โฆ Synopsis
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 particles generated during their pneumatic transport.
