Abstract
Principles of determining the functional parameters and optimum sizes of a mixing chamber and its operating units were developed. Using the example of mixer operation at the vibration frequency f = 15 Hz and amplitude A = 0.006 m, the correction factors in the motion equation for dispersoids with open and closed valves were obtained. Graphs of the powder flow in the mixing chamber were plotted and analyzed. On this basis, the optimum sizes of the valve, which provide the assigned time mode of its opening, were found. The objective data of the mixer operation are given in the form of charge photography at × 200 magnification and diffractograms of mixture compositions for four samples.
