MI-SWACO CD-250 centrifuge is designed for the purpose to solve a problem that there is no proper model centrifuge for small drilling process application with a compact dimension, for example, HDD, diamond core drilling for mining. It should meet 3 important points: 1 high separation efficiency, 2 tight space, 3 economic solution. GNLW220 centrifuge is designed for the similar purpose.

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:

centrifuge for mining diamond drilling

centrifuge for mining diamond 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
