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.
