Classification of decanting centrifuge

2012-12-17

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 applicable scope see table below:
