Outline of Final Research Achievements	Efficiency of soil washing due to lamellar inclined channel and static mixer is studied experimentally. The soil washing instrument is composed of two zones, i.e., agitation and classification zones. Swirlers and a static mixer are set in the agitation zone, and laminated plates are put in the classification zone. The performance of the lamellar channel is the highest at the inclination angle with 60 degrees from the horizontal line. We found that the static mixer could classify soil by trapping heavy soils in their wakes in the mixer.
