EFFECT OF STRUCTURAL PARAMETERS OF CASCADE ELEMENTS ON EFFECTIVENESS OF PNEUMATIC CLASSIFICATION

摘要

Experimental data on the effect of basic structural parameters of contact elements on the effectiveness of pneumatic classification of granular materials are analyzed. Optimal values are ascertained for the "free cross-sectional area " of the contact elements, their length, angle of incline, positioning in the separation channel of the pneumatic classifier, and the distance between them. The data obtained were used in developing a procedure for analysis of the structural parameters of cascade pneumatic classifiers.
