1. Before starting the grinding machine, check whether the connecting bolts are tightened, the gears, the keys of the coupling and the fastening of the ore feeder.
2. Check if the oil in the fuel tank and reducer is sufficient, and whether the oil passage of the tubing is unblocked.
3. Check the debris around the grinding machine and the classifier for obstruction. Then use the crane to turn the ball mill for one week, loosen the ball load and ore in the cylinder, and check the gear meshing condition for abnormal noise.
4, the order of starting is: first start the grinding machine, then start the classifier, after all the normal operation, start to mine.
5, during the operation process:
(1) The grinding machine is not allowed to work under the condition of overload (loading amount) and material supply shortage, and the grinding medium (ball) is added from the feeder inlet regularly and quantitatively during use.
(2) The main bearing should be greased once per shift, and always pay attention to whether the temperature rise is normal, the motor voltage, current, temperature and sound.
(3) Regularly check the tightening degree of the lining screws to prevent accidents caused by looseness, displacement or falling off of the lining.
(4) Check the lubrication of transmission parts such as large and small gears, main bearings and classifier reducers.
(5) Observe whether the front and rear end caps, cylinders, discharge tanks, and classifier overflow troughs are blocked or sand leakage.
(6) Always pay attention to changes in the nature of the ore and take appropriate measures in a timely manner according to the situation.
(7) There must be no hardened material in the feed tank of the combined feeder to prevent damage to other parts during start-up.
6. When stopping the grinding machine
It is necessary to stop the mining machine first, and after the ore in the cylinder is processed, stop the grinding machine motor, raise the spiral surface with the lifting device of the classifier, and finally stop the classifier.
7, overhaul
In order to ensure safe operation and prolong the service life, it is necessary to plan maintenance:
(1) Minor repair: once a month, including temporary accident handling, mainly small change minor, the focus is to replace consumables such as liners, scoop heads, adjust the bearing and gear meshing, repair the leaks.
(2) Medium repair: once a year, make large cleaning and adjustment of various parts of the equipment, and replace a large number of vulnerable parts.
(3) Overhaul: In addition to completing the small and medium-sized repair tasks, focus on replacing and repairing the main parts, such as hollow shafts and large gears.
