球磨(mo)機亦(yi)為(wei)單倉磨(mo)，由給料、進料、軸承、筒體、出(chu)料、傳(chuan)動、減速、電動機等(deng)組成。
給(gei)(gei)料(liao)——球磨機給(gei)(gei)料(liao)是(shi)傾斜式溜槽(cao)送料(liao)，其(qi)仰角要大于(yu)所磨物(wu)料(liao)的(de)(de)靜摩擦角。斜溜槽(cao)斷面下半部以半圓形為好，方形也(ye)能使(shi)用(yong)。給(gei)(gei)料(liao)溜榴和進(jin)(jin)(jin)料(liao)部聯接處有密(mi)封(feng)裝置，般使(shi)用(yong)密(mi)封(feng)填料(liao)（石(shi)棉繩、石(shi)墨填料(liao)）將聯接處密(mi)閉。其(qi)作用(yong)是(shi)防止進(jin)(jin)(jin)料(liao)時，物(wu)料(liao)由于(yu)下料(liao)后在進(jin)(jin)(jin)料(liao)部堆積而往外倒料(liao)。也(ye)有在進(jin)(jin)(jin)料(liao)部軸頸空(kong)心(xin)處裝上螺旋進(jin)(jin)(jin)料(liao)器或勺式給(gei)(gei)料(liao)器，將給(gei)(gei)料(liao)部內的(de)(de)物(wu)料(liao)和液體挖入進(jin)(jin)(jin)料(liao)部。
進(jin)(jin)料(liao)——為(wei)了更好地輸送物料(liao)，進(jin)(jin)料(liao)端空心(xin)軸內裝有(you)鑄錒(a)村套。襯套上鑄有(you)螺(luo)旋推(tui)進(jin)(jin)線(xian)，螺(luo)旋線(xian)是(shi)左旋還是(shi)右旋要根據磨(mo)機轉(zhuan)動方向(xiang)而(er)定(ding)，但(dan)須(xu)使(shi)物料(liao)能通過(guo)螺(luo)旋推(tui)入磨(mo)機筒體(ti)。
軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)——前后主軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)為空心(xin)軸(zhou)，是(shi)由(you)半(ban)圓(yuan)型(xing)滑動軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)所支承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)，即軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)下(xia)部(bu)有半(ban)圓(yuan)形的軸(zhou)瓦，軸(zhou)襯材料(liao)(liao)為軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)合(he)金。軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)座上部(bu)有油(you)(you)管向(xiang)軸(zhou)上噴淋潤滑油(you)(you)以起潤滑和冷卻作(zuo)用。軸(zhou)承(cheng)(cheng)(cheng)(cheng)(cheng)(cheng)底座在球磨(mo)機(ji)進料(liao)(liao)端可以沿軸(zhou)向(xiang)滑動，用以解(jie)決磨(mo)機(ji)工(gong)作(zuo)時(shi)溫度上升導(dao)致(zhi)磨(mo)機(ji)筒體受熱膨(peng)脹(zhang)問題。它可以避免由(you)于(yu)限(xian)制膨(peng)脹(zhang)伸(shen)長而(er)產生(sheng)的軸(zhou)向(xiang)溫度膨(peng)脹(zhang)應力。
筒體(ti)(ti)(ti)——筒體(ti)(ti)(ti)是用普通(tong)Q235A鋼(gang)板卷(juan)制而成。簡體(ti)(ti)(ti)兩端(duan)(duan)(duan)有(you)大法蘭和鑄鋼(gang)制的(de)(de)磨端(duan)(duan)(duan)蓋連接。筒體(ti)(ti)(ti)的(de)(de)出(chu)料端(duan)(duan)(duan)即在(zai)出(chu)料處的(de)(de)端(duan)(duan)(duan)蓋和筒體(ti)(ti)(ti)連接處有(you)篩(shai)板以阻止鋼(gang)球(qiu)和鋼(gang)段流出(chu)出(chu)料端(duan)(duan)(duan)。筒體(ti)(ti)(ti)內(nei)裝有(you)一(yi)定(ding)重(zhong)量、按一(yi)定(ding)比例配比直徑為(wei)25 -150mm的(de)(de)鋼(gang)球(qiu)或鋼(gang)段作為(wei)研磨體(ti)(ti)(ti)。
