A method of mixing Particulate materials during their pneumatic transport is proposed. The calculation of this operation is hased on the efGctive Particle dispersion coefficient determined in extxriments. This new method of Particle mixing has heen used to neutralize the electric charge on the parti

β¦ Synopsis
The theoretical concepts of complete and incomplete mixii have been dheumed and a deilnition for complete mixing has been proposed, using a statistical hypothesis as the tesi criterion. The application of this has been coniirmed experimentally and it has been shown that, with random sampling, n, the number of particles in a sample, and 8, the proportion of particles of type A in the sample, follow normal distributions.
It has further been shown that a small number of samples examined statistically, is suillcient to indicate whether or not mixing is complete at any time during the mixing process, and that the progress of mixing with time may be followed statistically.

The shortest distance test described in a previous publication has been applied to evaluate the randomness of solid-solid mixtures. Mixtures for evaluation were prepared by combining sieved coloured and white fractions of ceramic powders, The possibility of obtaining complete randomness was investig
