Collision characteristics of particles in the friction device of triboelectrostatic separator
Abstract：For investigating particles collision characteristics in the friction device of triboelec-trostatic separator, the velocity and trajectories of two kinds of 10 ;m and 74 ;m spherical par-ticles were simulated in the two kinds of friction devices with different friction rods distribution using the standard k-e turbulence and particles trajectory model. The experimental study of temperature field distribution was completed inside the visual friction device model by an infrared thermal imaging technology. The results show that the temperature distribution is symmetric inside the friction device. The high efficiency collision of particles happened in the friction rods clearance with high temperature. The particles size and friction rods distribution has an obvious impact on the particles collisions. The collisions of equilateral triangle distribution friction device are better than that of foursquare distribution for the same size particles. The big size particles collisions are better than that of small size for the same friction device structure.