筒體(ti)內襯(chen)(chen)(chen)有一(yi)定形狀(zhuang)和材(cai)質(zhi)的(de)襯(chen)(chen)(chen)板(ban)(ban)(ban)(ban)(ban)，不僅可以防止簡體(ti)遭受(shou)磨(mo)損，而且襯(chen)(chen)(chen)板(ban)(ban)(ban)(ban)(ban)的(de)形狀(zhuang)影響鋼球的(de)運動規律，從(cong)而影響粉磨(mo)效率。襯(chen)(chen)(chen)板(ban)(ban)(ban)(ban)(ban)材(cai)質(zhi)有高錳鋼、高鉻鑄鐵(tie)、中錳球鐵(tie)和橡膠(jiao)(jiao)等，襯(chen)(chen)(chen)板(ban)(ban)(ban)(ban)(ban)的(de)厚度(du)通常為50～130一(yi)。襯(chen)(chen)(chen)板(ban)(ban)(ban)(ban)(ban)和筒體(ti)之間墊(dian)有膠(jiao)(jiao)合板(ban)(ban)(ban)(ban)(ban)、橡皮墊(dian)、石棉橡膠(jiao)(jiao)墊(dian)等。襯(chen)(chen)(chen)板(ban)(ban)(ban)(ban)(ban)一(yi)般用螺(luo)(luo)栓固定在簡體(ti)上，螺(luo)(luo)帽下面(mian)有橡膠(jiao)(jiao)圈(quan)和金屬墊(dian)圈(quan)，防止料漿(jiang)漏出。
筒體上有人孔，停機后打開密閉(bi)的(de)人孔蓋，可以進(jin)去更(geng)換襯(chen)(chen)(chen)板、隔(ge)板、篩板或補充(chong)鋼(gang)(gang)(gang)球(qiu)鋼(gang)(gang)(gang)段。常(chang)用襯(chen)(chen)(chen)板的(de)形狀(zhuang)見圖1-26，形狀(zhuang)較平滑(hua)的(de)襯(chen)(chen)(chen)板使(shi)鋼(gang)(gang)(gang)球(qiu)同襯(chen)(chen)(chen)板之(zhi)間的(de)相對滑(hua)動較大．產生較多(duo)的(de)研(yan)磨作(zuo)用，在(zai)相同轉速下鋼(gang)(gang)(gang)球(qiu)被(bei)提升的(de)高度和拋(pao)射所耗的(de)功較步，適于細(xi)磨。凸起部較高的(de)襯(chen)(chen)(chen)板對鋼(gang)(gang)(gang)球(qiu)的(de)推舉作(zuo)用強，使(shi)鋼(gang)(gang)(gang)球(qiu)能升至(zhi)較高的(de)位置(zhi)，沖擊作(zuo)用較強。橡(xiang)膠村板耐(nai)磨損（壽命比(bi)錳(meng)(meng)鋼(gang)(gang)(gang)襯(chen)(chen)(chen)板高2～3倍）、重(zhong)量輕(qing)（比(bi)錳(meng)(meng)鋼(gang)(gang)(gang)村板輕(qing)約85%）、拆裝方便、噪聲小。
出(chu)(chu)料——空心軸出(chu)(chu)料端內裝有一個(ge)斜(xie)截(jie)頭圓錐形鑄鋼襯套，襯套上鑄有螺(luo)旋(xuan)葉片，襯套外裝有一固(gu)定(ding)不轉(zhuan)動的篩(shai)網(wang)(wang)。料或料漿從村套中流(liu)出(chu)(chu)經過篩(shai)網(wang)(wang)篩(shai)出(chu)(chu)磨小的鋼球(qiu)、鋼段后流(liu)出(chu)(chu)磨機(ji)外。
傳(chuan)(chuan)動(dong)(dong)——單倉磨(mo)機一(yi)般是(shi)邊緣(yuan)傳(chuan)(chuan)動(dong)(dong)，現(xian)亦有(you)中心傳(chuan)(chuan)動(dong)(dong)的。在筒(tong)(tong)體出(chu)料(liao)端和(he)端蓋連接(jie)處有(you)大齒(chi)(chi)圈。電動(dong)(dong)機通過(guo)聯軸器(qi)(qi)及減速(su)(su)器(qi)(qi)與高速(su)(su)軸聯接(jie)，也有(you)用同步電機通過(guo)齒(chi)(chi)輪聯軸器(qi)(qi)帶(dai)動(dong)(dong)小齒(chi)(chi)輪傳(chuan)(chuan)動(dong)(dong)筒(tong)(tong)體大齒(chi)(chi)圈的。減速(su)(su)器(qi)(qi)低速(su)(su)軸處也是(shi)通過(guo)聯軸器(qi)(qi)和(he)小齒(chi)(chi)輪聯接(jie)，帶(dai)動(dong)(dong)小齒(chi)(chi)輪轉動(dong)(dong)促使大齒(chi)(chi)圈和(he)小齒(chi)(chi)輪嚙合(he)傳(chuan)(chuan)動(dong)(dong)回(hui)轉而將筒(tong)(tong)體回(hui)轉起來。邊緣(yuan)傳(chuan)(chuan)動(dong)(dong)可以根據地點，安(an)裝需要制(zhi)成右傳(chuan)(chuan)動(dong)(dong)、左傳(chuan)(chuan)動(dong)(dong)兩種。
