Ball mill wheel mounting method and routine maintenance

Ball mill wheel mounting method and routine maintenance

The large-diameter ring of the energy-saving ball mill has a large outer shape. For the convenience of transportation, the two-ring gear system is made into a factory. The assembled ring gear should generally be mounted on the main bearing and then mounted on the simplified body, so usually The large ring gear installation is to install a half ring gear above the ball mill body, then rotate the ball mill body, turn the first half ring gear to the lower part of the simplified body, and then install the second half ring gear. It can be seen that the installation of the large ring gear of the mill by the usual method must be carried out after the mill main bearing static pressure lubrication system is put into use, and the mill barrel can be rotated. However, since the equipment such as the ball mill lubricating oil station arrived late, in order to put the mill into use as soon as possible, our company decided to install the large ring gear of the ball mill in a non-lubricated state.

Daily maintenance of energy-saving ball mill:

  • 1. All lubricating oil should be released when the rod mill is put into continuous operation for one month, thoroughly cleaned and replaced with new oil. After the combination, the oil is changed every 6 months.
  • 2. The lubrication condition and oil level of each lubrication point should be checked at least every 4 hours.
  • 3. When the mill is running, the temperature rise of the main bearing lubricant does not exceed 55 °C.
  • 4. When the mill is in normal operation, the temperature rise of the transmission bearing and the reducer does not exceed 55 °C, and the height does not exceed 60 °C.
  • 5. The transmission of large and small gears is stable and there is no abnormal noise. If necessary, adjust the gap in time.
  • 6. The ball mill runs smoothly without strong vibration.
  • 7. The motor current should be free from abnormal fluctuations.
  • 8. There is no looseness in each connecting fastener, no oil leakage on the joint surface, no leakage of water, no leakage.
  • 9. The steel ball is added in time according to the wear condition.
  • 10. If abnormal conditions are found, stop the repair immediately. A regular job in the maintenance of the mill.
