GN decanter centrifuge can be used for drilling mud treatment, waste water treatment, to remove fine solids from liquid medium, thus to adjust the physical property of the liquid medium, eg. Viscosity, density, weight etc. GN can offer high speed & middle speed centrifuges, treating volume is also different from small capacity to big capacity. GNLW 223 is GN mini centrifuge, small capacity, high speed, which can be used for waste water treat for diamond drilling. The speed can reach to 3800RPM and treating volume is about 6m3/h. Price of GNLW223 is also fit for diamond drilling fields. GNLW553 is GN big bowl big volume decanter centrifuge. The volume can be 500gpm and the speed is adjusted from 1800RPM to 2500RPM. The big bowl centrifuge is specialized for fast drilling, or other type of application. GNLW363 is GN most popular model centrifuge. We have over 150sets centrifuge for annual sales amount. The centrifuge is widely used in solids control, waste management, waste water, environmental projects and so on. For this model, we can offer 4 types centrifuge: GNLW363CD fixed speed centrifuge, economic configuration GNLW363CD-VFD variable speed centrifuge, economic configuration GNLW363CG fixed speed centrifuge, premium configuration GNLW363CG-VFD variable speed centrifuge, premium configuration 
Regarding the fixed speed centrifuge, we can offer 2200RPM, 2700RPM, 3200RPM bowl speed by changing the pulley with belts; variable speed centrifuge, it can be adjusted stepless from 0-3200RPM. Regarding the production material, GN premium centrifuge is better than economic centrifuge, with better working performance and long lifetime. Except for drilling mud decanter centrifuge, GN can also offer complete line of solids control equipment, including shale shaker, mud cleaner, centrifugal pumps, shear pumps, screw pumps, mud agitators, jet mud mixers, mud gun, mud tanks. GN can also offer complete line of drilling waste management equipment, including High G dryers, vertical cuttings dryer, waste management centrifuge, cuttings solidification unit, thermal desorption unit etc.
