FREE-FLOWING MATERIAL SUPPLYING AND DISTRIBUTING APPARATUS Russian patent published in 1997 - IPC

FIELD: agricultural engineering. SUBSTANCE: apparatus has contraction 3, funnel 5, diffuser 4, vertical pipeline 7 and distributing head 8 axially aligned one with respect to the other. Inner diameters of diffuser base part, vertical pipeline and distributing head are made equal. Ratio of inner diameters of truncated (small) diffuser and contraction is 1.2-1.6. Distance between contraction and diffuser is 0.1-0.5 of truncated inner diameter of diffuser. EFFECT: increased efficiency by improved uniform distribution of free-flowing materials with different physical and mechanical properties. 8 cl, 1 dwg
