三(san)筒(tong)(tong)烘(hong)干(gan)(gan)機是由三(san)個不同直徑的(de)同心圓筒(tong)(tong)體(ti)相嵌組合而成，濕基石英砂(sha)(sha)(sha)從烘(hong)干(gan)(gan)機內(nei)筒(tong)(tong)喂入(ru)，通(tong)過筒(tong)(tong)體(ti)的(de)回轉，石英砂(sha)(sha)(sha)被有傾料(liao)角度的(de)揚(yang)料(liao)板(ban)揚(yang)起并作(zuo)縱(zong)向(xiang)(xiang)運(yun)(yun)(yun)動，當石英砂(sha)(sha)(sha)到達內(nei)筒(tong)(tong)的(de)尾(wei)端(duan)時，在(zai)(zai)自(zi)重的(de)作(zuo)用落入(ru)中(zhong)筒(tong)(tong)，通(tong)過中(zhong)筒(tong)(tong)內(nei)的(de)反(fan)向(xiang)(xiang)揚(yang)料(liao)板(ban)的(de)作(zuo)用，石英砂(sha)(sha)(sha)向(xiang)(xiang)進(jin)料(liao)端(duan)運(yun)(yun)(yun)動至中(zhong)筒(tong)(tong)前(qian)端(duan)，在(zai)(zai)重力作(zuo)用下落入(ru)外筒(tong)(tong)，在(zai)(zai)外管正向(xiang)(xiang)揚(yang)料(liao)板(ban)作(zuo)用下，石英砂(sha)(sha)(sha)向(xiang)(xiang)尾(wei)端(duan)運(yun)(yun)(yun)動，直到外筒(tong)(tong)尾(wei)端(duan)卸出。在(zai)(zai)石英砂(sha)(sha)(sha)往復運(yun)(yun)(yun)動過程中(zhong)與并流的(de)熱煙氣充分接觸，完成熱交換實現石英砂(sha)(sha)(sha)烘(hong)干(gan)(gan)。

產品優點：

烘(hong)于過程中、中筒(tong)(tong)(tong)對內(nei)筒(tong)(tong)(tong)進(jin)行保溫(wen)(wen)、外筒(tong)(tong)(tong)對中筒(tong)(tong)(tong)進(jin)行保溫(wen)(wen)，熱能散失少(shao)，節能;三筒(tong)(tong)(tong)體(ti)同(tong)心圓(yuan)結(jie)構(gou)緊湊，水平布置，設(she)備運行穩定(ding)，銷齒傳動，電耗低;占(zhan)地面積小，安裝(zhuang)周(zhou)期(qi)短，土建投資少(shao)。

產能不宜過(guo)大，一(yi)般僅適用100T/h以下石英砂的干燥。

烘干過程中(zhong)(zhong)，煙氣中(zhong)(zhong)的雜質(zhi)(zhi)對石英(ying)砂的濁度(du)影響大。一般以天然氣、工業醇(chun)類等(deng)潔(jie)凈燃(ran)料為宜;對煤、生物質(zhi)(zhi)等(deng)燃(ran)料容易(yi)對成(cheng)品(pin)石英(ying)砂產生污染。
