内容記述(抄録等)This report concerns so called 'high density, low velocity' pneumatic conveying method of granular materials. This method of transport of granules has two big profits. Namely, i) it is suitable for the transport of fragile granules and ii) it causes smaller abrasion inside surface of the duct owing to the low velocity of granules. To avoid the breakage of fragile granules we prepaired test equipment in which the granules are conveyed as clusters (a train of slugs) with very slow velocity (about 1m/s). This time, we made a test of transport with the horizontal square duct (cross section; 6.6×6.6cm, length; 4.5m) and measured the pressure drop across the slug, velocity distribution in the slug, and the transported rate of granules. Results obtained are as follows; 1. In this experiment, the pressure drop ⊿p across the slug was largest in the beginning of transport. For rape-seed ⊿p was 560mm Aq, for nylon chip ⊿p=473mm Aq, and for N.P.K. (a kind of granular fertilizer) ⊿p=490mm Aq. 2. Average transport verocity of the slug υ was 1.2m/s for rape-seed, 1.19m/s for N.P.K., and for nylon chip υ was 1.06m/s. 3. Flowing pattern inside the slug became clear for the case of rape-seed.
