[Method and apparatus setup for preparing test dusts with a specified granulometric composition by air separation].
A method is developed and apparatuses constructed for the preparation of zeolite dusts for biological experiments in vivo and in vitro with dimensions under 5 micron. The method includes autogenic grinding of rocky zeolite material and air separation of the fraction under 63 micron, by means of cyclone and experimentally chosen conditions of work. The received "respirable" dust very well imitates the dust of the air from the working environment. The preparation of different experimental dusts is possible when suitable conditions, for working with the equipment, are chosen and the density of the material for separation is considered.
