摘要： Layering of initially mixed granular dissimilar material components deposited by surface flow is realized by varying the relative angle of the flowing layer periodically with respect to the bulk of the pile formed. Layer thickness and extent can be controlled by varying the timing and extent of the surface variations. Variation in surface flow rates may be realized by varying the feed rate from an inlet to a collection base at a fixed feed location, varying the feed location relative to the collection base, tilting the collection base that is supporting the material, and reducing the pile repose angle using vibration or fluid flow through the base.
