(l)按長(chang)(chang)(chang)徑(jing)比分：長(chang)(chang)(chang)徑(jing)比即磨(mo)(mo)機(ji)簡(jian)體長(chang)(chang)(chang)度和簡(jian)體直徑(jing)的比例。長(chang)(chang)(chang)徑(jing)比在2以(yi)下(xia)是(shi)短(duan)磨(mo)(mo)機(ji)，亦稱球(qiu)磨(mo)(mo)機(ji)，般(ban)(ban)為(wei)(wei)單(dan)倉，用(yong)于(yu)粗磨(mo)(mo)，多臺球(qiu)磨(mo)(mo)機(ji)串聯可作(zuo)為(wei)(wei)一級磨(mo)(mo)使用(yong)。長(chang)(chang)(chang)徑(jing)比2～3時為(wei)(wei)中(zhong)長(chang)(chang)(chang)磨(mo)(mo)機(ji)。長(chang)(chang)(chang)徑(jing)比在4以(yi)上為(wei)(wei)長(chang)(chang)(chang)磨(mo)(mo)機(ji)亦稱管磨(mo)(mo)機(ji)，其(qi)內(nei)部一般(ban)(ban)分為(wei)(wei)2～4個倉。
(2)按(an)研磨(mo)體形(xing)狀分．球(qiu)磨(mo)機(ji)內裝填研磨(mo)體為鋼(gang)球(qiu)或(huo)鋼(gang)段(duan)。棒(bang)(bang)球(qiu)磨(mo)機(ji)一(yi)般為管磨(mo)機(ji)，一(yi)倉裝有(you)圓柱形(xing)鋼(gang)棒(bang)(bang)，以后各倉裝鋼(gang)球(qiu)或(huo)鋼(gang)段(duan)，棒(bang)(bang)長(chang)較(jiao)棒(bang)(bang)倉長(chang)度應短1。0 mm左(zuo)右為宜，以利于(yu)鋼(gang)棒(bang)(bang)平行排列，防(fang)止交(jiao)叉，棒(bang)(bang)磨(mo)機(ji)主要用于(yu)濕法磨(mo)。 ;
(3)按(an)排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)方(fang)式分(fen)：按(an)排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)方(fang)式可分(fen)為溢流排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)、格(ge)子排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)、周邊(bian)排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)和簡體中部周邊(bian)排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)。主(zhu)要的排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)方(fang)式是溢流排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)和格(ge)子排(pai)(pai)(pai)料(liao)(liao)(liao)(liao)(liao)兩種。
球磨(mo)(mo)機(ji)運(yun)轉時，物料(liao)給(gei)入筒體(ti)后(hou)即堆積于簡體(ti)左端，由于簡體(ti)的轉動和研磨(mo)(mo)體(ti)的運(yun)動，物料(liao)逐漸(jian)向右端擴散，后(hou)從(cong)右端的中空(kong)軸溢流而出，故稱作溢流型球磨(mo)(mo)機(ji)。
另一種(zhong)球磨機是在(zai)出(chu)料(liao)(liao)端附近有格子板(ban)(ban)(ban)。格子板(ban)(ban)(ban)由若干塊(kuai)(kuai)扇形板(ban)(ban)(ban)組成，扇形板(ban)(ban)(ban)上有寬度(du)8～20mm的篩(shai)孔(kong)，物(wu)料(liao)(liao)可通過篩(shai)孔(kong)而聚集在(zai)格子板(ban)(ban)(ban)與右端蓋(gai)之間(jian)的空(kong)(kong)間(jian)內(nei)。此空(kong)(kong)間(jian)內(nei)有若干塊(kuai)(kuai)輻(fu)射(she)狀的舉(ju)板(ban)(ban)(ban)。簡體轉(zhuan)動時，舉(ju)板(ban)(ban)(ban)將物(wu)料(liao)(liao)向(xiang)上提(ti)舉(ju)，物(wu)料(liao)(liao)下落時經(jing)過錐形塊(kuai)(kuai)而向(xiang)出(chu)料(liao)(liao)端折轉(zhuan)，經(jing)右端中空(kong)(kong)軸(zhou)排出(chu)。由于格子板(ban)(ban)(ban)和舉(ju)板(ban)(ban)(ban)的作用(yong)，物(wu)料(liao)(liao)在(zai)出(chu)料(liao)(liao)端的料(liao)(liao)位較(jiao)低，使排料(liao)(liao)加快(kuai)，生產(chan)量(liang)提(ti)高，參見圖(tu)1-25。
(4)按(an)傳動(dong)(dong)(dong)方式(shi)分中心傳動(dong)(dong)(dong)是電(dian)動(dong)(dong)(dong)機通(tong)過減(jian)(jian)速器(qi)帶動(dong)(dong)(dong)磨(mo)機卸(xie)料端空心軸(zhou)而驅(qu)動(dong)(dong)(dong)簡體回(hui)轉 減(jian)(jian)速器(qi)的(de)出軸(zhou)和(he)磨(mo)機的(de)中心線為同軸(zhou)線。邊緣轉動(dong)(dong)(dong)是電(dian)動(dong)(dong)(dong)機通(tong)過減(jian)(jian)速器(qi)帶動(dong)(dong)(dong)固(gu)定在卸(xie)料端筒(tong)體上的(de)大(da)齒(chi)輪而驅(qu)動(dong)(dong)(dong)簡體回(hui)轉。其他按(an)操作工(gong)藝分有干(gan)法、濕法、煤磨(mo)、帶烘干(gan)倉(cang)式(shi)、風(feng)掃式(shi)等等。
