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(san)筒烘干機產(chan)品概況及性(xing)能特點
1、技術含量高,中、內筒(tong)自(zi)我保溫能(neng)力(li)強,熱能(neng)利用率高,出口溫度低(di),大大延(yan)長(chang)了除塵器(qi)的使用壽命。
2、針對內、中、外筒不(bu)同區域(yu)分別采用不(bu)同技(ji)術的新型揚(yang)料裝置,可將揚(yang)料效率,有(you)效的消除“風洞”帶來(lai)的熱(re)(re)損失(shi),增加物料與熱(re)(re)氣流(liu)的接(jie)觸率,提高(gao)烘干效率。
3、占地面積省,采用(yong)整體支架,安(an)裝方(fang)便,故(gu)障(zhang)率少,維護(hu)方(fang)便,運行(xing)可靠(kao),基礎投資(zi)省。
4、進、出(chu)料裝(zhuang)置采用特殊結構軟密(mi)封,漏風率小。
5、工藝流程可采用順流或(huo)逆流。
6、優(you)化的結構設計(ji)、耐磨耐熱處理(li)技術,為烘干機的長期、無故障(zhang)運(yun)行奠定了基礎。
7、根據物料性質的不同,采用調速電(dian)機或變頻器來合(he)理調節筒體轉速以提高烘(hong)干效率。
