目前國內(nei)市場上仍有較大一部分(fen)中(zhong)小(xiao)型水泥企業(ye),可以采用(yong)(yong)單臺(tai)磨(mo)機(ji)粉(fen)磨(mo)生產(chan)(chan)線,為了使這種小(xiao)型磨(mo)機(ji)達到高(gao)產(chan)(chan)量(liang)、低電耗之目的,對磨(mo)機(ji)應該采用(yong)(yong)循環粉(fen)磨(mo)、多點(dian)(dian)進料、多點(dian)(dian)取料微(wei)粉(fen)管磨(mo)機(ji),它的特點(dian)(dian)是(shi):
球磨(mo)(mo)機(ji)(ji)廣(guang)泛應用(yong)于建材、化(hua)工、冶金、礦山等行業(ye)的(de)粉磨(mo)(mo)作業(ye)中,老式磨(mo)(mo)機(ji)(ji)的(de)主軸(zhou)承都(dou)采用(yong)滑(hua)(hua)動(dong)(dong)軸(zhou)承(巴氏(shi)合(he)金瓦(wa)),20世(shi)紀80年代(dai)部分(fen)磨(mo)(mo)機(ji)(ji)也有選用(yong)動(dong)(dong)靜壓(ya)軸(zhou)承的(de)(即巴氏(shi)合(he)金瓦(wa)配套(tao)高壓(ya)稀(xi)油(you)啟動(dong)(dong),低壓(ya)稀(xi)油(you)工作)。,理論和實踐證明(ming),滑(hua)(hua)動(dong)(dong)軸(zhou)承的(de)摩擦(ca)系(xi)數在0.04左(zuo)右(you),每(mei)臺磨(mo)(mo)機(ji)(ji)在正常轉動(dong)(dong)時需要克服滑(hua)(hua)動(dong)(dong)軸(zhou)承較(jiao)大(da)的(de)摩擦(ca)阻(zu)力矩,其消(xiao)耗的(de)電(dian)機(ji)(ji)功(gong)率占配套(tao)電(dian)機(ji)(ji)功(gong)率的(de)7%~12%左(zuo)右(you),功(gong)率消(xiao)耗大(da)。20世(shi)紀90年代(dai)初,遼寧北票市理想機(ji)(ji)械(xie)有限(xian)公(gong)(gong)司(si)董事(shi)長李憲(xian)章同志帶領本公(gong)(gong)司(si)技術人員著(zhu)手研究采用(yong)滾(gun)動(dong)(dong)軸(zhou)承代(dai)替老式磨(mo)(mo)機(ji)(ji)滑(hua)(hua)動(dong)(dong)軸(zhou)承。
