Abstract

Method and its corresponding machine unit to classify by size a collection of particles separating them into groups with different particle sizes, using any method in which the collection passes freely through a space provided with obstacles, in which the distances between the obstacles - that is, the free openings between them - are more spacious than the largest particles that reach these openings, said method characterized in that a more or less similar obstacle space is added, in such a way that a stream of particles can pass without be disturbed from one space to another.
