Loop-seal Operation of Iron Ore Particles in Pneumatic Conveying
Namkung W, Cho M
Loop-seal operation characteristics have been determined in pneumatic conveying (0.078 m ID×6.0 m high) with iron ore particles (680 μm and 4,500 kg/m(3)). Solids circulation rates through the loop-seal increase linearly with increasing vertical aeration rate at constant bottom aeration. When the aeration air is injected at the weir section and the lowest point of vertical section, stable higher solids circulation rates are obtained. The solids circulation rates are predicted by using pressure drop measured in fully developed region of riser. The calculated solids circulation rates are in good agreement with the measured values.
Keywords: Loop-Seal; Iron Ore Particles; Solid Circulation Rate
