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型三筒烘干機(ji)產品概(gai)況及性能特點
1、技術含(han)量高，中、內筒自(zi)我保溫(wen)能力(li)強，熱能利用(yong)率高，出口溫(wen)度低，大大延長了除塵器的(de)使用(yong)壽(shou)命。
2、針對(dui)內、中、外筒不同區域(yu)分別采用(yong)不同技術(shu)的新型(xing)揚料裝置，可(ke)將揚料效率(lv)，有效的消除“風洞”帶來的熱(re)損失，增加物料與(yu)熱(re)氣(qi)流的接(jie)觸(chu)率(lv)，提高烘干(gan)效率(lv)。
3、占地面積(ji)省(sheng)，采(cai)用整體(ti)支架，安裝方便，故障率少，維護方便，運行可靠，基礎(chu)投資省(sheng)。
4、進、出料裝(zhuang)置采用特殊結構軟密封，漏風率小。
5、工(gong)藝流程可采用順流或逆流。
6、優化的結(jie)構設計、耐(nai)磨耐(nai)熱處理技術，為(wei)烘干機(ji)的長期、無(wu)故障運行奠定了基礎。
7、根據(ju)物料性質的不(bu)同，采用調(diao)速電機或變頻器來合理調(diao)節(jie)筒體轉(zhuan)速以(yi)提高烘干效(xiao)率。
