试验室XMB240×300型球（棒）磨机技术参数
Technical Parameters of Laboratory Ball (rod) Mill

XMQ棒磨机适用于实验室湿法磨细矿石或其他物料之用。也可以将钢棒换为钢球作球磨机使用。但棒磨时，磨细产物粒度组成较均匀，过粉碎现象较小，且效率较高。一般进行矿石可选性实验研究和人工重砂磨细矿石时，宜采用棒磨。本产品由原地矿部唯一指定企业生产，执行行业标准。

XMB Rod Mill is applicable to lab. for wet fine grinding of ore and other materials. Steel ball may be used instead of steel rod in the ball mill. In rod grinding, fine product particle fractions are relatively uniform with rare occurrence of overgrinding and high efficiency. In general, rod grinding is introduced for test on ore for separability and manual fine grinding of placer materials. The product is produced by the only enterprise designated by the former Ministry of Geology and Mineral Resources, in compliance with the Industrial standards.

球墨铸铁筒体与大皮带轮用螺钉联为一体。筒体一端为开口，另一端为空心轴颈；两端分别承在一对托和一个主轴承上。主轴承座和托架，分别装在可转支180°的支承板上。支承板用两个轴承轴承座装在机架上。支承通过回转操纵手把及定位板，可以从水平左右偏转用22.5°、6735°、及90°，以完成装矿、排矿、倒棒和充满防锈石灰水等动作。

Drum of spheroidal graphite cast iron and big belt pulley are connected through screws. At one end of the drum is an opening and at the other end of it is a hollow journal. Both ends are respectively supported on a pair of rollers and a main bearing. The main bearing seat and bracket are respectively on the bearing plate which can rotate for 180°. The bearing plate is installed on the frame with two bearing pedestals. The bearings control the handle and positioning plate through rotation. Horizontal deflection of 22.5°, 6735° and 90°can be applied to realize ore loading, ore discharging, tamping rod, filling antirust limewater, etc.

筒体右端有给矿口塞。械端有排矿口盖；工作时，用一时专门板手，按顺时针方向拧紧螺栓，使排矿口盖上的密封橡胶垫紧螺栓三、四转使盖子向外退出工6～10毫米，不用将盖子取下即可排矿。在排矿口端安设了集浆罩。在设计工作转速内完全消除子转支清洗时矿浆飞溅的现象。

There is plug of feed mouth on the right of the drum and there is cover of discharge mouth at the end of the machine. During the operation of the machine, use a special-purpose spanner to tighten the bolts, to get the sealing rubber gasket on the cover of discharge mouth to tighten the bolts for three or four rounds so that the cover can go backward for 6～10mm. Ores can be discharged without the cover being removed. At the end of the discharging mouth is installed a slurry cover, which completely avoid splashing of slurry during the washing rotating branch within the designed working speed.

电机及中间轴装在支承下面，以便与上部的重量配置均衡。传动的两级皮带每级均可调节皮带松紧，以保证全适的磨矿工作转速。

The motor and intermediate shaft are installed below the bearings, so as to realize balance with the weight above. The tension of belt can be adjusted for every grade of the driving two-grade belt pulley, to ensure appropriate grilling speed.

67型棒磨机的皮带调整，是由支承板上T型槽滑道和中间轴座板上的长分别进行。

The pulleys of 67 rod mill are respectively adjusted through the T-groove slide on the supporting plate and the slot on the seat board of the intermediate shaft.

68型棒磨机的皮带调整，按下述方法进行：

The pulleys of 68 rod mill are respectively adjusted according to the following method:

1、筒体皮带的调整：主要是调节中间支承的上下位置。但为了不致景响电动机皮带的松紧，须对调整螺杆作相应的调整（图1）。

1. To adjust drum belt, what should be done mainly includes the adjustment of vertical position of intermediate support. However, in order not to affect the tension of motor belt, corresponding adjustment shall be made of the adjusting bolt (Figure 1).

S2 —调整螺杆调整量（图示向下）

S2 – Adjustment amount of adjusting bolt (moving downward as is shown in the figure)

2、电动机皮带的调整：主要是调节调整螺杆的上下，使中间轴绕中间支承转支一定位置。而为了不致影响筒体皮带的松紧。须对中间支轴承相应的调整，进行补偿。（图2）

2. To adjust motor belt, what should be done mainly includes the adjustment of vertical position of screw, to get the intermediate shaft to revolve around intermediate support to a certain position. However, in order not to affect the tension of drum belt, corresponding adjustment shall be made of the intermediate shaft for compensation (Figure 1).
