Judgment of the Temperature of Ball Mill Equipment’s bearing

Bearing is the very crucial parts of the ball mill equipment. There is strict requirement about the temperature control of the bearing within the industry. If the temperature is too high it will affect the running efficiency and safety of the ball mill equipment.

Usually, when the bearing temperature of ball mill is too high, it can be perceived by the operator manually. At this time, we must pay attention to the whole bearing temperature is complete high or only part of it is high. That will help us to find the specific reasons. After checking the surface phenomena, the next few steps shall be strictly executed by the operator step by step in order to find out the ultimate cause.

First, check whether the wet ball mill lubrication grease is deteriorated or not.

Second, check lubrication points of all parts of ball mill, in order to check whether the adopted oil number is the same as it is shown in the factory instruction book.
 
Third, check whether the ball mill lubrication piping is blocked or not, or it is caused by the leakage of oil because the lubrication oil doesn’t go directly into the lubrication point.

Fourth, the side clearance of ball mill is too small while the clearance between bearing bush and the shaft is too big, which results in lots of touch point and cannot forms even oil film on the bearing bush.

Fifth, the lubrication grease of ball mill’s rolling bearing is too much or too little. Too much grease will form rolling agitation and generate heat which is not easy to radiate. Too few grease will cause poor lubrication. So it is required to add a suitable amount of oil, usually with 1/3 to 1/2 of the bearing gap is appropriate.
Sixth, the sealing device of the hollow shaft at the end of the ball mill grinding body is too tight or the iron rod directly touches the bearing shaft.
