The mill is of fringe transmission, central unloading, and open style.

主要由圆柱形筒体、进、出料装置、中空轴、主轴承、传动小齿轮、大齿圈、减速机、电动机等部件组成。
It consists of cylinder body, material input and output device, hollow shaft, main bearing, transmission pinion, big gear ring, reducer,motor etc.

回转部分（筒体）Rotating part(cylinder)

回转部分是由钢板卷制焊接而成的筒体，两端用螺栓分别与进、出料、中空轴相连接，并水平地支撑在两个调心轴承上。进出料中筒内装有进出料螺旋。
The rotating part is the cylinder made of welded steel plate, the two ends are connected by screws with the material input & output device, and hollow shaft. They are supported by the central adjustment bearing horizontally. The material input & output device has the screws inside.

筒体的回转由电动机、减速机、小齿轮、通过固定在筒体一端的大齿圈来实现的。
The cylinder rotation is made by the motor, reducer and pinion through the fixed gear ring on the cylinder end.

筒体的内部设有衬板，它既可以保护筒体，又可以把球带到适宜的高度，以提高粉磨效率。
The liner inside the cylinder can protect the cylinder but also carry the balls to the proper height, to improve the grinding efficiency.

筒体上设有人孔门，用于装卸磨体、修理更换筒体内部的零件之用。
The manhole on the cylinder is used to load & unload the material and to repace the part inside the cylinder.

进、出料装置/Material input & output device

进料装置主要用于进料和添加钢球；出料装置用于输出成品物料及磨损的钢球、硬物等。
The material input device are mainly used for feeding material and steel ball, while the output device are for the output of finished material,worn steel ball and hard substance etc.
支撑装置/Supporting device
主轴承支撑着回转部分、磨球、物料等全部质量，是保证磨机正常运转的主要部件之一。主轴承能自动调心，以适应制造、安装的误差。
The main bearing support the total weight of the rotating part, ball and material inside, which is one of the main parts to ensure the normal operation of the mill. It can make adjustment for the central line to adapt the tolerance in manufacturing and installation.
传动装置/Transmission device
由电动机通过弹性联轴器、减速机、小齿轮、大齿圈形成传动链。
It is a transmission chain by motor through the elastic coupling, reducer,pinion and gear ring.
特别提示：球磨机传动装置的布置，不允许随意变动，。如需变动，必须要保证小齿轮对大齿轮的作用力垂直向上，并由此决定球磨机的回转方向，同时必须改变所有带方向性的零、部件结构。通常情况下，这是不允许的。
Note: The transmission device's layout of ball bill must not be changed casually. If needed, it must ensure the action between gear and pinion is vertical & straight up, by which the rotating direction of ball mill is decided. Meanwhile we must change all the parts'structure with direction. Usually, it is not allowed.

2、工作原理：/ Working principle
当电动机通过联轴器、减速机、小齿轮、大齿圈带动筒体旋转，装在筒体内的破碎介质（钢球）与不断进入筒体内的物料在离心力和摩擦力的作用下，随着筒体上升到一定高度，然后脱离筒壁自由落下。物料的破碎主要是靠介质落下时的冲击力和运动时的磨剥作用来实现。物料是从进料段的中空轴内不断地输入，而磨碎以后的产品经筒体的另一端的中空轴不断排出。湿磨时，成品被水的流动而带走。
The cylinder get rotated by motor through coupling, reducer,pinion, and gear. The grinding media(steel ball) and continuously feeded material inside the mill will go up to a certain height with the cylinder under the centrifugal and friction force, then dropping down freely off the cylinder. The material crushing is realized mainly by the impact force of the dropping media and grating &shucking function during moving. The material is fed in gradually from the hollow shaft of input end, and the grated ones are discharged through the other end of the hollow shaft consistently, which will be carried away by water in wet ball mill.

球磨机分左、右旋磨矿。客户可根据自己的现场决定，需要在采购合同中注明。
The ball mill can be divided into left direction rotation mill and right one. It need to be noted in the contract according to the customer's plant.

