The solid drum is internally
installed with a concentric discharge screw As they rotate in the
same rotation at a high speed, They have a certain rotational speed
difference, which is caused by the driving system and the
differential case Suspension enters the internal of the charge
screw through the speed pipe and then goes into the drum after
being accelerated Under the centrifugal force, solid particles of
big density settle on the in-wall of the drum, and form a circular
layer of cake, which is continuously pushed by the discharge screw
to the small end of the drum then out of it, while the settled
liquid is continuously discharge out of the drum from the vortex
finder of the big end of the drum, hence solid-liquid separation of
suspension.
