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移而進行螺(luo)旋(xuan)(xuan)(xuan)(xuan)輸送(song)(song)機(ji)(ji)輸送(song)(song),使物(wu)料不(bu)與螺(luo)旋(xuan)(xuan)(xuan)(xuan)輸送(song)(song)機(ji)(ji)葉(xie)片一起旋(xuan)(xuan)(xuan)(xuan)轉的(de)力(li)是物(wu)料自身重(zhong)量和螺(luo)旋(xuan)(xuan)(xuan)(xuan)輸送(song)(song)機(ji)(ji)機(ji)(ji)殼對物(wu)料的(de)摩擦(ca)阻力(li).螺(luo)旋(xuan)(xuan)(xuan)(xuan)輸送(song)(song)機(ji)(ji)旋(xuan)(xuan)(xuan)(xuan)轉軸上焊的(de)螺(luo)旋(xuan)(xuan)(xuan)(xuan)葉(xie)片,葉(xie)片的(de)面型根(gen)據輸送(song)(song)物(wu)料的(de)不(bu)同有實(shi)體面型、帶式(shi)面型、葉(xie)片面型等型式(shi).螺(luo)旋(xuan)(xuan)(xuan)(xuan)輸送(song)(song)機(ji)(ji)的(de)螺(luo)旋(xuan)(xuan)(xuan)(xuan)軸在物(wu)料運(yun)動方(fang)向的(de)終端有止(zhi)推軸承以隨物料給(gei)螺旋的軸向反力,在機長較長時,應(ying)加(jia)中間吊掛軸承.
