Operation Notation of the Ball Mill

I  drive method of the ball mill
1, before the operation, we must check all parts according to the the contents itemized ,after confirming trouble-free, we can do the drove preparation.
2, first start the pump, check whether the lubrication points   oil flow and lubrication system are normal or not (before and after the big watts whether oil, the oil is normal).
3, after the lubrication system backs to normal,  we need to check whether exists block phenomenon or not (normal, Ball flip the inertial rotation around the ball mill).
4, on duty staff contact the full-time dispatchers, dispatchers send electrical contact to the substation.
5, invested the thyristor excitation regulator device, regulating voltage to 50V, Current 100A.
6. staff positions strictly confirm the permission to start "signal before they starting.
7, confirm the permission of starting signal, move the control switch on the control box to the" on "position, start the ball mill operation.

II ball mill parking method
1. before stopping the ball mill,we should first stop feeding and close the Watergate.
2, park the mill after dealing with the ores int the machine.
3. After the machine ore processing,  move the control box on the control handle to the "OFF" position, and inform the dispatcher, the dispatcher to notify the substation power outage.
4, stop the pump before stopping run  ball mill
5, stop the thyristor excitation device.

III, ball mill operation notation
1, duo to the lubricant systems breaksdown, excitation device and other reasons , the mill stop working,  the operator should first  move control handle to the "OFF" position, then notify the relevant personnel for inspection, troubleshooting.
2 . Check the entire mill according to the Ammeter, signal indication, half bearing lubrication and motor temperature rise  these situations

IV, ball mill emergency stop and its processing
1 . We should first stop the machine energency when finding these followingsituations:
(1) spoon head drop.
(2) the feeder trough collide loud.
(3) periodically larger sound for gearing out tooth
(4) motor, reducer bearing section abrupt warming, and the temperature is higher than 80 ° C.
2. If appears the emergency stop,we should be notified immediately the ore feeding and spiral classifier feeding.
3, the main bearing temperature abrupt rise higher than 80 ° C, we should use oil to forcely stop the mill, the water can be used to cool bearing outer when necessity, only when the temperature decrease can we stop machine for checking.
4, after the emergency stopping, all electrical switches should be moved to the parking position.
