Q: my production line more than six months, impact crusher bearing temperature is the most recent high, and sometimes can reach 67 ° C, I ask what reason? What is the solution?

A: The impact crusher is a very important position in crushed stone production line, compared to not only play the role of the gravel, but also played a shaping role, broken jaw and impact crusher, impact crusher greatly improve the finished material the quality of the finished particles are cubic, uniform particle size, internal cracks, the proportion of flaky stone greatly reduced. Under normal operating conditions, impact crusher bearing temperature rise should not exceed 35 ℃, more than 70 ℃ is the abnormal phenomenon, must be shut down immediately, troubleshooting, before restart. You reached 67 ℃, has been basically coming down the critical point, and continue to work in such a state would largely damage the bearings, and even threatening to the rotor spindle, and therefore must seek to resolve.

According to our experience of high bearing temperature reasons may be:

First: Description of the bearing oil, the need for timely refueling, of course, too much fuel to make the bearing heating, refueling, be sure to check the oil level.
Second: the counter-attack to break the spindle at both ends of the bearing is lithium base grease, grease, dirt can also cause bearing heating.
Third: the bearing damage.
: Superstructure tight.
Correspondingly, the solution is:
First: check the oil level is the amount of increase or decrease depending on the circumstances.
Second: cleaning the bearings, replace grease.
Third: the replacement of bearings.
Fourth: to regulate the bolts, and an appropriate degree is appropriate.

In addition, there may be some special cause, do not know that you are using a home machine, the machine itself is a problem, such as the rotor is not well balanced, resulting in the machine vibration is too severe. can also cause the machine to heat up, the bearings will be followed warming. Of course, these are not normal circumstances, the possibility of this situation would not be significant.
