| Summary: | This study proposes an analytical method considering the consolidation behaviour in centrifugal dewatering
of compressible filter cake. The main focus is on the consolidation behaviour after the disappearance
of the supernatant in centrifugal dewatering of thick suspension. Solving the consolidation equation
under the boundary condition proposed in this study, which represents the no flow rate due to the stable
meniscus at the cake surface, it is possible to describe the shrinkage of the cake after the disappearance of
the supernatant. Moreover, the analytical results show that, after the disappearance of supernatant, the
meniscus at the cake surface plays an important role on the drastic increase of the solid compressive
pressure near the surface and it has been clarified that the shrinkage of the cake mainly occurs near
the surface. |
