球磨機磨礦介質的運動狀態與筒體轉速及介質數量的關系?磨礦介質的運動狀態與筒體的轉速和介質數量有關,其次與筒體襯板的型式有關。研究表明,陶瓷球磨機內(nei)的鋼球(qiu)(qiu)隨(sui)(sui)轉(zhuan)度(du)的不(bu)(bu)同出現的三(san)種運(yun)動(dong)狀(zhuang)(zhuang)(zhuang)態(tai)是對一定(ding)(ding)(ding)鋼球(qiu)(qiu)填(tian)充率而(er)言的,當(dang)磨(mo)(mo)機內(nei)只(zhi)有少數球(qiu)(qiu)時(shi),球(qiu)(qiu)只(zhi)在筒(tong)(tong)體(ti)較低位(wei)置處跳動(dong),根本不(bu)(bu)隨(sui)(sui)筒(tong)(tong)壁上升,只(zhi)有當(dang)球(qiu)(qiu)荷(he)充填(tian)率達到一定(ding)(ding)(ding)程度(du)時(shi),才出現隨(sui)(sui)筒(tong)(tong)壁上升和(he)(he)拋落現象。此(ci)(ci)外,研究發現,磨(mo)(mo)礦機內(nei)鋼球(qiu)(qiu)充填(tian)率為(wei)10%、20%、30%時(shi),若不(bu)(bu)加水(shui)和(he)(he)礦砂(sha),鋼球(qiu)(qiu)還(huan)產生滑動(dong);只(zhi)有充填(tian)率達到40%時(shi),鋼球(qiu)(qiu)滑動(dong)停止。由(you)于磨(mo)(mo)機內(nei)鋼球(qiu)(qiu)的運(yun)動(dong)狀(zhuang)(zhuang)(zhuang)態(tai)與(yu)筒(tong)(tong)體(ti)轉(zhuan)度(du)和(he)(he)填(tian)充率有關,因(yin)此(ci)(ci),在一定(ding)(ding)(ding)轉(zhuan)速下(xia)(xia)不(bu)(bu)同充填(tian)率鋼球(qiu)(qiu)的運(yun)動(dong)狀(zhuang)(zhuang)(zhuang)態(tai)不(bu)(bu)同;而(er)在一定(ding)(ding)(ding)充填(tian)率下(xia)(xia),不(bu)(bu)同轉(zhuan)速的球(qiu)(qiu)荷(he)運(yun)動(dong)狀(zhuang)(zhuang)(zhuang)態(tai)也(ye)不(bu)(bu)同。襯(chen)板的形狀(zhuang)(zhuang)(zhuang)及礦漿濃度(du),主要影響球(qiu)(qiu)荷(he)與(yu)襯(chen)板及球(qiu)(qiu)之間的摩(mo)擦(ca)狀(zhuang)(zhuang)(zhuang)態(tai),因(yin)此(ci)(ci),也(ye)影響球(qiu)(qiu)荷(he)的運(yun)動(dong)狀(zhuang)(zhuang)(zhuang)態(tai)。
