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.
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.
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.
