1. When the ball mill is running, there is a regular tapping sound, and the sound is very loud. Some of the lining bolts are not tightened. When the ball mill rotates, the lining plate strikes the ball mill to grind the cylinder body. Determine the ball mill lining part according to the sound, find the loose bolt and tighten it separately.
2, ball mill and motor bearing temperature rise, exceeding the regulations. If you try to test the bearing by hand or the temperature is too high, check the ball mill from the following items.
(1) Check the lubrication points of each part of the ball mill. The lubricating oil grade used is consistent with the factory manual.
(2) Check if the ball mill lubricant and grease are deteriorated.
(3) Check if the lubrication line of the ball mill is clogged, or the lubricating oil does not directly enter the lubrication point, and the oil quantity is insufficient to cause heat.
(4) The side clearance of the ball mill bush is too small, the gap between the bush and the shaft is too large, and the contact points are too much to form a uniform oil film on the bearing bush.
(5) The ball mill rolling bearing has too much or too little grease, and excessively formed rolling elements agitate the grease to generate heat, and the heat is not easily dissipated. Too little lubrication, the amount of oil should be increased according to the regulations, generally 1/3 to 1/2 of the bearing clearance is more appropriate.
(6) The sealing device of the hollow shaft at both ends of the ball mill body is too tight, or the sealing body iron member is directly in contact with the shaft.
