Common problems and treatment measures for ball mill
1, the ball mills operation, there are rules of the beating sound, and sound great. Is part of the liner bolt not tightened, the ball rotates, the ball mill shell liner struck. Parts of ball mill liner under the sound of that,find the loose bolts, further tightening.
2, the mill and the motor bearing temperature rise, more than regulations. Try his hand touched the bearings is local or all of the temperature is too high, several check processing from the following ball.
(1) Check the ball in different parts of the lubrication points, grades of lubricating oil used in the factory manual with the device are the same.
(2) Check whether the ball lubricants and grease deterioration.
(3) Check whether there is blocked pipe mill lubrication, or no direct access to lubrication points,lubricants, fuel shortage caused by fever.
(4) ball mill the side of the gap is too small, the bearing and the shaft of the gap is too large, too many contact points, can not form a uniform bearing on the film.
(5) ball bearing grease too much or too little, too much grease to form heat stirring rolling and not easy to shed heat. Too few poor lubrication, should be required to add a little oil, usually bearing gap of 1 / 3 to 1 /2 more appropriate.
(6) ball mill grinding the ends of the hollow shaft seal tight, or the seal body iron directly in contact with the shaft.

These problems, handle their causes, with the exception of the side of the bearing gap is too small, or the bottom of the contact angle is too large, you must use the hydraulic jack cylinder mill from the top, the side of the bearing from the shaft out of a separate scratch Research tile.
3, ball bearing fever reducer: Bearing Temperature checks in addition, the reducer should check the vent is blocked, to clear the vent.
4, the ball starts the motor with a reducer, the occurrence of vibration, mainly due to:
(1) two rounds of ball coupling gap is too small, can not compensate for the motor at startup, from self-inflicted caused by the magnetic center of runout.
(2) coupling the alignment ball the wrong way, resulting in two-axis misalignment.
(3) No ball coupling bolts tightening relative said, and not the same degree of tightening force.
(4) The ball mill bearing outer ring activities. Treatment: According to the provisions of the gap on the round a good tune, so that the two concentric shafts. Symmetrical with equal torque coupling bolts tightened. Rotor imbalance, it will be to find out ball rotor static balance.
