　　應用范圍

　　螺(luo)旋輸(shu)送機廣泛應用于各(ge)行業(ye)，如(ru)(ru)建材、化工、電力、冶金(jin)、煤(mei)礦炭、糧食等(deng)行業(ye)，適用于水(shui)平或(huo)傾斜輸(shu)送粉狀、粒狀和(he)小塊狀物(wu)料，如(ru)(ru)煤(mei)礦、灰、渣、水(shui)泥、糧食等(deng)，物(wu)料溫度小于200℃。螺(luo)旋機不適于輸(shu)送易變質的、粘性大的、易結塊的物(wu)料。在混凝土(tu)攪拌(ban)站(zhan)中,螺(luo)旋輸(shu)送機的作用得(de)到(dao)了體(ti)現 [5]  .

　　(1)螺旋輸(shu)送(song)機(ji)是在(zai)化(hua)工、建材、糧食等部門中廣泛(fan)應用的(de)一種輸(shu)送(song)設備(bei)，主要用于輸(shu)送(song)粉狀、顆粒狀和小塊(kuai)狀物(wu)料。它不適宜(yi)輸(shu)送(song)易(yi)變質的(de)、粘性的(de)和易(yi)結塊(kuai)的(de)物(wu)料。

　　（2）螺旋(xuan)輸(shu)送機使用(yong)的(de)環境溫度為—20~50℃ ；輸(shu)送機的(de)傾角β≤20°；輸(shu)送長(chang)度一般小(xiao)于40m，不(bu)超過70m。

　　（3）螺旋輸(shu)送機與其他輸(shu)送設備相(xiang)比較(jiao)(jiao)，具有結構簡單(dan)、橫(heng)截面尺寸小、密封性能(neng)好、可以中間多(duo)點裝料(liao)和卸料(liao)、操作(zuo)方便以及制造成本(ben)低等優點。它的缺點是機件磨損較(jiao)(jiao)嚴重、輸(shu)送量(liang)較(jiao)(jiao)低、消耗功率大以及物(wu)料(liao)在運(yun)輸(shu)過程易被(bei)破碎。
