一、用途
I. Application
XMGQ功指數球磨機主要用于測定各種礦石、爐渣等物料的磨礦功指數。
XMGQ Work Index Ball Mill is mainly used to determine the work index of grinding of ores , slag and other materials.
二、工作原理
Ⅱ. Working Principle
與一般球磨機相同，將一定粒度和重量的物料放入球磨機內，球磨機內裝入一定尺寸、一定數量的鋼球，在特定轉數下進行干法磨礦，將產品篩分、稱重，反復進行多次，在經計算得出磨礦功指數（kwh/t）。
As with the common ball mill, materials of given size and weight and steel balls of certain size and number are put into ball mill. Dry grinding proceeds at the rated rotation speed to screen and weigh products repeatedly. The grinding work index（kwh/t）is obtained by calculation.

主機筒襯為整體波浪形，由沉頭螺釘固定在筒體一端開口用以進排料。棒磨機在磨礦過程中，如需傾翻角度時將轉動手把插銷提起，此時拉動定位插銷放進相應弧形槽內，轉動手把即可進行調整。
The liner plate for mill body is on the whole in the shape of wave. It is fixed at one end of the drum with sunk screws to feed and discharge materials. If a tilting angle is needed during the grinding process of the mill, lift the bolt of turning handle. At this time, pull the positing lock pin and put it into the corresponding arc groove. Turn the handle and adjustment can be made.
五.電氣部分及控制
V. Electrical Parts and Control
本機控制部分主要由數字顯示、自動計數、自動停機等電路組成。操作方法如下：
The control parts of this machine is composed of digital display, automatic counting, automatic shut-down and other circuits. The operation methods are as follows:
接通電源，停止按鈕“電源指示"燈亮。
Switch on the machine, and the stop button “power indicator" light.
預置實驗所需轉數，只需將撥碼開關撥至所需轉數即可。
Pre-setting the rotation speed needed by the experiment should simply dial the dip switch to the desired rotation speed.
按“啟動按鈕"棒磨機開始運轉并自動計數，“運轉指示"燈亮。當運轉到撥碼開關預置轉速與計數器顯示轉數一致時，棒磨機停止運轉。
Press “Start button", and the rod mill begins operating and automatic counting, the “operating instructions" button light. When the preset rotation speed is reached, which is the same with the counter displayed number, the rod mill stops.
在棒磨機運轉期間需要停機時，可按“停止按鈕"。
Press “stop button" when the machine need to be stopped during rotating.
六、使用注意事項
VI. Caution
1.機器必須良好接地。
1. The machine must be well grounded.
2.鋼棒數量、重量和配比要嚴格控制，鋼棒需經常稱重，保證總個數與總重量不變。
2. The number, weight and ratio of the steel rod must be strictly controlled. And the steel rods should be weighed regularly to ensure the total Number and total weight does not change.
3.每次開機前要檢查油杯、減速機（減速機采用潤滑脂潤滑）、軸承等是否有足夠的潤滑油。
3. Every time before working, make sure there is enough oil in the oil cup, speed reducer (reducer uses grease to lubricate), and the bearings.
4.工作完畢后，應及時清理筒襯內殘留的廢礦或其它贓物。
4. After completion, the waste mine and other dirty stuffs within the liner plate.
