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型三筒烘干機產品概況及性能(neng)特點(dian)
1、技(ji)術(shu)含(han)量高，中、內筒自(zi)我保(bao)溫(wen)能(neng)力強，熱能(neng)利用率高，出(chu)口溫(wen)度低，大大延(yan)長了除塵(chen)器的使(shi)用壽命。
2、針對內、中、外(wai)筒不(bu)同區域(yu)分別(bie)采用(yong)不(bu)同技術的新型(xing)揚料裝置，可將揚料效率，有效的消除(chu)“風(feng)洞(dong)”帶來(lai)的熱(re)損失，增加物料與(yu)熱(re)氣流的接觸率，提高烘(hong)干(gan)效率。
3、占地(di)面積省，采(cai)用整體(ti)支架，安裝(zhuang)方便，故(gu)障率少(shao)，維護(hu)方便，運行可靠(kao)，基(ji)礎投資(zi)省。
4、進、出料(liao)裝置采用(yong)特殊結構軟(ruan)密封，漏風(feng)率小。
5、工藝流程可采(cai)用順流或逆流。
6、優化的結(jie)構設計、耐磨耐熱處理技術(shu)，為烘(hong)干機(ji)的長期、無故障(zhang)運行奠定(ding)了(le)基礎。
7、根據物料性質的(de)不同，采用調(diao)速(su)電機或(huo)變(bian)頻(pin)器來合理調(diao)節筒體轉(zhuan)速(su)以提高烘干效率。
