MIXING TIME OF GRAIN MATERIALS .1. THEORETICAL CONSIDERATIONS

For the process of mixing any particulate system, the fundamental technological problem is the determination of the time necessary to obtain a mixture of the desired degree of mixing. In this paper, a method of determining this time, including the admitted estimation error, is presented. The method requires knowledge of the mixing-process kinetics based either on a theoretical model or on experimental data. It has been assumed that the particle distribution of the mixing tracer in each moment of the mixing process can be described by a beta distribution.
