Test Run and Maintenance of Ball Mills

Ball mill installation is completed, after passing the test, you can empty trial operation. The whole process of the ball mill test run by the skilled ball mill operators responsible for, and strictly abide by the ball mill safety rules.
(1) The continuous operation of air running time is not less than 12-24 hours, the operation found problems should be resolved in time.
(2) The air test machine can be normal load test run. Load test run should be carried out in stages. Load operation should be based on nesting material feeding, to avoid unnecessary wear and tear and damage of the body and cylinder liner of ball mill.
1. Add the appropriate materials and 1/3 the number of balls (maximum ball loading see ball mill map) test run 12-24 hours.
2. Be added up to the number of 2/3 the ball for 24-48 hours.
3. According to the ball mill discharge situation, the output of qualified products, with reference to the ball mill, to determine the actual installed reasonable amount of the ball, step less than 72 hours of commissioning.
(3) The increase of the above load and the length of the trial operation time shall be determined on the basis of the running condition (temperature rise, noise, tooth contact, etc.) of the gears of the large and small gears and the reducer. In the tooth contact accuracy does not meet the design requirements, not at full capacity operation.
(4) During the trial operation, the cooling and lubrication system shall work normally. Main bearings, drive bearings, reducer temperature should be normal.
(5)Into 2/3 the number of ball test run 24-48 hours, should check and tighten all the bolts again.
(6)Do a good job of the commissioning work records.
Ball mill maintenance:
1. Ball mill in the first use and a month after the continuous change must be a lubricant, replace all the lubricants out, and thoroughly clean the ball mill, and then replace the new lubricants. Ball mill in the use of the latter to ensure that every six months running to replace the lubricating oil.
2. Ball mill in the use of lubrication points to regularly monitor the lubrication of all, including the state of lubrication and oil level, frequency of at least four hours.
3.In ball mill operation, the main bearing lubricants, drive shaft, reducer temperature should be maintained at 55 degrees Celsius, the maximum cannot exceed 60 degrees Celsius, or to stop the ball mill operation, and a detailed examination.
4.In the process of ball mill operation to maintain a smooth, no strong vibration, no abnormal noise, no abnormal current fluctuations and other phenomena, such as the above problems, the need for timely inspection and adjustment of the ball mill.
5.Routine maintenance of ball mill need to determine the use of fasteners, fasteners loose and wear, in addition to check whether there is a combination of oil leakage, whether there is leakage and the existence of leakage of ore phenomenon.
