Abstract:When pressure filtration is used to produce composite materials from a mixed suspension, segregation of the different particle types is apt to occur due to different sedimentation velocities. This results in an inhomogeneous, thus inferior product. To understand and reduce segregation, a model is proposed to describe segregation due to gravitational settling during pressure filtration from a dispersed suspension consisting of two types of particles with different sizes and/or densities. The model combines the consolidation mechanisms of sedimentation and filtration and predicts the composition profile in the formed material. Experimentally determined cast profiles are in good agreement with model predictions.
