Mill operating high strength, wear the chance of seizures greater direct impact mill operating rates and the use of life, then how in the process of applying the proper protection and maintenance. Mill wear condition of its operations directly resolution power, and thus make the usual ball protection and conservation is essential. First, the usual overhaul a ball mill, a ball mill in the use of each should regularly monitor the smooth points of smooth conditions, including the condition and smooth the oil level, etc., frequency of at least once arrived in 12 hours. 2, ball mill in operation, the main bearing lubricating oil, drive shaft, gear should insist on the temperature below 55 ℃, the maximum can not exceed 60 ℃, otherwise, it should abort the mill job and carry out specific view. 3, ball mill for 5 minutes at boot time point of monitoring the motor current to be shaken condition, including investigation of normal operating conditions the current value, no other abnormal current shake appearance. 4, in the use of a ball mill, the strict requirements of the specific view various parts of the liner bolts are not loose, cracked, linings fall appearance. 5, to reach normal operation gradually feeding, reduced gradually before stopping material may not feed after 5 minutes. Reduction of load on the motor start. 6, the ball should adhere to during the operation smooth, intense vibration, no abnormal noise. Contains survey reducer, motor, disk, etc. convergence appearance, such as found above questions, you need to be on the ball timely view and adjust. 7, ball mill usually protected status to determine the use of fasteners, fasteners are not loose or worn rendered, others still see the contact surface is not a leak, spill condition and is not there is leakage of mineral aggregate representation. 8, the use of ball mill to seasonal wear condition monitoring is to be more severe in the fray quickly replaced. 9, mill work during episodes of any abnormal condition should immediately parking overhaul. Second, the ball mill ball mill maintenance and repair program protection is a common nature of operations, operational role in the resolution of the ball on the direct operating power, in order to be able to detect the existence of doubt mill and safety hazards on the ball for all to view and conclude overhaul program. 1, ball mill liner wear when it should arrive Qi Cheng replacement program, showing severe damage to the lining of the formation of loose bolts should be replaced by program. 2, ball bearing wear is more severe when program replacement. 3, ball mill and out feed screw can be corrected severe abrasion, such as when you want to fix unwanted programs replaced. 4, severe abrasion mill bolt is to be amended, modified program useless to replace.
