In this report, the mixing mechanism of a binary system of particles with different electric resistance, group A and group B, was treated by use of a two-dimensioanl model. Before mixing, the particles of group A and group B, were arranged in a parallel circuit, as shown in Fig. 1, (c). Accompanied with the beginning of rotation of impellar blades at angular velocity ω_<1-3>, the particles belonging to 1, 2, 3 orbits began to move in their orbits at the same velocity as that of impellar blades, while the particles belonging to 4, 5 orbits had less velocities (ω_4, ω_5) than ω_<1-3>. Together with the rotational motion of particles, the random exchange of positions of particles occurred. Thus, the resulting equation was as follows. R=l×e^<kt>×∣Σa_i ×sin(ω_i×t)∣+(m-n×e^<-kt>) where, R: Total electric resistance a_i, k, l, m. n: Constant ω_i: Angular velocity t: Time
