How To Prevent The Gear Of Ball Mill From Being Damaged

How to prevent the gear of ball mill from being damaged
Ball mill is one of the main equipment in pre-selection operation, ensuring its stable and efficient operation is of great importance to the whole plant. Because, the granularity of the selected materials depends on the grinding operation, in addition, the whole grinding system is also a very large part of the investment and consumption of the plant, once the ball mill failure, the subsequent beneficiation operation will be affected, not only delay the production task, but also bring huge economic losses, so to ensure the normal and stable operation of the ball mill is the top priority of the plant.
During the operation of the ball mill, there is a fault without any warning, that is, the pinion fracture, after which the automatic protection system of the ball mill will stop, so that the subsequent production workshop cannot be guaranteed to get adequate and qualified pulp, resulting in the suspension of subsequent operations. So in the production process, how to prevent the ball mill pinion damage?
1. Check the record chart of current fluctuation of the ball mill regularly
Ball mill production workshop motor current data displayed in the control cabinet, can be derived from the database of pinion current curve, from the curve can be observed whether the motor current in the rated value fluctuations, fluctuations are often in the normal rated range, ball mill pinion in good condition, if the data occasionally appear a little larger instant current, but not exceed the rated current value, The data indicates that the service life of the pinion of the ball mill is long and the parts are aging. Therefore, the operator of the mill can carry out targeted maintenance and repair operations on the pinion of the ball mill according to the situation.
If the pinion breaks, the current of the motor will increase instantaneously, and the increase value can exceed 15% of the rated value. At this time, it will cause the self-locking of the equipment system, which can effectively protect other equipment in operation.
2. Check the lubrication system of the ball mill regularly and record
The lubrication system of the ball mill is forced lubrication, and the time and amount of each refueling or oil change can be clearly known from the lubrication records of the workshop. Therefore, we should regularly check the lubrication of the equipment, check whether the gear oil in the tank is sufficient, whether the oil is good, whether there are impurities, whether the nozzle is blocked and other conditions and record, if the above situation occurs, it is necessary to improve in time to ensure the normal lubrication of the ball mill, only to ensure the normal operation of the pinion of the ball mill.
