工作原理
　　當螺旋軸轉動時，由于物料的重力及其與槽體壁所產生的摩擦力，使物料只能在葉片的推送下沿著輸送機的槽底向前移動，其情況好像不能旋轉的螺母沿著旋轉的螺桿作平移運動一樣。物料的主要前進動力是來自螺旋葉片在軸向旋轉時將物料沿葉片切線方向向上和向前的作用力。
　　為了(le)使螺旋(xuan)(xuan)(xuan)軸處于較為有(you)利(li)的(de)(de)(de)受(shou)拉(la)狀態(tai)，一(yi)般都(dou)將(jiang)(jiang)驅動裝置和卸料(liao)口(kou)安(an)放(fang)在(zai)(zai)(zai)輸(shu)(shu)(shu)送(song)機(ji)的(de)(de)(de)同一(yi)端，而(er)(er)把進料(liao)口(kou)盡量(liang)放(fang)在(zai)(zai)(zai)另一(yi)端的(de)(de)(de)尾部(bu)附近。 旋(xuan)(xuan)(xuan)轉(zhuan)的(de)(de)(de)螺旋(xuan)(xuan)(xuan)葉(xie)片(pian)將(jiang)(jiang)物(wu)(wu)料(liao)推(tui)移而(er)(er)進行輸(shu)(shu)(shu)送(song)，使物(wu)(wu)料(liao)不與螺旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)送(song)機(ji)葉(xie)片(pian)一(yi)起旋(xuan)(xuan)(xuan)轉(zhuan)的(de)(de)(de)力是物(wu)(wu)料(liao)自身重量(liang)和螺旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)送(song)機(ji)機(ji)殼對物(wu)(wu)料(liao)的(de)(de)(de)摩擦阻力。葉(xie)片(pian)的(de)(de)(de)面型根據輸(shu)(shu)(shu)送(song)物(wu)(wu)料(liao)的(de)(de)(de)不同有(you)實體面型、帶式面型、葉(xie)片(pian)面型等(deng)型式。螺旋(xuan)(xuan)(xuan)輸(shu)(shu)(shu)送(song)機(ji)的(de)(de)(de)螺旋(xuan)(xuan)(xuan)軸在(zai)(zai)(zai)物(wu)(wu)料(liao)運(yun)動方(fang)向的(de)(de)(de)終端有(you)止推(tui)軸承(cheng)以隨物(wu)(wu)料(liao)給螺旋(xuan)(xuan)(xuan)的(de)(de)(de)軸向反力，在(zai)(zai)(zai)機(ji)長較長時，應加(jia)中間吊掛軸承(cheng)。

　　應用范圍
　　螺旋機廣泛應用于各行業，如建材、化工、電力、冶金、煤礦炭、糧食等行業，適用于水平或傾斜輸送粉狀、粒狀和小塊狀物料，如煤礦、灰、渣、水泥、糧食等，物料溫度小于200℃。螺旋機不適于輸送易變質的、粘性大的、易結塊的物料。在混凝土攪拌站中,螺旋輸送機的作用得到了更大的體現。
　　(1)螺旋輸送機是在化工、建材、糧食等部門中廣泛應用的一種輸送設備，主要用于輸送粉狀、顆粒狀和小塊狀物料。它不適宜輸送易變質的、粘性的和易結塊的物料。
　　（2）螺旋輸送機使用的環境溫度為—20~50℃ ；輸送機的傾角β≤20°；輸送長度一般小于40m，長不超過70m。
　　（3）螺旋輸(shu)送與(yu)其(qi)他輸(shu)送設(she)備相比較，具(ju)有結構簡(jian)單(dan)、橫截面(mian)尺寸小、密封性能好(hao)、可以中間(jian)多點裝料(liao)和卸料(liao)、操作安全方便以及(ji)制造成本低等優點。它的缺點是機(ji)件磨(mo)損較嚴重、輸(shu)送量較低、消(xiao)耗功率大以及(ji)物料(liao)在運輸(shu)過程易被破碎。
