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移而進行(xing)螺(luo)(luo)(luo)旋(xuan)輸送(song)(song)機(ji)(ji)輸送(song)(song),使物料(liao)(liao)不與(yu)螺(luo)(luo)(luo)旋(xuan)輸送(song)(song)機(ji)(ji)葉片(pian)(pian)一起(qi)旋(xuan)轉的(de)(de)力是(shi)物料(liao)(liao)自身重量和螺(luo)(luo)(luo)旋(xuan)輸送(song)(song)機(ji)(ji)機(ji)(ji)殼對物料(liao)(liao)的(de)(de)摩擦阻力.螺(luo)(luo)(luo)旋(xuan)輸送(song)(song)機(ji)(ji)旋(xuan)轉軸上焊的(de)(de)螺(luo)(luo)(luo)旋(xuan)葉片(pian)(pian),葉片(pian)(pian)的(de)(de)面(mian)型根(gen)據輸送(song)(song)物料(liao)(liao)的(de)(de)不同有(you)(you)實(shi)體面(mian)型、帶式(shi)面(mian)型、葉片(pian)(pian)面(mian)型等型式(shi).螺(luo)(luo)(luo)旋(xuan)輸送(song)(song)機(ji)(ji)的(de)(de)螺(luo)(luo)(luo)旋(xuan)軸在物料(liao)(liao)運(yun)動(dong)方向的(de)(de)終(zhong)端(duan)有(you)(you)止(zhi)推軸承以隨物料給螺旋的(de)軸向反力,在(zai)機長較長時,應加中(zhong)間吊掛軸承.
