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特點

3、占(zhan)地面(mian)積省，采(cai)用(yong)整(zheng)體支架(jia)，安裝方(fang)便(bian)，故障率少，維護方(fang)便(bian)，運行可靠，基礎投資省。
4、進、出(chu)料裝置采(cai)用(yong)特殊結(jie)構軟密封(feng)，漏風率(lv)小。
5、工藝流(liu)程可采用順流(liu)或逆流(liu)。
6、優化的(de)結構設計、耐(nai)(nai)磨(mo)耐(nai)(nai)熱處理技(ji)術，為烘(hong)干機的(de)長期、無故障運行奠定了基(ji)礎。
7、根據物(wu)料性質的(de)不(bu)同(tong)，采用調(diao)速(su)電機或變頻(pin)器來(lai)合(he)理調(diao)節筒體轉速(su)以提高烘干效(xiao)率。
工作(zuo)原理
XDS三筒(tong)(tong)(tong)(tong)(tong)(tong)烘干(gan)(gan)機是一(yi)種水平(ping)安裝(zhuang)的組合烘干(gan)(gan)機，筒(tong)(tong)(tong)(tong)(tong)(tong)體(ti)依靠4個驅動(dong)輪支撐并(bing)摩(mo)擦傳動(dong)筒(tong)(tong)(tong)(tong)(tong)(tong)體(ti)輪帶。筒(tong)(tong)(tong)(tong)(tong)(tong)體(ti)的入(ru)料(liao)(liao)(liao)(liao)(liao)(liao)端(duan)(duan)設有熱風爐裝(zhuang)置，當被(bei)烘干(gan)(gan)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)進(jin)入(ru)內(nei)筒(tong)(tong)(tong)(tong)(tong)(tong)后(hou)，在(zai)內(nei)筒(tong)(tong)(tong)(tong)(tong)(tong)螺旋(xuan)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)推(tui)動(dong)下進(jin)入(ru)內(nei)筒(tong)(tong)(tong)(tong)(tong)(tong)斜(xie)軸向(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)，在(zai)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)帶動(dong)下形(xing)成斜(xie)軸向(xiang)(xiang)均勻(yun)料(liao)(liao)(liao)(liao)(liao)(liao)幕同(tong)時推(tui)動(dong)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)前(qian)進(jin)；物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)進(jin)入(ru)中筒(tong)(tong)(tong)(tong)(tong)(tong)后(hou)，在(zai)弧形(xing)斜(xie)徑向(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)作用下，形(xing)成斜(xie)徑向(xiang)(xiang)均勻(yun)前(qian)進(jin)料(liao)(liao)(liao)(liao)(liao)(liao)幕；物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)進(jin)入(ru)外筒(tong)(tong)(tong)(tong)(tong)(tong)后(hou)，在(zai)外筒(tong)(tong)(tong)(tong)(tong)(tong)多(duo)點徑向(xiang)(xiang)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)板(ban)作用下，形(xing)成多(duo)點徑向(xiang)(xiang)料(liao)(liao)(liao)(liao)(liao)(liao)幕，并(bing)向(xiang)(xiang)出料(liao)(liao)(liao)(liao)(liao)(liao)端(duan)(duan)移(yi)動(dong)；出料(liao)(liao)(liao)(liao)(liao)(liao)端(duan)(duan)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)落在(zai)出料(liao)(liao)(liao)(liao)(liao)(liao)錐上進(jin)入(ru)出料(liao)(liao)(liao)(liao)(liao)(liao)螺旋(xuan)筒(tong)(tong)(tong)(tong)(tong)(tong)，再落入(ru)出料(liao)(liao)(liao)(liao)(liao)(liao)罩排(pai)出。熱煙(yan)氣在(zai)揚(yang)料(liao)(liao)(liao)(liao)(liao)(liao)過程(cheng)中與(yu)物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)充(chong)分進(jin)行熱交換，物(wu)(wu)(wu)料(liao)(liao)(liao)(liao)(liao)(liao)所含水份蒸發后(hou)被(bei)氣流帶走。
