The mud cleaning system produced by GN solids control is widely used for horizontal directional drilling , water welling drilling ,coal bed methane, geothermal hole and mining diamond core drilling , it is used to separate the drill cuttings from the mud, so that the clean mud can be re-circulated to continue the drilling process.

As the Geothermal drilling usually close or inside the downtown, this requires the mud system to be compact with less footprint and user friendly with less noisy. Also Geothermal well drilling sometimes require high capacity performance for deep wells. Below is the jobsite photo of mud cleaning system for geothermal drilling, which is produced and commissioning by GN solids control.

Like water well drilling, mud rotary drilling is also the desired method for installing geothermal loops. As the bit penetrates the soil, it creates smaller fragmented pieces that are called drill cuttings. The mud carries these cuttings to surface to create an open hole from the top down to the bottom. The drill cuttings are collected into a mud pan or settling pit on surface and then the mud is re-circulated to continue the drilling process.

The mining sector in Chile is one of the pillars of Chilean economy and copper exports alone stands for more than one third of government income. Mining Minerals exploration by diamond core drilling will need decanter centrifuge. Usually the decanter centrifuge for mining is different with oil & gas drilling. The latter one will be with small handling rate and high G force, it needs to separate fine microns. The decanter centrifuge used for oil drilling fluids usually with larger treating capacity( 40~60m3/h, like MI-Swaco 414, 518 series or GNLW363 &GNLW364G decanter centrifuge).

Features of decanter centrifuge for mining diamond core drilling:

1 Small handling rate:

GNLW220X660 centrifuge with treating capacity 150L/MIN, centrifuge bowl 9”, bowl length 26”.

2 Small foot print

Diamond core drilling mud system should be portable system with small foot print and easy to move from one site to another, so the centrifuge applied should be also small foot print. GNLW220X660 centrifuge dimension is 865×1080×755mm and weighted 750kgs. It is an ideal model for mining drilling mud system.

3 High rotary speed, high G-force( separation sector)

GNLW220X660 centrifuge with rotary speed max to 4000rpm, the operation speed is 3500rpm. The separation factor in 3500rpm can reach 1500G, it can separate fine particles to meet diamond drilling requirement.

Other advantages of GNLW220X660 centrifuge:

4 large extruder L/D=3, high speed, small speed differential gear, large torque
