Air filling - Kuukijuten

Japanese: 空気充てん - くうきじゅうてん
Air filling - Kuukijuten

…Iron pipes are used for filling pipes, but since bent parts are particularly prone to wear, chromium steel or manganese steel is used in those parts, and sometimes a wear-resistant lining is also used. Air filling is a method of transporting the filling material by air flowing through the pipe, and the particle size and transported amount vary depending on the flow speed and flow rate. Compressed air of 1 to 4 atm is discharged to generate the air flow, and the pipe diameter is 150 to 200 mm, the filling capacity is 20 to 80 m3/h, the air consumption is 80 to 200 m3 of free air per 1 m3 of material, and the transport distance is usually 200 to 800 m. …

…充てん管には鉄管が用いられるが,屈曲部はとくに摩耗が激しいので,その部分にはクロム鋼やマンガン鋼が用いられ,さらに耐摩耗性の内張りをすることがある。空気充てんは,管内を流れる気流によって充てん材料を運ぶ方法で,流速,流量によって粒度,運搬量が異なってくる。気流の発生には1~4atmの圧縮空気を流出させ,管径150~200mm,充てん能力20~80m3/h,空気消費量は材料1m3当り自由空気で80~200m3,運搬距離は200~800mがふつうである。…
