摘要
  氣流磨分為開路和閉路,根據研磨物料和研磨要求的不同可以自由選擇。  閉路循環運行的流化床式氣流磨是一種能實現超微研磨的設備,能將物料研磨到亞微米級。具有產品粒度

  氣流磨分為(wei)開(kai)路和閉路,根據研(yan)(yan)磨物料和研(yan)(yan)磨要求(qiu)的不同可(ke)以自由選擇。

  閉路循環運行的流化床式氣流磨是一種能(neng)實現超微(wei)(wei)研(yan)磨的設(she)備(bei),能(neng)將物(wu)料(liao)(liao)研(yan)磨到亞微(wei)(wei)米(mi)級(ji)。具(ju)有產品粒度均勻(yun)不發熱,磨體無(wu)磨損(sun),無(wu)雜質(zhi)混入(ru),對(dui)環境無(wu)污(wu)染等(deng)特(te)點(dian)。在(zai)(zai)研(yan)磨各種金屬及(ji)化合物(wu),稀(xi)土材料(liao)(liao)以(yi)及(ji)易氧(yang)化材料(liao)(liao)時,不氧(yang)化,不自燃。 閉路循環氣(qi)(qi)(qi)流(liu)磨其基本原理是先開啟加氧(yang)氣(qi)(qi)(qi)(氮氣(qi)(qi)(qi)/高(gao)純空(kong)氣(qi)(qi)(qi))閥(fa),高(gao)純氬(ya)(ya)氣(qi)(qi)(qi)(氮氣(qi)(qi)(qi)/高(gao)純空(kong)氣(qi)(qi)(qi))充入(ru)儲氣(qi)(qi)(qi)罐達到0.6MPa以(yi)上壓力(li),此時手(shou)動關掉加氬(ya)(ya)(氮氣(qi)(qi)(qi)/高(gao)純空(kong)氣(qi)(qi)(qi))閥(fa),點(dian)擊自動運行(xing),設(she)備(bei)按設(she)定(ding)的程序(xu)逐步運行(xing),高(gao)純氬(ya)(ya)氣(qi)(qi)(qi)(氮氣(qi)(qi)(qi)/高(gao)純空(kong)氣(qi)(qi)(qi))進(jin)入(ru)壓縮(suo)機(ji),壓縮(suo)后(hou)(hou)的氣(qi)(qi)(qi)體經(jing)(jing)由(you)磨體下(xia)部(bu)特(te)殊設(she)計而成(cheng)的噴(pen)嘴加速后(hou)(hou),以(yi)超音速氣(qi)(qi)(qi)流(liu)射入(ru)粉碎區,物(wu)料(liao)(liao)在(zai)(zai)高(gao)速氣(qi)(qi)(qi)流(liu)中自身相互(hu)碰撞(zhuang),大顆粒的物(wu)料(liao)(liao)被研(yan)磨為小顆粒,周而復始。經(jing)(jing)研(yan)磨后(hou)(hou)的物(wu)料(liao)(liao)進(jin)入(ru)磨體上部(bu)的分(fen)級(ji)區,自動的將物(wu)料(liao)(liao)進(jin)行(xing)分(fen)級(ji)篩選,合格的物(wu)料(liao)(liao)隨氣(qi)(qi)(qi)流(liu)一起進(jin)入(ru)收(shou)集(ji)裝(zhuang)置。而未被分(fen)級(ji)篩選的粗顆粒又下(xia)落(luo)到研(yan)磨區,“回爐(lu)”繼續參(can)與(yu)研(yan)磨。此過程循環往復,達到超微(wei)(wei)研(yan)磨的目的。由(you)分(fen)級(ji)輪篩選出的合格物(wu)料(liao)(liao)隨氣(qi)(qi)(qi)流(liu)一起進(jin)入(ru)成(cheng)品收(shou)集(ji)裝(zhuang)置。經(jing)(jing)過布(bu)袋(dai)過濾(lv)的氬(ya)(ya)氣(qi)(qi)(qi)(氮氣(qi)(qi)(qi)/高(gao)純空(kong)氣(qi)(qi)(qi))流(liu)經(jing)(jing)過密(mi)封(feng)的管路回到壓縮(suo)機(ji)的入(ru)口(kou)處(含空(kong)氣(qi)(qi)(qi)(粉塵)過濾(lv)檢查裝(zhuang)置),重新進(jin)入(ru)壓縮(suo)機(ji)完成(cheng)閉路循環。
