Common problems and solutions for bearings of micro-powder mill

Time: 2019-03-20

Everyone knows that bearings are installed in the mill products. In addition to bearing the weight of the grinding chamber, the bearings can also bear the impact of the grinding powder. Therefore, the bearing failure will seriously affect the smooth production of the grinding powder, and the micro-grinding bearing is also Similarly, Master Li of Shanghai Joyal Mining Machinery here and I will talk about the problems and solutions of the bearings of the micro-grinding mill.

Q: What are the parts where the bearings are installed in the micro-grinding?
Master Li: The part of the general mill that is equipped with bearings is divided into two parts, the main part and the classifier. The part of the main part for connecting the reducer to the grinding chamber part is a bearing, and the part of the classifier for driving the classifier blade is also a bearing.

Q: What are the reasons why the bearing parts are prone to failure?
Master Li: The causes of bearing failures are generally as follows, such as poor lubrication, contamination of impurities, improper installation, excessive use, etc.

Q: Which kind of lubrication method does the bearing in this micro-grinding product use?
Master Li: In this machine, the lubrication system is generally manual lubrication, and because the lubricant is important in the normal operation of the bearing, the user needs to lubricate it according to the machine’s instructions.

Q: What are the serious consequences of improper bearing lubrication?
Master Li: General bearing lubrication improperly includes the following situations, such as the presence of dust impurities in the lubricating oil, incomplete lubrication, and poor sealing after lubrication. If the lubricant contains impurities or the sealing effect is not good, the impurities will invade the bearing components, which will increase the friction between the bearing and other components during the movement, which will accelerate the wear of the bearing and eventually lead to the service life of the bearing. Reduce, thereby increasing the user’s grinding production costs.

Q: The fault of the bearing may also be caused by improper installation. In the face of this problem, what needs to be solved?
Master Li: When installing a bearing, it is necessary to ensure the installation level and ensure that the gap between it and other components is within a reasonable distance. If the user tilts when the bearing is installed or taps the bearing with a tool to deform it, it will eventually Affect the normal operation of the bearing, leading to failure.
