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)(luo)(luo)旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)(shu)送(song)(song)機(ji)(ji)(ji)(ji)輸(shu)(shu)(shu)(shu)送(song)(song),使(shi)物料(liao)(liao)不與螺(luo)(luo)(luo)旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)(shu)送(song)(song)機(ji)(ji)(ji)(ji)葉(xie)(xie)(xie)片(pian)一(yi)起旋(xuan)(xuan)(xuan)轉的力是物料(liao)(liao)自身(shen)重量(liang)和螺(luo)(luo)(luo)旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)(shu)送(song)(song)機(ji)(ji)(ji)(ji)機(ji)(ji)(ji)(ji)殼對物料(liao)(liao)的摩(mo)擦阻力.螺(luo)(luo)(luo)旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)(shu)送(song)(song)機(ji)(ji)(ji)(ji)旋(xuan)(xuan)(xuan)轉軸上(shang)焊的螺(luo)(luo)(luo)旋(xuan)(xuan)(xuan)葉(xie)(xie)(xie)片(pian),葉(xie)(xie)(xie)片(pian)的面(mian)(mian)(mian)型根據輸(shu)(shu)(shu)(shu)送(song)(song)物料(liao)(liao)的不同有實體(ti)面(mian)(mian)(mian)型、帶式面(mian)(mian)(mian)型、葉(xie)(xie)(xie)片(pian)面(mian)(mian)(mian)型等型式.螺(luo)(luo)(luo)旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)(shu)送(song)(song)機(ji)(ji)(ji)(ji)的螺(luo)(luo)(luo)旋(xuan)(xuan)(xuan)軸在物料(liao)(liao)運動(dong)方向的終端(duan)有止推軸承以隨(sui)物料給螺旋的(de)軸(zhou)(zhou)向反力,在機長較長時,應加中間吊掛(gua)軸(zhou)(zhou)承(cheng).