五、 试车、使用和维修保养/
Test, operation, and maintenance

(一) 球磨机安装完毕并符合安装要求后，才能进行试车运转工作，试运转程序如下：
Test running for ball mill can be made after the installation is finished, complying with the installation requirements. The procedure for test running are as follows:
1) 将减速机内按要求加注润滑油，齿轮护罩内加入齿轮油；
Lubricant should be added to reducer, and gear oil into gear cover.
2) 球磨机空运转24小时（不加研磨体）；
Keep ball mill running for 24 hours without grinding media.
3) 加入1/3研磨体并喂料，运转8小时
Get ball mill running for 8 hours with 1/3 grinding media and raw materials inputing.
4) 加入2/3研磨体并喂料，运转72小时；
Get ball mill running for 72 hours with 2/3 grinding media and raw materials inputing.

设备试运转过程中，要注意转动部位的温度，主轴承、传动轴承的温度不得超过70℃。减速机在试运转期间应密切注意个润滑点的供油情况是否正常，电动机的负荷、大、小齿轮及减速机声音是否有异常等。每次试运转中的震动情况应严格注意。停机后，要检查轴颈与轴承的情况、传动齿轮的啮合情况、检查地脚螺栓、中空轴螺栓、衬板紧固螺栓、大齿圈螺栓等紧固情况，检查各处有无漏料等情况。
During the test running of ball mill, please note that the temperature of rotary part, main bearing and transmisson bearing can not surpass 70℃ . It should be noticed closely for each lubricating point on reducer to confirm if the oil supply is normal or not; if it is normal for the motor load, the sound of gear and pinion and reducer. The vibration of test running should be noted strictly. When the mill is stopped, it should be checked for the situation of the bearing neck and the bearing, transmission junction, the screw fixing on anchor, hollow shaft and liner fixed one, and gear etc.and the leakage per place.

（二）试运转合格后，允许正式使用，用户可根据具体情况，制订操作、维护、检修制度，以保证设备的正常运转。
After test running is qualified, the ball mill is allowed to run officially, customers can make the principle for operation ,maintenance, and inspection according to their own situations to ensure the normal running of the equipment.

（1）球磨机操作的知识 Operation method for ball mill
判断球磨机运转是否正常有两种常用的办法：第一种办法是检查物料的出料粒度，若合乎要求，且跳动不大，就说明球磨机的运转正常，说明加料恰当、物料的进料粒度、水分都合适，球级配合适。第二种办法是听球磨机的声音，设备运转正常时应该是“哗哗”夹杂着轻微的冲击声。如果声音变的暗哑，发出“轰轰”的声音，冲击声听不到，说明仓内物料过多，严重时出现满磨现象，这时应立即停止喂料，待设备正常运转后在继续喂料；如停止喂料后，正常的声音仍然听不到，物料很难喂入，而且出料很少，对于干式球磨机说明筒体内有严重粘磨现象，应立即进行处理，一般来说可用以下办法解决：若是入磨物料水分过高，则应降低入磨物料水分在2%以内，也可以加入部分干物料，研磨能消除上述现象，湿式球磨机不会出现此现象。球的冲击声很强，说明筒体内物料少，应增加喂料，喂料量不可过强，应逐步的调整过来。
There are two ways to judge whether ball mill works smoothly or not. The first way is to check the output size of materials. If it is close to the requirement with little tolerance, that means the ball mill is running smoothly with proper input material, the size, the moisture and the ball grade. The second way is to listen to the sound, the normal operation should have the slighter impacting sound with 'haha'. if it get lower, with'honghong', and no impacting sound, it means that the material inside is too much, and maybe of the whole mill so that we must stop feeding in immediately until it is normal operation. If stop feeding in material, the normal sound is still not available, and the material is hard to feed in, with little material output. It shows that there are serious mill sticking situation for dry type ball mill and must be handled at once. Usually the following method is used: if the moisture of the material input is too high, then it should be reduced by 2% or less or adding into some dry material for grinding to rid of that situation. The wet type ball mill has no such situation. If the ball has strong impact sound, it shows that the material is less, and we should increase the material feeding in, which should not be too much and get adjusted gradually.
