Operating Principles
Besides rotating, the 1st stage basket reciprocates axially,driven
hydraulically by a piston. In this way, the cake is pushed across the 1st
stage, onto the 2nd stage, and then exits through a static collection
channel and solids discharge casing.

Pre-thickening
Continuous operating
pusher centrifuges re-
quire continuous slurry
feed conditions.
Only with an optimum
pre-thickening of the
feed slurry it is possible
to achieved an optimumoperation of the pusher
centrifuge. Suitable pre-
thickening installations
and dosing devices can
help to fulfill these re-
quirements.
