1. 磨機(jī)工作原理及用途PRINCIPLE OF OPERATION AND USES OF MILL

管磨機(jī)是水平的回轉(zhuǎn)圓筒，內(nèi)裝研磨體（一般為鋼球、鋼鍛）。主要靠筒本回轉(zhuǎn)時(shí)將研磨體升舉落下的沖擊能量將物料磨碎。在工作過程中，反復(fù)進(jìn)行的沖擊粉碎和滾動(dòng)、滑動(dòng)研磨，使塊狀物料逐漸變小，成為細(xì)粉。本機(jī)主要用于水泥生料及水泥熟料的粉磨。
Tube Mill is a horizontal rotary cylinder, load in abrasive mediums (general they are steel grinding balls, cylpebs). To crush the materials mainly by percussion energy of the abrasive bodies when the shell rotary to lift and fall them. And the material to be crushed. During the operational progress, by roll and slide repeatedly crushing. So massive material become powder.
This machine is mainly used in grinding for cement raw meals and cement clinkers.
2.結(jié)構(gòu)概述SUMMARY  FOR  STRUCTURE
  2.1傳動(dòng)系統(tǒng)Transmission system
  傳動(dòng)系統(tǒng)包括電動(dòng)機(jī)、減速器、傳動(dòng)軸、大小齒輪(中心傳動(dòng)無大小齒輪)和聯(lián)軸器等。電動(dòng)機(jī)與減速機(jī)之間、減速器與小齒輪之間以彈性聯(lián)軸器聯(lián)接。此種聯(lián)軸器吸震性好，可以減少磨機(jī)沖擊震動(dòng)對減速器的影響，可以提高設(shè)備使用壽命，且維修十分方便。大齒輪固定在筒體上。由電動(dòng)機(jī)通過減速器、傳動(dòng)軸、小齒輪、大齒圈帶動(dòng)筒體回轉(zhuǎn)。為了增加傳動(dòng)齒輪的使用壽命。磨機(jī)采用“大變位”齒輪。
  Transmission system is comprises of motor, reduction unit. Transmission shaft. Girth gear and pinion(central drive mill don’t use girth gear and pinion), coupling, etc. The reduction unit is connected to the motor by spring coupling, and the pinion is connected to the reduction unit by spring coupling which has a good damping capacity and may reduce the shock and vibration influence of mill shell on the reduction unit and increase the service life of the equipment and convenient to maintain. Girth gear is fixed on the flange of shell body, shell body is rotated by motor passing reducer transmission shaft pinion shaft pinion and girth grar rim. Inorder to increase service lift of transmission gears. The mill uses the “l(fā)arge modified” gear.
2.2進(jìn)料裝置Feed device
   進(jìn)料裝置主要包括進(jìn)料斗支架、觀察門、進(jìn)料斗等。進(jìn)料斗內(nèi)裝有襯板，同時(shí)利用物料本身作襯墊以減少物料對進(jìn)料斗的磨損。進(jìn)料斗與支架間有墊片，用增減墊片的方法來調(diào)節(jié)中心高度。
Feed device mainly consists of charging hopper supports, observation door.etc.liner is fixed in the charging hopper.But it also uses materials as liner to reduce its wearing for charging hopper. The spacers are used between the hopper and the supper by increasing or decreasing the spacer pieces.
2.3回轉(zhuǎn)部分Rotating part
回轉(zhuǎn)部分是由進(jìn)出料螺旋筒、進(jìn)出料中空軸、大齒輪（中心傳動(dòng)無大齒輪）、筒體、襯板及隔倉板等部件組成。
筒體用鋼板卷制焊接而成，筒體兩端焊有同類鋼板的平端蓋。筒體上開有人孔，人孔用相同材料的加強(qiáng)板加強(qiáng)。磨體內(nèi)分為粗磨倉、細(xì)磨倉。在粗磨倉中裝有ZGMn13（鑄造錳鋼）襯板用螺栓將其聯(lián)接在筒體上。為了減輕應(yīng)力集中，襯板的螺栓孔采用橢圓形。細(xì)磨倉中亦有用螺栓固定的或鑲嵌的襯板，隔倉板為單層隔倉板，材質(zhì)為ZGMn13（鑄造錳鋼）。整個(gè)回轉(zhuǎn)部分依靠兩個(gè)中空軸支承在兩個(gè)主軸承上。中空軸與平端蓋之間用螺栓聯(lián)接。
Rotating part has charging and discharging screw. Charging and discharging Trunnion shafts, girth gear, (central drive hasn’t girth gear)shell body,liners and compartment separators,etc.
Shell body is made of steel plates which are rolled up and welded .The plain-end covers of the same kind of steel plates are welded on the shell body ends. There are manholes on shell body with each one has a strengthen edge. The mill has a coarse grinding compartment and a fine grinding compartment. The circular liners of ZGMn13 manganese casting steel are bolted on the shell body in the coarse grinding compartment. The shape of boltholes is oval to prevent the stress concentration. Liners are uses in the fine grinding compartment by bolt . The compartment separators of ZGMn13 manganese casting steel are single layer. The two main bearings support the whole rotating part by two quill shafts. Quill shafts are connected with plain-end covers by bolts.
 2．4主軸承  Main bearing
主軸承由球面瓦、軸承座與上蓋等主要零部件組成。為保證中空軸軸線保持在一個(gè)軸線上，采用球面體的軸承瓦，以保證自動(dòng)調(diào)心和主軸承正常油潤滑。
在中空軸上裝有固定油圈（即“帶油圈”），由固定油圈帶油潤滑。為了防止漏油，主軸承兩端裝小油刷，在靠近筒體一側(cè)裝有刮油板。（根據(jù)用戶亦可用稀油站潤滑）
為保證主軸承在正常溫度下進(jìn)行工作，在主軸承和球面瓦之間通以冷卻水進(jìn)行冷卻。由于粉磨產(chǎn)生大熱量傳出影響主軸承正常工作，在螺旋筒和中空軸之間的縫隙中填以隔熱材料。
Main bearings are comprised of globe bearings, bearing seats and upper covers, etc. The globe bearings are used for purposes of automatic alignment shaft lines of trunnion shafts each other, and make regular oil lubrication for main bearings.
The fixed oil rings (belt oil rings)are installed on the trunnion shafts for lubrication . To prevent oil leakage small oil brushes are installed on the both sides of main bearing and oil scrapers are installed on the side of near shell body. (thin oil station is used according to custom’s requirement)
Because the grinding produces a large amount of heat. The main bearings are cooled by water to keep the normal operation of the main bearings. Heat-insulating material is filled into the gap between the screw tube and trunnion shaft to prevent heat transfer.
