Classification of decanting centrifuge

DCLW series decanting centrifuge is an
ideal equipment in drilling mud , It is widely
used in oil and gas drilling ,chemical ,foodstuff ,pharmacy ,mineral
benefication ,water treatment ,etc. Industries.

The decanting centrifuge have three types bellow:

A. low speed centrifuge:  Its
separation factor for 500 ~ 700, for low density solid phase, its separation
point for 6 ~ 10 μ m, for high density solid phase, the separation point for 4
~ 7 μ m, the centrifuge is used to recovery barite.

B. medium speed centrifuge: its separation factor for 800 or so,
separable 5 ~ 7 μ m of the solid phase is used to remove mud, the harmful solid
phase, control the mud weight and viscosity, this is the most widely used
drilling crew of centrifuge.

C. High speed centrifuge: its separation factor for 1200 ~ 2100 or so,
separation point 2 ~ 5 μ m, used to remove harmful solid phase, control mud
viscosity, general with low speed centrifuge used in series of double machine
system . In this system, the low speed centrifuge in the first, it separate
barite row back with mud tank barite recovery, it discharge of liquid first
into a buffer tank, then pump the buffer tank in the middle of the liquid into
high speed centrifuge, high-speed centrifuge separation out of solid discharge
tank outside, liquid back to the circulation system, the "two
machine" system can effectively remove harmful solid phase, and can
prevent a lot of waste of barite, widely used in china and foreign country. Our
company produces the LW series horizontal spiral sedimentation centrifuge
