    The results of experimental investigation of the continuous sedimentation of dilute model of fine-grained suspension in the intermediate region of settlement are analyzed. The effect of the particle size (glass beads of average diameter 150-850μm, concentration and inclination of the vessel axis on particle fall velocity is evaluated. It is confirmed that the local relative particle-liquid velocity has a practically constant value across the vessel cross-section. The settling pattern is strongly affected even by a very gentle slope of the vessel axis, which causes an asymmetrical absolute velocity profile and significant increase of the local concentration and absolute fall velocity of particles near the upward-facing wall of the vessel.
