The only limiter is used between the first hole and passage to maintain or intensity swirling effect. Powder-like substance located inside chamber is caught by swirled air inside chamber and is divided into small particles uniformly due to air swirling effect which may be intensified by introduction of moving element, such as a ball, into chamber and/or by installation of central core inside chamber.
