diamond drilling company in Canada right now. GNLW223 series decanter centrifuge has already been used in Canada for diamond drilling and performance proved very good.

Shale shaker is the act as the first stage solids control equipment. Its performance important to the whole system. If the shale shaker can work well, it can greatly improve the lifetime of next stage equipment.

Shale shaker vibration

Vibration of the shaker basket creates G-forces which help drive shear thinning fluids such as drilling mud through the screens. Vibration also conveys solids off the screens. Most linear motion shakers operate in the range of 3 to 4 G’s to balance throughput with screen life. G-force is a function of vibration frequency (rpm) and stroke length.

Top brand Linear motion shale shaker

Top brand Linear motion shale shaker

But there are alway some misunderstanding on shale shaker performance, it should be avoided :

• “High-Speed” should not be equated with “high performance”.

Laboratory tests indicate that, in the normal operating range for linear motion shale shakers, lower frequency vibration and longer stroke lengths improve throughput capacity. Most linear motion shakers operate at 1200 to 1800 rpm.

• Avoid deck inclinations above 3˚.

High deck angles reduce solids conveyance and increase the risk of grinding soft or friable solids through the screens.

• Shakers are designed to accept either hookstrip or rigid frame screen panels.

Hookstrip screen panels are the most common and are usually cheaper, although cuttings wetness can be a concern due to deck curvature. Flat, rigid frame panels promote even fluid coverage, but can cost more.

• Shakers may have single or tandem screening decks. Single deck shakers offer mechanical simplicity and full access to the screening surface. Single deck shakers may be arranged to process mud sequentially as a “cascading” system to improve performance under high solids loading conditions. Tandem deck shakers offer improved processing capacity under high solids loading conditions when space is limited.
