Amethod of additive aerodynamic calculation of the process of aeration classification of particles of the components of materials as a function of their physical properties, unified by the integral criterion of “windage” and the parameters of a controlled directed air flow is proposed. Equations for determining the position of the receiving bin of the aeration classification block of a drum-shelf separator as a function of aerodynamic similitude criteria that assure maximal performance of the stratification of the original stock and, as a result, an increase in the quality of building materials, are obtained. The efficiency of aeration classification with the use of a controlled air flow is confirmed.
