Precise grading and sorting of sunflower plant materials in industrial facilities

The purpose of our research is to increase the efficiency mechanical and technological process sunflower seed mixture separation with vibro-pneumatic separators. This principle based on interaction flow surface having vibration-type vibration load by substantiating their rational regime-technological parameters. A system differential equations for motion seeds as granular gas under action a vibrating considered, considering elastic-damping physical properties seeds. solution basis mathematical apparatus numerical implemented in software package STAR-CCM +. To build models, are assumed have form ellipsoids certain density effective diameter. As result simulation moving material sieve, dependencies change total concentration – ? productivity q supply Q, sieve angle ?, oscillation frequency ? amplitude A. modelling surface, filling factor ?, distribution coefficient ? angles inclination ? ?, ?, given air rate V.
