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(tong)烘干機產(chan)品概況(kuang)及(ji)性能特點
1、技術含量高,中、內(nei)筒(tong)自我保溫能力強,熱能利用(yong)率(lv)高,出口溫度低,大大延長了除塵器的使用(yong)壽(shou)命(ming)。
2、針(zhen)對內、中、外筒不同區域分別采用不同技術的(de)新型揚料裝置,可將(jiang)揚料效(xiao)率,有(you)效(xiao)的(de)消除“風洞”帶來的(de)熱(re)損失,增加物料與熱(re)氣流的(de)接觸率,提高(gao)烘干效(xiao)率。
3、占地(di)面積(ji)省,采用整體(ti)支架(jia),安裝方(fang)便(bian),故(gu)障率少,維護方(fang)便(bian),運行可靠,基礎投資省。
4、進、出料裝置(zhi)采用(yong)特殊結構軟密封,漏風率小。
5、工藝流(liu)程可采用順流(liu)或逆流(liu)。
6、優(you)化(hua)的結構設計、耐磨耐熱(re)處理(li)技術(shu),為(wei)烘干機的長期、無故障運(yun)行奠定了(le)基礎。
7、根據(ju)物料性質的不同,采用調(diao)速電機或變頻器(qi)來(lai)合理調(diao)節筒體轉速以提高烘干效率。
