目前現有的人(ren)工(gong)(gong)砂(sha)(sha)(sha)產品(pin)線，都(dou)采(cai)用濕法生產工(gong)(gong)藝(yi)，成(cheng)品(pin)砂(sha)(sha)(sha)經洗砂(sha)(sha)(sha)機(ji)后含水(shui)量較高(gao)，細(xi)砂(sha)(sha)(sha)（0.16mm以下顆粒)流失嚴(yan)重，有的甚至流失20%以上，這不(bu)但損失嚴(yan)重，而(er)且還嚴(yan)重影響(xiang)砂(sha)(sha)(sha)子(zi)的級配(pei)，造成(cheng)級配(pei)不(bu)合理，細(xi)度(du)(du)模數偏粗，大大降低了機(ji)制砂(sha)(sha)(sha)的產品(pin)質量，過多的細(xi)沙(sha)排放(fang)，還會造成(cheng)環(huan)(huan)境污染。隨著(zhu)環(huan)(huan)境的日(ri)益惡劣，各地(di)對排污行為加大了監管(guan)力(li)度(du)(du)，以及(ji)基礎建設(she)加快造成(cheng)的砂(sha)(sha)(sha)石需求的加大，一體(ti)機(ji)廣泛(fan)運用于水(shui)電站(zhan)砂(sha)(sha)(sha)石骨科(ke)加工(gong)(gong)系統(tong)、玻璃原材料(liao)加工(gong)(gong)系統(tong)、人(ren)工(gong)(gong)制砂(sha)(sha)(sha)生產線、選(xuan)煤廠粗泥(ni)煤的回收及(ji)環(huan)(huan)保(bao)工(gong)(gong)程（泥(ni)漿凈化）等成(cheng)品(pin)砂(sha)(sha)(sha)的脫水(shui)及(ji)細(xi)砂(sha)(sha)(sha)回收。
