Abstract
The invention relates to obtaining flow of electrically charged particles of a substance (such as dust). The invention is directed to attaining a technical effect of simplifying design and providing possibility of obtaining flow of charged particles with no use of high voltage sources. The technical effect is attained by a source of charged particles implemented as an inner hollow cylinder and an outer hollow cylinder with a gap between them, with a means for providing airflow with substance particles along surfaces of the cylinders that form the gap. The airflow is directed from first butt ends of the cylinders to second butt ends of the cylinders. Materials of the cylinder surfaces forming the gap are selected so that the substance particles and the surfaces obtain opposite electrical charges upon friction of the substance particles against the surfaces.
