Aug 11, 2015· Ball mill preventive maintenance (PM) It is a frequency work to maintain and repair ball mills, AG mills and SAG mills. The maintenance work influences the rotational speed and service life of ball mills. In order to reduce downtime of ball mill, regular examination and timely replacement of the parts should be done.
The number of impacts in primary ball mills are far more frequent but have less magnitude than those experienced in SAG mills. The increased frequency is due to the Increase in charge volume (35 – 40% versus 5 – 10%), higher mill speeds, and the larger number of balls per unit charge weight.
