RESEARCH OF THE SUSPENDED AND ROTATED LAYER OF PARTICLES IN CONTINUOUS AIR MIXERS

The article presents the results of experimental studies of the dynamics of the rotating layer in the mixing chamber of continuous pneumatic mixers. In the process of studying the rotating layer in the mixing chambers of aggregates, it was found that the distribution of the density of layers with particles for chambers with different lengths is a complex mathematical dependence on several factors: time t, the entry speed of the main flow into the mixing chamber v_(in.) and particle concentration in the volume of the mixing chamber. Based on the pairwise influence of pair factors on each other, the results of calculating the velocities in the mixing chamber at M_0=146 g and Q=168 m^3/h are presented. In connection with this study, the article provides a reasoned approach to a differentiated consideration of the mechanics of the rotating and suspended layers in the volume of the mixing chamber of an air mixer.
