XDS型三筒烘干機主要用于烘干一定濕度范圍內顆粒物料如干粉砂漿行業中所用的黃砂;鑄造行業中的型砂;建材行業中的高爐礦渣、礦渣、粘土、煤、鐵粉等;化工行業中的不起化學反應、不怕高溫及污染的小顆粒等,烘干后的物料終水份可任意控制。沙子烘干機一般適應于顆粒狀物料。特別是烘干沙子、河沙、石英砂等烘干效果好。河沙沙子烘干機的優點是生產能力大、適用范圍廣、流量阻力小、操作上允許波動范圍較大、操作方便等。常用于烘干河沙、人工砂、石英砂、礦粉、煤渣等。
XDS型三筒烘干(gan)機產品概況及性能特點
1、技術含量高,中(zhong)、內(nei)筒自我(wo)保溫能(neng)力(li)強,熱能(neng)利用率高,出口溫度低,大(da)大(da)延長了(le)除塵(chen)器的使用壽命(ming)。
2、針對內、中、外筒(tong)不同區域分別采(cai)用不同技(ji)術(shu)的(de)新型揚(yang)料裝置,可將揚(yang)料效(xiao)(xiao)率,有(you)效(xiao)(xiao)的(de)消除“風洞”帶來的(de)熱損失,增加物(wu)料與熱氣(qi)流(liu)的(de)接觸率,提(ti)高烘干效(xiao)(xiao)率。
3、占地(di)面(mian)積省,采用整體(ti)支架,安裝(zhuang)方便(bian),故(gu)障率少,維護方便(bian),運行可靠,基(ji)礎投資省。
4、進、出料(liao)裝置采(cai)用特殊結構軟密封,漏風率(lv)小(xiao)。
5、工藝流程(cheng)可采用順(shun)流或(huo)逆流。
6、優化的(de)結構設計、耐磨耐熱(re)處理技術,為烘干機(ji)的(de)長期、無故障運行(xing)奠(dian)定(ding)了基礎。
7、根據物料性質的不同,采(cai)用調速電(dian)機或變(bian)頻器(qi)來合理調節(jie)筒體(ti)轉(zhuan)速以提高烘干效率。
