Engineering Properties of Finger Millet (Eleusine coracana L.) Grains

Some physical properties of finger millet (Eleusine coracana) grains were determined at the moisture content of 13.43 per cent (w.b.). The size, sphericity, surface area, geometric mean diameter, test weight of grains, true density, bulk density and porosity were 1.672 mm, 0.95, 8.02 mm2 , 1.60 mm, 2.91 g, 1.1561 g/ml , 0.8604 g/ml , and 25.49 %, respectively. The frictional properties of the finger millet grains viz., angle of repose, coefficient of static friction using different surfaces were also determined and the values were 25.25o, 0.413(mild steel), 0.3713 (galvanized iron), 0.2899 (stainless steel) and 0.241(Perspex), respectively. The terminal velocity of the grains was 2.94 m/s.
