1. 磨機工作原理及用途PRINCIPLE OF OPERATION AND USES OF MILL

      管磨機是水平的回轉圓筒，內裝研磨體（一般為鋼球、鋼鍛）。主要靠筒本回轉時將研磨體升舉落下的沖擊能量將物料磨碎。在工作過程中，反復進行的沖擊粉碎和滾動、滑動研磨，使塊狀物料逐漸變小，成為細粉。本機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.結構概述SUMMARY  FOR  STRUCTURE
  2.1傳動系統Transmission system
  傳動系統包括電動機、減速器、傳動軸、大小齒輪(中心傳動無大小齒輪)和聯軸器等。電動機與減速機之間、減速器與小齒輪之間以彈性聯軸器聯接。此種聯軸器吸震性好，可以減少磨機沖擊震動對減速器的影響，可以提高設備使用壽命，且維修十分方便。大齒輪固定在筒體上。由電動機通過減速器、傳動軸、小齒輪、大齒圈帶動筒體回轉。為了增加傳動齒輪的使用壽命。磨機采用“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 “large modified” gear.
2.2進料裝置Feed device
   進料裝置主要包括進料斗支架、觀察門、進料斗等。進料斗內裝有襯板，同時利用物料本身作襯墊以減少物料對進料斗的磨損。進料斗與支架間有墊片，用增減墊片的方法來調節中心高度。
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回轉部分Rotating part
回轉部分是由進出料螺旋筒、進出料中空軸、大齒輪（中心傳動無大齒輪）、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板加強。磨體內分為粗磨倉、細磨倉。在粗磨倉中裝有ZGMn13（鑄造錳鋼）襯板用螺栓將其聯接在筒體上。為了減輕應力集中，襯板的螺栓孔采用橢圓形。細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，材質為ZGMn13（鑄造錳鋼）。整個回轉部分依靠兩個中空軸支承在兩個主軸承上。中空軸與平端蓋之間用螺栓聯接。
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軸線上，采用球面體的軸承瓦，以保證自動調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，在靠近筒體一側裝有刮油板。（根據用戶亦可用稀油站潤滑）
為保證主軸承在正常溫度下進行工作，在主軸承和球面瓦之間通以冷卻水進行冷卻。由于粉磨產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.
2.5出料裝置 Discharging device
出料裝置是由出料罩、支架、出料篩子等零件組成。出料篩是用螺栓和出料螺旋筒聯接在一起的。經粉磨后的物料經過篩選后落入出料罩，其中雜質（如鐵塊、螺栓等）則從排渣口自動排出。在出料罩上部裝有管道收塵器聯接，為防止漏風，下部應裝鎖風裝置，再與輸送設備連接，否則會影響磨機的粉磨和產量。
Discharging device consists of discharging cover、 supports、discharging screen, etc. The discharging screen is connected with discharging screw tube by bolts. The ground material drops into discharging cover through the screen. Some objects (such as iron pieces,bolts,etc.) will be removed from exit. The pipeline connected with dust collector is installed on the discharging cover. Air lock device is installed on the lower part of discharging cover which is connected with conveying equipment in order to avoid air leak.

1. 已變質的或不干凈的油禁止使用.冬季加油或換油時,應預先將油加熱至20℃左右.

The deteriorated or soiled oil is forbidden to be used, when oil is added or replaced in winter season, the oil should be pre-heated to about 20℃.

1. 經常檢查各軸承溫度不得超過60℃,檢查潤滑點的油位高度和潤滑油系統供油壓力和供油量,主軸承溫度控制在15～60℃.若低于15℃應將主軸承冷卻水減少或暫時關閉.

The temperature of every bearing must not exceed 60℃. The oil level height of lubuication site, oil charging pressure and oil quamtity charge of the lubricating system should be checked regularly. The temperature of main bearing should be  controued between 15℃ and 60℃. If the temperature is lower than 15℃, the cooling water should be reduced or turned off temporarily.

1. 新裝襯板的螺栓,在開始數日運轉中常發生松動,因此須隔一定時間檢查并擰緊,并注意檢查襯板螺栓有無斷裂.

The bolts of newly installing linere happen loose frequently in first few days, so should be reduced or turned off temporarily.

1. 要注意檢查并記錄電動機電流值的變化.若電流下降(這說明磨內研磨體和襯板磨損過多),應及時調整,更換研磨和襯板.

Variations of the motor current should be checked and recorded. If the current has dropped (this reflects the wear of grinding media and liners), the grinding media and liners should be adjusted and replaced without delay.

1. 除日常維護外,要定期檢查主軸承,中空軸,筒體,減速器,大小齒輪,襯板的磨損情況并做好記錄,發現問題及時處理,做好檢修計劃.

Besides ordinary maintenance, wear condition of main bearings, trunnion shafts, mill shell. Decelerator, girth gear and pinion and liners should be checked and recprded at regular intervals. Treatment and overhaul should be given when troubles happen to the mill.
4.2.2 注意事項:  Points for attention:

(4)長期停磨時應把研磨體倒出,以免筒體變形.
If the mill stop working for a long period of time. The grinding media should be discharged to prevent the mill shell deforming.
(5)在冬季,生產時要注意磨尾氣保溫工作,若溫度低于露點,會出現冷卻水,損壞收塵器.
In winter season. Hat preserving of cxhausting gases on the mill tail should be treated in operation. If the temperature is lower than dew-point. Condensating water will appear and damage the dust collector.
(6)在冬季(我國北方),停磨8小時以上,在開動磨機前應將主軸承潤滑油放出,加熱至20℃,再倒入主軸承內.
In winter season (in the northern part of our country). After machine halt for more than 8 hours, the lubrication oil should be poured out and heated up to 20℃, then poured into main bearing before mill starting.
4.3檢修Overhaul
