LW Decanter Centrifuge

LW Sedimentation Centrifuge is a horizontal,continuously working and continuously spiral discharging sedimentation centrifuge. 

It is used in a variety or industries for separating all kinds of solid liquid suspension.

product description

LW Decanter Centrifuge

Working Principle

The machine starts and speeds up automatically.

When the proper working condition are met and the revolving drum reaches the feeding speed,

the feeding valve opens and allows suspension which will be separated to enter into the product compartment of the spiral feeder through the feeding pipe.

After the preliminary speed-up,the suspension passes the outlet of compartment and into the drum.Because of centrifugal force,

the suspension in the drum is quickly divided into two phases;

the heavier solid phase deposits to the inner wall of the drum and driven by the differential gear which results in the non-cynchronous movement between the spiral feeder and the drum.

the solid phase will be transferred into the small end for further dehydration and finally discharged through solid phase outlet.

The separated liquid flows out though the big end or will be driven out by centrifugal pump.
