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 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.
