Mathematical description of the carry-over of the ground material intothe separation spaceof roller mills

Abstract

Developed a mathematical description of the ash particulate material in the separation space roller mills. A mathematical model of the motion of particles in a swirling upward gas flow, for the first time takes into account the concentration of the solid phase. The dependence of the axial velocity of the particle on the velocity of the carrier medium at different concentrations of the solid phase. It is shown that at low solids content (1–5%) relative to the carrier gas environment with unrestricted conditions, the influenceof neighboring particles on the trajectory can be neglected.
