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(jin)行螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)輸送(song)(song)機(ji)輸送(song)(song),使物(wu)料(liao)(liao)不(bu)與(yu)螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)輸送(song)(song)機(ji)葉片(pian)(pian)一起(qi)旋(xuan)(xuan)轉的(de)力是(shi)物(wu)料(liao)(liao)自身重量和螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)輸送(song)(song)機(ji)機(ji)殼對物(wu)料(liao)(liao)的(de)摩擦阻力.螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)輸送(song)(song)機(ji)旋(xuan)(xuan)轉軸上焊(han)的(de)螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)葉片(pian)(pian),葉片(pian)(pian)的(de)面(mian)型(xing)(xing)(xing)根(gen)據輸送(song)(song)物(wu)料(liao)(liao)的(de)不(bu)同有實體(ti)面(mian)型(xing)(xing)(xing)、帶(dai)式(shi)面(mian)型(xing)(xing)(xing)、葉片(pian)(pian)面(mian)型(xing)(xing)(xing)等型(xing)(xing)(xing)式(shi).螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)輸送(song)(song)機(ji)的(de)螺(luo)(luo)(luo)(luo)旋(xuan)(xuan)軸在物(wu)料(liao)(liao)運(yun)動(dong)方向的(de)終端(duan)有止(zhi)推軸承以隨物料給螺旋的軸向(xiang)反力,在機長較長時,應(ying)加中間吊掛(gua)軸承.
