粉(fen)體氣力輸送設備(bei)也(ye)稱為(wei)氣力輸(shu)(shu)送(song)(song)泵(beng)(送(song)(song)粉(fen)機)是采用(yong)正壓氣力輸(shu)(shu)送(song)(song)方式輸(shu)(shu)送(song)(song)粉(fen)末狀物(wu)(wu)料，適用(yong)于電廠粉(fen)煤灰輸(shu)(shu)送(song)(song)、水泥生料輸(shu)(shu)送(song)(song)、礦粉(fen)輸(shu)(shu)送(song)(song)、石膏粉(fen)輸(shu)(shu)送(song)(song)、高嶺(ling)土輸(shu)(shu)送(song)(song)、氧(yang)化鋁粉(fen)輸(shu)(shu)送(song)(song)、食品(pin)級物(wu)(wu)料輸(shu)(shu)送(song)(song)等輸(shu)(shu)送(song)(song)，可(ke)根據具體地形(xing)布(bu)置輸(shu)(shu)送(song)(song)管道，實現集中、分散、大高度(du)、長(chang)距(ju)離輸(shu)(shu)送(song)(song)，輸(shu)(shu)送(song)(song)過程不受(shou)氣侯條件影響，能確保物(wu)(wu)料不受(shou)潮，利于生產和環境保護。

    粉體輸送是個既經典又新(xin)興的(de)題。從發展之初到(dao)現(xian)在已經出現(xian)了多種輸送裝置，主要有機(ji)械(xie)輸送和氣流輸送兩種。

    機(ji)械(xie)輸(shu)(shu)(shu)送(song)裝(zhuang)置(zhi)包(bao)括：皮（鏈）帶輸(shu)(shu)(shu)送(song)機(ji)、斗式提升機(ji)和(he)(he)螺旋輸(shu)(shu)(shu)送(song)機(ji)等(deng)；氣(qi)流輸(shu)(shu)(shu)送(song)裝(zhuang)置(zhi)包(bao)括：空氣(qi)斜槽、氣(qi)力提升機(ji)、倉式泵(beng)(beng)和(he)(he)富勒泵(beng)(beng)等(deng)。同機(ji)械(xie)輸(shu)(shu)(shu)送(song)裝(zhuang)置(zhi)比起(qi)來，氣(qi)流輸(shu)(shu)(shu)送(song)裝(zhuang)置(zhi)有(you)其獨特的(de)(de)(de)優(you)點：輸(shu)(shu)(shu)送(song)線(xian)路敷設自由，運行(xing)可靠，無粉塵飛揚，輸(shu)(shu)(shu)送(song)距離長，沒有(you)復雜和(he)(he)昂貴的(de)(de)(de)傳動裝(zhuang)置(zhi)，檢(jian)修(xiu)時間(jian)和(he)(he)費(fei)用也較少。因此，氣(qi)流輸(shu)(shu)(shu)送(song)得到了(le)廣泛的(de)(de)(de)應用。

    粉體氣力(li)輸送設備具有防塵效果*；便于實(shi)現機械(xie)化(hua)、自動(dong)化(hua)，可(ke)減輕勞(lao)動(dong)強(qiang)度(du)，節省(sheng)人力；在(zai)輸送過程(cheng)中(zhong)，可(ke)以同時進行多種工(gong)藝(yi)作，如混合、粉碎、分選、干燥、冷卻；防止物料(liao)受潮、污染(ran)或混入雜物等優點，因而在(zai)鑄造(zao)、冶金、化(hua)工(gong)、建材、糧食(shi)加工(gong)等部門都得到(dao)應用。它的主要缺(que)點是動(dong)力消(xiao)耗較(jiao)大(da)；設備(主(zhu)要是分(fen)離(li)器(qi)人口)和管道(主(zhu)要是彎(wan)頭)磨損較(jiao)快，如果設計(ji)、施(shi)工或(huo)運轉不(bu)當，則容易(yi)(yi)造成物料沉積(ji)，以(yi)致(zhi)堵塞(sai)，使輸送中斷(duan)；不(bu)宜輸送濕度大(da)、黏性大(da)或(huo)易(yi)(yi)破碎(sui)的(de)物料等。
