          雷蒙磨的基本結(jié)構(gòu) 
          1.雷蒙磨基本結(jié)構(gòu)。雷蒙磨粉機是由三組滾子、磨環(huán)及攪拌犁組成,附屬設(shè)備由一臺向磨粉腔鼓風的風機及一臺向三個滾子懸軸內(nèi)腔送風的小風機組成。三組滾子懸掛在旋轉(zhuǎn)托架上,旋轉(zhuǎn)托架的轉(zhuǎn)動帶動三組滾子在磨環(huán)上滾動;旋轉(zhuǎn)托架由電機經(jīng)皮帶輪、傘齒輪副帶動。煅后石油焦進入磨粉腔后,不斷被滾壓成粉料后,隨鼓風流向集粉倉。傘齒輪箱的潤滑泵壓力為550~870kPa,對傘齒輪副強制潤滑。三組滾子的潤滑原設(shè)計是由小風機向懸軸腔傳送帶潤滑油滴的連續(xù)風潤滑。
          2.雷蒙磨使用特點:
          (1)主要部件作業(yè)環(huán)境風流大、粉塵大;
          (2)滾子和磨環(huán)是磨損元件,應(yīng)滿足一定的使用周期;
          (3)滾子工作溫度在120~150℃,潤滑狀態(tài)應(yīng)穩(wěn)定。 
          雷蒙磨粉機常見故障 
          (1)潤滑泵給油不暢;
          (2)連接滾子組件的風管磨穿;
          (3)雷蒙磨粉機電流過大。懸軸部件經(jīng)常發(fā)生滾子轉(zhuǎn)不動,電流高達250-160A(正常180-200A);
          (4)攪拌犁易磨損;
          (5)傳動大皮帶輪漏油嚴重;
          (6)磨粉腔聲音異常,滾子在磨環(huán)上有撞擊聲;
          (7)滾子和磨環(huán)不正常的磨損。滾子表面易磨成凹型面,有時發(fā)現(xiàn)有高低不平的條紋出現(xiàn),磨環(huán)也出現(xiàn)凹型磨面。
          雷蒙磨粉機原因分析 
          1.磨粉腔,經(jīng)停機打開磨粉腔,用手動盤車發(fā)現(xiàn)有的滾子時轉(zhuǎn)時而不轉(zhuǎn)、滾子及磨環(huán)有崩塊。分析是滾子軸承潤滑不良造成。
          2.懸軸部件,經(jīng)解體發(fā)現(xiàn)懸軸的滑動軸承抱死,懸軸腔內(nèi)有大量的油泥。原因是出風口間隙過大,懸軸內(nèi)腔的氣壓小于磨粉腔的氣壓,使粉塵進入懸軸腔內(nèi)。
