Abstract
In the pneumatic transportation, it was proposed by the authors that the effective and stable feeding of the particles can be attained by mounting the injection flow at the center of the suction nozzle. In this paper, the experiment was made on the influence of the nozzle height from the particles bed surface. It was found that the loading ratio increases except for the range of excessive injection flow as the nozzle height decreases. The factor of those phenomena was clarified by the flow visualization.
