This problem is users who attach great importance to our simple aspects from the following nine main bearing ball to understand the cause of overheating.

1, ball mill main bearing scraping poor contact with the hollow shaft and main bearings do not meet requirements, resulting in excessive main bearing wear, a lot of heat, causing the spindle

Watts overheating, even Burnt.

2, if the mill type of lubricant used improper selection oily bad, damaged hollow shaft and main bearings, oil viscosity is small, difficult to form a lubricating film.

3, lubrication system problems, cube magnets such as oil rings with oil well, scraping the oil bodies, cloth oil cooler is not installed correctly, there is no oil filter, piping, etc. is not smooth.

4, if the mill operator is not properly grasp the oil level, oil quality, not timely refueling, can not be caused by lack of oil to replace oil mill, oil

Poor. Not a good mill main bearing lubrication, will also happen mill main bearing overheating.

5, the ball screw shaft and the hollow cylinder insulation is not good, the mill cylinder body heat is passed directly to the main bearing.

6, prolonged feeding hot materials, mainly out of the kiln clinker cooling is not sufficient, resulting in high temperature material into the mill, the mill is directly reflected in the high temperature on the main bearing

, Which is more obvious in the summer from June to August.

7, poorly ventilated mill, the mill cylinder body heat from the difficulties, as well as directly to the main bearings.

8, external cooling is not sufficient, a ball mill with water cooling, cooling water circulation main bearing on the one hand, one surface of the cylinder mill cooling, cooling water or cooling water is stopped

Deficiency may cause insufficient cooling, main bearing overheating.

9, there are cracks in the disc magnets main bearing, the bearing cooling water to seep through the cracks in tile surface, undermining the good lubrication, leading to the main bearing overheating.

Yu sent us through the above mill manufacturers skilled workers analysis, we can see that the ball eventually cause various failures main bearing temperature rises, causing

Burnt main bearing overheating even if the mill spindle Burnt us how to do. Therefore, we can detect main bearing through real-time temperature and found fault mill

. When the main bearing temperature anomalies, the alarm signal is given in a timely manner to detect, prevent bush-burning and other serious accidents, to protect the safe operation of equipment.
