螺旋輸送機在輸送形式上分為有軸螺旋輸送機和無軸螺旋輸送機兩種,在外型上分為u型螺旋輸送機和管式螺旋輸送機.有軸螺旋輸送機適用于無粘性的干粉物料和小顆粒物料.(例如:水泥、粉煤灰、石灰、糧等)而無軸螺旋輸送機適合輸送機由粘性的和易纏繞的物料.(例如:污泥、生物質、垃圾等)螺旋輸送機的工作原理是旋轉的螺旋葉片將物料推(tui)移而進(jin)行螺旋(xuan)(xuan)輸送(song)(song)(song)機輸送(song)(song)(song),使物(wu)(wu)料(liao)(liao)(liao)不(bu)與(yu)螺旋(xuan)(xuan)輸送(song)(song)(song)機葉片一起旋(xuan)(xuan)轉(zhuan)(zhuan)的(de)力是(shi)物(wu)(wu)料(liao)(liao)(liao)自身重(zhong)量(liang)和螺旋(xuan)(xuan)輸送(song)(song)(song)機機殼對物(wu)(wu)料(liao)(liao)(liao)的(de)摩擦阻力.螺旋(xuan)(xuan)輸送(song)(song)(song)機旋(xuan)(xuan)轉(zhuan)(zhuan)軸上焊的(de)螺旋(xuan)(xuan)葉片,葉片的(de)面(mian)(mian)(mian)型根據輸送(song)(song)(song)物(wu)(wu)料(liao)(liao)(liao)的(de)不(bu)同(tong)有(you)實(shi)體面(mian)(mian)(mian)型、帶式面(mian)(mian)(mian)型、葉片面(mian)(mian)(mian)型等型式.螺旋(xuan)(xuan)輸送(song)(song)(song)機的(de)螺旋(xuan)(xuan)軸在(zai)物(wu)(wu)料(liao)(liao)(liao)運動方(fang)向的(de)終端有(you)止推(tui)軸承以隨物(wu)料給螺旋的(de)軸向反(fan)力,在機長(chang)較長(chang)時(shi),應(ying)加中間(jian)吊掛軸承.
