A Method of Additive Aerodynamic Calculation of the Friction Gear Classification Block

Resumo

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.
