脫硫(liu)石(shi)膏烘(hong)干機主要由筒體裝(zhuang)(zhuang)置(zhi)(zhi)前后(hou)托輪(lun)裝(zhuang)(zhuang)置(zhi)(zhi)、進(jin)(jin)出(chu)(chu)料裝(zhuang)(zhuang)置(zhi)(zhi)、傳動裝(zhuang)(zhuang)置(zhi)(zhi)與齒(chi)輪(lun)罩等部件(jian)組成。與烘(hong)(hong)干機(ji)配套的附屬(shu)設(she)備：燃(ran)燒室、喂料出(chu)(chu)料設(she)備、收塵(chen)設(she)備等均不屬(shu)本機(ji)范圍脫硫石(shi)膏烘(hong)(hong)干機(ji)也(ye)叫(jiao)石(shi)膏烘(hong)(hong)干機(ji)，烘(hong)(hong)干機(ji)廣(guang)泛用于水泥、礦山、建材(cai)、化工(gong)(gong)、糧食、復合肥生(sheng)產等行業的物料烘(hong)(hong)干，為了控制(zhi)(zhi)烘(hong)(hong)干機(ji)的溫度(du)，在進(jin)(jin)出(chu)(chu)料裝(zhuang)(zhuang)置(zhi)(zhi)上配置(zhi)(zhi)熱電偶(ou)，通過溫度(du)表可顯示烘(hong)(hong)干機(ji)進(jin)(jin)出(chu)(chu)料端的溫度(du)變(bian)化，為更(geng)好地控制(zhi)(zhi)筒體內(nei)的工(gong)(gong)作溫度(du)（一般350-380度(du)）提供了依據。

　　脫硫石膏(gao)烘干機的(de)(de)(de)熱(re)源(yuan)來自燃燒(shao)裝置，本烘(hong)(hong)干(gan)機(ji)(ji)采用順流(liu)式(shi)加熱(re)方(fang)式(shi)。因此需要(yao)烘(hong)(hong)干(gan)的(de)(de)(de)物(wu)料(liao)，從進料(liao)箱、進料(liao)溜(liu)進入筒體，即被螺旋抄板(ban)推向(xiang)后。由于烘(hong)(hong)干(gan)機(ji)(ji)傾斜放置，物(wu)料(liao)一方(fang)面在重力和回轉(zhuan)作用下流(liu)向(xiang)后端，另一方(fang)面物(wu)料(liao)被抄板(ban)反復抄起，帶至上(shang)端再不斷地揚(yang)撒下來，使物(wu)料(liao)在筒內形(xing)成均勻的(de)(de)(de)幕簾，充(chong)分(fen)與筒內的(de)(de)(de)熱(re)氣流(liu)進行熱(re)交換，由于物(wu)料(liao)反復揚(yang)撒，所含(han)的(de)(de)(de)水分(fen)逐漸被烘(hong)(hong)干(gan)，從而達到烘(hong)(hong)干(gan)的(de)(de)(de)目的(de)(de)(de)。
