螺旋输送(song)机具(ju)有以(yi)下(xia)特(te)点

　　1.结构比较简单(dan)，成(cheng)本较低。

　　2.工作可靠，维护管理(li)简便(bian)。

　　3.尺寸紧(jin)凑(cou)，断(duan)面尺寸小(xiao)，占地(di)面积(ji)小(xiao)。在港口的卸(xie)车(che)卸(xie)船作业中易进出舱口、车(che)厢。

　　4．能实(shi)现(xian)密封输送，有利于输送易飞扬的、炽(chi)热的及气味强烈的物料(liao)，可减(jian)小(xiao)对环境(jing)的污染，改善港(gang)口工(gong)人(ren)的作业条(tiao)件。

　　5．装载(zai)卸载(zai)方便。水平螺旋输(shu)送(song)机(ji)(ji)可(ke)在(zai)其输(shu)送(song)线(xian)路上的(de)任一点装载(zai)卸载(zai);对垂直螺旋输(shu)送(song)机(ji)(ji)配置相对螺旋式取(qu)料装置可(ke)具有优良的(de)取(qu)料性能。

　　6．能逆(ni)向(xiang)(xiang)输(shu)送(song)，也可使一(yi)台(tai)输(shu)送(song)机(ji)同时向(xiang)(xiang)两个方向(xiang)(xiang)输(shu)送(song)物料，即集向(xiang)(xiang)中(zhong)心或远离中(zhong)心。

　　7．单位能耗较(jiao)大(da)。

　　8．物料(liao)在(zai)输送过程中易于研碎(sui)及磨(mo)损，螺旋叶片和料(liao)槽的磨(mo)损也较为严重。
